i.mx8mq-evk IPTV function with udp streaming

johnke — Wed, 08 Apr 2020 03:25:02 GMT

I followed 'i.MX_Android_Extended_Codec_Release_Notes' to verify IPTV with udp protocol.
It's working on I.MX8mq EVK and able to display udp streaming.On I.MX8mq EVK, I use Android P9.0.0_1.0.0 and HDMI-OUT to display.
But during playback, the video will have the problem of broken screen and not smooth.

I'm also to display on I.MX6q development board with android or other PC with Windows OS to eliminate network environment problems.When playing on these devices, there is no broken or not smooth.

Any suggestions please let me know, Thanks.

Hi john

Android P9.0.0_1.0.0 is based on quite old L4.14.78-1.0.0_ga release

as described in Android P9.0.0_1.0.0 Documentation

May be recommended to try latest Android Q10.0.0_1.0.0 Documentation

which based on L4.19.35_1.1.0 release.and has much improvements.

Best regards
igor

Hi Igor,

I have tested on 'Android_Q10.0.0_1.0.0' but the streaming via udp still failed.

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

The log shows:
