I'm trying to use the rtsp extension in an android app but I have a problem and I get a black screen without an explicit error.
My video url is rtsp://myserver:port/live/test?t=pippo
Watching streaming server's logs I see that, during the SETUP phase, the exoplayer client send this url rtsp://myserver:port/live/test/trackID=1?t=pippo while trying the same url with VLC during the same phase the streaming server logs rtsp://myserver:port/live/test/trackID=1 (whitout query parameter of the original url)
Is it possible to remove the query parameter in the url sent by exoplayer client for the SETUP session with the streaming server?

I'm using this code

val mediaitem = MediaItem.fromUri(Uri.parse(videoUrl))
val mediaSource = RtspMediaSource.Factory().setForceUseRtpTcp(true).setTimeoutMs(10000)
.createMediaSource(mediaItem)
mediaSource.addEventListener(mainHandler, mediaSourceEventListener)
player?.repeatMode = repatMode
player?.setMediaSource(mediaSource ,true)
player?.prepare()

Thanks for the response

Hello @Darthsandr,

Would you be able to provide the responses to the RTSP Describe message that your server is providing?

Also would you be able to provide a bug reports so we can review the logs? You can either attach them to this github issue or send them to [email protected] using a subject in the format "Issue #11160". Please also update this issue to indicate you've done this.

Hello this is the flow between Exoplayer and our streaming servers.
We have not an error in the player but the screen remains black.

Hi
Thanks for the fix
Actually I'm using these implemenmtations:

implementation 'androidx.core:core-ktx:1.9.0'
implementation 'com.google.android.exoplayer:exoplayer-rtsp:2.18.5'

need I to update the version of these libraries?
