  • Revision 9afb6700c2 : Adjust q range Skip Q values between the q.0 mode and a real q of 2.0 as these

    4 avril 2013, par Paul Wilkins

    Changed Paths :
     Modify /vp9/common/vp9_quant_common.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_quantize.c



    Adjust q range

    Skip Q values between the q.0 mode and a real q of
    2.0 as these are not valuable from an RD perspective.

    avformat/matroskadec : Fix probing of unknown-length headers

    matroska_probe did not support the case of an unknown-length EBML header
    
at all ; given that libavformat's Matroska muxer used to produce such
    
files in the streaming case, support for them has been added.

  • FFMPEG color range cropped to 15-235 in RGB

    20 décembre 2017, par Some1Else

    I have a series of BMPs (or PNG) images that I want to convert to XVID and MP5 movie formats.

    Encoding works but the resulting movie has a washed out color look to it and the blacks are somehow moved to RGB 16 and the brightest 255 values are moved down to 235. I want the output movie to use the same 0 to 255 colors as the source frames.

    Now there are all sorts of conflicting doco out there for FFMPEG so I am hopinbg someone has an example command line that does what I need. I have tried all sorts of pix_fmt flags but none of them get the output movie in the full color range.

    For XVID

    ffmpeg.exe -framerate 60 -i "D:\SRC%05d.BMP"  -c:v mpeg4 -vtag xvid -qscale 1 -y "D:\OUTPUT.AVI""

    For H265

    ffmpeg.exe -framerate 60 -i "D:\SRC%05d.BMP" -c:v libx265 -x265-params lossless=1 -s 3840x2160 -pix_fmt yuvj420p -an -y "D:\OUTPUT.MP4""

    The yuvj420p is supposed to give the full color range but ffmpeg complains "Incompatible pixel format ’yuvj420p’ for codec ’libx265’, auto-selecting format ’yuv420p’"

    So, are there any FFMPEG gurus out there that can give me the magic switches to get my output movies with black blacks and colors that maintain the original frame files 0-255 RGB values.
