gstmpg123's Issues

Usage Question

Hello,

First off, thank you for creating this! Second I am not sure if this is the correct place to post this or not, I just have a usage question. I have built without issue but cannot seem to get a pipeline to run : /. I am trying from the command line and i am using GStreamer 0.10.36 and MPG123 1.22.1. I have everything cross-compiled for ARM. Here are the commands i am trying:

gst-launch-0.10 filesrc location=jcash_hurt.mp3 ! mpg123 ! audioconvert ! alsasink device=allx

This one gives the following error:
Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstMpg123:mpg1230: The stream is in the wrong format. Additional debug info: ../../src/gstmpg123-0_10.c(425): gst_mpg123_handle_frame (): /GstPipeline:pipeline0/GstMpg123:mpg1230: Output sample format could not be used when trying to decode frame. This is typically caused when the input caps (often the sample rate) do not match the actual format of the audio data. Input caps: <mpg1230:sink> ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Caught SIGSEGV accessing address (nil) exec gdb failed: No such file or directory Spinning. Please run 'gdb gst-launch 1785' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

Then if i declare the caps:
gst-launch-0.10 filesrc location=jcash_hurt.mp3 ! 'audio/mpeg,mpegversion=1,layer=3,rate=44100,channels=2' ! mpg123 ! audioconvert ! alsasink device=allx
It runs with no errors, but the pipeline completes in a few seconds and no output is heard : (.

I am not sure if i am doing something wrong or what. The pipeline works fine if i use mad:
gst-launch-0.10 filesrc location=jcash_hurt.mp3 ! mad ! audioconvert ! alsasink device=allx
