Yocto Dizzy 1.7.1

Image built: fsl-image-multimedia-full

Board: i.mx6 SabreLite

When launching this simple gsteramer pipiline:

# gst-launch-1.0 filesrc location=mp3/fly.mp3 ! decodebin ! audioconvert ! volume volume=1.0 ! alsasink

everything is ok. But if I set the volume level to something different from exactly 1.0 I ear no

audio anymore.

Tried with different values (0.90, 0.1, 0.99999999,, etc) with same result.

Same problem with gst-launch-0.10 and/or jackaudiosink.

Already tried to put audioconvert/audioresample plugins in different locations.

I inserted a 'level' plugin to measure the audio level and noticed that when volume

is not 1.0 the output level is incredibly low and always like:

rms=(double){ -699.99999984363217, -699.99999984363217 }, peak=(double){ -349.99999992181608, -349.99999992181608 }, decay=(double){ -349.99999992181608, -349.99999992181608 };

which seems floor noise to me...

I've also tried using mad/beepdec directly without decodebin and th resut is the same...

Also same results playing a wav file, so I guess it is a frescale-alsasink specific problem,

but there I'm lost...

Any help greatly appreciated :-D

Complete logs below. Tnx.

Complete log with gstreamer-0.10 and volume set to 1.0 (audio ok):

# gst-launch-0.10 -m -v filesrc location=mp3/fly.mp3 ! decodebin ! audioconvert ! volume volume=1.0 ! level interval=1000000000 ! alsasink

Tested and can confirm that the above patch solves the problem :smileyhappy:

Attached you can find a recipe with the above patch for gstreamer1.0 and one adapted for gstreamer0.10.36.

Simply uncompress it in your private layer and do:

$ bitbake -c cleanall gst-plugin-base

$ bitbake -c cleanall gstreamer1.0-plugins-base

With next image rebuild you should have both gstreamers correctly patched.

Hope this helps. Ciao.
