Unable make bmdcapture commit 94b44c4ff0

[glyshko]

Two weeks ago i succeses compiled bmdcapture with SDK 9.1, last commit decklink-ffmpeg - 8a65e71 .
At now when i try compile bmdcapture commit 94b44c4 i see this error:

Hoffie forgot to make his improvements compatible with the newer sdk...

I hope it's fixed and decklink-ffmpeg is compatible with SDK 9.1 and 9.2.
Thanks

I'm terribly sorry that my changes broke the build for you. I've submitted a pull request with a fix for this issue -- the changed code builds with sdk-9.2 for me.

While the code should have been compatible with either old or new SDKs, the detection could not work properly because of changed #include ordering (which is now no longer a problem).

Please wait for Luca to merge the pull request or try using my patch/fork in the meantime.

BTW: Your compiler logs from above also mention problems with libav* -- are you sure you are using a recent enough libav? As far as I remember I did not even touch any libav-related code, so this (second) problem should be unrelated to my changes. Either your environment (regarding libav) changed or your last-working version is even older (before Luca started using newer libav API calls in 6bc9e43) -- or I'm wrong. ;)

Best regards,

Christian

Hello lu-zero, hello hoffie.

I am not quite sure, maybe I am missing something - but this is the only place where I might find some help on this topic. I worked thru your Readme, installed the sdk (9.2), but bmdcapture fails to 'make' with following prompts:

g++ -o bmdcapture bmdcapture.cpp /home/ray/decklink/include/DeckLinkAPIDispatch.cpp -Wno-multichar -I /home/ray/decklink/include -fno-rtti -D__STDC_CONSTANT_MACROS -g -lm -ldl -lpthread pkg-config --libs libavformat
bmdcapture.cpp: In function ‘AVStream* add_audio_stream(AVFormatContext_, CodecID)’:
bmdcapture.cpp:208:38: error: ‘avformat_new_stream’ was not declared in this scope
bmdcapture.cpp: In function ‘AVStream_ add_video_stream(AVFormatContext_, CodecID)’:
bmdcapture.cpp:252:38: error: ‘avformat_new_stream’ was not declared in this scope
make: *_* [bmdcapture] Error 1

I could not find any support-forum or knowledgebase. Might be a mistake to post this here. Does anyone of you know a solution for this problem?

Thanks a lot!

Well, this is really not the right place as it is a different issue and because it is probably not a bug but rather a problem in your build environment
The problem is most likely related to your libav version (also see my previous comment) -- the current code requires libav-0.8 while your version seems to be older and lacks some of the API functions which are used (avformat_new_stream).
Install libav-0.8 and you'll probably be fine.
Also feel free to mail me directly if you need further help.
