Hi everyone,  
I send an RTMP stream (H.264, AAC) to Wowza server and try to use “Test Player” to check signal.

However, I only can see the video; there is no audio at all.

When using VLC to play rtmp stream from Wowza server, video & audio works well.

Additionally, I record directly this rtmp stream on Wowza server, the content include either video or audio; this file also can play well on VLC.

So, is the problem because of “Test Player”? or other reason?

Thank in advance,

Best regards.

More detail, I using ffprobe to get information from recorded file:

Did you try sending a stream to Engine from a different source or use our mp4 file (Buck Bunny video) to test? If you can get that to work in the player then we know there was an issue with your stream source/encoder file and not the player. Also, are you sending it as a high resolution stream? Try changing the bitrates too just to troubleshoot.

If it continues to not work in our player, but in VLC player, please send us a support ticket so we can view your files and run some tests for you.

I found the problem.

I need to encode AAC at raw format not ADTS.

Thank.
