    I used this library implementation ’com.writingminds:FFmpegAndroid:0.3.2’.
    But i get an error.CANNOT LINK EXECUTABLE "/data/user/0/com.example.newapplication/files/ffmpeg" : "/data/data/com.example.newapplication/files/ffmpeg" has text relocations (https://android.googlesource.com/platform/bionic/+/master/androg-’changes-for-ndk-developers.md#Text-Relocations-Enforced-for-API-level-23)

  • Android camera stream with rtmp has stable 5 second latency

    8 avril 2014, par native1989

    I use ffmpeg with h264 build and javacv on android to stream video from camera to rtmp server.
    I was trying to set all possible video framerates and bitrates, set preset ultrafast, but I still have stable 5 seconds delay.
    If i use android mediarecorder sending mpegts stream with rtmp to server,i have only 2 seconds delay, and if I use -fflags nobuffer options on the client(ffmpeg), the video is appearing immediately.

    I don`t know how in android ffmpeg reduces this latency.
    Here the code :

       recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);
       recorder.setFormat("flv");
       recorder.setFrameRate(frameRate);
       recorder.setVideoBitrate(900*1000);
       recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
       recorder.setVideoOption("preset", "ultrafast");
       recorder.setVideoOption("tune", "zerolatency");
       recorder.setVideoOption("fflags", "nobuffer");
       recorder.setVideoOption("analyzeduration", "0");
  • FFMPEG and Mencoder building screenshot returns 0 size images

    here is the command for video screenshot.
