Summary of the bug:
In Windows 1803
This:
ffmpeg -i IN -filter_complex
"telecine=pattern=5,split[A][B],[A]select='not(eq(mod((n+1)\\,5)\\,3))'[C],[B]select='eq(mod((n+1)\\,5)\\,3)'[D],[C][D]interleave"
OUT
succeeds.
But this:
ffmpeg -i IN -filter_complex
"telecine=pattern=5,split[A][B],[A]select='not(eq(mod((n+1)\\,5)\\,3))'[C],[B]select='eq(mod((n+1)\\,5)\\,3)',pp=linblenddeint[D],[C][D]interleave"
OUT
fails.
Due to the delayed nature of the failure, I wonder whether its cause might
be the same as 'https://trac.ffmpeg.org/ticket/8612'.
Without pp=linblenddeint:
CPU utilization is steady between 85% & 95%. Output is about 13 GB.
Playback: Normal.
With pp=linblenddeint:
CPU utilization is erratic, generally below 35%, sometimes below 10%.
Output is about 1 GB.
Playback: Total time is not correct. It begins at zero and advances,
keeping just ahead of running time. Video freezes when total time reaches
19:01.
I have tested this with 2 M2TS files and 2 VOB files.
Thank you for making ffmpeg. Thank you for maintaining ffmpeg.
