  • DCT coefficients and MV extraction in ffmpeg Mpeg-4 encoding

    30 juin 2017, par Giacomo Calvigioni

    I’m using ffmpeg and libx264 to encode a video and I want to extract the DCT coefficients and motion vector of each frame during the encoding process.

    What is the best way to do this ?

    I read in the ffmpeg manual that is possible to use the debug mode with some flags to extract these values. I tried ffmpeg -debug dct_coeff to output the dct coefficients but this option doesn’t work for me ; is it deprecated or related to a specific ffmpeg version ?

    Another option would be to modify and recompile ffmpeg source code but I don’t know in which part of the code DCT and MV are calculated.

    Any help with the debug mode or code modification suggestions would be appreciated.

  • configure : Remove dcbzl check for e500v1 and e500v2 architectures

    configure : Remove dcbzl check for e500v1 and e500v2 architectures

    The DCBZL instruction is not available for the e500v1 and e500v2
    
architectures, but may still be recognized by the toolchain, so we
    
need to explicitly disable it for these architectures.
