Hi

I seems to have a gstreamer problem:

[brice@TuxBox:~]$ gst-launch-0.8 filesrc location=mp3/infectious_grooves/groove_family_cyco/made_it.mp3 ! spider ! alsasink
RUNNING pipeline ...
ERROR: from element /pipeline0/alsasink0: Could not get/set settings from/on resource.

whereas:

[brice@TuxBox:~]$ gst-launch-0.8 filesrc location=mp3/infectious_grooves/groove_family_cyco/made_it.mp3 ! spider ! osssink


works.

Why aren't you filing this in the GStreamer bug tracking system like it says?
Comment by Jan de Groot (JGC) - Saturday, 21 January 2006, 17:15 GMT
Please try again with the latest gst-plugins release I updated today. If it fails with this release, please supply us with the first 300KB of your soundfile.

Hello


It still fails and this whenever the sound file is.

After cuting the file to 300K, I tried again to play the reduced file and it worked... No idea what the point is!

Therefore you won't find any file here.


Best regards,

Brice

What soundcard do you have? My theory on this one:
- your soundcard only supports one samplerate (48KHz)
- by cutting the file to 300K gstreamer doesn't know how to determine the correct samplerate
- spider knows how to decode the MP3 file, but delivers it as 44KHz to the alsasink
- alsasink won't play it because your alsa driver wants 48KHz.

Why it works with OSS: the osssink in gstreamer is quite hacky. It detects many wrong things and corrects it automatically. If you stuff something in the wrong samplerate to OSS, it will convert it, or at least play it at the wrong speed.

Try this one:

gst-launch filesrc location=blabla.mp3 ! spider ! audioconvert ! alsasink

It should work, as audioconvert converts between the stream that spider gives and alsasink wants.

I use the module snd-via82xx.

lspci gives: 00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 50)


Your command does not work:

[brice@TuxBox:~]$ gst-launch filesrc location=track1.mp3 ! spider ! audioconvert ! alsasink
RUNNING pipeline ...
ERROR: from element /pipeline0/alsasink0: Could not get/set settings from/on resource.

[brice@TuxBox:~]$


However, I got it working by putting "options snd-via82xx dxs_support=5" in /etc/modprobe.conf
