omxmjpegdec doesn't stop processing after receiving EOS
Submitted by chw..@..oo.com
Link to original bug (#742172)
Description
To reproduce:
- gst-launch-1.0 -e filesrc location=
<any mjpeg encoded video file>!<fileformat>emux ! omxmjpegdec ! fakesink
2a. either wait for the video conversion to be "completed"
2b. or press Ctrl+C to interrupt the process - gst-launch-1.0 stucks at "Waiting for EOS..."
Note: I reproduced this bug with three mjpeg encoded files, with different formats and resolutions.
The command gst-launch-1.0 -e filesrc location=<any mjpeg encoded video file> ! <demuxer> ! omxmjpegdec ! fakesink gives the following output:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...

New clock: GstSystemClock
^Chandling interrupt.
Interrupt: Stopping pipeline ...
EOS on shutdown enabled -- Forcing EOS on the pipeline

Then it hangs until I interrupt it again
Partial log of the same command with --gst-debug=4:

Remarks:
- It also breaks decodebin because decodebin may use omxmjpegdec to decode mjpeg videos
Workaround:
- use jpegdec instead of omxmjpegdec
