Here's a test file: https://dl6.webmfile...ny_trailer.webm

For your test file I played it, no video just audio.
I have other .mp4 2k files. I tried to play. No luck. It says "Gtsreamer plugin AV1 decoder not available"
I use latest openpli 9
 
Is uses Google VP8 video, and Vorbis audio. It plays without problems on several boxes here. Including my VU+ Solo 4K.
 
I don't have an Uno 4K SE, but the mediasink is compiled with both VP8 and VP9 support.
 
I think the question is what is in your webm file? As in what codecs were used?

Can you post an example somewhere or a source to get this deviated ‘extension’.

tnx for your reply.

I download from youtube in 2k & 4k resolution. in .WEBM format.

you can get a test file from this wesite. just copy a link from youtube and select webm format 

thanks for your hard work.

is it possible to support  .webm format for video playback files? 

I tested with openatv 7.4 , openbh 5.4 and Egami 10.4 images they all played .webm files without problem, but openpli 9 cannot play .webm files. 

can you please fix that issue?
