Hi Forum,
We've just upgraded to TI SDK 6.0 and we started to see framerate dropping when we record from LCD screen with an USB microphone. We are using the following pipeline and we didn't have this problem when we were using TI 5.0.
gst-launch-1.0 -e v4l2src device=/dev/video11 io-mode=5 ! video/x-raw,format=NV12,width=1024,height=600,framerate=30/1 ! ducatih264enc level=level-51 profile=high bitrate=8000 ! h264parse ! mp4mux name=mux ! filesink location=/home/root/test0.mp4 alsasrc device="hw:2,0" ! queue ! audioconvert ! avenc_ac3 ! mux.
Without the audio queue, the framerate is 39fps but it drops to 14fps when the alsasrc queue is attached and the video looks really laggy.
Any idea why and good suggestions to the problem?
Thank you very much!
Bohan
