, for information with regard to adding cue points to your output FLV file.
Use
, or
to specify the types
of cue points for which the PNG exporter should export PNG images.
sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);
if (sc == ON2_OK)
// generate PNGs for all cue points
sc = Flix2_FilterSetParam(png_exporter_plgn,
FE2_PNGEX_EXPORT_CUE_POINTS, FE2_PNGEX_CP_ALL);

#define FE2_PNGEX_EXPORT_FIRST_FRAME_PNG
Filter parameter for enabling PNG image creation using the first video frame.
This parameter will force the PNG exporter to generate a PNG image from the first video frame in the input
file.
sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);
if (sc == ON2_OK)
// create a PNG image of the first video frame
sc = Flix2_FilterSetParam(png_exporter_plgn,

milliseconds
if this parameter is specified in a call to
sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);
if (sc == ON2_OK)
// generate a PNG every 10 seconds
sc = Flix2_FilterSetParam(png_exporter_plgn,
FE2_PNGEX_EXPORT_INTERVAL, 10000);
