V4l2h264dec is not available in Google coral

[Manikandan]

Hi ,

We are trying to receive rtsp video streams with i.MX 8M based boards

when we tried with iMX8MQ EVK Board and iMX8M Mini EVK Board we are getting maximum 24 FPS

but when we try with Google coral board we are getting   8 FPS  Only

Once I debug this i got to know that  iMX8MQ EVK Board and iMX8M Mini EVK Board  OS's using V4l2H264DEC whereas Google coral using VPUDEC

will it be the issue ?

if so i have tried installing V4l2H264DEC plugin in Google Coral's Mendel OS, but i wasn't able to achieve it. can anyone suggest me how to do it ?

The pipeline which we are using :

gst-launch-1.0 rtspsrc location=rtsp://10.0.0.1:9098/stream latency=0 connection-speed=30000 user-id=client  user-pw=password ! queue ! decodebin ! queue ! videoconvert ! autovideosink

Thank you for the response.

Actually the mendel os doesn't have v4l2h264dec. i'm in the process of adding it. can you tell me any way to add this v4l2h264dec plugin

Hello Manikanban,

Is the VPUDEC usage, you can tell mendel OS to change the pipeline to v4l2h264dec for better perfomance.
