* 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.

| | | | | | | | Since 596e5d4783, this is not necessary anymore. It also allows to actually disable the flushing, improving write performance (but possibly giving worse latency in real-time streaming). Signed-off-by: Martin Storsjö <martin@martin.st>

* spdifenc: fix byte order on big-endian systemsAnssi Hannula2011-02-13
| | | | | | | | | | | | | | | | | | | There is a check for HAVE_BIGENDIAN when outputting the IEC 61937 stream. On big-endian systems the payload data is not byteswapped, causing in effect the outputted payload data to be in a different byte order on big-endian than on little-endian systems. However, the IEC 61937 preamble (and the final odd byte if present) is always outputted in the same byte order. This means that on big-endian systems the headers have a different byte order than the payload, preventing useful use of the output. Fix that by outputting the data in a format suitable for sending to an audio device in S16LE format by default. Output as big-endian (S16BE) is added as an AVOption. This makes the muxer output the same on all archs by default. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
