Used to retrieve information about the specified video clip.
Declaration
function AVIInfo2 (AVIFile: string; AVIInfoType: TAVIInfoType): string;
wchar_t *__fastcall AVIInfo2(wchar_t *AVIFile, TAVIInfoType AVIInfoType);
Function AVIInfo2 (AVIFile as string; AVIInfoType as TAVIInfoType) as String
Description
This function returns theTAVIInfoType value as a string for the video clip specified as parameter.
E.g.:
Dim VideoCodec as string
VideoCodec = AVIInfo2 ("myvideoclip.avi", av_VideoCodec)
Dim ClipDuration as string
ClipDuration = AVIInfo2 ("myvideoclip.avi", av_Duration)
Note: if the clip file name does not change, the clip is opened only one time. All the values are read and cached.
Therefore all the subsequent calls to AVIInfo2 with the same file name do not reopen the video clip.
The possible values returned by AVIInfo2 depending on TAVIInfoType are (av_Duration, av_FrameCount, av_VideoWidth, av_VideoHeight, av_VideoFrameRateFps, av_VideoCodec, av_AudioCodec, av_AvgBitRate, av_AudioChannels, av_AudioSamplesPerSec, av_AudioBitsPerSample);
