* 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.

| | | | | | | The AVSC_API changes in the new headers mean that the 2.6 alphas are just as incompatible as 2.5 is. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* avisynth: Fix detection of AviSynth 2.5Stephen Hutchinson2015-04-14
| | | | | | | | | In order to safely exit when the user tries to use AviSynth 2.5, the continue_on_fail value for 2.6's functions need to be set to 1. Otherwise, the library loader fails before the 'upgrade to 2.6' log message appears. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* avisynth: Fix compilation against current 2.6 header(s).Stephen Hutchinson2015-03-24
| | | | | | | | | AviSynth 2.6 (and by extension, AviSynth+) moves these functions into AVSC_API. This requires both adjusting their normal use, and for AvxSynth, adjusting the position/use of the USING_AVISYNTH ifdefs. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* avformat: AviSynth demuxer rewrited s2013-12-08
| | | | | | | | | | | | | | | | | | | | Directly loads AviSynth through LoadLibrary instead of relying on Video for Windows, and supports using AvxSynth (via dlopen) to open scripts on Linux and OS X. Error messages from AviSynth/AvxSynth are now reported through av_log and exit, rather than the traditional behavior of generating an error video that the user would need to watch to diagnose. The main rewrite was authored by d s <avxsynth.testing@gmail.com> from the AvxSynth team, with additional contributions by Oka Motofumi <chikuzen.mo@gmail.com> Stephen Hutchinson <qyot27@gmail.com> Diego Biurrun <diego@biurrun.de> Anton Khirnov <anton@khirnov.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavf: deprecate r_frame_rate.Anton Khirnov2012-07-29
| | | | | | | | | | | | | | | | | | | | According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.
* avisynth: Make sure the filename passed to avisynth is in the right code pageOka Motofumi2012-05-31
| | | | | | | | avisynth is a non-unicode application and cannot accept UTF-8 characters. Therefore, the input filename should be converted to the correct code page that it expects. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: replace av_new_stream->avformat_new_stream part II.Anton Khirnov2011-10-19
| | | | | | | | Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.
