FFmpeg can now demux WTV ... helpful for Comskip?

Post by TonyXL »

I saw an earlier post where you state WTV support would have to wait until someone reverse engineered WTV. The latest FFmpeg (http://ffmpeg.arrozcru.org/autobuilds/) can demux WTV! From the changelog:

- Windows Televison (WTV) demuxer

I tried it and it was able to extract the audio and video streams from one of my WTV's. I would be very grateful if you could take a look at the FFmpeg source if you get a chance.

Thanks!

I build ffmpeg from the latest sources but it crashes on all .wtv files I have.
So progress will be slow.

Hi Erik, thanks for trying so quickly.

Here is a WTV that I was able to demux (1 minute USA clear QAM mpeg2):

I used the static binary from Jan 17:
http://ffmpeg.arrozcru.org/autobuilds/f ... -static.7z

Here was my command line:
ffmpeg -i fox.wtv -vcodec copy fox.m2v -acodec copy fox.mp2

Tested playback using:
ffplay fox.m2v
ffplay fox.mp2

Hopefully this is helpful. Let me know if you want different or longer samples.

Thanks,
Tony
