Classes

AudioCodec

Represents a base class for audio codecs used in video processing.

AudioStreamValidationOptions

Options for validating audio streams during processing.

MediaContainerFormat

Represents a base class for media container file formats used in video processing.

VideoCodec

Represents a base class for video codecs used in video processing.

VideoFpsOptions

Represents options for resampling the frames per second (FPS) of a video during processing.

VideoFrameExtractionProcessingOptions

Specifies the options for processing videos to extract a video frame with a VideoFrameExtractionProcessor.

If IncludeThumbnailVideoStreams is true and there is a video stream marked as a thumbnail stream, the video frame is taken from that stream.

Otherwise, the video frame is taken from the earlier of ImageTimestamp and ImageTimestampFraction if both are specified and in range (this allows specifying options that work well for both long and short videos, e.g., by specifying 5s and 30%, for short videos 5s may be way too far in, it could be the end of the video so it takes 30%, and for long videos 30% could be way too far in, whereas 5s would be better).

The video frame is taken from the first video stream that is most likely to be the main video based on dispositions.

The default format for the extracted video frame is PNG.

The default options result in no video frame extraction options being applied.

Note: If no video frame is able to be extracted, then a FileProcessingException will be thrown when processing.

Note: Does not attempt to remove alpha channels, nor attempt to reduce bit depth to 8; callers can utilize additional image processing if needed for these.
