RTSP missing attribute fmtp #901

Open coocoricodev opened 6 months ago

coocoricodev commented 6 months ago

Hello,

I'm attempting to play a camera stream using ExoPlayer, but I'm encountering an issue.

My code is very simple :

    val mediaSource: MediaSource = RtspMediaSource.Factory()
        .setDebugLoggingEnabled(true)
        .createMediaSource(MediaItem.fromUri("rtsp://user:password@camera.domain.com:14500"))

    val exoPlayer = ExoPlayer.Builder(context).build()
    exoPlayer.setMediaSource(mediaSource)
    exoPlayer.prepare()
    exoPlayer.playWhenReady = true

I'm facing the same problem with two models of Hikvision cameras. The connection and authentication work well, but the DESCRIBE operation fails due to the absence of the "fmtp" attribute. I've tested other apps using ExoPlayer, and the stream functions correctly. So I believe I may have missed something in my configuration.

Could you help me to understand the issue ? I'm not sure fmtp attributes is mandatory. I tried to look the other app RTSP frame using Wireshark and the stream works well with the same frame so without fmtp.

Works well on other video players like vlc-android etc. Why do you only need the fmtp attribute in exoplayer? I don't understand.
