It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

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 596e5d47, 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:

Otherwise ffmpeg -formats claims that we only support demuxing of that format. To keep compatibility the struct could be duplicated instead, but this seems almost like overkill for such a rare format. Signed-off-by:

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.

Also remove some pointless NULL/0 assigments. C++ code must be left as it is because named struct initializers are not supported by C++ standard.

It's supposed to be called only from (de)muxers.

Use it instead of url_is_streamed and AVIOContext.is_streamed.

VC1 test container always uses time-base 1 ms, so we must convert from whatever time-base the application gave us to that, otherwise the video will play at ridiculous speeds. It would be possible to signal that a container supports only one time-base and have code in a layer above do the conversion, but for a single format this seems over-engineered.

This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts. (cherry picked from commit c6610a21)
