Get the capabilities of a video overlay scaler
int PgGetScalerCapabilities( PgVideoChannel_t *channel, int format_index, PgScalerCaps_t *vcaps );
ph
This function gets the capabilities of the Video Overlay scaler specified by channel for the video data format specified by format_index. The capabilities are stored in the PgScalerCaps_t structure pointed to by vcaps.
You must set vcaps->size to sizeof(PgScalerCaps_t) before calling this function. |
To find out about all available video data formats, call with increasing values for format_index, starting at zero, until -1 is returned.
