skipping frame! error?

[v0llrath]

hello and sorry if this has been covered before but a quick search didn't yield exactly the problem i seem to have encountered... i'm simply using ffmpegx to downgrade a high-res video file (which is unplayable on my 5 year old computer haha) which i've done many times before, but for some reason this one doesn't seem to work. can someone take a look and possibly tell me what's wrong?

then it just hangs. i let it run for like 48 hours before giving up.

any help is appreciated.

Moving you to our ffmpegx section.

It seems from this log that you didn't downscale at all. The output that ffmpegX was working on, was still 1280x720; the same as the source file. Such a resolution would require close to 5000 kbps for XviD, not 940.

P.S. Is your profile correct, that you're running 10.5.8 on only 64 MB RAM? I would expect at least 10 times as much...

[v0llrath]

haha no that's ram on the video card. okay i'll try to scale down and see what happens.

no good.. this is now the error message:

Not sure what this means, but I wasn't expecting negative numbers, and I expect neither was mplayer.

Apparently it has trouble reading the framerate and bitrate.

I'd suggest trying a conversion that doesn't involve mplayer/mencoder.
Not sure what else to diagnose without access to this source file.
