Swap flush and memory barrier

5.5.6
Disable cap_sys_nice which causes amd gpu crash for some people. Do glFlush instead of swapBuffers, which allows it to run at high fps anyways. Downside is that some games on kde plasma can start to stutter. Kde plasma issue?

+GPU Screen Recorder uses Ffmpeg so GPU Screen Recorder supports all protocols that Ffmpeg supports.\
+If you want to reduce latency one thing you can do is to use the `-keyint` option, for example `-keyint 0.5`. Lower value means lower latency at the cost of increased bitrate/decreased quality.
 ## Replay mode
 Run `gpu-screen-recorder` with the `-c mp4` and `-r` option, for example: `gpu-screen-recorder -w screen -f 60 -r 30 -c mp4 -o ~/Videos`. Note that in this case, `-o` should point to a directory.\
 If `-df yes` is set, replays are save in folders based on the date.

 ## GPU Screen Recorder records night light when recording in HDR mode
 You can record with desktop portal option (`-w portal`) instead which ignores night light, if you are ok with recording without HDR.
 ## Kdenlive says that the video is not usable for editing because it has variable frame rate
-To fix this you can either record the video in .mkv format or constant frame rate (-fm cfr).
+To fix this you can either just press cancel, which will allow you to continue or record the video in .mkv format or constant frame rate (-fm cfr). I recommend recording the video in .mkv format and variable frame rate (-fm vfr).
 ## Colors look incorrect when recording HDR (with hevc_hdr/av1_hdr) or using an ICC profile
 KDE Plasma version 6.2 broke HDR and ICC profiles for screen recorders. This was changed in KDE plasma version 6.3 and recording HDR works now, as long as you set HDR brightness to 100% (which means setting "Maximum SDR Brightness" in KDE plasma display settings to 203) and set color accuracy to "Prefer color accuracy". If you want to convert HDR to SDR then record with desktop portal option (`-w portal`) instead.
 I don't know how well recording HDR works in wayland compositors other than KDE plasma.
 ## GPU Screen Recorder starts lagging after 30-40 minutes when launching GPU Screen Recorder from steam command launcher
 This is a [steam issue](https://github.com/ValveSoftware/steam-for-linux/issues/11446). Prepend the gpu-screen-recorder command with `LD_PREFIX=""`, for example `LD_PREFIX="" gpu-screen-recorder -w screen -o video.mp4`.
+## The video isn't smooth when gpu usage is 100%
+If you are using the flatpak version of GPU Screen Recorder then try installing GPU Screen Recorder from a non-flatpak source instead (such as from aur or from source). Flatpak has a limitation that prevents GPU Screen Recorder from running faster when playing very heavy games.
+## How do I apply audio effects, such as noise suppression?
+You have to use external software for that, such as Easy Effects or NoiseTorch.

 Maybe disable qp/vbr for replay. In that case we can preallocate all replay data (for both ram and disk) and write to that directly when receiving packet (dont do that when also recording at the same time).
    That could improve performance/disk write optimization and maybe even reduce ram usage because of less blocks/fragmentation.
+
+When rpc is added add the option to add/remove audio devices/app audio and also overlays (from new capture sources).
+
+Support hdr screenshot.
+
+Recreate opengl context on loss. This can happen if there is a gpu driver bug, causing context to need to be recreated. This is a nice improvement to not break recording even with buggy driver.
+
+Support saving video with surround sound. Surround sound audio capture does work, but it gets downmixed to stereo.
+
+Add (render) plugin support. To simplify it (and possibly best performance) create one rgba texture (with the size of the output video) that is used across all plugins.
+    Create a framebuffer and set this texture and the target and set the framebuffer as active before calling the plugins.
+    Then the plugins can render simply by doing simple opengl draw functions.
+    Maybe send some metadata to the plugin, such as video (and framebuffer) size. Although this data can be retrieved from the active framebuffer.
+
+Either support webcam support with raw yuyv, mapping the buffer directly to opengl. Or use mjpeg, mapping the buffer directly to vaapi jpeg decoder and then get then map the decoded buffer to opengl.
+    Some webcams dont support raw yuyv and many webcams support higher framerates for mjpeg.
+
+Allow medium, high, very_high and ultra quality for -bm cbr. If that is used then it will automatically estimate the best bitrate for that quality based on resolution and fps.
+    Maybe do this in the ui instead (or both?), to show estimated file size.
+
+Maybe remove shader compute code. It doesn't seem necessary anymore now that glSwapBuffer/glFinish isn't used. dbus server isn't needed anymore either, the code can be moved back to the gpu screen recorder process.
