mplayer sticky pause

[nevion]

Not sure if this is a PA problem or an mplayer problem but... I've got an intel8x0 on my desktop and an hda intel on my laptop. I currently use opensuse 11.1 and MPlayer-1.0rc2_r27637-3.pm.3 and pulseaudio-0.9.12-9.5 . Whenever I unpause mplayer, it likely gets stuck there and while mplayer still reacts to user input, it unfreezes if you seek around. Other times it resumes for an instant, the audio pauses and the video keeps going for IDK, 1.5 seconds - then the audio skips and everything catches back up. And maybe 10% of the time it actually resumes with no problems.

I set ao=pulse or ao=alsa and the result is the same. It does not happen if I prevent alsa from using PA and output directly to it (=killing PA). Didn't happen with older versions way back when so this is a new development. And one that drives me nuts.

I also vote for this, because I have same problem

Works fine for me on -ao alsa with MPlayer 1.0-1.rc2 and pulse 0.9.10 and git master and alsa-plugins 1.0.18.

With -ao pulse does sometimes exhibit this behaviour but this is likely a problem in the mplayer pulse output layer itself and I'm not sure who maintains that.

coling,

I imagine it happens with alsa because I have alsa output by default to pulseaudio - it definitely works if I change that.

I'm having same problem, if there is a video, mplayer will sometimes continue to play, but never if there is only an audio.

It just sleep for a while in fill_audio_out_buffers, then asks for pa_stream_writable_size for the stream, result is zero so there is nothing to write, and repeats it forever.

I have mplayer SVN-r28234 and Fedora 10 pulseaudio (pulseaudio-0.9.13-6.fc10.i386).

Got a report over at mplayer for this bug http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1408

Seems there's a reliable method to trigger it now (comments 6 and 8). It would seem that PA is at fault but this is not necessarily the case.

[lennart]

This is fixed now in http://git.0pointer.de/?p=pulseaudio.git;a=commit;h=e61728e67a656c0bbd12b13bb4c1777d0e3163f4

Sorry for the long delay.

I am experiencing nearly identical symptoms using MPlayer SVN-r30325-4.4.2 and pulseaudio 0.9.21 on arch linux. However, in my case it seems to be limited to sticking/freezing after unpause (the audio doesn't go out before the video etc).

Additionally, I get skipping audio in vlc media player (somewhat like OP says he has in mplayer). VLC never freezes on unpause, but the audio will periodically stop, then resume fast to catch up, then play at normal speed, then stop again in a cycle. If I watch pulseaudio's Volume Control's Playback tab, I can see the VLC alsa plugin disappear coinciding with the lapses in audio, and reappearing when the audio returns. VLC version is 1.0.4.

Both of these apps are using alsa (which in turn is using pulseaudio's alsa plugin). Alsa version is 1.0.22.
