Why are these different?
Looking only at the first 5 video frames:
ffmpeg -ss 20.061708333 -copyts -i %SOURCE% -map 0 -c copy -sn -dn -muxdelay 0
%TARGET%
produces this:
0, 2846606, 2854113, 3753, 640646, 0x3a5a0c45
0, 2850360, 2850360, 3753, 640646, 0xfed1d09a <== error

ffmpeg -copyts -i %SOURCE% -map 0 -ss 20.061708333 -c copy -sn -dn -muxdelay 0
%TARGET%
produces this:
0, 50062, 61323, 3753, 640646, 0x12a26bc2
0, 53816, 53816, 3753, 415846, 0xb16fcb71 <== error
0, 57569, 57569, 3753, 123879, 0xf2721eb8 <== error

They have the same '-copyts'. They should have the same DTSs & PTSs. They don't.
They have the same '-muxdelay 0'. They should both have no delay. The 2nd has
delay.
The packet with CRC=0x3a5a0c45 is packet 0 in the first and packet 264 in the
second.
'showinfo' shows only frames and uses bogus PTSs. 'framecrc' shows only packets, not frames. So it
doesn't seem possible to correlate their information.
--Mark.
