I'm trying to develop a custom receiver application. I used; https://github.com/googlecast/CastMediaPlayerStreamingDRM

My server platform is IIS 7.5, and CORS requirements are satisfied. In the .m3u8 file, there are two items, URI & initial vector.

EXT-X-KEY:METHOD=AES-128,URI="http://MY_SERVER_IP/FILE_NAME.key",IV=0x799a4490f82203e21ea413b1bf66bbf8

I put the license server URL on the custom receiver, but it does not work. I get the messages are media player state : "underflow: true", media element state: "Stalled"

How do I solve it? Thanks for reading my question.

P,ease provide the complete console log.Ali Naddaf
Media Player State: "underflow:true"; Media Host State: "Fatal Error: code = 0"; Media Protocol: "HLS";kslee
I guess the problem is that the custom receiver fails to decrypt AES-128. When I try to play the m3u8 media doesn't contain AES-128, it works.kslee

The license file (key) must be served over https.
