Select Aspect ratio in menu

Post by Markus1970 »

Just wondering how I would incorporate two versions of the same video in a menu, it's a concert with the original 4:3 and a cropped 16:9 version.

I have the 4:3 and 16:9 version of the same concert .

I have decided on a menu with a play button and a link to a chapter menu.

So not sure where and how I would implement the control for aspect ratio to be played.

Would I create a menu structure like below.

Main menu
⬇️
Play ➡️ 16:9 version
⬇️
Chapters menu ➡️ 16:9 version
⬇️
Aspect Ratio ➡️ Aspect menu

Aspect Menu
⬇️
4:3 ➡️ Alternative Menu
⬇️
16:9 ➡️ Back to Main menu

Alternative Menu
⬇️
Play ➡️ 4:3 version
⬇️
Chapters menu ➡️ 4:3 version
⬇️
Aspect Ratio ➡️ aspect menu

Thanks in advance

Yes, you can. You can store the selected version in GPR.

I've read the quite informative guide in the downloads section and I can see references to different angles/views which you can assign to the red button etc but is this the same approach to take when you have both the 4:3 and 16:9 version of the same video.

Hi again

Going back to this topic .

What I would like to accomplish is to have the user set the video stream like you can with multiple audio files.
So he can set either 4:3 or 16:9 and also change this in the popup menu also.

You mention GPR but I havnt gota clue how to achieve what I want.

Thanks

So reading the user guide the one with 465 pages https://blu-disc.net/download/user_guid ... ard_mx.pdf there is a section detailing how to change movie angles and the one below changing from a colour to B&W version of the same movie with a UDF action.

In this UDF script it also sets language and subtitles which I don't need as I only have one audio and no subs.

I can modify the script below to have classic and wide-screen and only one audio no subs.

Code: Select all


public void UDF_SwitchBWorColour() {
// switches same movie between black/white or colourized
int PlaylistID;
int SubtitleID;
int AudioID;
long Playtime; // time is returned in nanoseconds
// Step 1. find current movie ID and set language and 
subtitle
PlaylistID = getPlaylistID();
SubtitleID = getCurrentSubID();
AudioID = getCurrentAudioID();
// Step 2. Increment the playlist ID or return to main 
movie
if (PlaylistID == 'Wonderful Life bw')
 {PlaylistID = 'Wonderful Life colour';}
else {PlaylistID = 'Wonderful Life bw';}
// Step 3: find current playing time
Playtime = getMediaTime();
// Step 4: switch movie to new version
playVideoFrom(PlaylistID, Playtime);
// Step 5: audio and subtitle streams the same as before
selectAudioSubtitleStream(PlaylistID, AudioID, SubtitleID, 
true);
}
Would this be correct.

Code: Select all

public void UDF_SwitchAspectRatio() {
// switches same movie between 4x3 and 16x9 Aspect ratios
int PlaylistID;

long Playtime; // time is returned in nanoseconds
// Step 1. find current movie ID
PlaylistID = getPlaylistID();

// Step 2. Increment the playlist ID or return to main
movie
if (PlaylistID == 'Title 4x3')
 {PlaylistID = 'Title 16x9';}
else {PlaylistID = 'Title 4x3';}
// Step 3: find current playing time
Playtime = getMediaTime();
// Step 4: switch movie to new version
playVideoFrom(PlaylistID, Playtime);
}

With the above can you also select the option before you start the movie like you do when choosing audio tracks to play.
Not just a option in the pop menu to change video track .

Also what I'm trying to get my head around is when you normally have a chapter menu it will point to the chapter of the movie.

So for example chapter 1 b&w version of the movie but if I have a udf to choose either b&w or color version of the movie would it overide the chapter pointing to the b&w version.

Two versions - are two separate playlist. Each playlist has its own "current chapter number" and resume time.
If you want to synchronize them you need to do it manually, something like this:
manager.saveResumeTime('Movie color', manager.getMediaTime());
if you run this code in the BW playlist or
manager.saveResumeTime('Movie color', manager.getResumeTimeReg('Movie BW'));
if you run this code in the main menu

When you're switching from one version to another, when returning to the main menu, and a lot of other possible places.

The problem with complex menus and using code is that you need to go deep into the programming and you need to have programming knowledge.
