Hello there,
In FFmpeg's HEVC & AV1 encoder wrappers, the private codec option -s12m_tc
, documented as "Use timecode (if available)", is present, but unmapped in

Hello,
Is there a valid technical reason as to why FFmpeg's HLS muxer dropped the
hls_wrap option?
There are many cases where the hls_wrap option remains critical so as to
preserve the set of output file names without increments. This deprecation
breaks that.
For now, this behavior can be worked

Hello there,
Does libx264 in ffmpeg implement embedding pic_timing SEI timecodes?
Following up on a query on StackOverflow related to AWS MediaLive not
picking up on the timecodes on output when libx264 is used.

Hello there,
A quick glance at FFmpeg's main landing page https://www.ffmpeg.org/
confirms that S12M timecode decoding in h264is implemented, and that to
some extent, the NVENC encoder wrappers support it.
Is the same currently supported/implemented in libx264?
