avformat/hlsenc: added HLS encryption
Added HLS encryption with -hls_key_info_file <key_info_file> option. The first line of key_info_file specifies the key URI written to the playlist. The key URL is used to access the encryption key during playback. The second line specifies the path to the key file used to obtain the key during the encryption process. The key file is read as a single packed array of 16 octets in binary format. The optional third line specifies the initialization vector (IV) as a hexadecimal string to be used instead of the segment sequence number (default) for encryption. Changes to key_info_file will result in segment encryption with the new key/IV and an entry in the playlist for the new key URI/IV. Key info file format: <key URI> <key file path> <IV> (optional) Example key URIs: http://server/file.key /path/to/file.key file.key Example key file paths: file.key /path/to/file.key Example IV: 0123456789ABCDEF0123456789ABCDEF Example: ffmpeg -f lavfi -i testsrc -c:v h264 -hls_key_info_file file.keyinfo foo.m3u8 file.keyinfo: http://server/file.key /path/to/file.key 0123456789ABCDEF0123456789ABCDEF Example shell script: BASE_URL=${1:-'.'} openssl rand 16 > file.key echo $BASE_URL/file.key > file.keyinfo echo file.key >> file.keyinfo echo $(openssl rand -hex 16) >> file.keyinfo ffmpeg -f lavfi -re -i testsrc -c:v h264 -hls_flags delete_segments \ -hls_key_info_file file.keyinfo out.m3u8 -- Signed-off-by: Christian Suloway <csuloway@globaleagleent.com> Signed-off-by: Dan Dennedy <dan@dennedy.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
