Hello,
Testing the various NVENC wrappers, specifically hevc_nvenc in FFmpeg 7
results in the spurious warning above
Sample command:
ffmpeg -threads:v 1 -hwaccel nvdec -hwaccel_output_format cuda
-init_hw_device cuda=cuda:0 -filter_hw_device cuda -extra_hw_frames 3
-nostdin -ignore_unknown

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
back to me if you need anything else I can help with.

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?

Hello there,
Can a standard complex filter graph (initialized via -filter_complex) be
used with an audio filter (inserted via -af) in the same command?
Take this rudimentary example snippet:
ffmpeg -fflags +genpts -vsync 1 \
-threads 1 -dn \
-i

Hello there,
With mpegts output, should global headers be used or not, set via -fflags
+global_header?
And if there are exceptions to that, based on the codec type wrapped in
mpegts, when should global headers be used for mpegts?
I ask because of the dump_extra bitstream filter documentation,

When stripped (without debug symbols) you get the ffmpeg binary.
Debug symbols are useful for function tracing when attached to a debugger,
