  • error : ‘CODEC_TYPE_AUDIO’ undeclared when make m3u8-segmenter

    28 février 2012, par why

    I want to make m3u8-segmenter for Http Live Stream : https://github.com/johnf/m3u8-segmenter

make: *** [all] Error 1

  • Remove some redundant NULL checks and fix a free on error return.

    3 mars 2012, par Tim Terriberry
    Remove some redundant NULL checks and fix a free on error return.

    ref_frame_data was being allocated with the aligned allocator, but
    
 freed with the normal _ogg_free() function on failure, which
    
 doesn’t work.
    
This would only cause a problem if there was just enough memory to
    
 satisfy the reference frame allocation (just over 4.5 or 9 bytes
    
 per pixel) but not enough for the fragment buffer offets (1/16 or
    
 1/8th byte per pixel).

  • How to resolve OpenCV 2.3.1 compilation error on Ubuntu 11.10 due to FFmpeg [closed]

    14 mars 2012, par Cerin

    compile opencv2.3.1 in ubuntu 11.10

    How do you prepare your environment so you can properly compile OpenCV 2.3.1 on Ubuntu 11.10 ?

    I'm following the OpenCV install guide, but it's instructions are frustratingly complex.

    However, I've distilled it into the following script :

    sudo apt-get install --yes cmake libjpeg62 libjpeg62-dev libtiff4 libtiff4-dev libjasper1 libjasper-dev libpng12-0 libpng12-dev libavformat-dev libswscale-dev openexr zlibc zlib1g zlib1g-dev python2.7-dev libgtk-3-dev gcc g++ libtbb-dev
    
cd /tmp
    
wget --output-document=OpenCV-2.3.1a.tar.bz2 http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.3.1/OpenCV-2.3.1a.tar.bz2/download?use_mirror=iweb
    
tar -xvjf OpenCV-2.3.1a.tar.bz2
    
cd OpenCV-2.3.1
    
mkdir release
    
cd release
    
time cmake -D WITH_TBB=ON -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
    
time make

    Everything runs succesfully, except of course for make which exits with the error :
