Add support for FFV1 in MOV (999 bytes, patch) 2015-10-14 23:11 UTC, Reynaldo H. Verdejo Pinochet	accepted-commit_now	Details \| Review

Description Patrick Doyle 2014-10-27 17:21:50 UTC

I have a (several, actually) video file that was losslessly encoded with FFv1.  avconv reports:

$ avconv -i data/20141022.d.run1000big.movavconv version
9.16-6:9.16-0ubuntu0.14.04.1, Copyright (c) 2000-2014 the Libav

30 tbr, 30 tbn
At least one output file must be specified

But when I try to play it using playbin, I get:

$ gst-launch-1.0 playbin uri=file:///.../data/20141022.d.run1000big.mov
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

The error reported is "No decoder available for type 'video/x-gst-fourcc-FFV1'".

I can reproduce this error on my Ubuntu 14.04 VM with the following:

$ wget http://docs.gstreamer.com/media/sintel_trailer-480p.webm
$ avconv -i sintel_trailer-480p.webm -vcodec ffv1 -an output.mov
$ gst-launch-1.0 playbin uri=file:///home/wpd/bug/output.mov
