i.mx8mq-evk Android Q10.0.0_1.0.0 with udp streaming

[johnke]

I have tested on   Android Q10.0.0_1.0.0 Documentationbut the streaming via udp failed.

Where can I refer to the function of Streaming in the document?

The log shows:

Hi John

i.MX8M has not hardware encoder as described in

i.mx8M EVK board encoder and decoder 

some streaming examples can be found in
