I raised this issue in a previous thread that unfortunately devolved into multiple directions of discussion.
I'd like to keep this thread focused on this one issue, please.

Back in 2016 this MCC was added to MC 21:

Code: [Select]

21.0.38 (1/18/2016)
9. NEW: Added MCC_PLAYBACK_ENGINE_VIDEO_ZOOM (28038) to set the zoom for a playing video.
28038 MCC_PLAYBACK_ENGINE_VIDEO_ZOOM int nZoomAmount (100 is 1.0)
I have unsuccessful making the 28038 MCC function operate in MC 26. These have been my efforts so far:

First I created a custom resources file Resource.xml located in C:\Program Files\J River\Media Center 26\Data\Custom Resources:

Code: [Select]

<ACCELERATORS>
<!-- Playback engine Zoom custom shortcuts (shared) -->
<Entry TranslateFlags="32" Param="100" Command="28038" Key="Alt;F1"/>
<Entry TranslateFlags="32" Param="130" Command="28038" Key="Alt;F2"/>
<Entry TranslateFlags="32" Param="150" Command="28038" Key="Alt;F3"/>
</ACCELERATORS>
The defined hot keys had no apparent effect.

When that failed to work, I modified the default resources file Resource.xml located in C:\Program Files\J River\Media Center 26\Data\Default Resources.

This also failed to work.
To make sure that it wasn't an issue with a existing key conflict I commented out two existing entries for the + and - keys and substituted my additions for them):

Code: [Select]

    <!-- Global shortcuts -->
    <Entry Key="Ctrl;Shift;F12" Command="25015" Param="1" Global="1" />

    <!-- Playback engine Zoom custom shortcuts (shared) -->
    <!-- <Entry Key="Alt;F1" Command="28038" Param="100" TranslateFlags="32" /> -->
    <Entry Key="+" Command="28038" Param="150" TranslateFlags="32" />
    <Entry Key="-" Command="28038" Param="250" TranslateFlags="32" />

    <!-- Playback engine shortcuts (shared) -->
    <!-- <Entry Key="+" Command="28000" TranslateFlags="32" /> -->
    <Entry Key="I" Command="28000" TranslateFlags="32" />
    <!-- <Entry Key="-" Command="28001" TranslateFlags="32" /> -->
    <Entry Key="O" Command="28001" TranslateFlags="32" />

Again,the defined hot keys had no apparent effect however the + and - keys no longer caused a zoom as expected.

I have exhausted my efforts since I have no access to the code.

So, could we please get a MC guru to check if there was a possible regression or if any other issues that may have disabled or broken the 28038 MCC code function exist?

Thanks (in advance)

I just played a video and fired MCC 28038 of 120 and 50 from the command line and it worked fine.

Not sure if there's anything else I can test?

Thanks.

[Movieman]

Matt - Exactly how did u do that, with a full screen video running?
I forgot to mention: I'm running Red October HQ.

[Matt]

I forgot to mention: I'm running Red October HQ.

Maybe try turning off HQ as a test?

[Movieman]

No difference... 
I and O work to zoom, what am i missing, if anything?  Does 28038 have to be defined anywhere else?
again how did you access a command prompt when in full screen?

[Matt]

Try playing a video and running the launcher:
MC26.exe /MCC 28038,50

Just have a command prompt window open and Alt+Tab to get to it.

Does that work?

[Movieman]

Yes that works

[Matt]

Well that means the command is working.

So you just need to figure out why it's fumbling.  Maybe try just using 0 as the parameter for translation.  You're saying TRANSLATE_FLAG_TARGETS_PLAYBACK_ENGINE but I'm not sure if that's right for this command.

[Movieman]

But I don't understand the numeric values

28038   MCC_PLAYBACK_ENGINE_VIDEO_ZOOM      int nZoomAmount (100 is 1.0) implies an absolute zoom value

Did the 50 make it 50% larger?  It should have set the zoom to 50%

[Matt]

200 is smaller and 50 is bigger.

[Movieman]

Not what I was hoping for.  I expected this option to allow me to establish hot keys for specific values of zoom to use for different aspect ratio source material.

Like 1.85:1 vs 2.20:1 vs 2.55:1.  Put in a specific value and the zoom will change to that value.  These input values are relative to the previous zoom and this doesn't do anything the I and O keys don't already do.

[Matt]

These input values are relative to the previous zoom and this doesn't do anything the I and O keys don't already do.

I don't think that's correct.  Setting a value of 200 _always_ just zooms out by the same amount.  It is not relevant what the current setting is.

I was wondering if we should add a mode for that, but it currently is independent.

[Movieman]

Sucess

1. I had to remove the translate flags from the Resource.xml
2. The required parameter is actually 100 - the desired zoom amount.
3. It does zoom from the baseline of 100.

So we are all good.

Thanks again, I don't think I would have ever figured it out without your Help.

[Matt]

Glad you got it.

You probably will have to adjust the Param= value for your specific setup.

Best to you all in this time of stress.
