Streaming a file[MOV/MXF/MP4] through Decklink API

We have an mxf file which needs to be streamed/played out to SDI. Through DeckLinkAPI, how can we do it. we saw methods like createVideoFrame and startScheduledvideoFrame but couldn't find how to provide any source/input (say any file such as mp4, mxf, mov).

Thanks in advance.

Hi Anil,

The DeckLink SDK includes only the mechanisms to output ( & capture) a video signal, it does not include any codecs nor container formats.

To achieve your goal, you will need to integrate a decoder for your input file, and provide the raw video frame data to the SDK (Via the IDeckLinkVideoFrame interface).

See SDK Manual section "2.4.2 Playback" for a description of the interfaces needed to perform a playback operation.

Hope that helps,

Hi Anil,

You may want to look at higher-level access to the Decklink cards - ffmpeg or Gstreamer can both output to the cards and have elements for file handling, de-multiplexing and decoding. This approach may better suit your needs.
