[MPlayer-users] Karaoke (cdg) support broken?

[Alec Bennett]

Well, I updated to the latest version of Mplayer (SVN-r38020-7), freshly
compiled, and it pulled the latest ffmpeg during the ./configure process.
I'm still getting the same choppy playback with karaoke CDG files, even
with the -mc 10 option added.

It seems to update about once per second, and be frozen for about half a
second. So it's updating about half the time. Strange. I don't imagine
anyone has any theories?

Using the latest version of Lubuntu.

Output of mplayer ~/Karaoke/test.cdg -audiofile ~/Karaoke/test.mp3:

If I add the -mc 10 option I get the same behavior:

$ mplayer -mc 10 ~/Karaoke/test.cdg -audiofile ~/Karaoke/test.mp3

Let me know if any other information would be helpful.

Any theories very invited!
