Fwd: Need help to construct a pipeline

[Mayank Aggarwal]

Hi Gstreamer experts,

I am a beginner with gstreamer so bear with me.

I have a working pipeline where audio and video from a test source is sent
to the webrtcbin element used to send out offer. Pipeline is as follows:

PIPELINE_DESC = '''
webrtcbin name=sendrecv stun-server=stun://stun.l.google.com:19302
 audiotestsrc is-live=true wave=red-noise ! audioconvert ! audioresample !
queue ! opusenc ! rtpopuspay !
 queue ! application/x-rtp,media=audio,encoding-name=OPUS,payload=96 !
sendrecv.
 videotestsrc is-live=true pattern=ball ! video/x-raw,width=320,height=240
! videoconvert ! queue ! x264enc ! rtph264pay !
 queue ! application/x-rtp,media=video,encoding-name=H264,payload=97 !
sendrecv.
'''
However doing this consumes a lot of CPU/Memory as gstreamer has to encode
audio/video. Hence I was to use a pre-recorded file to lower the resource
usage.


I want to use a sample file (sample.mp4) to send audio and video to the
webRTCbin element. The mp4 file has H264 video and AAC audio. I have tried
a lot of combinations of elements but it is not working. Could you please
help me correct my pipeline?

PIPELINE_DESC = '''
webrtcbin name=sendrecv stun-server=stun://stun.l.google.com:19302
 filesrc location=sample.mp4 ! decodebin ! audioconvert ! sendrecv.
 filesrc location=sample.mp4 ! decodebin ! videoconvert ! sendrecv.
'''

Many thanks in advance.

Thanks,
Mayank
