Hi all,
this is my first post to the list.
I'm writing an application which needs to write a video to disk after
processing its frames. Up until now, I've been happy with the
guess_format() function, which produces a video with the following
characteristics (copy & paste from dump_format()):
Output #0, avi, to '../Images/out_all.avi':
Stream #0.0: Video: mpeg4, yuv420p, 320x240 [PAR 0:1 DAR 0:1],
q=2-31, 9999 kb/s, 15.00 tb(c)
And this works like a charm, as the input video has exactly 320x240
sized frames. But now I need to output 640x240 frames (basically, the
original frames put side by side with their processed versions). I've
been looking through the code but can't find a way to do this; I
couldn't even understand where is assigned the head of the
AVOutputFormat list used by guess_format().
Thank you a lot and regards,
Emanuele
