Constructor & Destructor Documentation

org.sleuthkit.autopsy.contentviewers.GstVideoPanel.GstVideoPanel ( )

Creates new form MediaViewVideoPanel

Definition at line 97 of file GstVideoPanel.java.

Member Function Documentation

List<VideoFrame> org.sleuthkit.autopsy.corecomponents.FrameCapture.captureFrames	(	File	file,
		int	numFrames
	)		throws Exception

inherited

Parameters

file	the video file to use
numFrames	the number of frames to capture. Note that the actual number of frames returned may be less than this number. Specifically, this may happen if the video is very short.

Returns: a list of VideoFrames representing the captured frames

List<VideoFrame> org.sleuthkit.autopsy.contentviewers.GstVideoPanel.captureFrames	(	java.io.File	file,
		int	numFrames
	)		throws Exception

Parameters

file	a video file from which to capture frames
numFrames	the number of frames to capture. These frames will be captured at successive intervals given by durationOfVideo/numFrames. If this frame interval is less than MIN_FRAME_INTERVAL_MILLIS, then only one frame will be captured and returned.

Returns: a List of VideoFrames representing the captured frames.

boolean org.sleuthkit.autopsy.contentviewers.MediaViewVideoPanel.isSupported ( AbstractFile file )

inherited

Although it seems too restrictive, requiring both a supported extension and a supported MIME type prevents two undesirable behaviors:

1) Until AUT-1766 and AUT-1801 are fixed, we incorrectly identify all iff files as audio/aiff. This means that if this panel went with the looser 'mime type OR extension' criteria we use for images, then this panel would attempt (and fail) to display all iff files, even non audio ones.

2) The looser criteria means we are less confident about the files we are potentialy sending to GStreamer on 32bit jvms. We are less comfortable with the error handling for GStreamer, and don't want to send it files which might cause it trouble.
