Bug 86907 – "gst-launch-0.8 sinesrc ! alsasink" fails, ".... ! osssink" works (using alsa)

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Carl Jackson 2005-03-27 16:19:20 UTC]

First bug report.  We'll see how this goes, I apologize in advance for any ingoramus mistakes...

Using the Epox 8KDA3+ (amd64) onboard nforce3 (intel8x0) sound chip. 

some commands with output:

> gst-launch-0.8 sinesrc ! alsasink
RUNNING pipeline ...
ERROR: pipeline doesn't want to play.

the above gives no sound output.


> gst-launch-0.8 sinesrc ! osssink
RUNNING pipeline ...

the above plays the sine wave.

Using most recent available ebuilds of gstreamer (0.8.8), gst-plugins (0.8.7), & alsa-lib (1.0.8).

Tried manually compiling gstreamer 0.8.9 and gst-plugins 0.8.8 with some success (i.e. got sound from osssink), but had same symptoms as above with alsasink as well as some other issues, so I reverted back to ebuilds.  Hopefully enough information is contained in attached gst.log.bz2 file to troubleshoot.

gst.log.bz2 output referred to above

output of:

There are ebuilds for gstreamer 0.8.9 and gst-plugins-0.8.8

Just unmask them in /etc/portage/package.keywords

I will look at the log tomorrow.

gst.log.bz2 output referred to above, this time posted as binary

output of:

gst-launch-0.8 --gst-debug-level=5 sinesrc ! alsasink &> gst.log

This time posted (hopefully correctly) as binary instead of text.

gst.log.bz2 output after updating packages

Thanks for the tip, got the packages updated to the current releases (gstreamer
0.8.9, gst-plugins 0.8.8).

Here's the new gst.log after the updates.

Ok.  Been fooling around some more with the system, and have managed to get some sound out of it.  Upgraded gst-plugins-faad to 0.8.8 in between last post and this, for what its worth.

New command:

gst-launch-0.8 sinesrc ! alsasink device="plug:dmix"

Issue now is that sound is choppy (plays for a few seconds, stops/starts, repeats).  Same with other sound files I've tried (flac, mp3), up to point where some (mp3) will completely stall after <0.5 seconds.  Will continue experimenting.  Let me know if there's any additional debug output that would be useful (and how to get it). Incidentally, using osssink still seems to provide ok output.

do u get choppy playback using dmix in mplayer or other audio players?

[Comment 7 Zaheer Abbas Merali (RETIRED) 2005-07-13 05:19:45 UTC]

do you still have this issue? (with latest gst-plugins 0.8.10 and alsa 1.0.9 and
kernel 2.6.12)
