Release Notes

Version 2.3.0 [2025]

 * Support dual 4K.

 * Transpose fallback using NEON.

 * JPEG turbo can't decode CMYK. Use Wuffs as fallback.

 * Support Mesa 25: It reuses texture ids ("GL name reuse") which wasn't expected.

 * util.config_watch no longer ignores config changes
   if only device data updates.

 * Release video resource outside of main thread.

 * Optimize HDMI rendering of partially unused GL surface.

Version 2.2.0 [2025]

 * Various internal optimizations.

 * Uses custom VPU assembler code for faster 90/270
   rotations on KMS/DRM based playback on Pi3/Pi4.

 * Fixed RTSP stream playback potentially getting stuck.

 * Optional dithering using shaders to maybe avoid color
   banding.

Version 2.0.0 [2024] https://info-beamer.com/lnk/2.0.0

 * Completely recreated the video playback and surface
   management mechanism. info-beamer now uses KMS/DRM
   for setting video modes and controlling video output
   composition. OpenGL is now provided by Mesa.

   It now uses FFmpeg together with V4L2 for full
   hardware decoded video playback.

   As a result info-beamer is no longer reliant on
   any of the proprietary broadcom libraries.

 * HEVC playback on the Pi4 and Pi5 and now render videos
   into GL textures (non-raw videos).

 * H264 playback on the Pi5 is implemented in software
   as hardware support is no longer available.

 * Rotating raw videos by 90 or 270 degree now mostly
   transparently falls back to rendering into a texture
   and rotating that. This is necessary as rotating
   video output planes by 90 degrees is not supported
   by the hardware.

 * Screenshotting is now embedded into info-beamer
   itself. This is necessary for the new Pi4/5 versions
   as it's no longer possible to acces the video subsystem
   while info-beamer is in control. Snapshotting works
   using a new *screenshot/<dpy> command via the TCP
   interface. The screenshot is returned as JPEG data.
