Set state getting hanged

ramakrishnakama — Tue, 30 Jun 2015 10:53:03 GMT

Set state to stop getting hanged if we remove USB while playing attached file.

Once USB removed, we are trying to stop playback, But gst_element_set_state() API returning after 2-3 seconds.

We observed aiurdemux trying to push pad buffer and which is failing continuously.

Our pipeline is

gst-launch-0.10 filesrc location=20077693327861 - Copy.wma typefind=true ! aiurdemux name=demux demux. ! queue ! beepdec ! audioconvert ! volume ! alsasink

We are using gst-fsl-plugins version 3.0.8 and gstreamer version 10.36.

BSP version is 3.0.35 based customized BSP.

Board is IM6 solo based customized board.

This issue not reproducing with gstreamer ugly plugin asfdemux.

But we are facing other, many seeking related issues with asfdemux and production is very close, so we can't change to asfdemux.

This is very urgent, for a production program. SOP is very close.

Please help us analysing this ASAP.

Hi joanxie

We observed with this wma file very easily. Removed USB while playing time is around 6 second.

With playbin2, we can't reproduce this scenario. Because we can't set state or stop while playing and it continue to play till it has data.

Our use case, when USB removed, we call set state to stop. That set state to stop is getting hanged for 2-3 seconds.

We are using hardware audio device, so two playback can't be done simultaneously.

We have to stop playback as soon as USB removed, So that playback will start from previously playing device (SD/CDDA/CDROM).

Please let me know if you have any queries.

Thanks and Regards,
