  • Problems compiling ffmpeg on windows using cygwin

    26 mai 2014, par Papajohn000

    I’ve been having a lot of trouble recently compiling ffmpeg on windows. I’m currently using the cgywin terminal to run the code. I’ve tried following many of the most popular tutorials on the web but I can’t seem to get it to work. I’m currently using this tutorial as a guide http://www.roman10.net/how-to-build-ffmpeg-for-android/

    Where I’m at :

    I’ve created a bash script

    #!/bin/bash

    I then followed steps 4-6 of this post Does anyone find this useful ? - Compiling FFMPEG on Windows with Cywin and NDK r5 which consists of

    4 - Open the file 'configure' in the root of the FFMPEG directory in a text editor.
    

    
5 - Comment out lines 2073, 2074 and 2075.
    

    
6 - Below 2075, add the following line:

    After this script runs I get some new files within my ffmpeg folder. They are .config, config(header), config.mak , config.fate. The android folder is never created like it is supposed to. I’m also not sure where the library.mak error is coming from considering that it came with ffmpeg download.

    I’m not sure where this i’m going wrong in all of this. I feel like the fact that I’m using windows will make this build process different.

  • OUTPUT webcam video over rtp

    20 août 2013, par Manjinder Singh Sekhon

    I'm currently trying to stream webcam video from beagleboard black to my laptop and am using this line of code :

    avconv -f video4linux2 -i /dev/video0 -debug -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp ://192.168.1.12:5004

    the program starts working, but after a while it doesn't really do anything.

    from what I can see, the program stops because it can't get any input from webcam. The webcam works when I use a opencv program.(so /dev/video0 definitly works.) Any ideas. I've also tried using ffmpeg, but i get message that I should use avconv.
