YUV_Tools

This tool converts a YUV from one format to another, even the source and destination have different bit depth and chroma format. It can also align the width and height with user-specified alignment and padding method.

Build

• cd repo
• mkdir build && cd build
• cmake ..

Options

• [-w|--width] pixel width of input YUV
• [-h|--height] pixel height of input YUV
• [-i:format] format of input YUV
• [-o:format] format of output YUV
• [-a|--align] width and height alignment for the output YUV, must be an even number, output YUV will be padded if width or height is not aligned
• [-r|--replicate] padding method, 0 for zero padding, 1 for boundary replication padding
• [-n] number of frames
• [-n:beg] start frame index, 0 to number of frames in YUV file minus 1, inclusive
• [-n:end] end frame index, 0 to number of frames in YUV file minus 1, inclusive, end must >= beg

Example

• Convert a Y410 file to an NV12 one without padding:
  yuv_tools -w 1920 -h 1080 -i:y410 input.y410 -o:nv12 output.nv12
• Convert a Y210 file to an Y410 one with 16 aligned using zero padding:
  yuv_tools -w 1920 -h 1080 -i:y210 input.y210 -o:y410 output.y410 -a 16
• Align an I420 file against 32 using boundary replication padding:
  yuv_tools -w 1920 -h 1080 -i:i420 input.yuv -o:i420 output.yuv -a 32 - r 1
• Extract frame 2 to frame 5 of a P010 file
  yuv_tools -w 1920 -h 1080 -i:p010 input.yuv -o:p010 output.yuv -n:beg 2 -n:end 5
• Convert first 10 frames of a P010 file to NV12
  yuv_tools -w 1920 -h 1080 -i:p010 input.yuv -o:nv12 output.yuv -n 10
• Convert 10 frames of a AYUV file to YUY2, starting from frame 7
  yuv_tools -w 1920 -h 1080 -i:ayuv input.yuv -o:yuy2 output.yuv -n 10 -n:beg 7
