MPEG-2 decoder too slow to keep up - regression 0.4->0.6cvs

Hi,



If I import an MPEG-2 format clip, I find that playback does not keep pace with the audio in the clip itself. In version 0.4, packaged for Ubuntu, although I couldn't play such a clip on the timeline I could play it successfully in the Clip window. I am running a San Diego core Athlon64 (Socket 939) clocked at 2.2GHz; the governor does raise the CPU speed to maximum during playback.



Any ideas?



(I'd love to be able to ditch Windows completely...)



Regards,

SDM.

Did you install latest MLT and ffmpeg/libavcodec packages?

The MLT installed is that from CVS, as installed by the CVS build script someone posted. The libavcodec and libavformat libraries did not change across versions, as it is the Ubuntu-packaged library from ffmpeg CVS dated 20060823 (the Debian version is 3:0.cvs20060823-3.1ubuntu1 )



I need to use current CVS for these too?

The problem I was having has been cured by an upgrade from single channel DDR200 (actually downclocked DDR266) with default timings to a pair of DDR400 modules with reasonably tight timings, operating in dual channel mode. I gave up attempting to build further libraries from CVS because of the dependencies they carried with them regarding the rest of the packages I had installed - it got very tedious. However, the build with the packaged MLT libraries now works. So there's an added slowness in there somewhere.
