* demux: minor simplificationwm42014-07-061-2/+2
| | | | Oops, should have been part of commit 37085788.
* demux: minor simplification to internal APIwm42014-07-051-1/+1
| | | | Also some other unrelated minor changes.
* dvd: flush buffers properly on seekwm42014-07-051-3/+4
| | | | | | | | | | | Suggested by tholin on github issue #882. This is not entirely clean, but the fields we're accessing might be considered internal to libavformat. On the other hand, existence of the fields is guaranteed by the ABI, and nothing in the libavformat doxygen suggestes they're not allowed to be accessed. CC: @mpv-player/stable
* dvd, bluray, cdda: add demux_disc containing all related hackswm42014-07-051-14/+2
| | | | | | | | | | | | DVD and Bluray (and to some extent cdda) require awful hacks all over the codebase to make them work. The main reason is that they act like container, but are entirely implemented on the stream layer. The raw mpeg data resulting from these streams must be "extended" with the container-like metadata transported via STREAM_CTRLs. The result were hacks all over demux.c and some higher-level parts. Add a "disc" pseudo-demuxer, and move all these hacks and special-cases to it.
* demux: make start time a simple fieldwm42014-07-051-5/+7
| | | | Simpler, especially for later changes.
* demux, stream: change metadata notificationwm42014-07-051-0/+1
| | | | | | | | | | | | (Again.) This time, we simply make it event-based, as it should be. This is done for both demuxer metadata and stream metadata. For some ogg-over-icy streams, 2 updates are reported on stream start. This is because libavformat reports an update right on start, while including the same info in the "static" metadata. I don't know if that's a bug or a feature.
* demux: make replaygain per-trackwm42014-07-051-3/+3
| | | | | | It's unlikely that files with multiple audio tracks and with replaygain actually happen, but this change might help avoid minor corner cases with later changes.
* demux_lavf: for now, ignore the new libavformat image demuxerswm42014-07-051-0/+3
| | | | | | | | | | | | Recently, libavformat added demuxers to open image files like normal demuxers. This is a good thing, but for now they interfere with the operation of demux_mf. Add them to the blacklist until there is a proper solution. (The list doesn't contain _all_ recognized image formats, just those that might interfere with demux_mf.) CC: @mpv-player/stable
* demux_lavf: support OTF fonts in Matroskawm42014-07-051-3/+10
| | | | Apparently it's FFmpeg only.
* demux_lavf: don't dump transport stream programswm42014-07-051-13/+0
| | | | Probably useless.
* demux_lavf: cleanup debug outputwm42014-07-051-19/+10
| | | | Remove unnecessary prefix, remove some messages.
* demux_lavf: fix read_seek return valuewm42014-07-051-3/+1
| | | | | | | This returned a stream error value directly to libavformat, which can't make sense. For example STREAM_ERROR (0) means success in libavformat error codes. (The meaning of the libavformat read_seek return value is underdocumented too.)
* demux_lavf: remove unused symbolwm42014-06-231-2/+0
|
* options: turn --idx, --forceidx into --indexwm42014-06-131-1/+1
| | | | | | | | | | | | Also clarify the semantics. It seems --idx didn't do anything. Possibly it used to change how the now removed legacy demuxers like demux_avi used to behave. Or maybe it was accidental. --forceidx basically becomes --index=force. It's possible that new index modes will be added in the future, so I'm keeping it extensible, instead of e.g. creating --force-index.
* demux_lavf: make option struct localwm42014-06-111-16/+34
| | | | Similar to previous commits.
* Add more constwm42014-06-111-3/+3
| | | | | | | While I'm not very fond of "const", it's important for declarations (it decides whether a symbol is emitted in a read-only or read/write section). Fix all these cases, so we have writeable global data only when we really need.
* demux_lavf: support new rotation metadata APIwm42014-06-011-1/+11

* command: improve video-bitrate propertyAndrey Morozov2014-06-011-0/+3
| | | | | | Signed-off-by: wm4 <wm4@nowhere> Includes some cosmetic changes over the original PR.
* audio: rename i_bps to 'bitrate' to avoid confusionMarcoen Hirschberg2014-05-281-2/+2
| | | | Since i_bps now contains bits/sec, rename it to reflect this change.
* audio: change values from bytes-per-second to bits-per-secondMarcoen Hirschberg2014-05-281-2/+2
| | | | | | | The i_bps members of the sh_audio and dev_video structs are mostly used for displaying the average audio and video bitrates. Keeping them in bits-per-second avoids truncating them to bytes-per-second and changing them back lateron.
* stream: don't use end_poswm42014-05-241-11/+14
| | | | | | | | | | | | | | | | | | | Stop using it in most places, and prefer STREAM_CTRL_GET_SIZE. The advantage is that always the correct size will be used. There can be no doubt anymore whether the end_pos value is outdated (as it happens often with files that are being downloaded). Some streams still use end_pos. They don't change size, and it's easier to emulate STREAM_CTRL_GET_SIZE using end_pos, instead of adding a STREAM_CTRL_GET_SIZE implementation to these streams. Make sure int64_t is always used for STREAM_CTRL_GET_SIZE (it was uint64_t before). Remove the seek flags mess, and replace them with a seekable flag. Every stream must set it consistently now, and an assertion in stream.c checks this. Don't distinguish between streams that can only be forward or backwards seeked, since we have no such stream types.
* stream: kill start_pos, remove --sb optionwm42014-05-241-4/+4
| | | | | | | | | | | | | | | | | | | | stream.start_pos was needed for optical media only, and (apparently) not for very good reasons. Just get rid of it. For stream_dvd, we don't need to do anything. Byte seeking was already removed from it earlier. For stream_cdda and stream_vcd, emulate the start_pos by offsetting the stream pos as seen by the rest of mpv. The bits in discnav.c and loadfile.c were for dealing with the code seeking back to the start in demux.c. Handle this differently by assuming the demuxer is always initialized with the stream at start position, and instead seek back if initializing the demuxer fails. Remove the --sb option, which worked by modifying stream.start_pos. If someone really wants this option, it could be added back by creating a "slice" stream (actually ffmpeg already has such a thing).
* demux_lavf: one more hack for mp3 from networkwm42014-05-041-1/+1
| | | | | | | | | | | | | | mp3 has a hack lowering the probescore for format detection. This is because detecting mp3s is hard due to their nature, and the fact that ID3v2 tags are sometimes several megabytes big. When playing mp3 from network, the mime-type is usually set, and that matches the format hack entry meant for webradios, overriding the normal mp3 entry. This can lead to network mp3s not being detected. Lower the network case to the same probescore as on-disk mp3s. The difference is that for network mp3s, we don't load the full probe-buffer, and we lower the amount of audio the demuxer will read to collect data on opening (0.5 seconds instead of typically 5 seconds).
* demux: export video rotation parameterwm42014-04-211-0/+8
| | | | | Now the rotation hint is propagated everywhere. It just isn't used anywhere yet.
* mp_tags: move generic mp_tags stuff into its own .c/.h files in common/Kevin Mitchell2014-04-131-11/+5
| | | | | | rename add_metadata to the more genera/descriptive mp_tags_copy_items_from_av_dictionary Signed-off-by: wm4 <wm4@nowhere>
* stream_dvd, cache: hack seeking with --cache + dvd:// back into workingwm42014-04-091-0/+2
| | | | | | | | | | | | | | | | | | | This was broken at some unknown point (even before the recent cache changes). There are several problems: - stream_dvd returning a random stream position, confusing the cache layer (cached data and stream data lost their 1:1 corrospondence by position) - this also confused the mechanism added with commit a9671524, which basically triggered random seeking (although this was not the only problem) - demux_lavf requesting seeks in the stream layer, which resulted in seeks in the cache or the real stream Fix this by completely removing byte-based seeking from stream_dvd. This already works fine for stream_dvdnav and stream_bluray. Now all these streams do time-based seeks, and pretend to be infinite streams of data, and the rest of the player simply doesn't care about the stream byte positions.

* demux_lavf: fix typo in commentwm42014-03-041-1/+1
| | | | Pushed too early...
* sub: use new FFmpeg API to check MicroDVD FPSwm42014-03-041-5/+13
| | | | | | Before this, it wasn't possible to distinguish MicroDVD subtitles without FPS header, and subtitles with FPS header equal to FFmpeg's fallback FPS.
* sub: handle vobsub-in-mp4wm42014-02-131-0/+2
| | | | | | | | | | | The mplayer decoder (spudec.c) actually handled this. There was explicit code for binary palettes (16 32 bit values), and the subtitle resolution was handled by video resolution coincidentally matching the subtitle resolution. Whoever puts vobsub into mp4 should be punished. Fixes the sample gundam_sample.mp4, closes github issue #547.
* demux_lavf: work around idiotic libavutil API printing a warningwm42014-02-081-1/+5
| | | | | | | | | | Trying to set a non-existent flag (like +keepside on Libav) causes libavutil print an incomprehensible warning (something about eval; probably the overengineered libavutil option parser tripping over the '+' normally used for flags, and trying to interpret it as formula). There's apparently no easy way to check for the existence of a flag, so add some more ifdeffery to shut it up.
* demux_lavf: do metadata-from-packet update before possibly discarding itwm42014-02-061-2/+1
| | | | | | | | | | | | There is some logic to discard packets from streams that are not selected. Run the metadata update code before this, just to make 100% sure that no metadata updates can be lost when streams are deselected. (I'm not sure why this logic would be needed, since both libavformat and the generic demuxer code do this already. But a quick test shows that av_read_frame() can return a packet from a stream even if the stream has AVStream.discard set to AVDISCARD_ALL. This happened after stream switching. Maybe libavformat doesn't discard already queued packets.)
* demux_lavf: don't check for error when setting "keepside" flagwm42014-02-061-4/+1
| | | | | This flag doesn't exist on Libav (because they never do this insane packet merging stuff), so this would print unnecessary warnings there.
* demux: fill metadata directly, instead of using wrapper functionswm42014-02-061-12/+8
| | | | | | Get rid of demux_info_add[_bstr] and demuxer_add_chapter_info. Make demuxer_add_chapter_info return the chapter index for convenience.
* demux_lavf: clear metadata on update, instead of merging itwm42014-02-061-0/+1
| | | | | Assume a metadata update is a full update. Clear the previous metadata, so that tags which existed only in the previous metadata are removed.
* demux_lavf: get updated metadata from a packet if availableBen Boeckel2014-02-061-0/+25
| | | | The side_data type is brand new in ffmpeg.
* demux_lavf: fix crash with empty fileswm42014-01-311-1/+1
| | | | | | | | | | This used to work; I'm not sure when or why it regressed. When setting AVProbeData.filename to NULL, libavformat will crash in rtp_probe() by unconditionally accessing the string. We used to set the filename to NULL to prevent probing by file extension when we don't deem it as necessary. Using an empty string also works for this purpose.
* demux_lavf: add hack to workaround too unreliable mp3 detectionwm42014-01-251-0/+2
| | | | | | | | | | | This generally affects mp3 files that don't have any (or many) mp3 frames in the first 2 MB. 2 MB is the maximum probe size, and libavformat returns a low probescore even if we give it the full 2 MB. Trying to probe a larger buffer (or even the full file) doesn't work for mysterious reasons. The workaround consists in accepting a very weak probescore if the format is detected as mp3 and we probed already 2 MB.
* demux_lavf: refactor format probing hackwm42014-01-251-26/+24
| | | | | | Restructure it a bit, so we can use the format hack list even if no mime type applies. Shouldn't change anything functionally yet. Preparation for the next commit.
* demux_lavf: add hack for MicroDVD for assuming frame based timingwm42014-01-101-0/+6
| | | | | | | | | | | MicroDVD files _can_ contain real timestamps instead of frame timestamps if they declare a FPS. But this seems to be rare, so ignore that if the FPS happens to match with the libavformat microdvd parser's default FPS. This might actually break files that declare 23.976 FPS, but the video file is not 23.976 FPS, but the chance that this happens is probably very low, and the commit fixes the more common breakage with 25 FPS video.
* demux_lavf: fix minor memory leakwm42014-01-071-1/+1

* demux: mp_msg conversionswm42013-12-211-33/+26
| | | | | | | 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.
* Split mpvcore/ into common/, misc/, bstr/wm42013-12-171-4/+4
|
* Move options/config related files from mpvcore/ to options/wm42013-12-171-2/+2
| | | | | | | | | Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.
* stream: add function for dropping the bufferwm42013-12-141-0/+1
| | | | | And use it in demux_lavf.c. It looks like otherwise, some data might be left over, depending on how the hell av_seek_frame() behaves.
* demux_lavf: fix timebase confusionwm42013-12-121-7/+7
| | | | | This set last_pts to bogus values, which is used for relative seeks. The player usually uses absolute seeks, so this didn't matter much.
* demux_lavf: remove unnecessary seek on initializationwm42013-12-121-2/+0
| | | | This is not needed, and actually completely incorrect.
* video: add insane hack to work around FFmpeg/Libav insanitywm42013-11-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So, FFmpeg/Libav requires us to figure out video timestamps ourselves (see last 10 commits or so), but the methods it provides for this aren't even sufficient. In particular, everything that uses AVI-style DTS (avi, vfw-muxed mkv, possibly mpeg4-in-ogm) with a codec that has an internal frame delay is broken. In this case, libavcodec will shift the packet- to-image correspondence by the codec delay, meaning that with a delay=1, the first AVFrame.pkt_dts is not 0, but that of the second packet. All timestamps will appear shifted. The start time (e.g. the time displayed when doing "mpv file.avi --pause") will not be exactly 0. (According to Libav developers, this is how it's supposed to work; just that the first DTS values are normally negative with formats that use DTS "properly". Who cares if it doesn't work at all with very common video formats? There's no indication that they'll fix this soon, either. An elegant workaround is missing too.) Add a hack to re-enable the old PTS code for AVI and vfw-muxed MKV. Since these timestamps are not reorderd, we wouldn't need to sort them, but it's less code this way (and possibly more robust, should a demuxer unexpectedly output PTS). The original intention of all the timestamp changes recently was actually to get rid of demuxer-specific hacks and the old timestamp sorting code, but it looks like this didn't work out. Yet another case where trying to replace native MPlayer functionality with FFmpeg/Libav led to disadvantages and bugs. (Note that the old PTS sorting code doesn't and can't handle frame dropping correctly, though.) Bug reports: https://trac.ffmpeg.org/ticket/3178 https://bugzilla.libav.org/show_bug.cgi?id=600
* demux_lavf: disable genpts by default, remove the builtin genpts hackwm42013-11-251-86/+9
| | | | | | | | | This was needed to determine PTS from DTS, but the previous commits make it unnecessary. The builtin genpts hack was used for DVD, because libavformat's genpts essentially went amok on DVD timestamp resets. See commit 65d87091 for details.
* demux: export dts from demux_lavf, use it for aviwm42013-11-251-10/+11
| | | | | | | | | Having the DTS directly can be useful for restoring PTS values. The avi file format doesn't actually store PTS values, just DTS. An older hack explicitly exported the DTS as PTS (ignoring the [I assume] genpts generated non-sense PTS), which is not necessary anymore due to this change.
* demux: remove gsh field from sh_audio/sh_video/sh_subwm42013-11-231-2/+2
| | | | | | | | | 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: simplify handling of filepos fieldwm42013-11-161-3/+1
| | | | | | | | | | | | demuxer->filepos contains the byte offset of the last read packet. This is so that the player can estimate the current playback position, if no proper timestamps are available. Simplify it to use demux_packet->pos in the generic demuxer code, instead of bothering every demuxer implementation about it. (Note that this is still a bit incorrect: it relfects the position of the last packet read by the demuxer, not that returned to the user. But that was already broken, and is not that trivial to fix.)
* demux_lavf: remove broken and commented byte based seekswm42013-11-161-40/+0
| | | | | | | | | | | | | This was originally added for better seeking where libavformat's seek function won't work well: files with timestamp resets. In these cases, the code tried to calculate an average bitrate, and then do byte based seeks by multiplying the seek target time with the bitrate. Apparently this was unreliable enough that the code was just commented (and other parts became inactive). Get rid of it. Note that the player still does byte based seeks in these cases when doing percent-seeks.
* demux: make determining seek capability genericwm42013-11-031-5/+6
| | | | | | | | | | | | | | | | 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 fieldswm42013-11-031-6/+6
| | | | | | | 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.
* Enable -Wshadowwm42013-11-011-1/+1
| | | | | | | | | This one really did bite me hard (see previous commit), so enable it by default. Fix some cases of shadowing throughout the codebase. None of these change behavior, and all of these were correct code, and just tripped up the warning.
* talloc: change talloc destructor signaturewm42013-10-131-2/+1
| | | | | | | | | | | | | Change talloc destructor so that they can never signal failure, and don't return a status code. This makes our talloc copy even more incompatible to upstream talloc, but on the other hand this is preparation for getting rid of talloc entirely. (The talloc replacement in the next commit won't allow the talloc_free equivalent to fail, and the destructor return value would be useless. But I don't want to change any mpv code either; the idea is that the talloc replacement commit can be reverted for some time in order to test whether the talloc replacement introduced a regression.)
* network: fix rtsp playbackwm42013-09-221-1/+22
| | | | | | | | | | | | | | By default, libavformat uses UDP for rtsp playback. This doesn't work very well. Apparently the reason is that the buffer sizes libavformat chooses for UDP are way too small, and switching to TCP gets rid of this issue entirely (thanks go to Reimar Döffinger for figuring this out). In theory, you can set buffer sizes as libavformat options, but that doesn't seem to help. Add an option to select the rtsp transport, and make TCP the default. Al
