[21:37] <cbsrobot> wow that's a nice bug
[21:37] <cbsrobot> happens only 1 time out of 4
[21:37] <cbsrobot> http://ffmpeg.org/trac/ffmpeg/ticket/1097
[21:38] <cbsrobot> and with -threads 1 I hit it all the time
[21:38] <cbsrobot> with -threads 4 only every other time
[21:39] <cbsrobot> and when it succeeds, only the bottom row seems to have issues (red / green dots)

[22:08] <CIA-17> ffmpeg: Support flicvideo with 904 bytes extradata.
[22:08] <CIA-17> ffmpeg: Fixes ticket #1234.
[22:38] Action: mystica555 asks here as well, it could be considered a development question: is there something materially different between -vf filter; and -filter:v filter; ?  -'vf yadif' produces expected results; '-filter:v yadif' does not- the output video is still interlaced.
