Implement Running Godot as Movie Writer * Allows running the game in "movie writer" mode. * It ensures entirely stable framerate, so your run can be saved stable and with proper sound (which is impossible if your CPU/GPU can't sustain doing this in real-time). * If disabling vsync, it can save movies faster than the game is run, but if you want to control the interaction it can get difficult. * Implements a simple, default MJPEG writer. This new features has two main use cases, which have high demand: * Saving game videos in high quality and ensuring the frame rate is *completely* stable, always. * Using Godot as a tool to make movies and animations (which is ideal if you want interaction, or creating them procedurally. No other software is as good for this). **Note**: This feature **IS NOT** for capturing real-time footage. Use something like OBS, SimpleScreenRecorder or FRAPS to achieve that, as they do a much better job at intercepting the compositor than Godot can probably do using Vulkan or OpenGL natively. If your game runs near real-time when capturing, you can still use this feature but it will play no sound (sound will be saved directly). Usage: $ godot --write-movie movie.avi [scene_file.tscn] Missing: * Options for configuring video writing via GLOBAL_DEF * UI Menu for launching with this mode from the editor. * Add to list of command line options. * Add a feature tag to override configurations when movie writing (fantastic for saving videos with highest quality settings).

Change window title in Movie Maker mode to display useful information The frame number and movie time is now displayed in the window title. This way, you can see how quickly the video recording is advancing in real-time (and perhaps tweak your settings if it's going too slow).

Add a Movie Quit On Finish property to AnimationPlayer This quits the project when an animation is done playing in the given AnimationPlayer, but only in Movie Maker mode. When this happens, a message is printed with the absolute path of the AnimationPlayer node that caused the engine to quit. This can be used to create videos that stop at a specified time without having to write any script. A report is now also printed to the console when the video is done recording (as long as the engine was exited properly). This report is unfortunately not always visible in the editor's Output panel, as it's printed too late. A method was also added to get the path to the output file from the scripting API.
