    This code use for live streaming for send data using RTMP Wrapper.
    Not write in Socket properly because every 5 second to generate different file output file.

    This is proper way ?

    I have no idea how to get NSData in proper way.

    Please help me .

  • Compiling ffmpeg for iOS and gas-preprocessor.pl

    16 mai 2017, par user500

    I want to compile ffmpeg for iOS. I did it a few times before. But now I’m on clean new Mavericks and on configure I’m always getting

    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    
GNU assembler not found, install gas-preprocessor
    

    
If you think configure made a mistake, make sure you are using the latest
    
version from Git.  If the latest version fails, report the problem to the
    
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    
Include the log file "config.log" produced by configure as this will help
    
solving the problem.

    I have current Xcode installed. Also brews. And current gas-preprocessor.pl (https://github.com/yuvi/gas-preprocessor) in usr/bin and also in usr/local/bin.

    On perl /usr/bin/gas-preprocessor.pl gcc I’m getting Unrecognized input filetype at /usr/bin/gas-preprocessor.pl line 33.

    This config works :

  • Cannot stream video from VLC docker

    I have Dockerfile :

    And then run :

    I get error :

    I mention that I'm using cvlc and I can't stream that mkv file.

    


    I tried as well --sout '#transcode{scodec=none}:http{mux=ffmpeg{mux=flv},dst=:8787/}' but same errors.

    


    How can I solve it ?
