GE-Proton10-33-rtsp24-1

This release is not recommended for distribution as it contains some gross hacks which should enable less audio dropout, better audio recovery, and hopefully videoplayer performance impact reductions.

If you do try it leave a comment in issues if anything is broken or if it works better for you specifically over 23!

GE-Proton10-33-rtsp23-4 Released

Fix MKV/Jellyfin playback and big-endian audio

• Ignore subtitle streams (ASS/SSA) that caused pipeline abort on web sources
• Accept H264 avc stream format for MKV container playback
• Don't fatal on missing plugins for HTTPS sources

GE-Proton10-33-rtsp23-3

Fixed an audio issue with mediamtx, thankyou to kazu0617

GE-Proton10-33-rtsp23-2

This release enables builds flags for video decode/ encode GPU acceleration override.

Currently borked but if you know how to enable you are free to experiment.

Do note all I was able to produce was video with artifacts, likely why it was disabled to begin with.

No support will be offered for those experimenting but patches are always welcome, hack it up 👍

GE-Proton10-33-rtsp23-1

We've never been more back!

Fix crash when resyncing/disconnecting RTSP streams (use-after-free in wg_parser disconnect)

• Fix hang and use-after-free when a wg_parser is disconnected while there's still an outstanding read
• Fix hang in IMFMediaSource::Shutdown

Fourth time's a charm.

Based on GE-Proton10-33

What's new

• Rebased RTSP patchset the previous rtsp21 series (including -1 and -2 hotfixes) had a crash-on-launch issue with VRChat caused by patches not applying cleanly to the GE-Proton10-33 wine base. This has been fully resolved with a refreshed patchset from upstream
• 60 media/gstreamer patches for RTSP livestream playback in VRChat video players
• Enabled RTSP transport stack in gstreamer build (rtp, rtsp, rtpmanager, udp)
• New winevulkan performance optimizations
• Media session private work queues for smoother playback
• Various ntdll and kernelbase performance improvements
• yt-dlp integration patches for video URL resolution
• Spout2 support, Thanks Lina!
• Wayland qt window decor
• OpenXR/ OpenVR runtime decouple, OpenXR games may now be run without an OpenVR runtime configured. (Huge thanks to GloriousEggroll here!)

Known issues

• The PROTON_GST_VIDEO_ORIENTATION environment variable is not available in this build (upstream patch conflict)
