[Libav-user] avcodec_encode_video2 usage question

[Arthur Muller]

Hi Talgorn,

 

I found a way to make it work but don’t really know why this is the case.
The original example had “emit one intra frame every frame at most”, with
c->gop_size = 12.

 

I changed that to 1, and everything seems to work just fine.

 

Also, I have a bitmap image of each frame. I convert each image to YUV
format – which I verify with yuvplayer. Since the change above seems to have
made it all work out, this is probably what needed to be done. But I would
appreciate it if somebody could give me a brief explanation or point me to
one.

 

Thanks.

Hi,

 

Based on what you describe, it seems that you proceed the right way.

I understood that you encode from a set of YUV file, right ?

How do you read these images before encoding them ?
