* stream: move stream_read_line to demux_playlist.cwm42019-10-311-2/+0
| | | | | demux_playlist.c is the only remaining user of this. Not sure if it should stay this way, but for now I'll say yes.
* stream: stop accessing buffer internals in stream_read_line()wm42019-10-311-0/+1
| | | | | Getting this out of the way in preparation for reworking stream internals.
* demux: restore some of the DVD/BD/CDDA interaction layerswm42019-10-031-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This partially reverts commit a9d83eac40c94f44d19fab7b6955331f10efe301 ("Remove optical disc fancification layers"). Mostly due to the timestamp crap, this was never really going to work. The playback layer is sensitive to timestamps, and derives the playback time directly from the low level packet timestamps. DVD/BD works differently, and libdvdnav/libbluray do not make it easy at all to compensate for this. Which is why it never worked well, but not doing it at all is even more awful. demux_disc.c tried this and rewrote packet timestamps from low level TS to playback time. So restore demux_disc.c, which should bring behavior back to the old often non-working but slightly better state. I did not revert anything that affects components above the demuxer layer. For example, the properties for switching DVD angles or listing disc titles are still gone. (Disc titles could be reimplemented as editions. But not by me.) This commit modifies the reverted code a bit; this can't be avoided, because the internal API changed quite a bit. The old seek resync in demux_lavf.c (which was a hack) is replaced with a hack. SEEK_FORCE and demux_params.external_stream are new additions. Some of this could/should be further cleaned up. If you don't want "proper" DVD/BD support to disappear, you should probably volunteer. Now why am I wasting my time for this? Just because some idiot users are too lazy to rip their ever-wearing out shitty physical discs? Then why should I not be lazy and drop support completely? They won't even be thankful for me maintaining this horrible garbage for no compensation.
* stream: rearrange open functionswm42019-09-291-4/+13
| | | | | | | | | | | | | | | | Add yet another variant of the stream open function. This time, make it so that it's possible to add new open parameters in an extendable way, which should put an end to having to change this every other year. Effectively get rid of the overly special stream_create_instance() function and use the new one instead, which requires changes in stream_concat.c and stream_memory.c. The function is still in private in stream.c, but I preferred to make the mentioned users go through the new function for orthogonality. The error handling (mostly logging) was adjusted accordingly. This should not have any functional changes. (To preempt any excuses, I didn't actually test stream_concat and stream_memory.)
* stream: add a generic concat implementationwm42019-09-191-0/+4
| | | | | | This is not available to users. It can be used only though the stream_concat_open(). It's unused yet; to be used in the following commit.
* stream: create memory streams in more straightforward waywm42019-09-191-4/+9
| | | | | | | | | | | | | | | Instead of having to rely on the protocol matching, make a function that creates a stream from a stream_info_t directly. Instead of going through a weird indirection with STREAM_CTRL, add a direct argument for non-text arguments to the open callback. Instead of creating a weird dummy mpv_global, just pass an existing one from all callers. (The latter one is just an artifact from the past, where mpv_global wasn't available everywhere.) Actually I just wanted a function that creates a stream without any of that bullshit. This goal was slightly missed, since you still need this heavy "constructor" just to setup a shitty struct with some shitty callbacks.
* stream: redo buffer handling and allow arbitrary size for stream_peek()wm42019-09-191-6/+4
| | | | | | | | | | | | | | | | struct stream used to include the stream buffer, including peek buffer, inline in the struct. It could not be resized, which means the maximum peek size was set in stone. This meant demux_lavf.c could peek only so much data. Change it to use a dynamic buffer. Because it's possible, keep the inline buffer for default buffer sizes (which are basically always used outside of file opening). It's unknown whether it really helps with anything. Probably not. This is also the fallback plan in case we need something like the old stream cache in order to deal with mp4 + unseekable http: the code can now be easily changed to use any buffer size.
* stream_libarchive: remove base filename stuffwm42019-09-191-3/+0
| | | | | | | | Apparently this was so that when playing a video file from a .rar file, it would load external subtitles with the same name (instead of looking for mpv's rar:// mangled URL). This was requested on github almost 5 years ago. Seems like a weird feature, and I don't care. Drop it, because it complicates some in progress change.
* demux, stream: remove old rar support in favor of libarchivewm42019-09-131-1/+1
| | | | | | The old rar code could do uncompressed rar, libarchive supports at least some rar compression algorithms. There is no need to keep the old rar code.
* stream: remove some more optical disc leftoverswm42019-09-131-14/+0

* Remove classic Linux analog TV support, and DVB runtime controlswm42019-09-131-24/+0
| | | | | | | | | | | | | | | | | | | | | | | | Linux analog TV support (via tv://) was excessively complex, and whenever I attempted to use it (cameras or loopback devices), it didn't work well, or would have required some major work to update it. It's very much stuck in the analog past (my favorite are the frequency tables in frequencies.c for analog TV channels which don't exist anymore). Especially cameras and such work fine with libavdevice and better than tv://, for example: mpv av://v4l2:/dev/video0 (adding --profile=low-latency --untimed even makes it mostly realtime) Adding a new input layer that targets such "modern" uses would be acceptable, if anyone is interested in it. The old TV code is just too focused on actual analog TV. DVB is rather obscure, but has an active maintainer, so don't remove it. However, the demux/stream ctrl layer must go, so remove controls for channel switching. Most of these could be reimplemented by using the normal method for option runtime changes.
* stream: remove BD/DVD/CDDA sector size alignmentwm42019-09-131-2/+0
| | | | | | This was possibly needed by libdvdread, and/or old CD drivers on some system. It still works with on-filesystem DVD and BD test images, so this can go.
* Remove optical disc fancification layerswm42019-09-131-17/+4
| | | | | | | | | | | | | | | | | This removes anything related to DVD/BD/CD that negatively affected the core code. It includes trying to rewrite timestamps (since DVDs and Blurays do not set packet stream timestamps to playback time, and can even have resets mid-stream), export of chapters, stream languages, export of title/track lists, and all that. Only basic seeking is supported. It is very much possible that seeking completely fails on some discs (on some parts of the timeline), because timestamp rewriting was removed. Note that I don't give a shit about optical media. If you want to watch them, rip them. Keeping some bare support for DVD/BD is the most I'm going to do to appease the type of lazy, obnoxious users who will care. There are other players which are better at optical discs.
* demux, stream: readd cache-speed in some other formwm42018-12-061-0/+4
| | | | it's more like an input speed rather than a cache speed, but who cares.
* demux, stream: rip out the classic stream cachewm42018-08-311-27/+0
| | | | | | The demuxer cache is the only cache now. Might need another change to combat seeking failures in mp4 etc. The only bad thing is the loss of cache-speed, which was sort of nice to have.
* command: whitelist some blocking accesses for certain demuxers/streamswm42018-05-241-0/+1
| | | | | | | | | | | | | | | | | | | | | The properties/commands touched in this commit are all for obscure special inputs (BD/DVD/DVB/TV), and they all block on the demuxer/stream layer. For network streams, this blocking is very unwelcome. They will affect playback and probably introduce pauses and frame drops. The player can even freeze fully, and the logic that tries to make playback abortable even if frozen complicates the player. Since the mentioned accesses are not needed for network streams, but they will block on network streams even though they're going to fail, add a flag that coarsely enables/disables these accesses. Essentially it establishes a whitelist of demuxers/streams which support them. In theory you could to access BD/DVD images over network (or add such support, I don't think it's a thing in mpv). In these cases these controls still can block and could even "freeze" the player completely. Writing to the "program" and "cache-size" properties still can block even for network streams. Just don't use them if you don't want freezes.
* misc: move mp_cancel from stream.c to thread_tools.cwm42018-05-241-8/+0
| | | | | | | | | | | | It seems a bit inappropriate to have dumped this into stream.c, even if it's roughly speaking its main user. At least it made its way somewhat unfortunately to other components not related to the stream or demuxer layer at all. I'm too greedy to give this weird helper its own file, so dump it into thread_tools.c. Probably a somewhat pointless change.
* stream: use native libavformat reconnection featurewm42018-01-041-1/+0
| | | | | | | | | | | | | | | | | | Remove our own hacky reconnection code, and use libavformat's feature for that. It's disabled by default, and until recently it did not work too well. This has been fixed in recent ffmpeg git master[1], so there's no reason to keep our own code. [1] FFmpeg/FFmpeg@8a108bdea06fac43af9f44b6d2538f357451167a We set "reconnect_delay_max" to 7, which limits the maximum time it waits. Since libavformat doubles the wait time on each reconnect attempt (starting with 1), and stops trying to reconnect once the wait time is over the reconnect_delay_max value, this allows for 4 reconnection attempts which should add to 11 seconds maximum wait time. The default is 120, which seems too high for normal playback use. (The user can still override these parameters with --stream-lavf-o.)
* stream: change license to LGPLwm42017-06-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All relevant authors have agreed. There are two exceptions, patches by authors who could not be reached. This commit tries to remove their copyright. a0f08fbe: messes with the seeking code corner cases. The EOF flag logic was changed at some point, and always had a flaky history (see e.g. 347cf972 50274ca3 70411f27 5999efb9 0d5e6084 ff08d0c3 2e2f77e3 de5566f0 9554a844, all which happened after that patch, MPlayer ones without that patch). I claim that all of the copyright the patch might have added is gone. Except the message in stream_seek(), which this commit removes. The other code removed/changed in stream_seek() is probably not from that patch, but it doesn't hurt to be sure, and also makes it more readable. (It might change the behavior so that sometimes the eof flag is set after a seek, but it doesn't matter here.) 2aa6acd9: it looks like the seek_forward() modified by this patch was later moved to stream.c and renamed to stream_skip_read() in a790f2133. (Looking closer at it, it was actually modified again a bunch of times, fixing the logic.) I rewrote it in this commit. The code ended up rather similar, which probably could lead to doubts whether this was done properly, but I guess the reader of this will just have to believe me. I knew what stream_skip_read() was supposed to do (which was reinforced when I tried to replace it on the caller side), without reading the pre-existing code in detail. I had to "relearn" the logic how buf_pos and bug_len work - it was actually easy to see from stream_read_char() how to skip the data, essentially by generalizing its logic from 1 byte to N bytes. From the old code I only "used" the fact that it's obviously a while(len>0) look, that has to call stream_fill_buffer repeatedly to make progress. At first I actually didn't use stream_fill_buffer_by(), but the variant without _by, but readded it when I checked why the old code used it (see cd7ec016e7). This has to be good enough. In the end, it's hard to argue that this could be implemented in a way not using such a loop. Other than this, I could add the usual remarks about how this code was not modularized in the past, and how stream.c contained DVD code, and how this was later modularized, moving the copyright to other files, and so on. Also, if someone wrote a stream module, and was not asked about LGPL relicensing, we don't consider the entry in stream_list[] copyrightable.
* stream: get rid of streamtype enumwm42017-02-021-16/+2
| | | | | | | | | Because it's kind of dumb. (But not sure if it was worth the trouble.) For stream_file.c, we add new explicit fields. The rest are rather special uses and can be killed by comparing the stream impl. name. The changes to DVD/BD/CD/TV are entirely untested.
* stream: better method signal caching, rename weird uncached_stream fieldwm42017-02-021-1/+2
| | | | | | | | "uncached_stream" is a pretty bad name. It could be mistaken for a boolean, and then its meaning would be inverted. Rename it. Also add a "caching" field, which signals that the stream is a cache or reads from a cache. This is easier to understand and more flexible.
* player: remove --stream-capture option/propertywm42017-01-211-5/+0
| | | | | | | | | | | | | | | This was excessively useless, and I want my time back that was needed to explain users why they don't want to use it. It captured the byte stream only, and even for types of streams it was designed for (like transport streams), it was rather questionable. As part of the removal, un-inline demux_run_on_thread() (which has only 1 call-site now), and sort of reimplement --stream-dump to write the data directly instead of using the removed capture code. (--stream-dump is also very useless, and I struggled coming up with an explanation for it in the manpage.)
* demux, stream: add option to prevent opening referenced fileswm42016-12-041-0/+1
| | | | Quite irresponsibly hacked together. Sue me.
* stream, demux, config: remove some dead/unneeded option-related codewm42016-09-091-13/+0
| | | | | | | | | | This has all been made unnecessary recently. The change not to copy the global option struct in particular can be made because now nothing accesses the global options anymore in the demux and stream layers. Some code that was accidentally added/changed in commit 5e30e7a0 is also removed, because it was simply committed accidentally, and was never used.
* stream_dvd, stream_dvdnav: remove weird option parsing stuffwm42016-09-081-0/+7
| | | | | | Same deal as with stream_bluray. Untested because I don't give a fuck about your shitty DVDs.
* demux: do not access global optionswm42016-09-061-3/+2
| | | | | | | | | | | | | | | | | Don't access MPOpts directly, and always use the new m_config.h functions for accessing them in a thread-safe way. The goal is eventually removing the mpv_global.opts field, and the demuxer/stream-layer specific hack that copies MPOpts to deal with thread-safety issues. This moves around a lot of options. For one, we often change the physical storage location of options to make them more localized, but these changes are not user-visible (or should not be). For shared options on the other hand it's better to do messy direct access, which is worrying as in that somehow renaming an option or changing its type would break code reading them manually, without causing a compilation error.
* client API: add stream_cb API for user-defined stream implementationsAman Gupta2016-08-071-0/+1
| | | | | | Based on #2630. Some heavy changes by committer. Signed-off-by: wm4 <wm4@nowhere>
* cache: use a single STREAM_CTRL for various cache infowm42016-03-291-4/+9
| | | | | | | | Instead of having a separate for each, which also requires separate additional caching in the demuxer. (The demuxer adds an indirection, since STREAM_CTRLs are not thread-safe.) Since this includes the cache speed, this should fix #3003.
* command: add cache-speed propertywm42016-03-201-0/+1
| | | | | | | Should reflect I/O speed. This could go into the terminal status line. But I'm not sure how to put it there, since it already uses too much space, so it's not there yet.
* cache: remove unused STREAM_CTRL_RESUME_CACHEwm42016-03-031-1/+0
| | | | Went way with DVD/BD menu support.
* cache: add mechanism for disabling readaheadwm42016-01-181-0/+1
| | | | Will be used in a following commit.
* player, stream_dvb: implement dvb-channel-name property.Oliver Freyermuth2016-01-141-0/+2
| | | | | | | | | On read, it returns the name of the current DVB program, on write, it triggers a channel-switch to the program if it is found in the channel list of the currently active card. Compared to the dvb-channel property which already exists and is a pair of integers (card + channel number) this has the limitation of not switching the card, but is probably of much more common use.
* stream: provide a stream_get_size() convenience functionwm42015-08-181-0/+1
| | | | | And use it everywhere, instead of retrieving the size manually. Slight simplification.
* stream: remove remaining DVD/BD menu definitionswm42015-08-031-2/+0
|
* vo_opengl: add support for custom shadersNiklas Haas2015-05-271-0/+2
|
* command: add protocol-list propertywm42015-05-231-0/+1
| | | | Fixes #1972.
* player: allow playing directorieswm42015-04-171-0/+1
| | | | | | | | | | | If a directory is encountered, replace it with its contents in the internal playlist. This is messed into demux_playlist.c, because why not. STREAMTYPE_DIR could be avoided by unconditonally trying opendir() in demux_playlist.c, but it seems nicer not to do weird things like calling it on real files. This does not work on Windows, because msvcrt is retarded.
* Update license headersMarcin Kurczewski2015-04-131-5/+4
| | | | Signed-off-by: wm4 <wm4@nowhere>
* player: refine rar:// playlist-safety handlingwm42015-03-021-1/+0
| | | | | | | | | | | | It was possible to make the player play local files by putting rar:// links into remote playlists, and some other potentially unsafe things. Redo the handling of it. Now the rar-redirector (the thing in demux_playlist.c) sets disable_safety, which makes the player open any playlist entries returned. This is fine, because it redirects to the same file anyway (just with different selection/interpretation of the contents). On the other hand, rar:// itself is now considered fully unsafe, which means that it is ignored if found in normal playlists.
* stream: remove stream filter conceptwm42015-02-271-3/+0
| | | | Unused since the previous commit. (Apparently it was a stupid idea.)
* stream: get rid of remaining uses of the end_pos fieldwm42015-02-061-2/+1
| | | | | | | | Most things stopped using this field for better support of growing files. Go through the trouble to repalce the remaining uses, so it can be removed. Also move the "streaming" field; saves 4 bytes (wow!).
* stream: minor cleanupswm42015-02-061-2/+2
| | | | | | | | | | | | | | | | Fix return types and return values to make them more consistent. Some reformatting and making code more concise. In stream_reconnect(), avoid the additional mp_cancel_test() call by moving the "connection lost" message below the mp_cancel_wait() call, which effectively leads to the same behavior when the stream was already canceled. (The goal is not to show the message in this case.) Merge stream_seek_long() into stream_seek(). It was the only caller. Always clear the eof flag on seeks. Reduce access to stream internals in cache.c and stream_lavf.c.
* stream: slightly improve reconnect behaviorwm42015-02-061-0/+1
| | | | | Wait for a longer time between reconnects. Introdeuce and use mp_cancel_wait(), so that quitting is still immediate.
* command: add dummy get implementation for tv-channel propertywm42015-02-021-0/+1
| | | | | A small cosmetic change with the effect that pressing 'k' shows "unavailable" instead of "error" (even if no TV code is active).
* command, dvd: add property which returns list of DVD titleswm42014-12-131-22/+35
| | | | | | | | | This was requested. It seems libdvdread can't get the duration for titlesets other than the currently opened title. The data structures contain dangling pointers for these, and MPlayer works this around by opening every title separately for the purpose of dumping the title list.
* stream: reduce ifdeffery for win32 somewhatwm42014-11-181-4/+1
| | | | Remove the ones which are not strictly needed.
* stream: signal a Windows event object on cancelJames Ross-Gowan2014-11-181-0/+4
| | | | | This will be used in the following commit to cancel subprocesses started by Lua.
* demux_lavf: mark as seekable if protocol supports seeking by timewm42014-10-301-0/+1
| | | | | | | | | | | | Basically, this will mark the demuxer as seekable with rtmp* and mmsh protocols. These protocols have network-level time seeking, and whether you can seek on the byte level does not matter. Until now, seeking was typically only enabled because of the cache, and a (nonsensical) warning was shown accordingly. It still could happen that the server doesn't actually support thse requests (or simply rejects them), so this is somewhat imperfect.
* lua: add an utility function for starting processeswm42014-10-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because 1) Lua is terrible, and 2) popen() is terrible. Unfortunately, since Unix is also terrible, this turned out more complicated than I hoped. As a consequence and to avoid that this code has to be maintained forever, add a disclaimer that any function in Lua's utils module can disappear any time. The complexity seems a bit ridiculous, especially for a feature so far removed from actual video playback, so if it turns out that we don't really need this function, it will be dropped again. The motivation for this commit is the same as with 8e4fa5fc. Note that there is an "#ifndef __GLIBC__". The GNU people are very special people and thought it'd be convenient to actually declare "environ", even though the POSIX people, which are also very special people, state that no header declares this and that the user has to declare this manually. Si
