Expected Behavior

Recognize that the OpenH264 is installed.

Current Behavior

OBS-Studio doesn't start recording. Instead, it returns "Failed to open OpenH264: Encoder not found"

Steps to Reproduce

  1. Set the Settings > Output > Recording > Video Encoder to "Software (OpenH264)"
  2. Save the new settings
  3. Click on "Start Recording"

Anything else we should know?

The OBS Studio log URL seems to contain no data (since I couldn't start recording), so I'm including it manually here: ``` 09:09:14.005: Platform: Wayland 09:09:14.005: CPU Name: AMD Ryzen 7 5700U with Radeon Graphics 09:09:14.005: CPU Speed: 1929.475MHz 09:09:14.006: Physical Cores: 8, Logical Cores: 16 09:09:14.006: Physical Memory: 5775MB Total, 948MB Free 09:09:14.006: Kernel Version: Linux 6.10.4-200.fc40.x86_64 09:09:14.006: Distribution: "Fedora Linux" 40 09:09:14.006: Desktop Environment: GNOME (gnome) 09:09:14.006: Session Type: wayland 09:09:14.009: Qt Version: 6.7.2 (runtime), 6.7.2 (compiled) 09:09:14.009: Portable mode: false 09:09:14.044: OBS 30.2.2 (linux) 09:09:14.044: --------------------------------- 09:09:14.044: --------------------------------- 09:09:14.044: audio settings reset: 09:09:14.044: samples per sec: 48000 09:09:14.044: speakers: 2 09:09:14.044: max buffering: 960 milliseconds 09:09:14.044: buffering type: dynamically increasing 09:09:14.054: --------------------------------- 09:09:14.054: Initializing OpenGL... 09:09:14.054: Using EGL/Wayland 09:09:14.093: Initialized EGL 1.5 09:09:14.108: Loading up OpenGL on adapter AMD AMD Radeon Graphics (radeonsi, renoir, LLVM 18.1.6, DRM 3.57, 6.10.4-200.fc40.x86_64) 09:09:14.109: OpenGL loaded successfully, version 4.6 (Core Profile) Mesa 24.1.5, shading language 4.60 09:09:14.139: --------------------------------- 09:09:14.139: video settings reset: 09:09:14.139: base resolution: 1920x1080 09:09:14.139: output resolution: 1280x720 09:09:14.139: downscale filter: Bicubic 09:09:14.139: fps: 60/1 09:09:14.139: format: NV12 09:09:14.139: YUV mode: Rec. 709/Partial 09:09:14.139: NV12 texture support enabled 09:09:14.139: P010 texture support not available 09:09:14.144: Audio monitoring device: 09:09:14.144: name: Default 09:09:14.144: id: default 09:09:14.144: --------------------------------- 09:09:14.162: Failed to load 'en-US' text for module: 'decklink-captions.so' 09:09:14.181: Failed to load 'en-US' text for module: 'decklink-output-ui.so' 09:09:14.198: A DeckLink iterator could not be created.

OpenH264 is not currently supported by OBS. Fedora provides custom patches, please report this to them.
