@AquilesCanta Hi Santiago, Do i need to provide any more details that could help you?

Sorry for the delay, but I cannot debug the issue just yet. Will try to do next week. There is nothing obvious I can point out, so I will just try to manually diagnose the issue. Feel free to give it a try, if you have some time.

Hi everyone,
I tried to play the media and failed too. I think given link is not valid and RTMP extension fails to connect through RtmpClient with exit code -3 or -4.
Please try this one: rtmp://184.72.239.149/vod/mp4:bigbuckbunny_1500.mp4 though I'm not sure that it is real RTMP format.

@VitalyVPinchuk Hi, Thanks for trying out this issue. But this audio url is valid and its playing well in the FFmpeg Media Player . And also it plays if you open the MBC Radio in Iphone Safari.

Hi,
But still, I think it's not the issue of ExoPlayer. RTMP extension depends on RTMP-Client, which doesn't play this media offhand. Probably you should ask there (https://github.com/ant-media/LibRtmp-Client-for-Android).

@VitalyVPinchuk Thanks for the information. I have opened a issue in LibRtmp. Error in playing RTMP Audio Stream

I can't play rtmp://mbcmediaserver.mbcradio.tv/bestfm/livestream using anything, including VLC and the mentioned FFMpeg Media Player. Are you really sure it's valid? Can you play it using VLC? If it's geo-restricted, have you any idea to which country?

[tspvivek]

@ojw28 Please try opening this http://www.mbcradio.tv/sites/all/themes/mbcradiotv/templates/bestfm.html
link in Iphone Safari browser and Press the play button. Its playing fine. I'm sure its not geo-restricted. My app is already playing this url using FFmpeg Media Player.

I was able to make a little more progress:

• VLC is only able to play the stream if I first manually resolve the address to rtmp://202.123.27.133:1935/bestfm/livestream, and then use that directly. I don't understand enough about DNS to understand why this is the case, but there are lots of red crosses when checking DNS propagation for the address. Any idea if this is relevant?
• Using rtmp://202.123.27.133:1935/bestfm/livestream still doesn't allow playback with ExoPlayer, but it does let it get further before failure. The error changes from RtmpIOException.OPEN_CONNECT to RtmpIOException.OPEN_CONNECT_STREAM.

In any case, this is sufficient to work out that the first failure is related to resolving the address, and that at least VLC is also affected.

I have same issue.
Link test my rtmp:
http://hlstester.com/new-hls-player/?url=rtmp://5a6872aace0ce.streamlock.net/nghevov1//vov1.stream_aac

rtmp://5a6872aace0ce.streamlock.net/nghevov1//vov1.stream_aac -> can play welll but when playing in Exo player with this extension, it can not play.

Same issue still. Any solution yet?

This should be fixed by #6303.
