[FFmpeg-user] ljpeg colorspace non auto?

[Roger Pack]

Hello all.
I noticed this output:


ffmpeg.exe -i a10.avi -acodec libmp3lame -vcodec ljpeg affv1.mov
https://gist.github.com/2838741

results in:
[buffer @ 01D4FF80] w:1536 h:600 pixfmt:yuv422p tb:1/1000000 sar:0/1 sws_param:
[ljpeg @ 034659A0] colorspace not supported in LJPEG
Error while opening encoder for output stream #0.0 - maybe incorrect
parameters such as bit_rate, rate, width or height

"other" codecs will automatically insert a rescaling filter, does this
one not?  Any thoughts here?
Thanks!
