Webm Transcoding - Can not play transcoded stream

[Nguyen_Ha]

I have set up my Wowza server followed this article:

https://www.wowza.com/docs/how-to-transcode-live-streams-to-webm-for-mpeg-dash-playback

The transcoded stream displayed “Active” in Incoming streams panel, but I can’t play it by any player, even test player of Wowza:

Status: source stream or file could not be found

Here is the access log when i try to play by test player

Anybody make it work? Can you give me some advice?

[Nguyen_Ha]

I update some screenshots for detail

I’m not sure that RTMP can work with Webm video but it can’t start my stream on Wowza RTMP player panel

Wowza MPEG-DASH player panel shows me that it can connect to the stream and get some manifests, but no video chunks can display?!

I have tested with Shaka player from this link: http://shaka-player-demo.appspot.com/demo/ and got the same result. Here is the Chome’s developer tool screen

I can see that it can get the video chunks but why doesn’t it play back, anybody give me some hints?

[Nguyen_Ha]

There is no one got this problem? No one has transcoded Webm successfully?

[Jason_Tuchler]

Hello,

The WebM transcode should work. I feel it would be best to open a support case for an Engineer to further review.

Please add your encoder details, OS version, system specs, and the below conf and logs.

[install-dir]/conf

[install-dir]/logs

[install-dir]/transcoder

[install-dir]/manager/logs

If you are not sure how to get this information please see the following tutorial.

Best,
