Summary

0002131: ALSA and SDL problems

Description

Running Kdenlive 0.8.1 from a terminal in Debian Squeeze, I can see lots of messages. One of them happens whenever I'm watching a clip in the monitor and try to rewind it. The message says "ALSA lib pcm.c:7223: (snd_pcm_recover) underrun occured". After this, rewind seems to hang the application, and the clips monitor becomes extremely slow and unresponsive. All the cores of the i7 2720QM show high activity.

I have MLT, Melt, libmlt all in their 0.7.2 version. I am trying to edit MTS videos, using AVI proxy files. By the way, it is very, very often having a statusbar message telling me that SDL cannot open audio because it is in use.

I hope this helps. If the assigned developer needs more information, I'd be glad to provide.

Regards,

Fabricio

Steps To Reproduce

Click on the "rewind" button under the clips monitor, and voila.
