  • Ffmpeg lose streams while using -map 0

    27 mars 2016, par Ngoral

    I had a strange issue using ffmpeg on Ubuntu 14.04.
    I run a command

    ffmpeg -i output2.avi -c:v h264 -minrate 2000k -maxrate 5000k -bufsize 2000k -profile:v high -level:v 4 -coder 1 -s 640x360 -bf 0 -pix_fmt yuv420p -r 25 -g 25 -c:a aac -ar 48k -b:a 321k -map 0 -y outpu.mp4

    It provides such a usual output in console (already with -loglevel verbose) :

    it seems like it outputs all 3 audiostreams, but then i do

    ffmpeg -loglevel verbose -i outpu.mp4

    What’s wrong with it ?
    It works fine on my Win machine, on virtual machine with Ubuntu on it, but as ran on real Ubuntu it behaves like this. Do you have any ideas ?

  • H264 Encoding - Could not play video using VLC Player

    31 mars 2016, par bot1131357

    I am have trouble encoding an H264 video correctly using FFmpeg libav. I could not play the encoded video in VLC media player, and although I could play the video on MPC-HC the time shows 00:00/00:00. Clearly I’m missing something.

    The Media info from MPC-HC shows this :

    I noticed something odd in the above info :
    - The frame rate is 20.833 fps, instead of the specified 10 fps.
    - Duration of 2s 400ms did not seem right either, since the video played for more than 4s.

    Also, (AVFrame* picture)->pict_type is always set to AV_PICTURE_TYPE_NONE. I don’t think this is normal.

    The library that I’m using is ffmpeg-20160219-git-98a0053-win32-dev. I would really really appreciate if you could help me out of this confusion.

  • Merging two audio files in Android using FFMPEG

    3 août 2016, par Jeremy

    I’m working on an application that takes two audio files, and merges them into the respected channels. The way they are being equalized are not as good as I had hoped, So I want to adjust the volume of each file during the mixing phase. I’ve seen a couple of examples online, like this, this, and [this][3].. but none of them are working for me. Can someone direct me in the right direction with this ? Much appreciation !

    I am using this library to execute : https://github.com/WritingMinds/ffmpeg-android-java

    Here is my code (EDIT)

    String files = "-i " + mVoiceFile.getAbsolutePath() + " -i " + mBeatFile.getAbsolutePath();
    String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2][a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0code>

    enter code here

    and here are my errors from running.
