* lavf: fix demuxing of FLAC files with id3v2 tagsLynne27 hours1-0/+1
| | | | | | | | | Due to the recent id3v2 refactor, FLAC was left out due to earlier code not checking for id3v2 presence on FLAC. Without the id3v2 data parsed, detection of FLAC and therefore demuxing fails. Fixes 9d037c54f209958d47ac376d2a9561608f98dfae

* avformat/movenc: add support for fragmented TTML muxingJan Ekström5 days3-14/+152
| | | | | | | | | | | | Attempts to base the fragmentation timing on other streams as most receivers expect media fragments to be more or less aligned. Currently does not support fragmentation on subtitle track only, as the subtitle packet queue timings would have to be checked in addition to the current fragmentation timing logic. Signed-off-by: Jan Ekström <[email protected]>
* avformat/flvenc: fix event_flags checkZhao Zhili6 days1-2/+2
| | | | | | AVFormatContext.event_flags is checked against AVSTREAM_EVENT_FLAG, which belongs to AVStream.event_flags. There is no real issue since these two flags have the same value.

* avformat/oggdec: Don't skip over data whose checksum is usedAndreas Rheinhardt6 days1-1/+1
| | | | | | | | | | | | | | | | | | The behavior of the ffio_*_checksum feature is not well defined when using avio_skip(). The code in oggdec.c relied on the skipped data (four bytes) to be checksummed, which is mostly true because short_seek_threshold is 32768 by default, so that avio_seek() will normally read data instead of calling the underlying seek function. Yet this has two problems: a) It relies on implementation details of avio_seek(). b) There is an exception, namely if the AVIO_FLAG_DIRECT is set. In this case the underlying seek function (if set) is always called and the data is skipped, leading to CRC errors. So don't skip the data. Signed-off-by: Andreas Rheinhardt <[email protected]>
* avformat/aviobuf: Keep checksum_ptr consistent in avio_seek()Andreas Rheinhardt6 days1-1/+1
| | | | | | | | | | | | Otherwise it might be > buf_ptr in which case ffio_get_checksum() could segfault (s->buf_ptr - s->checksum_ptr would be negative which would be converted to something very big when converted to unsigned for the update_checksum callback). Fixes ticket #11233. Reported-by: Du4t Signed-off-by: Andreas Rheinhardt <[email protected]>
* avformat/whip: enable RTCP NACK for whipJack Lau6 days1-0/+53
| | | | | | | | | | | | | | | | Refer to RFC 4585 4.2, Add SDP "a=rtcp-fb" so the peer can request rtx through sending NACKs. Add basic parsing for NACK packet. Decrypt into a newly allocated buffer (do not overwrite whip->buf) so multiple NACKs in a bundled packet can be parsed in a loop while keeping whip->buf available for sending rtx Broken or wrong NACk are logged and skipped.

* avformat/img2dec: do not use av_get_frame_filename result buffer if the call ↵Marton Balint2025-09-051-13/+13
| | | | | | | | | | | | | | | | | | | fails We have no way of knowing if the string was fully processed or got truncated because of a parse error so it is better to use the original path if finding an image sequence fails. We do this by explicitly falling back to the PT_NONE mode if the provided filename is not a valid pattern but the file exists or if the IO context is already open. This also means that filenames no longer need to be escaped even in sequence mode if an invalid sequence (a sequence without %d) is provided, so a command line such as ffmpeg -f image2 -i "100%.jpg" will just work, but "100%%.jpg" will no longer work.

* avformat/whip: fix potential 8bit overflow for profile_idcJack Lau2025-09-051-6/+5

| | | | | | | | | | | | profile_iop is an 8 bits field. Previous code copied AVCodecParameters::profile (which can contain bits beyond 8 bits) into profile_iop, producing overflow and wrong values.
