B4J Question I can play rtmp streaming in b4j

jose luis gudino · May 22, 2022

Hi everyone, a question I can play rtmp streaming in b4j
thanks

Magma · May 24, 2022

For B4J - I think Mediaview will be ok...

MediaView - video player

This library includes two custom views: MediaView and MediaViewController. MediaView can play local and remote videos and music. The native JavaFX MediaView doesn't include a controller interface. I've implemented one. You can use it or create your own. Tip: the controller code and layout are...

hi,
thanks for your help.
I have tried to use the following command:

MediaView1.Source = "rtmp://161.97.64.221/test/test":

and it throws me an error:

B4X:

rtmp://161.97.64.221/test/test

are you sure that is a working streaming ?

jose luis gudino · May 24, 2022

let me check, please

jose luis gudino · May 24, 2022

MediaView1.Source = "rtmp://161.97.64.221/adictos/tutorial":

at this moment it is running

a greek local tv station/streaming... that works...now

B4X:

    MediaView1.Source = "https://www.hellasnet.tv/rest.live.hn/trt2/playlist.m3u8"

Sorry for asking... is that a streaming server you are running..?? maybe you must open some ports... first check with a other player... like VLC, Windows Media Player... etc..

Hi, thanks for taking an interest in my topic.

I am using wirecast for transmission.
and I'm transmitting from my computer.
tonight it was off
And from vlc it works correctly.

Magma · May 25, 2022

seems not compatible format ??? / don't understand exactly the error getting...

javafx.scene.media (JavaFX 2.2)

jose luis gudino · May 25, 2022

I will carry out the tests trying with different formats
And I'll post the results here.
greetings

Caused by: java.lang.UnsupportedOperationException: Unsupported protocol "rtmp"

Strange... wait I will search a little more..

Magma · May 25, 2022

a "little" solution... not the best... (you have vlc installed on the pc you want to play the rtmp)

..next post with steps...

jose luis gudino · May 25, 2022

I have seen a solution, but it is necessary to install the vlc player, and I do not see it very convenient since the final application is for my clients

the ideal is to install a standalone application

Magma · May 25, 2022

1st) Download 64bit VLC from https://www.videolan.org

2) Download this library of member: moster67 and any file needed (JAR, all zips, libs, sourcecode of demo)

B4JVlcj (embed VLC MediaPlayer in your program/app)

I am pleased to publish a B4J-wrapper/library of Vlcj (version 3.10.1) which in turn is a Java-wrapper of VLC (VideoLAN). With this wrapper, we can use VLC as a MediaPlayer in B4J. I guess most of you are already familiar with VLC. Its strength is that it plays (local and in streaming) nearly...

3) Edit the source code - of his demo and replace these subs with:

Sub btnPlay_Action

B4X:

Sub btnPlay_Action
    'If MediaFile <> "" Or MediaFile.Length > 0 Then
        StopAndPlayMedia
    'Else
    '    Log("no media file selected")
    'End If
End Sub

sub StopAndPlayMedia

B4X:

Sub StopAndPlayMedia
    If vlc.IsPlaying Then
        vlc.Stop
    End If
    ShowDragButtons(False)
    vlc.Play("rtmp://161.97.64.221/adictos/tutorial")
    vlc.SetVolume(50)
    VolLevel = 50
    
    'Note: you can also play streaming media sources
    'vlc.Play(http://www.storiesinflight.com/js_videosub/jellies.mp4)
    
End Sub

..just hit "Play"...

Thank you!!!!

Why not changing the rtmp protocol to something different... ? HLS maybe... or encoding rtmp to hls... somehow...

jose luis gudino · May 25, 2022

I will see if it is possible to encode it to HLS

jose luis gudino · May 26, 2022

hi.
the solution was to install a library on the server in which the source of the
origin is rtmp and converted to hls, using nginx and ffmpeg for
the broadcast.

From the linux command line:

ffmpeg -i ./video.mp4 -c:v libx264 -preset medium -maxrate 3000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 -f flv rtmp://192.168.1.55/hls/stream

the transmission would be:

http://192.168.1.55:8080/hls/stream.m3u8
