|
|
Hi,
I'm not sure if ffmpeg is guilty but after upgrading ffmpeg from 0.10.6 to 0.10.7 I notice that even SD (300x500) movies aren't smooth. What could I check to isolate problem.
I use:
AMD/ATI HD6320 (from AMD E-450)
mplayer2-2.0_p20120828
smplayer-0.8.3 |

Do you use the open source drivers and have VDPAU enabled for mesa? If so, disable it.
Only if you have a kernel which is patched for UVD and >=mesa-9.2_pre20130404 then VDPAU becomes useful. Else it will attempt to decode certain video formats using shaders with often suboptimal results. |

It could be that mplayer chooses a suboptimal video output (VO). Check the messages that are printed by mplayer to the shell. With the radeon driver and in absence of UVD acceleration, -vo xv is preferable. |
