  • avformat/mov : set correct error code in mov_read_custom

    avformat/mov : set correct error code in mov_read_custom

    In function mov_read_custom(), it returns 0 on the path that av_malloc()
    
returns a NULL pointer. 0 indicates success. An error code should be
    
assigned to ret.

  • Call ffmpeg command from matlab (ubuntu 12.04)

    30 novembre 2014, par bigpig245

    I’m trying to call ffmpeg function to get duration of video from matlab. In command line, it returns ok :

    ntrang@ubuntu:~$ ffmpeg -i /home/ntrang/projects/dataset/hmdb51/01_test/a1.avi 2>&amp;1 | sed -n "s/.*Duration: \([^,]*\), .*/\1/p"

    it returns 00:00:18.03

    But when I call it from matlab by system command :

    >> system('ffmpeg -i /home/ntrang/projects/dataset/hmdb51/01_test/a1.avi 2>&amp;1 | sed -n "s/.*Duration: \([^,]*\), .*/\1/p"');

    it returns empty.

    This is my env setting in Matlab

    LD_LIBRARY_PATH='/usr/local/MATLAB/R2013a/sys/os/glnxa64:/usr/local/MATLAB/R2013a/bin/glnxa64:/usr/local/MATLAB/R2013a/extern/lib/glnxa64:/usr/local/MATLAB/R2013a/runtime/glnxa64:/usr/local/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:/usr/local/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64/server:/usr/local/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64'
    

    
PATH='/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.7.0_51/bin'

    I also create symbolic link for libstdc but it can help nothing...

    I have looking around on Internet for solution but not so good so far... What should I do ?

    I’m using Matlab R2013a on Ubuntu 12.04.5 LTS 64bit...

    Thanks in advance.

  • How to encode with ffmpeg PCM to AAC with different sample formats ?

    1er août 2014, par user2212461

    I’m using the following code to encode PCM to AAC using libav. It works with sample_fmt = AV_SAMPLE_FMT_S16 ; and a newer release of liabv. In older versions, only sample_fmt = AV_SAMPLE_FMT_FLT is allowed, but then the decoder always returns 0 (nothing decoded). What in the code do I need to adapt in order to make it work with sample_fmt = AV_SAMPLE_FMT_S16 ? Is sample_fmt the input or output format ?

     avcodec_register_all();
    
 codec = avcodec_find_encoder(CODEC_ID_AAC);
    
 c = avcodec_alloc_context3(codec);
    

    
 c->bit_rate   = 64000;
    
 c->sample_rate= 44100;
    
 c->channels   = 1;
    
 c->frame_size = 86000;
    
 c->sample_fmt = AV_SAMPLE_FMT_FLT;//---> this works with AV_SAMPLE_FMT_S16
    

    
buf = (uint8_t *)malloc(bufSize);
    
audioData = (uint8_t *)malloc(size);
    

    
//fill audioData
    

    
int packetSize = avcodec_encode_audio(c, buf, bufSize, 
    
         (short *)audioData);//------>returns 0 when using AV_SAMPLE_FMT_FLT
