# A simple Dockerfile for building Kvazaar from the git repository
# Example build command when in this directory: docker build -t kvazaar .
#
# Example usage
# Run with an input YUV file and output HEVC binary file
#     docker run -i -a STDIN -a STDOUT kvazaar -i - --input-res=320x240 -o - < testfile_320x240.yuv > out.265
#
# Use libav or ffmpeg to input (almost) any format and convert it to YUV420 for kvazaar, audio is disabled
#
#     RESOLUTION=`avconv -i input.avi 2>&1 | grep Stream | grep -oP ', \K[0-9]+x[0-9]+'`
#     avconv -i input.avi -an -f rawvideo -pix_fmt yuv420p - | docker run -i -a STDIN -a STDOUT kvazaar -i - --wpp --threads=8 --input-res=$RESOLUTION --preset=ultrafast -o - > output.265
#  or 
#     RESOLUTION=`ffmpeg -i input.avi 2>&1 | grep Stream | grep -oP ', \K[0-9]+x[0-9]+'`
#     ffmpeg -i input.avi -an -f rawvideo -pix_fmt yuv420p - | docker run -i -a STDIN -a STDOUT kvazaar -i - --wpp --threads=8 --input-res=$RESOLUTION --preset=ultrafast -o - > output.265
