[meta-fsl-arm] GStreamer mp3 playback on Nitrogen6X - seg faults

[meta-fsl-arm] GStreamer mp3 playback on Nitrogen6X - seg faults

[Erik Botö]

Hi,

I tried building the fsl-image-test + gst-plugins-good-id3demux to
enable mp3 playback using gst-launch. But when doing gst-launch
playbin2 uri=file:///path/to/mp3 gst-launch segfaults. If I build
another image with the mad-plugin for gstreamer, and remove
libmfw_gst_mp3dec.so so the mad-plugin is used it plays ok.

Has someone else tried to use the gstreamer plugin provided by
libmfw_gst_mp3dec.so for mp3 playback?

Cheers,
Erik

I have not.

Could you, please, share the demux, decoder, audio sink you've been 
using in each case? (with and without FSL mp3 decoder)

I will give it a try using my imx6qsabresd board (I don't have nitrogen)

Hi,

Would be great if you have the chance to test, so I know if it's just
me :) I think there shouldn't be a difference between SabreLite and
Nitrogen6X on this issue.

I tried to identify the key elements in the gstreamer pipes:

Working:
id3demux
mpegaudioparse0
mad
pulsesink

Crashing:
id3demux
mpegaudioparse0
mfw_mp3decoder
pulsesink

Cheers,
Erik

It'd be good to open a bugzilla issue for it so we can track progress
on this issue.

Can you open and put all details there?

I was able to reproduce it on imx6qsabresd:

der ! alsasinkesd:/home# gst-launch filesrc location=/home/sax.mp3 !

It doesn't seem to be target specific - also fails on the SabreLite

Hi all,

Thanks for helping me verify that the bug exist for other boards and
builds as well. I have created a bugzilla entry where I tried to
capture the info in this thread,
https://bugzilla.yoctoproject.org/show_bug.cgi?id=4449

Cheers,
Erik
