blank on webRTC player

[Eddie Lien]

Hi there,

I used ffmpeg to publish rtmp streams to WCS, flash player worked perfectly but the webRTC player not.
It only shown "PLAYING" with blank screen.
And idea?

ffmpeg output format
Output #0, flv, to 'rtmp://xxx.xxx.xxx.xxx:1935/live/9999':

As I changed audio codec to aac, the problem remained. I also checked the browser console, and no error found.
Help!
