2020-01-07avformat: remove avio_flush() calls from the end of write_packet functionsMarton Balint
Removing explicit avio_flush() calls helps us to buffer more data and avoid flushing the IO context too often which causes reduced IO throughput for non-streamed file output. The user can control flushing behaviour at the end of every packet using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used. Therefore this change should have no adverse effect on streaming, even if it is assumed that a new packet has a clean buffer so small seekbacks within the output buffer work even when the IO context is not seekable.

2016-02-23lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov
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.

2016-02-14avformat/img2enc: disable atomic file creation by defaultMarton Balint
Currently it is broken when explicitly using the file protocol, it uses an insecure temporary file name, and in commit b4431c80 disabling the option by default was already considered. Also it is not very consistent to have such an option for one particular muxer. Signed-off-by: Marton Balint <cus@passwd.hu>

2016-01-27avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis

2016-01-24lavf: allow custom IO for all filesAnton Khirnov
Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.
