A quick test shows that PTS and DTS are already set generically for pcm
formats (unless the AVFMT_FLAG_NOFILLIN flag is set). If it is not in
your usecase, then you should provide details about this (preferably by
opening a ticket on trac).

The purpose of this patch is to calculate pts and dts when using pcmdemux.
Is there anything wrong with doing this, or do you have any suggestions for
improvement?

1. Don't top-post on this list.
2. PTS and DTS are already produced with this demuxer. As has been said:
If it isn't for you, open a ticket about it.

This is the case. I found that when opening a pcm file,
avformat_find_stream_info will keep reading pkt until the number >
max_ts_probe then exit.
The reason is that when demux pcm was used, valid pts and dts were not
read, and sti->first_pts was never set correctly;
This is unreasonable in some scenarios, because
avformat_find_stream_info will consume more time to read pkt, which is
especially serious in the case of network streams;
You can reproduce this problem by opening any pcm file.
Based on the above facts, I submitted this patch;
Of course, this problem can also be fixed by solving the assignment
problem of sti->first_pts, in another patch of mine:
