Issue:

In rpi4 platform we are seeing issues with playing MPEG2 streams while no issues in playing H264 streams.

Requirement:

To find a way to play MPEG2 streams through software decoders in Rpi4 platforms.

Software Decoders available in gstreamer :

Below were the software decoder plugins available for MPEG2 streams:

       2. mpeg2dec

       3. v4l2mpeg2dec

1. avdec_mpeg2video :

Need to check on the steps to install this plugin in the Rpi4 RDKV platform
