Description

I'm not sure if this is avformat or avcodec

How to reproduce:

This is a stream dump of a webcam with fps=0.5.

I can provide a private http streaming test account on my private cam to a limited group of developpers when necessary.

  • Keywords regression added
  • Priority changed from normal to important

Could you confirm that you see the same problem with the stream you attached and if you try to decode the original http stream?

Or does the sample you attached show one problem (Unable to parse option value "0/0"), but there is another problem if you try to decode a stream from your camera?

I confirm, that there is the same error with the stream directly read by ffplay:

lavfi trips over 0/0 sample aspect ratio.

Possible solutions:
1st: modify mjpedec.c and make 0/0 into 0/1
2st: teach lavfi to assume invalid aspect ratios are 1/1
