-- What is it? It started as a quite simple A/V capture based on ffmpeg for Blackmagic Design DeckLink systems. It wasn't and isn't exactly feature complete and had been used as testbed to develop a crude avdevice for ffmpeg and then kept around since it comes handy in many occasions since the avdevice has it's share of issues I don't have time nor will to debug right now. It had been improved thanks to TodoStreaming support to be even more useful paired with a simple player that could be used as example for the output side as well. -- How to build? In order to build it just clone/unpack this on your Sample directory from the DeckLink SDK and then issue "make". If you have ffmpeg and pkg-config installed it will build fine -- How to use? ./bmdcapture -C 1 -m 2 -I 1 -F nut -f pipe:1 | ffmpeg -y -i - <your options here> -I switch from the default (HDMI) source to Analog (both audio and video) -C select the capture device if more than one is present. -F define the container format, I suggest using nut. -f output file name, any libavformat compatible url is supported. ffmpeg -i <source> -f nut - | ./bmdplay -f pipe:0 [TBD] -C select the capture device if more than one is present. -f input file name, any libavformat compatible url is supported. -- Contact You can contact me either at lu_zero@gentoo.org or luca.barbato@axant.it
