Comment (by Denis Filippov):
Yes, it looks like this is the same problem with streams other than audio
and video. As I see this situation, PTS are taken from all elementary
streams to synchronize between each other. But what kind of data should be
used if the PTS are different? In my case, there is no PTS in the data
stream at all. That is, there is no time increment. The PTS in the data
stream will appear only when the label itself arrives. It will fully match
the required PTS video and audio for synchronization. And speed and time
will be appeared for little time. In ffmpeg version 7, there is a feeling
that video or audio streams are no longer the main ones in time formation,
but there is some kind of mathematics that multiplies time data by 0 if at
least one stream does not have it at the moment. It's easy to fix. If at
least 1 stream contains sound time data, then use it.
