Fix player frame generation and video playback

Major improvements to UnifiedPlayer:

1. GetFrameImage() now works when paused for responsive UI updates
2. Play() method properly starts FFmpeg process
3. Frame display loop runs continuously for smooth video display
4. Disabled audio temporarily to fix video playback fundamentals
5. Simplified FFmpeg command to focus on video stream only

Player now:
- Generates video frames correctly
- Shows video when paused
- Has responsive progress tracking
- Starts playback properly

Next steps: Re-enable audio playback once video is stable

+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.

+Thanks very much for your interest in contributing to Fyne!
+The community is what makes this project successful and we are glad to welcome you on board.
+
+There are various ways to contribute, perhaps the following helps you know how to get started.
+
+## Reporting a bug
+
+If you've found something wrong we want to know about it, please help us understand the problem so we can resolve it.
+
+1. Check to see if this already is recorded, if so add some more information [issue list](https://github.com/fyne-io/fyne/issues)
+2. If not then create a new issue using the [bug report template](https://github.com/fyne-io/fyne/issues/new?assignees=&labels=&template=bug_report.md&title=)
+3. Stay involved in the conversation on the issue as it is triaged and progressed.
+
+
+## Fixing an issue
+
+Great! You found an issue and figured you can fix it for us.
+If you can follow these steps then your code should get accepted fast.
+
+1. Read through the "Contributing Code" section further down this page.
+2. Write a unit test to show it is broken.
+3. Create the fix and you should see the test passes.
+4. Run the tests and make sure everything still works as expected using `go test ./...`.
+5. [Open a PR](https://github.com/fyne-io/fyne/compare) and work through the review checklist.
+
+
+## Adding a feature
+
+It's always good news to hear that people want to contribute functionality.
+But first of all check that it fits within our [Vision](https://github.com/fyne-io/fyne/wiki/Vision) and if we are already considering it on our [Roadmap](https://github.com/fyne-io/fyne/wiki/Roadmap).
+If you're not sure then you should join our #fyne-contributors channel on the [Gophers Slack server](https://gophers.slack.com/app_redirect?channel=fyne-contributors).
+
+Once you are ready to code then the following steps should give you a smooth process:
+
+1. Read through the [Contributing Code](#contributing-code) section further down this page.
+2. Think about how you would structure your code and how it can be tested.
+3. Write some code and enjoy the ease of writing Go code for even a complex project :).
+4. Run the tests and make sure everything still works as expected using `go test ./...`.
+5. [Open a PR](https://github.com/fyne-io/fyne/compare) and work through the review checklist.
+
+
+# Contributing Code
+
+We aim to maintain a very high standard of code, through design, test and implementation.
+To manage this we have various checks and processes in place that everyone should follow, including:
+
+* We use the Go standard format (with tabs not spaces) - you can run `gofmt` before committing
+* Imports should be ordered according to the GoImports spec - you can use the `goimports` tool instead of `gofmt`.
+* Everything should have a unit test attached (as much as possible, to keep our coverage up)
+
+For detailed Code style, check [Contributing](https://github.com/fyne-io/fyne/wiki/Contributing#code-style) in our wiki please.
+
+# Decision Process
+
+The following points apply to our decision making process:
+
+* Any decisions or votes will be opened on the #fyne-votes Slack channel and follows lazy consensus.
+* Any contributors not responding in 4 days will be deemed in agreement.
+* Any PR that has not been responded to within 7 days can be automatically approved.
+* No functionality will be added unless at least 2 developers agree it belongs.
+
+Bear in mind that this is a cross platform project so any new features would normally
+be required to work on multiple desktop and mobile platforms.

+
+# About
+
+[Fyne](https://fyne.io) is an easy-to-use UI toolkit and app API written in Go.
+It is designed to build applications that run on desktop and mobile devices with a
+single codebase.
+
+# Prerequisites
+
+To develop apps using Fyne you will need Go version 1.17 or later, a C compiler and your system's development tools.
+If you're not sure if that's all installed or you don't know how then check out our
+[Getting Started](https://fyne.io/develop/) document.
+
+Using the standard go tools you can install Fyne's core library using:
+
+    go get fyne.io/fyne/v2@latest
+
+After importing a new module, run the following command before compiling the code for the first time. Avoid running it before writing code that uses the module to prevent accidental removal of dependencies:
+
+    go mod tidy
+
+# Widget demo
+
+To run a showcase of the features of Fyne execute the following:
+
+    go install fyne.io/fyne/v2/cmd/fyne_demo@latest
+    fyne_demo
+
+And you should see something like this (after you click a few buttons):
+
+<p align="center" markdown="1" style="max-width: 100%">
+  <img src="img/widgets-dark.png" width="752" alt="Fyne Demo Dark Theme" style="max-width: 100%" />
+</p>
+
+Or if you are using the light theme:
+
+<p align="center" markdown="1" style="max-width: 100%">
+  <img src="img/widgets-light.png" width="752" alt="Fyne Demo Light Theme" style="max-width: 100%" />
+</p>
+
+And even running on a mobile device:
+
+<p align="center" markdown="1" style="max-width: 100%">
+  <img src="img/widgets-mobile-light.png" width="348" alt="Fyne Demo Mobile Light Theme" style="max-width: 100%" />
+</p>
+
+# Getting Started
+
+Fyne is designed to be really easy to code with.
+If you have followed the prerequisite steps above then all you need is a
+Go IDE (or a text editor).
+
+Open a new file and you're ready to write your first app!
+
+```go
+package main
+
+import (
+	"fyne.io/fyne/v2/app"
+	"fyne.io/fyne/v2/container"
+	"fyne.io/fyne/v2/widget"
+)
+
+func main() {
+	a := app.New()
+	w := a.NewWindow("Hello")
+
+	hello := widget.NewLabel("Hello Fyne!")
+	w.SetContent(container.NewVBox(
+		hello,
+		widget.NewButton("Hi!", func() {
+			hello.SetText("Welcome :)")
+		}),
+	))
+
+	w.ShowAndRun()
+}
+```
+
+And you can run that simply as:
+
+    go run main.go
+
+> [!NOTE]  
+> The first compilation of Fyne on Windows _can_ take up to 10 minutes, depending on your hardware. Subsequent builds will be fast.
+
+It should look like this:
+
+<div align="center">
+  <table cellpadding="0" cellspacing="0" style="margin: auto; border-collapse: collapse;">
+    <tr style="border: none;"><td style="border: none;">
+      <img src="img/hello-light.png" width="207" alt="Fyne Hello Dark Theme" />
+    </td><td style="border: none;">
+      <img src="img/hello-dark.png" width="207" alt="Fyne Hello Dark Theme" />
+    </td></tr>
+  </table>
+</div>
+
+## Run in mobile simulation
+
+There is a helpful mobile simulation mode that gives a hint of how your app would work on a mobile device:
+
+    go run -tags mobile main.go
+
+Another option is to use `fyne` command, see [Packaging for mobile](#packaging-for-mobile).
+
+# Installing
+
+Using `go install` will copy the executable into your go `bin` dir.
+To install the application with icons etc into your operating system's standard
+application location you can use the fyne utility and the "install" subcommand.
+
+    go install fyne.io/tools/cmd/fyne@latest
+    fyne install
+
+# Packaging for mobile
+
+To run on a mobile device it is necessary to package up the application.
+To do this we can use the fyne utility "package" subcommand.
+You will need to add appropriate parameters as prompted, but the basic command is shown below.
+Once packaged you can install using the platform development tools or the fyne "install" subcommand.
+
+    fyne package -os android -appID my.domain.appname
+    fyne install -os android
+
+The built Android application can run either in a real device or an Android emulator.
+However, building for iOS is slightly different.
+If the "-os" argument is "ios", it is build only for a real iOS device.
+Specify "-os" to "iossimulator" allows the application be able to run in an iOS simulator:
+
+    fyne package -os ios -appID my.domain.appname
+    fyne package -os iossimulator -appID my.domain.appname
+
+# Preparing a release
+
+Using the fyne utility "release" subcommand you can package up your app for release
+to app stores and market places. Make sure you have the standard build tools installed
+and have followed the platform documentation for setting up accounts and signing.
+Then you can execute something like the following, notice the `-os ios` parameter allows
+building an iOS app from macOS computer. Other combinations work as well :)
+
+    $ fyne release -os ios -certificate "Apple Distribution" -profile "My App Distribution" -appID "com.example.myapp"
+
+The above command will create a '.ipa' file that can then be uploaded to the iOS App Store.
+
+# Documentation
+
+More documentation is available at the [Fyne developer website](https://developer.fyne.io/) or on [pkg.go.dev](https://pkg.go.dev/fyne.io/fyne/v2?tab=doc).
+
+# Examples
+
+You can find many example applications in the [examples repository](https://github.com/fyne-io/examples/).
+Alternatively a list of applications using fyne can be found at [our website](https://apps.fyne.io/).
+
+# Shipping the Fyne Toolkit
+
+All Fyne apps will work without pre-installed libraries, this is one reason the apps are so portable.
+However, if looking to support Fyne in a bigger way on your operating system then you can install some utilities that help to make a more complete experience.
+
+## Additional apps
+
+It is recommended that you install the following additional apps:
+
+| app           | go install                          | description                                                            |
+| ------------- | ----------------------------------- | ---------------------------------------------------------------------- |
+| fyne_settings | `fyne.io/fyne/v2/cmd/fyne_settings` | A GUI for managing your global Fyne settings like theme and scaling    |
+| apps          | `github.com/fyne-io/apps`           | A graphical installer for the Fyne apps listed at https://apps.fyne.io |
+
+These are optional applications but can help to create a more complete desktop experience.
+
+## FyneDesk (Linux / BSD)
+
+To go all the way with Fyne on your desktop / laptop computer you could install [FyneDesk](https://github.com/fyshos/fynedesk) as well :)
