$ ./dec265 -h
dec265 v1.0.8
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID selecthighest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
