[FFmpeg-user] ProRes Invalid pixel format string

[Alok]

Hello,

I'm trying to use ffmpeg to crop, rotate, and encode ProRes 422 videos into
JPEG Image sequences. I'm running on Mac OS X 10.7, and have tried the
following configurations, based on other threads I've found:

--enable-libmp3lame --enable-shared --disable-mmx --arch=x86_64

--enable-libmp3lame --enable-shared --disable-mmx --arch=x86_64
--enable-gpl --enable-version3

I've also tried adding -vf "format=yuv:420p" to the command without success.


Using any of these configurations yields a result similar to this:

sneezy:ffmpeg admin$ ffmpeg  -i "video.mov" -an -f image2 -vf "crop
4090:3106:6:0" -vf "transpose=1" "imgseq_%05d.jpg"
