  • Using FFMpeg on Android to record to a RTMPS target

    4 mai 2017, par pbdev

    We’re building an Android app that streams video to a Wowza server. When using the RTMP protocol everything works but when we change the protocol to RTMPS (and the port number to 443) the recorder stops after a few frames. We tried both endpoints on a MacBook (streaming the build-in webcam) and that just works well so the endpoints are fine.

    rtmp://my.streamlock.net:1935/app/stream
    
rtmps://my.streamlock.net:443/app/stream

    Here is some of the build.gradle file :

    configurations {
    
    all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
    
}
    

    
dependencies {
    
    compile group: 'org.bytedeco', name: 'javacv', version: '1.3.2'
    
    compile 'org.bytedeco.javacpp-presets:opencv:3.2.0-1.3.2:android-arm'
    
    compile 'org.bytedeco.javacpp-presets:opencv:3.2.0-1.3.2:android-x86'
    
}

    The record method on the FFmpegFrameRecorder instance gets called 30 times per second. After 7 or 8 frames the record method freezes for a minute and then records another 7 or 8 frames. No exceptions are thrown, the app just does ’nothing’. Here are some debugging logs :

  • ffmpeg export multichannel audio -map

    8 avril 2014, par speedyrazor

    I am trying to export all audio channels from a multichannel quicktime file with ffmpeg which has the following audio configuration, but am unsure if the command below is correct. All the files look and play correct in Quicktime player except the L+R_Total.wav which refuses to play in Quicktime player but plays fine in VLC, so not sure if i'm using the wrong command :

    Track 1 - mono
    
Track 2 - mono
    
Track 3 - mono
    
Track 4 - mono
    
Track 5 - mono
    
Track 6 - mono
    
Track 7 - stereo

    I am using :

    /Users/me/Desktop/python/ffmpeg/ffmpeg -i /Users/me/Desktop/test.mov -acodec pcm_s24le -map 0:1 -y Left.wav -acodec pcm_s24le -map 0:2 Right.wav -acodec pcm_s24le -map 0:3 Center.wav -acodec pcm_s24le -map 0:4 LFE.wav -acodec pcm_s24le -map 0:5 Left_Surround.wav -acodec pcm_s24le -map 0:6 Right_Surround.wav -acodec pcm_s24le -map 0:7 Left+Right_Total.wav

    Here is the printout from the terminal :

        MacBook-Pro:~ me$ /Users/me/Desktop/python/ffmpeg/ffmpeg -i /Users/me/Desktop/test.mov -acodec pcm_s24le -map 0:1 -y Left.wav -acodec pcm_s24le -map 0:2 Right.wav -acodec pcm_s24le -map 0:3 Center.wav -acodec pcm_s24le -map 0:4 LFE.wav -acodec pcm_s24le -map 0:5 Left_Surround.wav -acodec pcm_s24le -map 0:6 Right_Surround.wav -acodec pcm_s24le -map 0:7 Left+Right_Total.wav
