* avformat/flvenc: Avoid unnecessary seekAndreas Rheinhardt2020-01-17
| | | | | | | | | | | | | | When shifting the already written data in order to write the keyframe index, the flv muxer would first store the pre-shift size, then calculate how big the index will be eventually, then perform some seeks to update some size fields, then seek back to the end of the file to get the new position, followed by a seek to the position where writing will really start. Seeking back to the (already known) end position (that is actually used to perform this seek) to get the end position is of course unnecessary. It has been removed.

* avformat/flvenc: Forward errors from allocating keyframe indexAndreas Rheinhardt2019-12-26
| | | | | | | | | | | While the function adding a new element to the keyframe index checked the allocation, the caller didn't check the return value. This has been changed. To do so, the return value has been changed to an ordinary ret instead of pb->error. This doesn't pose a problem, as write_packet() in mux.c already checks for write errors (since 9ad1e0c1).

| * 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.

* | avformat/flvenc: copyts in FLV muxerIvan2016-01-26
| | | | | | | | | | | | | | | | | | The purpose of this patch is to preserve timestamps when using ffmpeg for publishing RTMP streams, e.g. ffmpeg -i rtmp://source/stream -f flv rtmp://target/stream. There is a setting "copyts" for that purpose. Unfortunately it doesn't work with FLV muxer because it has its own timestamp correction which makes global setting "copyts" ineffective. This patch removes timestamp correction in FLV muxer. This means FLV will rely on ffmpeg timestamp correction which makes it possible to use copyts.
