IC Imaging Control C++



The MediaSampleInfoDataStore object is used to retrieve extended frame information in the form of chunked data blobs.

You can fill the MediaSampleInfoDataStore object by calling its MediaSampleInfoDataStore::update method to retrieve the data from a specific IFrame. Some devices do not deliver extended frame data so this may fail.

After successfully retrieving the data, you can get generic frame information by calling MediaSampleInfoDataStore::findSampleInfo.

The MediaSampleInfoDataStore::findChunk methods retrieve specific chunks. E.g. one specific camera supplies a chunk item which contains the information whether a frame was captured in short or long exposure mode.
