bmdtools install

Hello All,

New to BlackMagic. I am attempting to install bmdtools, and I am getting the following errors when attempting to run make SDK_PATH=/path/to/the/bmd/include (Of course I am using the actual path).

Im on CentOS 6.5 using Decklink SDK 10.1.4

Anyone else come across this issue, and/or can anyone assist here?

Thanks!

It looks like you are missing the libav libraries (libavcodec, libavformat, libswscale, libavutil) required by the Makefile.

However, it turns out that there are two separate implementations of the libav libraries:

1. libav from http://libav.org/
2. ffmpeg from http://ffmpeg.org/

With libav, I get errors when I try to build bmdtools:

Code: Select all

bmdcapture.cpp: In function ‘int main(int, char**)’:
bmdcapture.cpp:803:64: error: ‘av_dict_parse_string’ was not declared in this scope
make: *** [bmdcapture] Error 1

With ffmpeg, I get warnings - but no errors - when I try to build bmdtools:

Code: Select all

bmdplay.cpp: In member function ‘bool Player::Init(int, int, int)’:
bmdplay.cpp:527:39: warning: format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘long unsigned int’ [-Wformat]
bmdplay.cpp:580:15: warning: ‘AVFrame* avcodec_alloc_frame()’ is deprecated (declared at /usr/include/libavcodec/avcodec.h:3422) [-Wdeprecated-declarations]
bmdplay.cpp:580:35: warning: ‘AVFrame* avcodec_alloc_frame()’ is deprecated (declared at /usr/include/libavcodec/avcodec.h:3422) [-Wdeprecated-declarations]

So I would suggest installing the ffmpeg package on to your system before building bmdtools.
