Description
Examples
View Supported File Formats for Your System
View the list of file formats that VideoReader
supports on your system.
fmts = VideoReader.getFileFormats()
Video File Formats: .avi - AVI File .mj2 - Motion JPEG2000 .ogg - OGG File .ogv - OGG Video
This output is for a specific Linux® system. Your results might differ.
Check if File Format Is Supported
Check whether VideoReader
can read AVI files on the current system.
fmtList = VideoReader.getFileFormats(); if any(ismember({fmtList.Extension},'avi')) disp('VideoReader can read AVI files on this system.'); else disp('VideoReader cannot read AVI files on this system.'); end
VideoReader can read AVI files on this system.
Create Dialog Box to Select Video File
Create a dialog box that allows a user to select a video file interactively.
Get the supported file formats.
formats = VideoReader.getFileFormats()
Video File Formats: .asf - ASF File .avi - AVI File .m4v - MPEG-4 Video .mj2 - Motion JPEG2000 .mov - QuickTime movie .mp4 - MPEG-4 .mpg - MPEG-1 .wmv - Windows Media Video
This output is for a Windows® system. Your results might differ.
Convert the formats
array to a filter
list.
filterSpec = getFilterSpec(formats)
filterSpec = 10×2 cell array {'*.asf;*.avi;*.m4v;*.mj2;*.mov;*.mp4;*.mpg;*.wmv;'} {'All Video Files' } {'*.asf' } {'ASF File (*.asf)' } {'*.avi' } {'AVI File (*.avi)' } {'*.m4v' } {'MPEG-4 Video (*.m4v)' } {'*.mj2' } {'Motion JPEG2000 (*.mj2)' } {'*.mov' } {'QuickTime movie (*.mov)' } {'*.mp4' } {'MPEG-4 (*.mp4)' } {'*.mpg' } {'MPEG-1 (*.mpg)' } {'*.wmv' } {'Windows Media Video (*.wmv)'} {'*.*' } {'All Files (*.*)' }
filterSpec
is a cell array that includes 'All
Video Files'
in the first row, and 'All Files (*.*)'
in
the last row.
Create the dialog box using uigetfile
.
[filename,pathname] = uigetfile(filterSpec);
Output Arguments
formats
— Supported video file formats
array of audiovideo.FileFormatInfo
objects
Supported video file formats, returned as an array of audiovideo.FileFormatInfo
objects
with the following properties.
Extension | File extension. |
Description | Text description of the file format. |
ContainsVideo | Logical value that indicates whether VideoReader can
read video from this format. |
ContainsAudio | Logical value that indicates whether VideoReader can
read audio from this format. |
VideoReader
cannot always read a particular
video file even if getFileFormats
lists its format. For
more information, see Supported Video File Formats.
On Windows and UNIX® systems, the list of file formats
does not always contain all the formats that VideoReader
can
read on your system. getFileFormats
returns a platform-dependent,
static list of formats that VideoReader
can read
on most systems.
