* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat: move AVStream.{parser,need_parsing} to AVStreamInternalJames Almer2021-05-07
| | | | | | | Those are private fields, no reason to have them exposed in a public header. Signed-off-by: James Almer <jamrial@gmail.com>

* avformat/s337m: Use and test Dolby-E-parserAndreas Rheinhardt2021-03-23
| | | | | | | | This makes av_read_frame() return packets with proper timestamps. As a result, seeking now works in combination with streamcopy. A FATE-test for this has been added. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat: Remove unnecessary av_packet_unref()Andreas Rheinhardt2020-02-10
| | | | | | | | | Since bae8844e the packet will always be unreferenced when a demuxer returns an error, so that a lot of calls to av_packet_unref() in lots of demuxers are now redundant and can be removed.

* avformat/s337m: Use base AVClass for av_log usageNicolas Gaullier2020-01-16
| | | | | | | | s337m_get_offset_and_codec does not make use of AVFormatContext: AVClass is enough for logging. Will facilitate further use from outside Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat/s337m: fix potentially undefined pointer arithmeticfoo862017-07-26
| | | | | Use integer position instead of pointer for loop variable. Also only skip header fields after header has been fully validated.
