Decklink mini recorder and bmdcapture modes list

[c0ntact0]

Hi!

The Decklink mini recorder don't have outputs and because of that the modes list fail to load with the IID_IDeckLinkOutput interface. Must be used the IID_IDeckLinkInput interface to this card work.

Something like this fix the code:

// Query the DeckLink for its configuration interface

// Test input modes
result = deckLink->QueryInterface(IID_IDeckLinkInput,
                                  (void **)&deckLinkOutput);
  if (result != S_OK) {
   fprintf(stderr,"Could not obtain the IDeckLinkInput interface - result = %08x\n",result);

   // Input modes test failed lets try the output modes test
   result = deckLink->QueryInterface(IID_IDeckLinkOutput,
                                  (void **)&deckLinkOutput);

   if (result != S_OK) {
    fprintf(stderr,"Could not obtain the IDeckLinkOutput interface - result = %08x\n",
        result);
goto bail;
  } else {
fprintf(stderr,"This card have video output(s) but not have video input(s). You can not use this card with the bmdcapture software.\n");
    goto bail;
  }
}

Hi Luca.

The patch follows in attach. This patch it's made for the mac branch (sorry for that, I don't test it linux, just in MacOS Lion) and add the missing inputs (optical and S-Video) for the mac branch, add the print_capabilities function to list the supported video input connections and add the query to the IDeckLinkInput interface. The code query the output first, if fails query the input.

Hi c0ntact0, I've successfully applied your patch, but I can't capture 1080P video signal via SDI input. Here is my setup [Video Source] -----SDI---->[Decklink mini recorder]----->[BMDCapture]--->[AVCONV].

Capture video and audio to a file. Raw video and audio can be sent to a pipe to avconv or vlc e.g.:

bmdcapture -m 2 -A 1 -V 1 -F nut -f pipe:1

Thanks.

"At least one output file must be specified"

You must specify a output to avconv (a file or other, i.e. a pipe to avplay). And you may want to convert to some output codec i.e.:

bmdcapture -C 0 -m 5 -A 2 -V 4 -F nut -f pipe:1 | avconv -i - -vcodec mpeg2video -vb 50M -acodec copy output_file.mov

Run "man avconv" in the terminal for mode details.

If you want to capture the raw video from the Decklink to test bmdcapture alone, you can do:

bmdcapture -C 0 -m 5 -A 2 -V 4 -F raw -f output_file.raw

Hi c0ntact0, I think you didn't see this "Frame received (#1) - No input signal detected - Frames dropped 1 - Total dropped 1" Do you have any idea? Thanks.

[madhawa]

Hi c0ntact0, I've replace the card (Decklink mini recorder) with a new mini recorder card; everything works fine :) Thanks.

[PatNarciso]

madhawa: just to clarify, do you believe the issues you were having were related to the "Decklink Mini Recorder" Card?

[madhawa]

HI, No. It was a defective Decklink Mini card. I've replace the card & everything works fine.

Is bmdcapture working with the UltraStudio Mini Recorder? I can't get any further than: Could not obtain the IDeckLinkConfiguration interface - result = 80000004
