* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-199-63/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.
* global: add client API pointer to library handlewm42016-01-151-0/+1
| | | | | | | Makes the next commit simpler. It's probably a bad idea to add more fields to the global state, but on the other hand the client API state is pretty much per-instance anyway. It also will help with things like the proposed libmpv custom stream API.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-116-6/+6
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* common: add mp_tag_str() utility functionwm42016-01-112-0/+20

* common: allow "\/" as escape sequencewm42016-01-081-1/+2
| | | | | | | | | | | | | mp_parse_escape() is used by the JSON parser in json.c, and JSON allows escaping "/" (solidus). Although it makes no sense, apparently Javascript traditionally allowed that as escape sequence for working around issues with embedding Javascript in HTML. (Or something like this must have been the history of this issue.) Since it's valid in Javascript, it had to be valid in JSON as well, and JSON explicitly specifies it as valid escape. Fixes #2694.
* player: make watch later/resume work when "playing" directorieswm42016-01-062-0/+18
| | | | | | | | | | | | | | If you do "mpv /bla/", and then branch out into sub-directories using playlist navigation, and then used quit and watch later, then playing the same directory did not resume from the previous point. This was because resuming is based on the path hash, so a path prefix can't be detected when resuming the parent directory. Solve this by writing each path prefix when playing directories is involved. (This includes all parent paths, so interestingly, "mpv /" would also resume in the above example.) Something like this was requested multiple times, and I want it too.
* command: replace ROUND() with lrint()wm42015-12-261-2/+0
| | | | | lrint() pretty much does what ROUND() is supposed to do, but it's more precise.
* msg: remove redundant conditionwm42015-12-051-1/+1
| | | | Found by Coverity.
* video: pass through libavformat has_b_frames fieldwm42015-10-191-0/+1
| | | | | | | This fixes initial decoding of some samples. See #1341. According to Libav devs, this should be considered a libavcodec bug, but as it's hard to fix, here we go.
* msg: remove the useless trailing comment from stats dumpingwm42015-10-141-4/+2
| | | | | The origin of the stats line was added as a comment (starting with '#'). It was useless and just blowing up file sizes.
* video: make container vs. bitstream aspect ratio configurablewm42015-08-301-1/+0
| | | | | | Utterly idiotic bullshit. Fixes #2259.
* av_common: remove deprecated API usagewm42015-08-071-2/+0
| | | | | | | | | | As the removed comment says, not copying this field may cause problems on older libav* releases. See also commit 5f7de399. Remove this, as newer FFmpeg releases are available. As of this commit, use of mpv with FFmpeg 2.5.x and below, or Libav 11 and below is not recommended, and may lead to random video decoding issues. (Although the failure cases are apparently somewhat obscure.)
* player: warn against using HLS URLs with --playlistwm42015-08-041-0/+4
| | | | | | | | | That just makes no sense, but seems to be a somewhat common user error. The detection is not perfect. It's conceivable that EXT-X-... headers are used in normal m3u playlists. After all, HLS playlists are by definition a compatible extension to m3u playlists, as stupid as it sounds.
* av_log: remove dumb shitwm42015-07-181-24/+1
| | | | | | | It's the user's fault if he/she/it does something that is not recommended. Fixes #2110.
* player: parse and expose m3u playlist titleswm42015-07-101-0/+2
| | | | Requested. Closes #2100.
* av_log: print FFmpeg versionwm42015-07-031-0/+4
| | | | | The individual library versionsd are pretty useless. This will actually tell us at least the git hash or git tag of the FFmpeg build.
* client API: allow using msg-level option for log messageswm42015-06-202-11/+13
| | | | | | | | | | | | | | | | Client API users can enable log output with mpv_request_log_messages(). But you can enable only a single log level. This is normally enough, but the --msg-level option (which controls the terminal log level) provides more flexibility. Due to internal complexity, it would be hard to provide the same flexibility for each client API handle. But there's a simple way to achieve basically the same thing: add an option that sends log messages to the API handle, which would also be printed to the terminal as by --msg-level. The only change is that we don't disable this logic if the terminal is disabled. Instead we check for this before the message is output, which in theory can lower performance if messages are being spammed. It could be handled with some more effort, but the gain would be negligible.
* av_log: skip prefix if unknownwm42015-06-201-2/+3
| | | | | | | | This happens with av_log(NULL, ...) calls. Drop the "?: " fallback prefix, because it was confusing. (Of course FFmpeg should not do this at all, but it's a very long way to making the FFmpeg log callback sane.)
* Various spelling fixesMarcin Kurczewski2015-06-181-1/+1
| | | | Signed-off-by: wm4 <wm4@nowhere>
* av_log: set default av_log callback on exitwm42015-06-171-0/+1
| | | | | | | | | | | | This is slightly "dangerous", because it could overwrite a log callback another library has set, after we've set our own callback. But it's probably still slightly better than leaving our own callback, which will run the fallback code if no mpv instance is set. (Multiple mpv instances sharing the same global state will safely avoid overwriting each other's log callback.) Note that we can't do much better, because the global state in FFmpeg is obviously insane.
* audio: add --audio-spdif as new method for enabling passthroughwm42015-06-052-0/+29
| | | | | | | | | | | | | This provides a new method for enabling spdif passthrough. The old method via --ad (--ad=spdif:ac3 etc.) is deprecated. The deprecated method will probably stop working at some point. This also supports PCM fallback. One caveat is that it will lose at least 1 audio packet in doing so. (I don't care enough to prevent this.) (This is named after the old S/PDIF connector, because it uses the same underlying technology as far as the higher level protoco is concerned. Also, the user should be renamed that passthrough is backwards.)
* path: make mp_path_join accept normal C stringswm42015-05-091-1/+1
| | | | | Instead of bstr. Most callers of this function do not need bstr. The bstr version of this function is now mp_path_join_bstr().
* x11: query ICC profile based on center of windowNiklas Haas2015-04-292-0/+7
| | | | | | | | | | Right now, the default behavior is to pick the numerically lowest screen ID that overlaps the window in any way - but this means that mpv will decide to pick an ICC profile in a pretty arbitrary way even if the window only overlaps another screen by a single pixel. The new behavior is to query it based on the center of the window instead.
* options: remove unneeded hack from command line parserwm42015-04-232-11/+1
| | | | | | | | | | | | | | | This was traditionally needed to silence terminal output from errors during command line parsing preparsing. Preparsing is done so that options controlling the terminal and config files are parsed and applied first, with a second command line parsing pass applying all other options, _and_ printing error messages for the preparsed ones. But the hack silencing log output during the preparse pass is actually not needed anymore, since the terminal is enabled only after preparsing is finished. update_logging() in main.c does this. So as long as update_logging() is called before m_config_preparse_command_line(), this will work.
* Update license headersMarcin Kurczewski2015-04-1310-46/+38
| | | | Signed-off-by: wm4 <wm4@nowhere>
* vd_lavc: request 1 more threads than CPU coreswm42015-03-051-0/+2
| | | | | | | | | | This duplicates the logic which FFmpeg's libavcodec uses. The effects are unknown, though it's somewhat clear that a single thread doesn't necessarily saturate a single CPU. (Eventually we should just let FFmpeg auto-init the thread count, but for now I prefer it this way, so e.g. verbose mode will print the thread count.)
* player: refine rar:// playlist-safety handlingwm42015-03-021-0/+2
| | | | | | | | | | | | 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.
* msg: use relaxed atomics for log level testwm42015-03-021-1/+4
| | | | | | This should be sufficient. If stdatomic.h is not available, we make no difference.
* demux: add a demux_open_url() functionwm42015-02-201-10/+7
| | | | | Often stream and a demuxer are opened at the same time. Provide a function for this and replace most of its uses.
* demux: change demux_open() signaturewm42015-02-201-1/+2
| | | | Fold the relatively obscure force_format parameter into demuxer_params.
* player: drop explicit exit() callswm42015-02-121-2/+2
| | | | | | | | | The code in main.c calls exit() explicitly, but the code is actually easier to follow by simply exiting from main() instead. The exit() call in av_log.c happens only on severely broken builds, so replace it with abort(). (Shuts up rpmlint warnings.)
* options: change --msg-level optionwm42015-02-062-34/+17
| | | | | | | | | | | | | | Make it accept "," as separator, instead of only ":". Do this by using the key-value-list parser. Before this, the option was stored as a string, with the option parser verifying that the option value as correct. Now it's stored pre-parsed, although the log levels still require separate verification and parsing-on-use to some degree (which is why the msg-level option type doesn't go away). Because the internal type changes, the client API "native" type also changes. This could be prevented with some more effort, but I don't think it's worth it - if MPV_FORMAT_STRING is used, it still works the same, just with a different separator on read accesses.
* av_common: add comment about using now-deprecated libavcodec fieldwm42015-01-301-1/+2
| | | | | | | | | | FFmpeg and Libav have the stupid practice of replacing and deprecating API symbols on the same day. So with FFmpeg git, this is useless and will print a compile time warning, while it's required with all stable releases, and might lead to decoding errors with xvid/avi (apparently). Add a comment before someone writes a patch and I have to explain it all over again.
* msg: add --log-file optionwm42015-01-261-0/+22
| | | | | | | | | This allows getting the log at all with --no-terminal and without having to retrieve log messages manually with the client API. The log level is hardcoded to -v. A higher log level would lead to too much log output (huge file sizes and latency issues due to waiting on the disk), and isn't too useful in general anyway. For debugging, the terminal can be used instead.
* video: remove vfcap.hwm42015-01-211-3/+2
| | | | | | | | | | | | | | | | | And remove all uses of the VFCAP_CSP_SUPPORTED* constants. This is supposed to reduce conversions if many filters are used (with many incompatible pixel formats), and also for preferring the VO's natively supported pixel formats (as opposed to conversion). This is worthless by now. Not only do the main VOs not use software conversion, but also the way vf_lavfi and libavfilter work mostly break the way the old MPlayer mechanism worked. Other important filters like vf_vapoursynth do not support "proper" format negotation either. Part of this was already removed with the vf_scale cleanup from today. While I'm touching every single VO, also fix the query_format argument (it's not a FourCC anymore).
* player: don't set tag strings to NULLwm42015-01-121-3/+3
| | | | | | | | | | | | | bstr is a bounded string type, consisting of a pointer and a length value. If the length is 0, the pointer can be NULL. This is somewhat logical due to how this abstraction works, but it can leak when converting to C strings. talloc_strndup() returns NULL instead of "" in this case, which broke some other code. Use bstrto0() instead, which is the "proper" function to convert bstr to char*. Fixes #1462.
* player: change --display-tags behaviorwm42015-01-121-7/+16
| | | | | | | | | | | | | | | | | | Remove the "all" special-behavior, and instead interpret trailing "*" characters. --display-tags=all is replaced by --display-tags=* as a special-case of the new behavior. See #1404. Note that the most straight-forward value for matchlen in the normal case would be INT_MAX, because it should be using the entire string. I used keylen+1 instead, because glibc seems to handle this case incorrectly: snprintf(buf, sizeof(buf), "%.*s", INT_MAX, "hello"); The result is empty, instead of just containing the string argument. This might be a glibc bug; it works with other libcs (even MinGW-w64).
* player: use libavutil API to get number of CPUswm42015-01-051-3/+2
| | | | | | | | | | | Our own code was introduced when FFmpeg didn't provide this API (or maybe didn't even have a way to determine the CPU count). But now, av_cpu_count() is available for all FFmpeg/Libav versions we support, and there's no reason to have our own code. libavutil's code seems to be slightly more sophisticated than our's, and it's possible that the detected CPU count is different on some platforms after this change.
* player: print used number of threads in verbose modewm42015-01-052-4/+6
| | | | Also, don't use av_log() for mpv output.
* command: make the "run" command work on Windows toowm42015-01-012-3/+5
| | | | | | | | | Do so by using mp_subprocess(). Although this uses completely different code on Unix too, you shouldn't notice a difference. A less ncie thing is that this reserves an entire thread while the command is running (which wastes some memory for stack, at least). But this is probably still the simplest way, and the fork() trick is apparently not implementable with posix_subprocess().
* player: filter tags, add --display-tags optionwm42014-12-292-0/+20
| | | | | | | | This attempts to increase user-friendliness by excluding useless tags. It should be especially helpful with mp4 files, because the FFmpeg mp4 demuxer adds tons of completely useless information to the metadata. Fixes #1403.
* Do not call strerror()wm42014-11-262-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | ...because everything is terrible. strerror() is not documented as having to be thread-safe by POSIX and C11. (Which is pretty much bullshit, because both mandate threads and some form of thread-local storage - so there's no excuse why implementation couldn't implement this in a thread-safe way. Especially with C11 this is ridiculous, because there is no way to use threads and convert error numbers to strings at the same time!) Since we heavily use threads now, we should avoid unsafe functions like strerror(). strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and gives the function different semantics than the POSIX one. It's a bit of work to convince this piece of shit to expose the POSIX standard function, and not the messed up GNU one. strerror_l() is also in POSIX, but only since the 2008 standard, and thus is not widespread. The solution is using avlibc (libavutil, by its official name), which handles the unportable details for us, mostly. We avoid some pain.
* Silence some Coverity warningswm42014-11-211-0/+1
| | | | None of this really matters.
* common: fix version variable declarationswm42014-11-022-2/+3
| | | | This was stupid.
* common: fix \x-style escapingshdown2014-10-161-1/+1
| | | | This was rejecting correct escapes and accepting incorrect ones.
* Add some missing "const"swm42014-10-102-2/+2
| | | | | | | The one in msg.c was mistakenly removed with commit e99a37f6. I didn't actually test the change in ao_sndio.c (but obviously "ap" shouldn't be static).

* msg: fix unwanted blank lineswm42014-10-081-1/+3
| | | | Was broken in a commit earlier this day.
* client API: introduce numeric log levelswm42014-10-082-0/+15
| | | | | | | | | | | | | | | | Maybe using strings for log levels was a mistake (too broad and too impractical), so I'm adding numeric log level at least for the receiver side. This makes it easier to map mpv log levels to other logging systems. I'm still too stingy to add a function to set the log level by a numeric value, though. The numeric values are not directly mapped to the internal mpv values, because then almost every file in mpv would have to include the client API header. Coalesce this into API version 1.6, since 1.6 was bumped just yesterday.
* msg, client API: buffer partial lineswm42014-10-081-61/+73
| | | | | | | | | | | | | | | The API could return partial lines, meaning the message could stop in the middle of a line, and the next message would have the rest of it (or just the next part of it). This was a pain for the user, so do the nasty task of buffering the lines ourselves. Now only complete lines are sent. To make things even easier for the API user, don't put multiple lines into a single event, but split them. The terminal output code needed something similar (inserting a prefix header on start of each line). To avoid code duplication, this commit refactors the terminal output so that lines are split in a single place.
* msg, client API: never send the status line as log messagewm42014-10-081-1/+1
| | | | | | | | | | | | | The status line is a bit special; for example it uses special control codes by design and is not terminated with a newline character in order to update it on the terminal without scrolling. It's not helpful for client API users either, and would require special-casing them (emulating aspects of a terminal?). Also, the status line code is explicitly disabled on osd.c unless the --terminal option is enabled, so there was no good way to even enable the status line for the API. Just pretend that the status line does not exist as far as the client API is concerned. It won't be sent as MPV_EVENT_LOG_MESSAGE.
* msg: set an explicit overflow messagewm42014-10-081-1/+1
| | | | | | | | So client API users don't have to worry about this specifically. Also document the overflow case. (Not sure if we really need to do this; maybe it'd be better not to, since this just adds more noise to the docs.)
* stream: redo playback abort handlingwm42014-09-131-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mechanism originates from MPlayer's way of dealing with blocking network, but it's still useful. On opening and closing, mpv waits for network synchronously, and also some obscure commands and use-cases can lead to such blocking. In these situations, the stream is asynchronously forced to stop by "interrupting" it. The old design interrupting I/O was a bit broken: polling with a callback, instead of actively interrupting it. Change the direction of this. There is no callback anymore, and the player calls mp_cancel_trigger() to force the stream to return. libavformat (via stream_lavf.c) has the old broken design, and fixing it would require fixing libavformat, which won't happen so quickly. So we have to keep that part. But everything above the stream layer is prepared for a better design, and more sophisticated methods than mp_cancel_test() could be easily introduced. There's still one problem: commands are still run in the central playback loop, which we assume can block on I/O in the worst case. That's not a problem yet, because we simply mark some commands as being able to stop playback of the current file ("quit" etc.), so input.c could abort playback as soon as such a command is queued. But there are also comm
