Hi,
I am a bit new to GStreamer and Davinci. I am trying to pack compressed audio with compressed audio together in a container file but my pipeline seems to lock without any indication before writing anything to the container file.
The pipeline I am trying to use is the following:
gst-launch -v v4l2src always-copy=FALSE num-buffers=600 \
! 'video/x-raw-yuv, format=(fourcc)NV12, width=1280, height=720, framerate=(fraction)30/1' \
! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE bitRate=3000000 \
! queue ! mux. \
alsasrc num-buffers=880 ! audioconvert \
! 'audio/x-raw-int, endianness=1234, signed=true, width=16, depth=16, rate=44100, channels=2' \
! TIAudenc1 codecName=aaclcenc engineName=codecServer \
! queue ! mux. \
avimux name=mux ! filesink location=test.avi
The shell output of this pipeline is:

If I remove the line that encodes the audio(TIAudenc1 codecName=aaclcenc engineName=codecServer) , the pipeline works but obviously packs raw audio instead of compressed audio.
I have also tried with qtmux instead of avimux with the same result.
I have also tried to use the audio codec alone and it works fine:
gst-launch -v alsasrc num-buffers=1000 \
! audio/x-raw-int, endianness=1234, signed=true, width=16, depth=16, rate=44100, channels=2 \
! queue ! TIAudenc1 bitrate=64000 engineName=codecServer codecName=aaclcenc ! filesink location=output.aac
Is there a reason why the pipeline not working?
