B4A Library Play RTSP easily

This library wrap by Biswagit,
Thank you Mr. Biswagit.
Now I want to share it in B4x for help to all B4x developers.
Download library from here

I can't get this to work.

I click "Start" and nothing happens - no video, no error displayed or in event log.

If I enter the exact same URL into VLC, the video plays fine.

PS. I don't know if this helps but after compiling this example, there is only the permission of "android.permission.FOREGROUND_SERVICE" - there are no permissions requested for network access which I though was strange because this app needs to access the network.

Hi:

It's working for me, thanks for sharing¡¡
I will donate to Biswagit as soon as possible¡¡

 

[JohnC]

OK, I added "AddPermission("android.permission.INTERNET")" to the manifest.

Now the video plays, but no audio

 

[JohnC]

If possible, it would be great if this wrapper could support a volume property, so that the user could control the volume.

What is your link?
Do you set username and password correctly?

Using VLC, after a small delay, both video and audio work fine.

But using this sample only the video works - I do not get sound.

But using this sample only the video works - I do not get sound.

Tested with VLC on my computer. I get sound at the beginning of the stream for one second, then it's mute despite codec-info in VLC indicating there is an audio stream included. Perhaps something wrong with the stream?
Same thing with Vitamio5 (video OK but no sound)

 

[JohnC]

When I run the latest VLC on my android phone with cell connection, the screen starts black for about 8 seconds, then the video and audio start and both keep streaming OK long term (audio or video does not kick out).

When I test the Vitamio5 with cell connection, always stays black and no audio ("vvit5_Prepared" event never happens).
When I test the Vitamio5 with local network connection (encode is on the local network), video appears in a few seconds, but no audio.

When I test with the wrapper in this thread with cell connection, video starts almost immediately, but never any audio.
When I test with the wrapper in this thread with local network (encode is on the local network), video starts almost immediately, but never any audio.

Do you have a testing link that has sound?
I want to give link to Biswagit for testing it

 

[JohnC]

I re-enabled the link in post #8.

If you use the latest version of VLC for android and enter that URL into VLC, after about 5 seconds the video AND audio will play.

But for some reason, the audio does not work with this wrapper.

Sending this link to Biswagit would be greatly appreciated.

Thank you, I hope Biswagit can solve it

Same error.
Solution: select ExoPlayer in libraries.

 

[mehdipass]

Solution: select ExoPlayer in libraries.

ExoPlayer in b4a not support rtsp link.

 

[German Buchmuller]

ExoPlayer in b4a not support rtsp link.

No. I didn't say ExoPlayer supports RTSP. What I said is to select ExoPlayer Library in the IDE to solve the following error

java.lang.ClassNotFoundException: com.google.devtools.build.android.desugar.runtime.ThrowableExtension

while using RTSP Library.
In other words, RTSP Library requires ExoPlayer Library to be selected.

oh, thank you very much.
