  • Building FFmpeg for android to run command line args

    11 septembre 2012, par Zargoon

    I am trying to build the FFmpeg library to use in my android app with the NDK. The reason for this is because I am using the native video capture feature in android because I really don't want to write my own video recorder. However, the native video capture only allows for either high-quality encoding, or low quality encoding. I want something in between, and I believe that the solution is to use the FFmpeg library to re-encode the high quality video to be lighter.

    So far I have been able to build the FFmpeg library according to this guide : http://www.roman10.net/how-to-build-ffmpeg-for-android/ and which a few tweaks I have been able to get it to work.

    However, everything that I've found seems to be about writing your own encoder, which seems like overkill to me. All that I really want to do is send a string in command line format to the main() function of FFmpeg and re-encode my video. However, I can't seem to figure out how I build FFmpeg to give me access to the main method. I found this post : Compile ffmpeg.c and call its main() via JNI which links to a project doing what I want more of less, but for the life of me I cannot figure out what is going on. It also seems like he is compiling more than I want, and I would really like to keep my application as light weight as possible.

    Some additional direction would be extremely helpful. Thank you.

  • FFMPEG : Redirecting Matroska muxed data to socket

    14 août 2016, par Parth Shah

    I am using FFMPEG library to mux H.264 and AAC frames to Matroska (.mkv) file. I can do that both using command line and C program.

    Now, instead of writing the muxed matroska data in to file I want to write these muxed data directly on to socket or pipe. My actual goal is to write a C program that send muxed data to socket and server will receive this muxed data.

    I tried using protocol tcp. They are working with the matroska format.
    So, My C program is able to send muxed data successfully over socket and server is able to receive this muxed data.

    But when I apply ffprobe command over the received file, I am getting duration and bitrate field N/A. and when I tried to play this file with vlc i am unable to seek the file and getting garbage duration.

    Below the output of the ffprobe.
