Video Component uses OMXPlayer on RPI

Test build that should have fixed all issues when using OMXPlayer as the video preview player on raspberry pi. It is compiled-out on other platforms and not available.

On Raspberry PI the player can be switched between VLC and OMX using this option in es_settings.cfg:

<bool name="VideoOmxPlayer" value="true" />

Setting the above to false makes ES use VLC as it does in the current version of ES. The default is 'true'.

When using OMXPlayer as the video player it is not possible to render anything on top of the video (like the raster lines in the oldroom theme). This is a limitation currently of this rendering method and unlikely to be fixed. Switching to VLC re-enables overlay on top of video.

The binary is RPi 2/3 only at the moment. The binary will not work on RPi1 but building from source might just work.

Test of omxplayer as video renderer

This is just a test build to evaluate the performance and temperature profile when using omxplayer as a video source (accelerated) as opposed to rendering with libvlc.

There are some issues, including:

1. The video is always on top. Nothing at present can be rendered over the video. This includes marquees in pixel video theme and the scanlines in oldroom
2. The video is rendered on top of GUI menus

I also haven't yet tested sound but I assume it is working.

WSOD fix - multi threaded texture loader

Latest build of multi-threaded texture loader with all known bugs addressed.

WSOD fix with multithreading and fixed bugs

The texture loading work is now complete pending testing. It should now run smoothly on raspberry pi and textures are loaded on demand if resources are low.

There is only one known outstanding issue:

1. Maximum possible texture memory is sometimes reported incorrectly

WSOD fix with threading - Tracking RetroPie/master

Reworking of TextureResource to allow dynamic unloading and loading of textures in a separate thread to allow large themes to be supported on a small amount of VRAM.

This release is for testing only and has some known issues:

1. Textures are not always rendered after changing themes
2. Sometimes carousel images are rendered the wrong size (observed only once)
3. Opacity of loading image is sometimes incorrect

In addition, more testing needs to be applied to the following areas:

1. Launching and resuming from a game
2. Video preview - as yet completely untested but has been reworked

WSOD fix - Tracking RetroPie/master

Current RetroPie master with inclusion of experimental fix for WSOD.

Texture memory is now purged based on a cache that maintains a fixed maximum texture footprint which is configurable in es_settings.cfg and via the UI in ES.

v0.2-beta.2 for Video Screensaver

Raspberry Pi 2/3 beta version that allows for testing of the video screensaver functionality.

v0.2-RPi-beta.1 Video View for Raspberry Pi 2/3

Based on RetroPie ES baseline but with the inclusion of a Video view which allows a video preview of each game to be displayed.

This binary distribution contains just the emulationstation executable that can be run on RetroPie v4.1 for Raspberry Pi 2/3 (https://github.com/RetroPie/RetroPie-Setup/releases/download/4.1/retropie-4.1-rpi2_rpi3.img.gz)

The binary may need executable permission set with chmod +x emulationstation and can either be run from any directory or can be copied over /opt/retropie/supplementary/EmulationStation/emulationstation, backing up the original file first.

v0.1-beta.7 for Video Preview

Add themeable sound that is played when system list is scrolled

v0.1-beta.6 for Video Preview

• Rework logic behind starting and stopping videos to address strange behaviour with multiple videos playing, videos starting at the wrong time, etc.
• Issue #5: Add option to select random game videos as screensaver
• Fix relative paths in video and marquee metadata (yay!)
