Title: WebM
Post by: Jan Gruuthuse on February 29, 2012, 10:05:28 AM
Avidemux v2.6.0 (r7745) reads the WebM videos. However Veronica Belmont looks a little smurfish?

Great news, but I segfault: 11, exec_bad_access, when I try it with 2.6 r7745.  Will you paste in a few things for me to see how it starts off?  Here's my output when it tried to determine the file type. (https://gist.github.com/1940228)

For the smurf part, try inverting u&V in decoder options

You can use the Swap UV filter.

Thanks: works when re-encoding and preview of filter.

I can load that file in 2.5 and 2.6 now using libvpx but not without it.
2.6 crashes during no decoder found searching lavc I think.


Code Select
Vorbis init successfull

Where it says Painting dummy openGl, that happened when I got the two errors:

So it works with Libvpx and that's good for now.

Doubt: read and write, or just read-only? I am eagerly expecting Avidemux to support WebM/VP8, so I can hardsub videos without having to resort to encoding to H.264 and back to WebM.
