Recording

There are two functions to record the stream to file. One version with preview and one without. Please

note that Windows7 does not allow recording to the root drive or in the “Program Files” directory unless

the application is run as administrator.

The functions for recording are shown below. If using S2226_StartPreviewAndRecord or

S2226_StartPreviewAndRecordW, please read the section on preview. Before calling any of these

functions, a valid input must be connected to the 2226 and the configuration settings properly

configured. The 2226 does not support switching inputs while streaming. Do not unplug the input after

recording has started.

• S2226_StartRecordAndPreview, S2226_StartRecordAndPreviewW

• S2226_StopStream

Stream Capture

Stream capture is the process of capturing the encoded H.264 stream to memory. This is done by a

callback mechanism. The callback must not block and should return in a timely manner. If the callback

does no return fast enough, data will be lost and the stream could be corrupted. If a lot of processing

must be done on the data during the callback, it is recommended to use standard software Engineering
