I have video files in a .MP4 format. I can play them using
video = 'C0004.MP4';
h = implay(video);
Is there a way to begin playback via the command line? And once playback has started, is there a way to get the current frame number of the movie at a particular instance, or when the video has paused?

Hi Gavin,
You can get the Current frame number when the video is paused as follows:
1. Play the video
fig = implay('Test.avi')
fig =
UnifiedScope with properties:
InstanceNumber: 1
Specification: [1x1 iptscopes.IMPlayScopeCfg]
MessageLog: []
DataSource: [1x1 matlabshared.scopes.source.FileSource]
Visual: [1x1 iptscopes.VideoVisual]
Parent: [1x1 Figure]
2. Pause the video.
3. Get the current frame number
CurrentFrameNumber = fig.DataSource.Controls.CurrentFrame
CurrentFrameNumber =
953
