Steps to test: 1. Create h265 test files - mp4 and h265 AnnexB streams: ffmpeg -f lavfi -i testsrc=duration=10:size=640x480:rate=30 -c:v hevc input_h265.mp4 ffmpeg -f lavfi -i testsrc=duration=10:size=640x480:rate=30 -c:v hevc -bsf:v hevc_mp4toannexb input_h265.h265 2. Encrypt and decrypt files. Put appropriate input file name here: input_h265.mp4 or input_h265.h265 ffmpeg -i input_h265.h265 -vcodec copy -acodec copy -encryption_scheme cenc-aes-ctr \ -encryption_key 00000000000000000000000000000000 -encryption_kid 00000000000000000000000000000000 \ encrypted_h265.mp4 ffplay -i encrypted_h265.mp4 -decryption_key 00000000000000000000000000000000 Signed-off-by: Vadym Bezdushnyi <vadim.bezdush@gmail.com> |
