[FFmpeg-user] Conversion from mjpeg to H.264 with 2 overlays failed, trace gives me no idea why ...

This-

> Input #0, mjpeg, from '/Users/jb/test/test.mov':
[...]
>    Stream #0:0, 2, 1/1200000: Video: mjpeg (Baseline), 1 reference
> frame, yuvj422p(pc, bt470bg/unknown/unknown, center), 768x576, 0/1,
> lossless, 7.66 tbr, 1200k tbn

and this-

> [mjpeg @ 0x7f914b508540] sof0: picture: 258x28928

really make me wonder about what's inside that file. Looks like the metadata 
and actual frame data don't agree at all- 768 x 576 vs 258 x 28928, and 
neither is a nice multiple of the corresponding value. It also looks like 
there are different size frames there, and IIRC ffmpeg doesn't handle that 
gracefully.

How does the file play with ffmpeg or vlc? are there errors or a change in 
frame size?

Later,

z!
