* 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.
* mpegtsenc: add flag to embed an AC-3 ES the DVB wayStefan Pöschel2015-12-14
| | | | | | | | | | | | | So far an AC-3 elementary stream is refered to in the PMT according to System A (ATSC). However System B (DVB) has a different way to signal an AC-3 ES within the PMT. This different way can be enabled by a new flag. The flag is more generally named 'system_b' as there are further differences between ATSC and DVB (e.g. the signalling of E-AC-3) which should then also be covered by it in the future.

* lavf: switch to AVStream.time_base as the hint for the muxer timebaseAnton Khirnov2014-06-18
| | | | | | | | | | | | Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).

* mpegts: adjustable minimum PES payloadJindřich Makovička2011-12-28
| | | | | | | | | | | | With the current default PES packet size, and very small audio bitrates, audio packet duration gets too long. For players, which wait for a whole audio packet (or more) it takes a very long time to start playing sound. For 24kbps audio, one PES packet is about 1 second long. On Motorola STBs, we observe about 3 second delay before the playback starts with the default setting. Signed-off-by: Anton Khirnov <anton@khirnov.net>
