The question is: What does ffmpeg use as its TB in the decoder and
pipeline?

There's no such thing as PTS in mpeg-ts. The transport stream sets the SCR (System Clock Reference)
(aka TB) but the PTSs are in the presentation stream, stored as integer ticks of the SCR.

Thanks, Jim. I certainly didn't expect such a lengthy response. I'll respond
more verbosely.

The Presentation Time Stamp (PTS) value which FFmpeg associates with
video frames and audio data is a 64-bit integer. There is an associated

Hi
I am doing a rtmp push of a live stream from a MIP/UDP input. The feed push
works fine even for a few weeks, but suddenly I could see AV sync issues. I
need to stop and start the feed each and every time, for the feed to work
again. I see only the following log lines. Can someone give me a way
Are these correct?
ffmpeg PTS resolution is 1ms.
DVD & BD PTS resolution is 0.01[1..]ms (i.e. 90x).
The PTS difference between 24Hz & 23.976Hz is 0.0416[6..]ms.
The PTS difference between 30Hz & 29.970Hz is 0.03[3..]ms.
Thanks,
Mark.

Hello!
I'm trying to nomalize an audio file with FFmpeg. I'm using the loudnorm
filter. The source loudness is -23 LUFS and I want to make it -17 LUFS.
As far as I know, loudnorm has 2 modes of normalizing audio: linear and
dynamic (analysing small parts vs. analysing the whole file).

Is there any example to call function "ff_atadenoise_init_x86" in

Hello,
We need to give our users an ability to convert arbitrary video files to
MP4.
Some of these files uses AV1 codec.
I've enabled the use of libdav1d library (which contains decoder only).
Do we really need to include libaom too?
Is it OK (for a generic user purposes) to convert from
