Bug 549680 – media-video/mplayer-1.2_pre20150214 pa_stream_write() failed: Invalid argument with >=media-sound/pulseaudio-6.0

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Matthew Stapleton 2015-05-17 04:27:28 UTC]

Since pulseaudio commit: https://github.com/pulseaudio/pulseaudio/commit/150ace90f3808bbb7240e18a11140d66a7bda146 (stream: Fail on client submitting non-frame-aligned memblocks) (applied to Pulseaudio release: 6.0), mplayer sometimes gets pa_stream_write() failed: Invalid argument when sending audio to pulseaudio.  When playing with 6 channels, I always get the error.  This is because mplayer doesn't align the audio output to the current frame size when sending audio to pulseaudio.  There is also a bug report here: https://bugs.archlinux.org/task/44937 .

I have created a patch based on how mplayer's alsa driver aligns the frames which appears to fix the problem.

Reproducible: Always

Did you forwarded the patch to upstream? Thanks!

[Comment 3 Matthew Stapleton 2015-05-26 09:12:12 UTC]

No.  Should I do that?  This patch may be needed to be back ported to stable versions of mplayer and/or improved as well before pulseaudio 6.0 is marked as stable in portage.

[Comment 4 Pacho Ramos 2015-05-26 20:58:10 UTC]

yes please, forward it to upstream to not need to carry the patch forever
