* demux_mf: use stream API to open list fileswm42019-12-231-15/+28
| | | | | | | | | | mf:// has an obscure feature that lets you pass a list of filenames separated by newlines. Who knows whether anyone is using that. It opened these listfiles with fopen(), so the recent stream origin bullshit doesn't operate on it. Fix this by using the mpv internal stream API instead. Unfortunately there is no fgets(), so write an ad-hoc one. (An implementation of line reading via "stream" is still in demux_playlist, but it's better to keep it quarantined there.)
* stream, demux: redo origin policy thingwm42019-12-201-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mpv has a very weak and very annoying policy that determines whether a playlist should be used or not. For example, if you play a remote playlist, you usually don't want it to be able to read local filesystem entries. (Although for a media player the impact is small I guess.) It's weak and annoying as in that it does not prevent certain cases which could be interpreted as bad in some cases, such as allowing playlists on the local filesystem to reference remote URLs. It probably barely makes sense, but we just want to exclude some other "definitely not a good idea" things, all while playlists generally just work, so whatever. The policy is: - from the command line anything is played - local playlists can reference anything except "unsafe" streams ("unsafe" means special stream inputs like libavfilter graphs) - remote playlists can reference only remote URLs - things like "memory://" and archives are "transparent" to this This commit does... something. It replaces the weird stream flags with a slightly clearer "origin" value, which is now consequently passed down and used everywhere. It fixes some deviations from the described policy. I wanted to force archives to reference only content within them, but this would probably have been more complicated (or required different abstractions), and I'm too lazy to figure it out, so archives are now "transparent" (playlists within archives behave the same outside). There may be a lot of bugs in this. This is unfortunately a very noisy commit because: - every stream open call now needs to pass the origin - so does every demuxer open call (=> params param. gets mandatory) - most stream were changed to provide the "origin" value - the origin value needed to be passed along in a lot of places - I was too lazy to split the commit Fixes: #7274
* demux_mf: fix backward seeking behaviorwm42019-11-171-6/+8
| | | | | | | If SEEK_FORWARD is set, a demuxer should skip to the next frame if the timestamp does not fall on the start of a frame. If that flag is not set, it should always seek to the first frame before the target timestamp (or the first frame in the file).
* demux: return packets directly from demuxer instead of using sh_streamwm42019-09-191-8/+7
| | | | | | | Preparation for other potential changes to separate demuxer cache/thread and actual demuxers. Most things are untested, but it seems to work somewhat.
* build: switch preliminary LGPL mode from v3 to v2.1wm42017-10-051-7/+1
| | | | | | | | | | | iive agreed to relicense things that are still in mpv to LGPLv2.1. So change the licenses of the affected files, and rename the configure switch for LGPL mode to --enable-preliminary-lgpl2. (The "preliminary" part will probably be removed from the configure switch soon as well.) Also player/main.c hasn't had GPL parts since a few commits ago.
* {demux_mf,osdep/io}: disable glob usage when it is not availableJan Ekström2017-08-051-0/+2
| | | | | | | | This currently is only limited to Android. Its stdlib contains the things that mpv's POSIX check checks for, but unfortunately not glob(). This fixes Android compilation broken in 70a70b9da .
* build: replace glob() check and assume it's always in POSIXwm42017-06-291-2/+0
| | | | | POSIX requires glob(), so no need to check for it. Together with the fact that we can emulate glob() on Windows, glob() is always available.
* demux_mf, stream_mf: change license to LGPLwm42017-06-241-7/+13
| | | | | | | | | | | | | | | | | | | cehoyos, who did not agree to the relicensing, added bcb5c78ce3. If there was copyright, we consider it gone, because the table changed. It does not map file extension to a FourCC anymore, and codecs.conf is gone. The new mapping is a libavcodec codec name (happens to be the same as the file extension). The same applies to commits 60ecafec, b749836b, 5b3e3be1. None of these authors were contacted. These were before the code was replaced with a table (in d0326807). The parts outside of demux_mf.c were removed a long time ago. Like in the previous comment, we don't think any copyright applies at least to the new code (at least after the FourCC removal). iive authored 0aa37a0d, which is probably still left in some form, and makes demux_mf.c "LGPL 3 or later". stream_avdevice.c (unrelated) has been marked as LGPL before.
* demux: get rid of DEMUXER_CTRL_GET_TIME_LENGTHwm42017-06-201-15/+1
| | | | | | | | | | | | Similar purpose as f34e1a0deea45e. Somehow this is much more natural too, and needs less code. This breaks runtime updates to duration. This could easily be fixed, but no important demuxer does this anyway. Only demux_raw and demux_disc might (the latter for BD/DVD). For the latter it might actually have some importance when changing titles at runtime (I guess?), but guess what, I don't care.
* demux: replace custom return codes with CONTROL_ oneswm42017-06-191-2/+2
| | | | | | | | This is more uniform, and potentially gets rid of some past copyrights. It might be that this subtly changes caching behavior (it seems before this, it synced to the demuxer if the length was unknown, which is not what we want.)
* stream: get rid of streamtype enumwm42017-02-021-2/+3
| | | | | | | | | 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.
* demux: do not access global optionswm42016-09-061-4/+10
| | | | | | | | | | | | | | | | | 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.
* video/audio: always provide "proper" timestamps to libavcodecwm42016-08-191-0/+1
| | | | | | | | | | | | | | | | | | | Instead of passing through double float timestamps opaquely, pass real timestamps. Do so by always setting a valid timebase on the AVCodecContext for audio and video decoding. Specifically try not to round timestamps to a too coarse timebase, which could round off small adjustments to timestamps (such as for start time rebasing or demux_timeline). If the timebase is considered too coarse, make it finer. This gets rid of the need to do this specifically for some hardware decoding wrapper. The old method of passing through double timestamps was also a bit questionable. While libavcodec is not supposed to interpret timestamps at all if no timebase is provided, it was needlessly tricky. Also, it actually does compare them with AV_NOPTS_VALUE. This change will probably also reduce confusion in the future.
* demux: remove relative seekingwm42016-02-281-6/+3
| | | | | | | | | | | | | | | | | | | Ever since a change in mplayer2 or so, relative seeks were translated to absolute seeks before sending them to the demuxer in most cases. The only exception in current mpv is DVD seeking. Remove the SEEK_ABSOLUTE flag; it's not the implied default. SEEK_FACTOR is kept, because it's sometimes slightly useful for seeking in things like transport streams. (And maybe mkv files without duration set?) DVD seeking is terrible because DVD and libdvdnav are terrible, but mostly because libdvdnav is terrible. libdvdnav does not expose seeking with seek tables. (Although I know xbmc/kodi use an undocumented API that is not declared in the headers by dladdr()ing it - I think the function is dvdnav_jump_to_sector_by_time().) With the current mpv policy if not giving a shit about DVD, just revert our half-working seek hacks and always use dvdnav_time_search(). Relative seeking might get stuck sometimes; in this case --hr-seek=always is recommended.
* demux_mf: only use glob() if it is availableJan Ekström2016-02-101-0/+2
| | | | | The only other place where glob() is used is windows-specific and for windows mpv includes its own glob wrapper.
* demux: merge sh_video/sh_audio/sh_subwm42016-01-121-9/+8
| | | | | | | | | | This is mainly a refactor. I'm hoping it will make some things easier in the future due to cleanly separating codec metadata and stream metadata. Also, declare that the "codec" field can not be NULL anymore. demux.c will set it to "" if it's NULL when added. This gets rid of a corner case everything had to handle, but which rarely happened.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-111-1/+1
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* demux_mf: fix previous commitwm42015-12-231-5/+7
| | | | It was total crap.
* demux: remove weird tripple-buffering for the sh_stream listwm42015-12-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The demuxer infrastructure was originally single-threaded. To make it suitable for multithreading (specifically, demuxing and decoding on separate threads), some sort of tripple-buffering was introduced. There are separate "struct demuxer" allocations. The demuxer thread sets the state on d_thread. If anything changes, the state is copied to d_buffer (the copy is protected by a lock), and the decoder thread is notified. Then the decoder thread copies the state from d_buffer to d_user (again while holding a lock). This avoids the need for locking in the demuxer/decoder code itself (only demux.c needs an internal, "invisible" lock.) Remove the streams/num_streams fields from this tripple-buffering schema. Move them to the internal struct, and protect them with the internal lock. Use accessors for read access outside of demux.c. Other than replacing all field accesses with accessors, this separates allocating and adding sh_streams. This is needed to avoid race conditions. Before this change, this was awkwardly handled by first initializing the sh_stream, and then sending a stream change event. Now the stream is allocated, then initialized, and then declared as immutable and added (at which point it becomes visible to the decoder thread immediately). This change is useful for PR #2626. And eventually, we should probably get entirely of the tripple buffering, and this makes a nice first step.

* demux_mf: move mf.c contents to demux_mf.cwm42014-12-291-2/+122
| | | | | | | | | There's no reason why parts of this demuxer would be in a separate source file. The existence of this code is already somewhat questionable anyway, so it may as well be dumped into a single file. Even stranger that demux.c included mf.h for no reason (it was an artifact from 2002 when the architecture was uncleaner).
* demux_mf: add probing by mime typewm42014-12-221-1/+5
| | | | Reuses the mime type table introduced in the previous commit.
* demux: gracefully handle packet allocation failureswm42014-09-161-4/+6
| | | | Now the packet allocation functions can fail.
* demux_mf: allow seeking past the endwm42014-07-301-1/+1
| | | | How's this for a corner case.
* demux: fix timestamp type for seek callswm42014-07-211-1/+1
| | | | | mpv/mplayer2/MPlayer use double for timestamps, but the demuxer API used float.
* build: include <strings.h> for strcasecmp()wm42014-07-101-0/+1
| | | | | | | It happens to work without strings.h on glibc or with _GNU_SOURCE, but the POSIX standard requires including <strings.h>. Hopefully fixes OSX build.
* demux: minor simplification to internal APIwm42014-07-051-1/+1

* demux: mp_msg conversionswm42013-12-211-6/+4
| | | | | | | The TV code pretends to be part of stream/, but it's actually demuxer code too. The audio_in code is shared between the TV code and stream_radio.c, so stream_radio.c needs a small hack until stream.c is converted.

* demux: remove gsh field from sh_audio/sh_video/sh_subwm42013-11-231-1/+1
| | | | | | | | | This used to be needed to access the generic stream header from the specific headers, which in turn was needed because the decoders had access only to the specific headers. This is not the case anymore, so this can finally be removed again. Also move the "format" field from the specific headers to sh_stream.

* demux: make determining seek capability genericwm42013-11-031-0/+1
| | | | | | | | | | | | | | | | Instead of having each demuxer do it (only demux_mkv actually did...), let generic code determine whether the file is seekable. This requires adding exceptions to demuxers where the stream is not seekable, but the demuxer is. Sort-of try to improve handling of unseekable files in the player. Exit early if the file is determined to be unseekable, instead of resetting all decoders and then performing a pointless seek. Add an exception to allow seeking if the file is not seekable, but the stream cache is enabled. Print a warning in this case, because seeking outside the cache (which we can't prevent since the demuxer is not aware of this problem) still messes everything up.
* demux: remove movi_start/movi_end fieldswm42013-11-031-4/+0
| | | | | | | Pointless, using stream->start_pos/end_pos instead. demux_mf was the only place where this was used specially, but we can rely on timestamps instead for this case.
* demux: remove unused audio_delay parameter from demux_seek()wm42013-08-221-1/+2

* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-1/+1

* demux: assume correct-pts mode by defaultwm42013-07-121-3/+0
| | | | | | | | All demuxers make a reasonable effort to set packet timestamps, and thus support correct-pts mode. This commit also implicitly switches demux_rawvideo to correct-pts mode. We still allow demuxers to disable correct-pts mode in theory.
* demux: remove useless author/comment fieldswm42013-07-121-4/+1
| | | | Same deal as with previous commit.
* demux: rewrite probing and demuxer initializationwm42013-07-121-45/+32
| | | | | | | | | | | | | | Get rid of the strange and messy reliance on DEMUXER_TYPE_ constants. Instead of having two open functions for the demuxer callbacks (which somehow are both optional, but you can also decide to implement both...), just have one function. This function takes a parameter that tells the demuxer how strictly it should check for the file headers. This is a nice simplification and allows more flexibility. Remove the file extension code. This literally did nothing (anymore). Change demux_lavf so that we check our other builtin demuxers first before libavformat tries to guess by file extension.
* core: change open_stream and demux_open signaturewm42013-07-121-1/+1
| | | | | | | | | | | This removes the dependency on DEMUXER_TYPE_* and the file_format parameter from the stream open functions. Remove some of the playlist handling code. It looks like this was needed only for loading linked mov files with demux_mov (which was removed long ago). Delete a minor bit of dead network-related code from stream.c as well.
* demux: change signature of open functions, cleanupswm42013-07-111-18/+19

* core: don't access demux_stream outside of demux.c, make it privatewm42013-07-111-7/+3
| | | | | | | | | | | | | | | | | | | Generally remove all accesses to demux_stream from all the code, except inside of demux.c. Make it completely private to demux.c. This simplifies the code because it removes an extra concept. In demux.c it is reduced to a simple packet queue. There were other uses of demux_stream, but they were removed or are removed with this commit. Remove the extra "ds" argument to demux fill_buffer callback. It was used by demux_avi and the TV pseudo-demuxer only. Remove usage of d_video->last_pts from the no-correct-pts code. This field contains the last PTS retrieved after a packet that is not NOPTS. We can easily get this value manually because we read the packets ourselves. Reuse sh_video->last_pts to store the packet PTS values. It was used only by the correct-pts code before, and like d_video->last_pts, it is reset on seek. The behavior should be exactly the same.
* demux: remove separate arrays for audio/video/sub streams, simplifywm42013-07-081-3/+0
| | | | | | | | | | | | These separate arrays were used by the old demuxers and are not needed anymore. We can simplify track switching as well. One interesting thing is that stream/tv.c (which is a demuxer) won't respect --no-audio anymore. It will probably work as expected, but it will still open an audio device etc. - this is because track selection is now always done with the runtime track switching mechanism. Maybe the TV code could be updated to do proper runtime switching, but I can't test this stuff.
* demux: remove some old stream header functionswm42013-07-081-1/+2

* stream: remove padding parameter from stream_read_complete()wm42013-06-231-1/+1
| | | | | | | | Seems like a completely unnecessary complication. Instead, always add a 1 byte padding (could be extended if a caller needs it), and clear it. Also add some documentation. There was some, but it was outdated and incomplete.
* demux_mf: fix crashes when '*' matches directorieswm42013-03-191-3/+6
| | | | | | | Doing 'mpv mf://*' in a file with directories would crash, because even though directories are skipped, the corresponding file entry is just left at NULL, leading to a segfault on access. So explicitly skip NULL entries.
* core: use playback time to determine playback percent positionwm42013-02-261-6/+0
| | | | | | | | | | | | | The percent position is used for the OSD, the status line, and for the OSD bar (shown on seeks). By default, the PTS of the last demuxed packet was used to calculate it. This led to a "jumpy" display when the percentage value (casted to int) was changing. The reasons for this were the presence of video frame reordering (packet PTS is not monotonic), or getting PTS values from different streams (like audio/subs). Since these rely on PTS values and correct file durations anyway, simplify it by calculating it with the current playback position in mplayer.c instead.
* demux_mf: add some more image formatswm42013-02-241-1/+15
| | | | And fix the comment about fourccs.
* demux_mf: support .xbmwm42013-02-241-0/+1
| | | | | | | And support the PIX_FMT_MONOWHITE pixel format. (This is really weird: unlike PIX_FMT_MONOBLACK, it uses white pixels. I have no idea why libavcodec doesn't just convert the pixel format on the fly, instead of bothering everyone with really special pixel formats.)
* demux_mf: map to codecs directlywm42013-02-241-36/+35
| | | | Instead of going through FourCCs and codec_tags.c.
* demux_mf: fix breakage after commit 4d016a9wm42013-02-171-0/+1

* demux_mf: allow displaying single image files, various cleanupswm42012-11-161-76/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable autoprobing for demux_mf, so that image files can be directly displayed with e.g. "mpv file.jpg --pause". (The --pause switch is needed to prevent the window from closing immediately.) Since demux_mf doesn't have any real file format probing and goes by file extension only, move the demuxer down the demuxer list to ensure it's checked last. (ffmpeg's demux_mf equivalent, "image2", probes by file extensions too, and there doesn't seem to be anything that can probe typical image file formats from binary data.) Remove the --mf "w" and "h" suboptions. Don't pass the width/height to the video stream header. Both of these are useless, because the decoder reads the real image size at a later point from the file headers. Remove setting the BITMAPINFOHEADER as well, as vd_lavc doesn't need this. Enable --correct-pts by default. This fixes displaying a single image with vo_vdpau (as mentioned by uau). Keep around a pointer to the sh_video stream header instead of accessing demuxer->video->sh_video. Fixes a crash when deselecting the video track. Note that the format probing is incorrect when opening images from HTTP locations. File extensions don't have to match the actual file format. A correct implementation would require to check the MIME type, or to probe the binary data correctly.
* Rename directories, move files (step 2 of 2)wm42012-11-121-2/
