Description Víctor Manuel Jáquez Leal 2013-12-24 23:20:44 UTC 
The mfc video decoder didn't work in my odroid x2 with kernel 3.8. It failed with this error: "Dequeueing failed" in input_dqbuf(). The error was invalid parameter.

Note that the mfc plugin was just a proof of concept and is going to disappear soonish. It doesn't make much sense to continue working on the mfc plugin.

The new solution will be a video decoder element that uses the infrastructure from the v4l2 plugin. The current WIP is here http://cgit.collabora.com/git/user/nicolas/gst-plugins-good.git/log/?h=v4l2videodec
Comment 3 Víctor Manuel Jáquez Leal 2013-12-25 10:36:18 UTC 
I agree on that, I'll take a look to the new v4l2videodec, but I would say, regarding this mfc plugin, that it is better have it functional rather than broken (at least in the odroidx2 kernel 3.8). Besides, the patch is not very intrusive.

Happy holidays!

Sure, thanks and thanks for the patch :)
