Description of your issue, suggested solution and other information

As shown above, when trying to download a video from cbc.ca (http://watch.cbc.ca/share/episode/38e815a-00b89eedc76), it fails during the audio step due to an ffmpeg audio bistream filter that is incompatible with the ac3 audio codec of the video. It looks like the bistream filter only applies to aac, which this clip does not use.

I am therefore left with only a video-only file Squirrels-38e815a-00b89eedc76.f8006.mp4. And a zero size Squirrels-38e815a-00b89eedc76.fAC3-5_1-English.mp4.part file where the audio was supposed to go.

[joetex72]

Did you try extracting audio only and then manually merging video+audio after? Might be a temporary fix.

[kevmitch]

That fixes it thanks. My temporary fix was just to remove the bitstream filter from the command line.
