Hi there,
I'm trying to encrpyt a mutilicast UDP stream with crypto protocol (AES), here is the command line I use:
ffmpeg -f decklink -channels 2 -format_code Hi50 -draw_bars false -video_input sdi -audio_input embedded -i "DeckLink Quad (4)" -filter_complex "[0:v]setfield=mode=tff,setpts=PTS-STARTPTS,drawtext=x=(main_w-text_w)/2:y=(main_h-text_h)/8:fontfile=C\\:/Windows/fonts/consola.ttf:text='TEST-05':box=1:boxcolor=000000CC:boxborderw=20:fontcolor=yellow:fontsize=48[vout];[0:a]asetpts=PTS-STARTPTS[aout]" -c:v libx264 -flags:v +ildct+ilme -g 25 -profile:v high -level:v 41 -tune:v zerolatency -preset:v veryfast -x264-params "nal_hrd=cbr:interlaced=1:weightp=0" -pix_fmt yuv420p -b:v 10000k -minrate:v 6000k -maxrate:v 10000k -bufsize:v 1000k -c:a libfdk_aac -b:a 256k -ar 48000 -metadata service_provider="service provider" -metadata service_name="service name" -map "[vout]" -map "[aout]" -f mpegts -encryption_key 000102030405060708090A0B0C0D0E0F -encryption_iv 000102030405060708090A0B0C0D0E0F "crypto+udp://239.0.0.5:5000?ttl=1&pkt_size=1316&buffer_size=4096000&localaddr=10.40.2.183" -loglevel verbose
The command line above works flawlessly without the crypto protocol.
I've got an error saying "Crypto: seek not supported for write", I don't know why cause I'm even not trying to seek ...
I did a lot of searches on Google, StackOverflow and ffmpeg trac to find a solution but without success till now.
I also tried with different versions of ffmpeg, still same error.
Is anybody already tried to do this ?
Is this a bug ? Should I create a ticket on trac ?
Here is the full console output (verbose):
