property SourceFileName: String;
The component gets video from the specified file if DeviceType=rvdtFile.
If FFMpegProperty.UseFFMPEG=True, and FFmpeg is available, the component uses FFmpeg to play this file. In this case, video sound can be read by TRVCamSound component linked to this TRVCamera (and then played or recorded using TRVAudioPlayer component or sent by TRVCamSender component).
Otherwise, it uses DirectX. The system must have a codec for this file installed. If video contains sound, the default audio stream is played on the default audio device.
