  • libvlc android build with mpeg 4 encoder and h264

    6 juin 2013, par jacob

    I am building libvlc for Android and I enabled sout (--enable-sout) but when I try to add sout transcode option, I get this error :

    cannot find encoder MPEG-4 Video
    
*** Your Libav/FFmpeg installation is crippled. ***
    
*** Please check with your Libav/FFmpeg packager. ***
    
*** This is NOT a VLC media player issue. ***
    
Streaming / Transcoding failed
    
It seems your Libav/FFmpeg (libavcodec) installation lacks the following encoder:
    
MPEG-4 Video.

    How can I add mpeg4 encoder support ?

    Another option is to add a h264 encoder but I don't know how to add that either.

  • Cannot modify AVRational time_base on Android

    31 octobre 2012, par tunght_53

    I have successfully built ffmpeg for Android and recorded several videos. Here is the example code from the library which I used to record the video

    /* put sample parameters */
    
c->bit_rate = 200000;
    
/* resolution must be a multiple of two */
    
c->width = width;
    
c->height = height;
    
/* frames per second */
    
c->time_base= (AVRational){1, 25};
    
c->gop_size = 10; /* emit one intra frame every ten frames */
    
c->max_b_frames=1;
    
c->pix_fmt = PIX_FMT_YUV420P;

    However, my phone is quite a low-end phone so it can only record video with a frame rate of about 8fps. I tried to set c->time_base= (AVRational)1, 8 ; and other values as well but I always receive the error message : "could not open codec". When I turn it back to 25, everything works well.

    Can you please help me with this. Many thanks in advance.

  • Building FFmpeg for Android

    13 juin 2013, par varevarao

    I've spent almost a week on this now, trying to get FFmpeg "Angel"/"Happiness" to build for Android.
    I've tried build scripts from all over the internet to no avail. I got closest was using this. As the author himself says the script doesn't work for newer versions of FFmpeg due to this bug, which has been dismissed on that ticket saying "I found a Makefile that does it." This was dis-heartening, being the only post on all of the vast Google world that was anywhere close to my problem.
    So, question time :

    Is there a way to get around the above bug ? I'm trying to use the newest ffmpeg API, and "Love" is just giving me "undefined reference" errors while trying to use av_encode_video2(), and av_free_frame(). The code I was working on the lines of is at the ffmpeg git repo, under /doc/examples/decoding_encoding.c (the function starting on line 338).

    Update : So they've done away with codec_names.sh in "Angel". Sorry didn't notice that before, but the problem persists in a different avatar now. With every build attempt the compiler throws a certain

    start ndk-building...
    
/home/<user>/android-ndk/build/core/build-binary.mk:41: *** target file `clean&#39; has both : and :: entries.  Stop.

    Say whatnow !?
