Android Question How to create a RTMP Datasource for Exoplayer?

DonManfred · Oct 13, 2017

Based on https://github.com/google/ExoPlayer/tree/release-v2/extensions/rtmp it should be possible.
The Plugin is last edited a few months ago. Maybe too new for the B4A Exoplayer?

I guess Exoplayer needs an update maybe to have this implemented.

Am i right?

Try the current ExoPlayer wrapper with this aar: https://bintray.com/google/exoplaye...com/google/android/exoplayer/exoplayer/r2.5.3 (rename it to exoplayer.aar).

Are you sure?
The old aar is >900kb while the one you suggest is only about 3kb

KZero · Oct 15, 2017

i tried this 3kb aar and this https://google.bintray.com/exoplayer/com/google/android/exoplayer/exoplayer-core/r2.5.3/ (960kb)
both are crashing when initialize
error log attached

I've updated the library: https://www.b4x.com/android/forum/threads/exoplayer-mediaplayer-videoview-alternative.72652/

It is based on ExoPlayer 2.5.3. It also includes the rtmp extension.

KZero · Oct 16, 2017

Thanks for updating the library

there is no player.createRTMPsource property

1. Download the attached zip and copy the two files to the additional libraries folder. It is a compilation of: https://github.com/ant-media/LibRtmp-Client-for-Android
2. Add these two lines:

B4X:

#AdditionalJar: rtmp-client-3.0.0.aar
#AdditionalJar: rtmp.jar

3. You can play RTMP streams with:

B4X:

player1.CreateUriSource("rtmp://live-fs.wmncdn.net/mbctv1/live1.stream")

Hello @DonManfred , do you have any example working with rtmp protocol?

Can you share here?

Thank you

After the update on ExoPlayer for 1.2.0, this should be work right? Or need to do some procedure?

Please post Error as TEXT instead of uploading an image!

Best is to upload a small project which shows the issue.

Away from that you should have created a new thread for YOUR Issue. Posting to existing threads is a mistake.

B4X:

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
        player1.Initialize("player")
        Dim sources As List
        sources.Initialize
        ' sources.Add(player1.CreateUriSource("https://html5demos.com/assets/dizzy.mp4"))
       
        sources.Add(player1.CreateUriSource("rtmp://live-fs.wmncdn.net/mbctv1/live1.stream"))
        player1.Prepare(player1.CreateListSource(sources))
       
    End If
    Activity.LoadLayout("1")
    SimpleExoPlayerView1.Player = player1
    player1.Play
End Sub

I Tried using the files in post #7 with the Exoplayer wrapper 1.50 and I am getting this error when I try to start the stream:

B4X:

23:11:49: ExoPlayer Error: net.butterflytv.rtmp_client.RtmpClient$RtmpIOException

Sub Player_Error_Sub (Message As String, Exoo As SimpleExoPlayerView)
    Log(DateTime.Time(DateTime.Now) & ": ExoPlayer Error: " & Message)
End Sub

Then I tried just using the "additional aar files" from the ExoPlayer lib page (and removed the #additionalJar statements from post #7):

ExoPlayer - MediaPlayer / VideoView Alternative

Edit: new version: https://www.b4x.com/android/forum/threads/exoplayer-media3-video-player.158204/ ExoPlayer is an open source project that replaces the native MediaPlayer and VideoView types. https://google.github.io/ExoPlayer/ License: Apache 2.0 It supports more media formats, it is more...

And I am getting the same error as Alberto:

I know this is an old thread, but the error shows that you dont have rtmp client jar for net.butterflytv.rtmp_client.
Current exoplayer library is outdated newer version have many improvements for RTmp rtsp functionality.
To fix the error and get the rtmp works with exoplayer you need the rtmpclient aar which is deprecated for newer exoplayer versions. To get the old rtmp client you can download it from this archive
