Comment (by chconnor):
Yeah I can't try the asetpts with -c:a copy. When I specify -c:a
pcm_s16le, then using asetpts will generate a working file (with non-
monotonic errors and rational-seeming pts in the ashowinfo), but as tested
above, specifying pcm_s16le alone also generates a working file so I'm not
sure if that generated any useful info?:
{{{
ffmpeg -f alsa -ac 2 -i hw:CARD=Cx231xxAudio,DEV=0 -c:a pcm_s16le -af
"asetpts=PTS-STARTPTS" test-asetpts.avi
}}}
(Let me know if there is a smarter way to try asetpts without specifying
-c:a pcm_s16le or -ar 48000, etc.)
Thanks for working on this.
