Editing Video Effects panel on VLC for Mac - objective-c

Ok so this question is actually in two parts.
I coded a video filter for VLC and I would like to add a control to the Video Effects panel on the OS X UI. So far I've been able to link my plugin the the UI by hijacking one of the existing controls, but this isn't ideal.
Now, if I open up the Xcode project (I'm running Xcode 6.3.1) and try to open the VideoEffect.xib file, I get the following error:
I tried to google this but it sounds like the only alternative would be to play archaeologist and dig up an old copy of Xcode 3. Is there any other way to be able to open this file and edit it somehow? I tried to look at the XML code but if I started to change that I'd do more damage than good.
The second thing I'd like to do is sending back values from the effect module to the UI. At the moment (by hijacking one of the existing sliders), all I can do is read a value from the panel with
config_ChainParse(p_filter, FILTER_PREFIX, ppsz_filter_options, p_filter->p_cfg);
p_filter->p_sys->i_factor = var_CreateGetIntegerCommand(p_filter, FILTER_PREFIX "factor");
and then, inside the callback function:
p_sys->i_factor = VLC_CLIP( newval.i_int, 0, 255 );
However, I haven't been able to write back the value. I'd like the filter to set p_sys->i_factor to a random value at start. This works (using var_SetInteger()), but it isn't reflected in the position of the slider in the Video Effect panel. I suspect I need to hack a bit deeper for that. Any ideas?

Regarding your first question with the xib-file. Consider downloading and using our forthcoming 3.0 code from git://git.videolan.org/vlc.git - it allows editing of said file without Xcode 3.
Regarding your second question, why would you want your video filter to interfere with the UI? This is not how the architecture of VLC works and there is no correct way to do it at this point. You would need to edit the core to do another global variable callback to ask the UI to reload the presented filter configuration.
Perhaps, if you give details about what your filter does and what you want to achieve, we find a more supported way :)

Chromium; how to get rid of the black circular X button in fullscreen mode?

In Chromium version 72.0.3626.121 the button to leave the fullscreen mode could be disabled by using the enable-experimental-fullscreen-exit-ui flag. In version 86.0.4240.193, this flag is no longer available.
Does somebody know how to disable this button?
I'm using the following options to start Chromium.
"chrome.exe" --no-default-browser-check --DisableSplashScreen=true --disable-infobars --overscroll-history-navigation=0 --js-flags="--expose-gc" --incognito --start-fullscreen
Adding the --kiosk option disables the button, but it also changes the behavior of the browser, which I don't want.
Appologisied if I'm wrong, and I do not propose this as a proper answer to your question, but this is what I think.
It might be possible that the only way to achieve what you want is to rebuild the browser from the source. For example, I wanted my bookmark UI to show a list bigger than few last items, was thinking this could be tweaked by a plugin or config, but it turns out it's a hardcoded const variable in the source code. An extension could use a different bookmarker to replace the bundled one. However, nothing can change that const value except changing it in the code and recompiling the browser.
Without knowing much internals it feels to me the X is there on purpose as safety, not to allow somebody to take advantage of less tech-savvy users (imagine a Windows login screen made in HTML to steal users credentials). Therefore I think very likely you will not be able to do what you want easily. A lot of the experiments and features get removed from the browser, remember the vertical-tabs were there for few versions as a hidden command-line argument, but then that got removed too.

Displaying Webpages From RSS Feed in iOS Xcode

Currently, I have an RSS Feed Reader in a UITableView within a Navigation Control. I would like to click on the links and Open up a formatted page (containing all of the information from the website formatted for the iOS screen). I'm not sure if I should do this using the RSS data and a UITextView? I'm currently attempting to use UITextView in hopes that I can separate the information (title, author, body) without anything looking promising. I want to be able to move around the data and format it to my liking in the actual application itself. I read around and noted that you can include HTML and custom CSS. Would this be the way to go? I'm not quite sure how to tackle this. I want the page that opens up to be entirely scrollable (Like the IGN application or Slashgear application). Many apps for websites utilize this (and I am a bit new to this). How do they go about this? I also want to note, at some point I will like to cache the data so it may load what is already loaded without being connected to the internet. Does anyone have any ideas?
Edit:
Ok, I believe I found the correct path to go down from playing around and a lot of googling (nothing directly says what a decent way of doing this is). My particular way as of now is the route of a UIScrollView in general. Now the part I don't understand is how to divide up the long text into 'pages' for scrolling (and I am using the paging feature. This situation has led me into this question: How To Separate Strings For UIScrollView/UITextView based on the size of the frame

I cannot get a QTCaptureSession to Capture when in a Terminal Application

I've got a terminal application that needs to take a webcam picture and then perform some processing on it. I'm having trouble getting it to initialize. There's a fairly complete demo with an app called MyRecorder in the Apple docs that uses QTKit, which I was able to make work fine. I was also able to modify it to grab a single frame instead of a stream.
When I move this to a terminal application, the startRunning of the QTCaptureSession command simply does nothing. There are no errors, and everything reports as successful, but my webcam doesn't light up, and no frames are captured.
Any idea what's going on here? Are there any kind of security restrictions, or other kinds of restrictions that would prevent the QTCaptureSession from working?
So switching to AVFoundation solved my problem. I'm still not certain what the issue is, but for now using AVFoundation seems like the way to go since it was designed to replace QtKit anyways.

Very confused by a binding issue between a Cocoa app and a Movie Loader patch in Quartz Composer

I've been programming for a while, but just recently decided to start developing for Mac OS X. I feel like I've come to grips with the basics of Objective-C and Cocoa development over the past week. I'm planning on making graphics apps, and as such am currently in the process of learning how to control Quartz compositions through a Cocoa app. I went through the tutorial that apple offers (with the Mac Engravings composition), and was able to create that just fine. In order to make sure that I truly understood what I learned, I decided to create my own composition and link it to a slightly more complicated Cocoa application.
Essentially, I have a composition that loads a movie or image through a Movie Loader patch, at which point it applies various filters to the frames before outputting it. In my Cocoa app, I've written code (or rather copied and pasted from other apple examples) that lets a user pick a file using an NSOpenPanel object. The filepath of the file they pick gets placed in a text-box that I placed in the app's window using Interface Builder. I binded the value of said text-box to the "Movie_Location" key in my composition, which is a published input in the Movie Loader patch that I'm using. However, no matter what I do, movies and images aren't loaded into this composition no matter what I try. The only thing that gets displayed is the default image that I have saved in that input from Quartz Composer (or nothing if I leave it blank before publishing).
I've added a Clear Color patch to the composition and binded that to a colorwell in my UI, and that successfully changes the color in my display, so I know that the composition and my Cocoa app are communicating. I've spent numerous hours at this point trying to figure out what's going on, and I've just about given up. Does the Movie Loader have any weird behaviors that I'm not aware of, or is there something obvious that I seem to be missing? I'd really appreciate any help or advice from anybody.
Thanks for reading through this...
Best,
Sami
There are two things I can think of as reasons why it is doing this:
The file path isn't formatted incorrectly. Try checking backslashes, colons, etc.
The box isn't updating the value. Try literally clicking in the text field and hitting enter.
That's all I can think of without seeing your quartz composition and/or code.
EDIT:
Check the other continuous box, in the general properties.
I figured this out yesterday. spudwaffle's second idea is what was going on. If I were to type a filepath in and hit enter, it would work just fine. I got this to work properly by just removing the bind and instead using the setValue:keyInPath: function that a patch controller offers. That said, is there some way to force a text-box to update? I remember seeing a "continuously update" or something like that button within the bind sub-menu in the inspector, but my code didn't work with that checked either.
Thanks to those of you that tried to help me! I really appreciate it.
Best,
Sami

Problems Embedding Video using FCK Editor

I am using FCK Editor 2.6.4 and having problems trying to embed a (non-YouTube) video into a content area.
I found this previous question / post:
[EDIT -- as a new user, I am only able to post one link in this post. The post in question is titled, "Can I embed video using FCK Editor?")
and have investigated all of the proposed solutions, but none of them work properly:
1 -- Using the "Embed Flash" button in the control panel almost works. However, the video I am attempting to add contains a querystring with parameters, like this:
http://static.animoto.com/swf/w.swf?w=swf/vp1&e=1275795594&f=mGQklEgxXKs9vfEIdGnWsA&d=132&m=p&r=w&i=m&ct=Homes%20in%20Eagle%20Creek&cu=http://hometoindy.com/eagle-creek-real-estate.php&options=
and in using the Flash embed tool, it encodes all of the "&" characters to "& amp;", thus breaking them. If it were just for me, I could manually change them back, but clients who use this will not know how to do that.
2 -- I have installed the YouTube video plugin, and it works great... for YouTube. But it cannot be used to embed non-YouTube videos (it automatically changes the URL to YouTube, no matter what).
3 -- I have installed the EmbedMovies plugin, but it throws a javascript error when attempting to add a video file (such as the above) to a page. (The EmbedMovies plugin page on SourceForge says it has been updated for FCK Editor 2.6, but it does not work.)
4 -- Pasting directly into the editor window (of course) does not work. The only way I've been able to make this work is by pasting into the Source panel, and this is not a good option for clients who are not familiar with HTML.
So, is there a good, working plugin for FCK editor that will allow me to quickly and easily embed a video such as the one above into a content area? I don't need to be able to see or preview it in the editor window; I just need it to work when the page is loaded on the front end.
Thanks!
Given the question you found, and scarcity of answers to that, chances are that the plugin you want does not exist.
If your videos are actually from one, though non-standard, source, I can only repeat my advice from that topic - write your own plugin. I have code of plugin I wrote linked there, it should be easy to change it to accomodate your needs.
