building bmdtools for Intensity Pro

PostThu Jul 11, 2013 2:46 am

tried with Mint13-32 bit and Mint15-64 bit - both have libav-tools 8.6

Decklink sdk 9.7.1 samples build fine on 32bit, only signal generator failed on 64 bit

make for bmdtools returns same errors on 32 or 64 bit as follows

~/installs/BlackmagicDeckLinkSDK971/Linux/Samples/bmdtools $ make
g++ -o bmdcapture bmdcapture.cpp ../../include/DeckLinkAPIDispatch.cpp -Wno-multichar -I ../../include -fno-rtti -D__STDC_CONSTANT_MACROS -g -lm -ldl -lpthread `pkg-config --libs libavformat libswscale`
bmdcapture.cpp:194:61: error: use of enum âAVCodecIDâ without previous declaration
bmdcapture.cpp: In function âAVStream* add_audio_stream(AVFormatContext*, int)â:
bmdcapture.cpp:207:21: error: invalid conversion from âintâ to âCodecIDâ [-fpermissive]

bmdcapture.cpp:870:83: error: âAV_CODEC_ID_PCM_S32LEâ was not declared in this scope
make: *** [bmdcapture] Error 1

any help greatly appreciated on above as well as advice if libav-tools 8.6 is recent enough or if I should go to 8.8

TIA

Cheers,

The problem is in the changing ffmpeg/libav API. These changes worked for me (can't figure out how to attach it, so take care with line breaks):

awesome, thanks so much to cwilling

bmdplay doesn't build but changing av_get_exact_bits_per_sample to av_get_bits_per_sample "fixes" that - I don't use bmdplay and am no expert so no clue it that's the right fix but it does let it build - probably another ffmpeg vs libav issue

compressing from the command line is now working outstanding and all sync issues disappeared
