I am trying to access a USB camera in a i.MX6 board through gstreamer. I am able to read and save the video stream or the audio stream when taken alone, but whichever gstreamer pipeline I used that reads both audio and video at the same time I get an error: "retire_capture_urb: XXX callbacks suppressed" and the board become unresponsive.
This happens with every USB camera I tested.
This is the gstreamer pipeline I used (but tested tens and all give the same error):
gst-launch -e -i matroskamux name=mux ! filesink location=video.mkv v4l2src device=/dev/video1 do-timestamp=true ! jpegdec ! vpuenc codec=0 ! mux. alsasrc device="default" provide-clock=true do-timestamp=true ! queue max-size-time=10000000000 max-size-bytes=104857600 max-size-buffers=2000 ! mfw_mp3encoder sample-rate=32000 optmod=0 bitrate=32 ! mux.
Notice that the same pipeline works perfectly if I access video from the USB camera but audio from another source (e.g., the internal mic).
I am using yocto but the same happens with an Ubuntu based distribution I was able to setup.
Any suggestion?
Regards
G.
