Play video files

jit.playlist

Description

Use jit.playlist to organize sets of video files and play them back. Each video is given a visual representation in a clip where a selection from the entire video file may be choosen. Clips may be dragged within a jit.playlist to re-order them, or they maybe dragged to other jit.playlist objects by using the handle (dot) on the left side of the clip.

Discussion

The jit.playlist object inherits the following attributes from jit.movie. See the jit.movie reference page for descriptions.
colormode
interp
unique
vol
rate
seamless_loopcount (avf engine only)
cache_size (viddll engine only)

Attributes inherited from jit.movie are applied globally to each clip in the playlist. Use the setclip message to override values for specific clips. Global and clip specific attribute values are saved in the playlist's content dictionary and reloaded with the patch. Access these values via the getcontent message.

Arguments

None.

Common Box Attributes

Parameter Attributes

Messages

int

0 stops video playback. A number greater than zero begins playback of the clip with that index. Indices begin counting at 1.

append

Arguments

video file [symbol]
clip number [int]
Add a new video file to the list. First argument specifies the video file. Second (optional) argument specifies the slot number for the clip (starting at 1). If no arguments are listed, clicking the append message in a locked patcher will open a dialog box where you can choose a file to append.

clear

Remove all clips from the playlist. To remove just one clip, right-click on the file you wish to remove in a locked patcher and choose "Remove" from the contextual menu.

(drag)

Create a new jit.playlist object by dragging and dropping a compatible media file into an unlocked patch. To load additional media files into a jit.playlist object, drag the new file onto the jit.playlist UI until a line appears above or below the currently loaded file. To rearrange tracks within jit.playlist, click and drag the handle (dot on the left side) up or down in a locked patch. To replace a currently loaded file, drag the new file over the old one until the entire track is highlighted.

getclipattr

Arguments

clip [int]
attribute [symbol]
The word getclipattr, followed by a clip number and attribute name, will send that attribute's value out the notification (middle) outlet of jit.playlist. This allows you to retrieve an attribute state for a specific clip. You can retrieve read-only attributes (e.g. duration, moviedim, etc.), along with most attributes supported by jit.movie.

getcontent

The word getcontent sends the contents and behavior of all clips out the last outlet of jit.playlist in dictionary format. Connect the last outlet to a dict.view object to see the contents. Please note that most content states will not print their default values. These will only be printed if you explicitly set a value. For the "absolutepath" entry, the full file path for each clip will only be displayed if the file is not in Max's search path. If the file is in Max's search path, only the file name will be displayed.

(mouse)

Use your mouse to play and stop a clip in jit.playlist. Also use it to select small parts of the sample for playback.

next

Plays the next clip loaded in jit.playlist.

pause

Pause playback of the current clip at the current position.

remove

Arguments

clip-number [int]
The word remove, followed by a clip number starting at 1, removes that clip from the list.

resume

Resume playback from the current position if playback has been paused.

selection

Arguments

clip [int]
start [float]
end [float]
Select playback endpoints for a clip using a normalized range (0.0 is the beginning, 1.0 is the end). The first argument specifies which clip (starting at 1). The second argument is the start point for the clip, and the third argument is the end point. If only two arguments are given, they serve as the start and end points for all clips in jit.playlist. If only one argument is given, it serves as the clip number and clears any selection from that clip.

selectionms

Arguments

clip [int]
start [float]
end [float]
Select playback endpoints for a clip in milliseconds. The first argument specifies which clip (starting at 1). The second argument is the start point for the clip, and the third argument is the end point. If only two arguments are given, they serve as the start and end points for all clips in jit.playlist. If only one argument is given, it serves as the end point for all clips in jit.playlist.

setclip

Arguments

clip [int]
attribute [symbol]
value [anything]
jit.movie attributes are available in jit.playlist. To control a specific clip, use the "setclip" message followed by the clip number, attribute name, and value. The message "setclip 2 loop 1" will turn looping on for clip 2.
