Bug#869660: ffmpeg: choppy video playback in Kdenlive & VLC in sid

[Vincent Pinon]

Hello,

I don't see the problem anymore, neither on stable/testing/unstable (all upgraded since then).
I'm sorry my analysis of the situation was not very clear at the time of reporting, and then I've been very slow to react :(
Please close the ticket...
and thank your for your fantastic work!
