Raw audio MPEG TS streaming

[Charles Chen - Contractor]

Hello,


How to generate mpeg TS stream (RTP payload type 33) with raw audio without using any audio encoder such as AAC? I need to feed raw PCM audio into mpegtsmux and RTP rtpmp2tpay. I am getting pipeline link error if I:


gst-launch-1.0 autoaudiosrc ! audioconvert ! capsfilter caps = "audio/x-lpcm,width=16,channels=2,rate=48000" ! filesink location = "audiofile.raw"


Looks like audio/x-lpcm is not included in the supported media type list:

https://gstreamer.freedesktop.org/documentation/plugin-development/advanced/media-types.html


Do I have to create a new audio/x-lpcm media type? considering possible issues to link with existing elements.


Is it feasible to create my own plugin to convert audio/x-raw to audio/x-lpcm and then link to mpegtsmux?


Or should I use appsrc or appsink method to do that?


Thanks and appreciate any feedback.


Charles
