Comment (by ami_stuff):
In this case the file is flipped unnecessary.
libavcodec/mjpegdec.c:
{{{
else if((len > 20 && !strncmp(cbuf, "Intel(R) JPEG Library",
21)) ||
(len > 19 && !strncmp(cbuf, "Metasoft MJPEG Codec",
20))){
- s->flipped = 1;
+ s->flipped = 0;
}
}}}
so it looks like the intel jpeg encoder can save flipped and not flipped
jpeg frames and the question is how to identify which frames should be
fliped and which not.
