Pipeline stalls

Updated the subject line.

Please ignore the earlier message.

Hello All,

I am trying to run audio thru pipeline. The control stalls at PREROLLING.

I see a warning and an error prior to prerolling state. I am not sure from where they are popping and why.

Can someone please let me know

1) what is the root cause of below warning and error. Would it harm the audio playback?

2) what i should be checking for the pipeline stalling at PREROLL.

Thanks in advance.

Re: Pipeline stalls

Are you looking for the pipeline construction command-line?

$ gst-launch filesrc location=/my/home/audio.wma ! ffdemux_asf ! my_wma_decoder ! my_sink

You shouldn't use ffdemux_asf. Use asfdemux instead.

If it _still_ doesn't work, then it's almost certainly a bug in your
wma decoder plugin - that we don't have any information about, so we
can't help you with it.

The glib assertion failures you showed suggested that you didn't
create/register the gobject for your WMA decoder element correctly.

Re: Pipeline stalls

In reply to this post by Sin-2

Try to use gst-debug-level=5 to see all debug information, it helped me a lot on such situations. Without knowing better my_wma_decoder and my_sink is hard to help more.
