    I use python cv2 module to join jpg frames into video, but I can't add audio to it. Is it possible to add audio to video in python without ffmpeg ?

  • nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [on hold]

    28 mai 2014, par user3685074

    I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.

    I followed this guide

    I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
    It seems libx264 isn’t able to do multiple encodings at the same time ?

    I’m using these command :

            exec /usr/local/bin/ffmpeg -i rtmp://localhost/src/$name 
    
        -c:a libfdk_aac -b:a 32k   -c:v libx264 -b:v 128K -f flv rtmp://localhost/hls/$name_low 
    
        -c:a libfdk_aac -b:a 64k   -c:v libx264 -b:v 256K -f flv rtmp://localhost/hls/$name_mid 
    
        -c:a libfdk_aac -b:a 128k  -c:v libx264 -b:v 512K -f flv rtmp://localhost/hls/$name_hi  2>>/tmp/ffmpeg.log;

    this is the output :

  • AndroidBitmap_lockPixels always failing

    20 septembre 2017, par Hadj Ali Oussama

    In my jni module I copy images to bitmaps, which were previously
    passed from my java application.

    I do this using AndroidBitmap_lockPixels/AndroidBitmap_unlockPixels.
    Basically, it renders the image correctly, but there’re strange
    effects : sometimes the application gets stuck, or after some time
    AndroidBitmap_lockPixels always returns -3

    (ANDROID_BITMAP_RESULT_ALLOCATION_FAILED). I guess this is because I
    update these bitmaps not from the GUI thread, isn’t it ?

    If so, what would be correct way to "post" this operation to the GUI

    thread ? Is it possible in jni ?

    Thanks.
