For those of you having the periodsize error with mplayer+alsa+dmix, you need to make an adjustment to the mplayer source code. In libao2/ao_alsa9.c in the mplayer source:
| Code: |
-if ((err = snd_pcm_hw_params_set_period_size(alsa_handler,alsa_hwparams, chunk_size, 0)) < 0)
+if ((err = snd_pcm_hw_params_set_period_size_near(alsa_handler,alsa_hwparams, chunk_size, 0)) < 0) |
should be around line 620 or so. Then compile it and install. Alsa+dmix will work, but sometimes it will play too fast. This is cause by the rate getting set to 22000 or somesuch. Just manually set it to 44100 in your asoundrc, and you should be good to go. Then again, YMMV.

Thanks, this fixed my MPlayer problems  Can you please file a bug on BGO, I think this patch should be included in the ebuilds.

hmm... i added the .asoundrc as described in https://forums.gentoo.org/viewtopic.php?t=122076,
and it works,
but...hmmm....
i still need to do more testing, but it seems that the video is smoother when mplayer uses the raw/normal/whateverishisname alsa device.....
could anyone else check it too? maybe it's only my eyes ) |

Argh! I was looking for this post! Anyway, I posted another topic about mplayer and dmix which has a better fix. You might want to try that as well if you found this to be effective.

darckness:
i already have mplayer from cvs, so that's not the problem. it WORKS with dmix, i mean i can watch 2 movies at the same time with sound.
the problem is that it's not that smooth as when used with the 'raw' alsa output.
i verified it, i created a script, which randomly started a video file with either 'raw' alsa or with 'dmix' alsa, and then when the video stopped, displayed me what mode he used.
i could guess for 99.9% when it was raw, and when dmix.
so there's a difference.
i admit it's not that big, but it's still there. |
