Open Source Program to decode Interoperable Master Format (IMF) CPL & OPL into raw audio and video so that we can pipe it into ffmpeg or other processors

This is a WIP! Contains quite some shortcuts and unsecure code (e.g. strcpy). Please use with caution :-)

• take CPL & ASSETMAP as input and output .nut file with r210 10-bit RGB444 and pcms24le
• supports multiple segments with start points and repeat counts
• output can be piped into ffmpeg to produce whatever you want

• only CDCI(YUV422) yet, RGBA coming soon, color problems with YUV444
• audio only wav s24le
• only .nut pipe output
• Not tested yet on content with broadcast framerates such as 23.97
• running it still a bit clumsy (see test.sh)
• might only compile under Ubuntu (nothing else tested)

Ubuntu (WSL)

• apt install libtool, automake, autoconf, cmake
• run sh install-deps.sh
• run make

(see test.sh)

CUR_PATH=$(pwd)
IMF_ENC=${CUR_PATH}/imf_fs

# we need to be in IMF directory for relative path resolve to work (to be fixed)
cd ~/bs500a-dalet-a-ov

CPL=CPL_52a5343e-1184-44b4-86e3-43477636ae69.xml
ASSETMAP=ASSETMAP.xml

# hack
export LD_LIBRARY_PATH=${CUR_PATH}/third_party/openssl/lib

#direct piping
${IMF_ENC} ${CPL} ${ASSETMAP} | ffmpeg -i - -f mp4 -y ~/xpipe.mp4
