Using Players

LiveCode allows you to play sound and video within your appication using the player object.

Adding a Player Object

Adding a Player Object

The first thing to do is to add a player object to your stack. Do this by dragging it across from the Tools Palette.

Setting the Filename of the Player

Setting the Filename of the Player

You set the filename property of the player object to tell it which sound or movie file to play.

Open the Property Inspector for the player and click the button next to the Source, this allows you to select an external file to be played.

You can also set the filename property of a player in script, for example:

set the filename of player "sound" to "G:/Documents/Elanor/Projects/Getting Started Lessons/hiscore.m4a"

Using the Player Controller

Using the Player Controller

The controller that appears at the bottom of the player allows the user to start and stop play back(1), control the volume(2) and move to a certain point in the sound file or movie(3,4).

Controlling the Player in Script

Controlling the Player in Script

If you don't want your users to have control of the video, or you prefer not to show the controller and add your own objects to control play back, then you can use LiveCode scripts to control the video.

Open the Property Inspector for the player and turn off the controller. You can then use the following commands and properties to control play back.

start command - Resumes playing a paused movie or sound e.g.

start player "movie"

stop command - Stops a currently playing movie or sound e.g.

stop player "movie"

currentTime property - Specifies the elapsed time in a movie or sound, by setting this you can skip forward or back e.g.

set the currentTime of player "movie" to 12000

Referencing Files on a Server

Referencing Files on a Server

You can also set the filename property of a player to an http URL.

If you specify a URL for a streaming QuickTime movie file, LiveCode displays the movie sequentially as it downloads. Otherwise, LiveCode must download the entire file before you can play it. To pre-fetch a file from the Internet in order to speed up access to it, use the load command before visiting the card that holds the player or image that references the file's URL.

Using Players on iOS

LiveCode players are only supported in desktop applications. If you want to use a player in an iOS application you can use an iosPlayer object, this is a native iOS control that displays a movie. For more information on using iOS players see this lesson.

Hello

I have a player and use it to play quicktime movies.

The code in the program refers to a file ending in ".mov".

The uncompiled and compiled (standalone) versions work fine on my PC with XP.

However the standalone does not seem to play the files when I put the standalone (including the resource folder) on a PC with windows 7.

The file extension (".mov") is not visible as an ending on this platform so I wondered if that might be the problem? If so, what can I do to get around this?

Thanks
Ian

Hi Ian,

you can control the extensions of your files in your "Explorer preferences". Have a look at Tools -> Folder Options... -> View. You should then find a line with a tick box that states: "Hide extensions for known file types". If you untick this, you should see the .mov extensions again.

Making the .mov extension visible will probably not help address the problem you are having, but without more information it is hard for me to make any recommendations on what may be wrong.

You could research if someone else has had a similar issue in our LiveCode community on one of our forums: http://forums.runrev.com/, contact support at support@runrev.com or launch a but report in our quality control centre at quality.runrev.com. We would be very happy to look into the issue if you think something is not working the way you think it should.

Kind Regards,

Hanson

Hi,

I have been trying to get a video player to work but with no success. I have done everything shown above but no result. Can I get some sample code for a simple stack that works so that I can compare with what I am doing to see what is wrong please?

Hi Geoff,

Using player objects on desktop apps doesn't really require any code, you just add a player object, set its filename property to reference the video file you want to play and then use the player controls to start and stop the player.

What type of video file are you trying to play and what platform are you working on?

Kind regards

Elanor
