PixmapRecorder

Video file encoder

Feed in video data frame by frame to encode video files in one of the various formats supported by FFmpeg.

This is a convenience wrapper for piping pixmaps into FFmpeg. FFmpeg will render an actual video file from the frame data. This uses the CLI version of FFmpeg, no linking is required.

final

class PixmapRecorder : OutputRange!(const(Pixmap)) {

this(double frameRate, File output, string outputFormat, File log, string ffmpegExecutablePath);

}

Constructors

this this(double frameRate, File output, string outputFormat, File log, string ffmpegExecutablePath): Prepares a recorder for encoding a video file into the provided pipe.
this this(double frameRate, string outputPath, File log, string outputFormat, string ffmpegExecutablePath): Prepares a recorder for encoding a video file saved to the specified path.

Members

Aliases

isRecording alias isRecording = isOpen: Determines whether the recorder is active (which implies that an output file is open).
record alias record = put: Supplies the next frame to the video encoder.
startRecording alias startRecording = close: Starts the video encoding process. Launches FFmpeg.
stopRecording alias stopRecording = close: Ends the recording process.

Functions

advancedFFmpegAdditionalOutputArgs void advancedFFmpegAdditionalOutputArgs(string[] args): Advanced users only: Additional command-line arguments to be passed to FFmpeg.
close int close(): Ends the recording process.
isOpen bool isOpen(): Determines whether the recorder is active (which implies that an output file is open).
open void open(Size resolution): Starts the video encoding process. Launches FFmpeg.
put void put(Pixmap frame): Supplies the next frame to the video encoder.
