SGSetFrameRate
The SGSetFrameRate function allows you to specify a video channel's frame rate for recording.
pascal ComponentResult SGSetFrameRate (SGChannel c,
Fixed frameRate);
c
- Identifies the channel for this operation. You provide your
connection identifier. You connect to a channel component by calling the SGNewChannel or SGNewChannelFromComponent function, discussed on page 5-29 and page 5-30, respectively.
frameRate
- Specifies the desired frame rate. Set this parameter to 0 to select the channel's default frame rate. Typically, this corresponds to the fastest rate that the channel can support.
DESCRIPTION
The SGSetFrameRate function allows you to control a video channel's frame rate. Note that the digitizing hardware may not be able to support the full rate you specify. If you specify too high a rate, the sequence grabber operates at the highest rate that it can support. Note that you may not call this function when you are recording.
RESULT CODES
| paramErr | -50 | Invalid parameter value |
| cantDoThatInCurrentMode | -9402 | Request invalid in current mode |
SEE ALSO
You can retrieve a channel's current frame rate by calling the SGGetFrameRate function, which is described next.
