I am getting 16bit monochrome data from a FLIR GigE camera and want to save all 16 bits to a video file for future processing. (Actually it is 12 bit data but stored in 16 bit words (16UC1)).
I am able to convert the images to 8UC1 monochrome or 8UC3 BGR and create a video file using the 'FFV1' codec and the appropriate isColor flag. ('FFV1' codec is included with ffmpeg and is supposedly lossless)
If I try to write the 16UC1 image to the video writer it crashes with the message:
OpenCV(3.4.2) Error: Assertion failed (image.depth() == 0) in cv::`anonymous-namespace'::CvVideoWriter_FFMPEG_proxy::write, file c:\build\3_4_winpack-build-win64-vc15\opencv\modules\videoio\src\cap_ffmpeg.cpp, line 296
Are there codecs that work with more than 8 bit data, or ways to pass 16 bit data to standard codecs?
I'm running out of ideas...
