| | | | | | | | | | Store the file duration in the same timebase it arrives (i.e. milliseconds) and only convert it to the file duration units (100ns) when it's actually written, thus simplifying some calculations. Also, store the duration as unsigned, since it cannot be negative. CC: libav-stable@libav.org Bug-ID: CVE-2016-2326
* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
* lavf: Replace the ASF demuxerAlexandra Hájková2015-06-28
| | | | | | | | | | | | | | | | | The old one is the result of the reverse engineering and guesswork. The new one has been written following the now-available specification. This work is part of Outreach Program for Women Summer 2014 activities for the Libav project. The fate references had to be changed because the old demuxer truncates the last frame in some cases, the new one handles it properly. The seek-test reference is changed because seeking works differently in the new demuxer. When seeking, the packet is not read from the stream directly, but it is rather constructed by the demuxer. That is why position is -1 now in the reference. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* asfenc: use codec descriptors instead of AVCodecs to write codec infoAnton Khirnov2014-05-01
| | | | | | | | Also, stop using AVCodecContext.codec_name as fallback, since it will be deprecated. Changes the result of the lavf-asf test (and its associated seektest), since 'msmpeg4v3' gets written instead of just 'msmpeg4'.
* asfenc: mux chapters in ASF files using an ASF "marker" sectionVladimir Pantelic2013-09-19
| | | | | | | | ASF markers only have a start time, so we lose the chapter end times, but that is ASF for you Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | This reverts commit d1bec33b46091546c5b2e6815210e73f87abf413, it breaks FATE.

* lavf: flush the output AVIOContext in av_write_trailer().Anton Khirnov2012-09-15
| | | | | | | This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.
* dict: add av_dict_count()Mans Rullgard2012-08-10
| | | | | | | | This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>

* lavf: use conditional notation for default codec in muxer declarations.Ronald S. Bultje2012-07-22
| | | | | This removes the use of macro nesting in these code constructs, which makes it easier to parse in pre-processors.
* cosmetics: Align muxer/demuxer declarationsMartin Storsjö2012-04-06

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_headerJohn Brooks2011-10-14
| | | | | | | | | | | | | | The cbSize field should be included in all cases, even with PCM where its value is ignored. Fixes encoding PCM audio in Matroska for some players which insist on a full WAVEFORMATEX structure for A_MS/ACM audio. Since fate uses wav files for the audio test a larger number of tests has changed checksums or shifted positions due to the 2 byte longer wave header.
