I have been trying to use the jetson_multimedia_api example 01_video_encode to achieve lossless compression for my pipeline. When I tried the example on my yuv file, without the --elossless option, it works fine and gives me a compressed h264 video as expected. However, with the flag enabled, it crashes with the following trace.
sudo ./video_encode sample.yuv 640 360 H264 sample.h264 --elossless --max-perf --stats

Also, for the command above it was suggested to use the -p high444 profile but that is not recognized. How do I tell the encoding command that the input is a YUV444 file?
I tried using the h265 output format with the --elossless flag (if I recall correctly on Jetpack 4.6.1 it is supported) and it ran without any error.
