when vlv hardware decoding is set to auto or vadpu, there is no video for AV1 codec, but hevc seems unaffected. forcing vaapi displays video for all video types system info: Operating System: Fedora Linux 41 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 Kernel Version: 6.12.9-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 8845HS w/ Radeon 780M Graphics Memory: 30.6 GiB of RAM Graphics Processor: AMD Radeon Graphics & RTX 4060 Laptop Manufacturer: LENOVO Product Name: 83DH System Version: Legion Slim 5 16AHP9 Reproducible: Always

Apparently, this is a known issue with libvdpau. libvdpau is not Wayland-aware, and tries to use the X11 DRI2 extension to detect the graphics driver in use; if it can't autodetect, then it assumes "nvidia" because they're the major promoters of that API. This works fine on Xorg but does not on Xwayland because only the DRI3 extension is supported, hence it fails (unless you happen to have nvidia graphics). This isn't specific to vlc; vdpauinfo demonstrates the same issue. (While one would think this would be as simple as making libvdpau use the DRI3 extension, given how long this has been an issue, I wouldn't hold by breath.) Recommendations: 0) read bug 1305699 and the links therein for more details; then 1) export VDPAU_DRIVER=radeonsi (based on your hardware reported above) 2) AND/OR use VA-API instead. Hope this helps. *** This bug has been marked as a duplicate of bug 1305699 ***
SO i tried to use X org, but it seems that the problem persisted. for the record this is what vdpauinfo says in Plasma(X11) ``` display: :0 screen: 0 API version: 1 Information string: G3DVL VDPAU Driver Shared Library version 1.0 Video surface: name width height types ------------------------------------------- 420 16384 16384 NV12 YV12 422 16384 16384 UYVY YUYV 444 16384 16384 Y8U8V8A8 V8U8Y8A8 420_16 16384 16384 P010 P016 422_16 16384 16384 444_16 16384 16384 Decoder capabilities: name level macbs width height ---------------------------------------------------- MPEG1 --- not supported --- MPEG2_SIMPLE --- not supported --- MPEG2_MAIN --- not supported --- H264_BASELINE 52 65536 4096 4096 H264_MAIN 52 65536 4096 4096 H264_HIGH 52 65536 4096 4096 VC1_SIMPLE --- not supported --- VC1_MAIN --- not supported --- VC1_ADVANCED --- not supported --- MPEG4_PART2_SP --- not supported --- MPEG4_PART2_ASP --- not supported --- DIVX4_QMOBILE --- not supported --- DIVX4_MOBILE --- not supported --- DIVX4_HOME_THEATER --- not supported --- DIVX4_HD_1080P --- not supported --- DIVX5_QMOBILE --- not supported --- DIVX5_MOBILE --- not supported --- DIVX5_HOME_THEATER --- not supported --- DIVX5_HD_1080P --- not supported --- H264_CONSTRAINED_BASELINE 0 65536 4096 4096 H264_EXTENDED --- not supported --- H264_PROGRESSIVE_HIGH --- not supported --- H264_CONSTRAINED_HIGH --- not supported --- H264_HIGH_444_PREDICTIVE --- not supported --- VP9_PROFILE_0 --- not supported --- VP9_PROFILE_1 --- not supported --- VP9_PROFILE_2 --- not supported --- VP9_PROFILE_3 --- not supported --- HEVC_MAIN 186 139264 8192 4352 HEVC_MAIN_10 186 139264 8192 4352 HEVC_MAIN_STILL --- not supported --- HEVC_MAIN_12 --- not supported --- HEVC_MAIN_444 --- not supported --- HEVC_MAIN_444_10 --- not supported --- HEVC_MAIN_444_12 --- not supported --- AV1_MAIN 0 139264 8192 4352 AV1_HIGH --- not supported --- AV1_PROFESSIONAL --- not supported --- Output surface: name width height nat types ---------------------------------------------------- B8G8R8A8 16384 16384 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 P010 P016 A8I8 I8A8 R8G8B8A8 16384 16384 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 P010 P016 A8I8 I8A8 R10G10B10A2 16384 16384 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 P010 P016 A8I8 I8A8 B10G10R10A2 16384 16384 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 P010 P016 A8I8 I8A8 Bitmap surface: name width height ------------------------------ B8G8R8A8 16384 16384 R8G8B8A8 16384 16384 R10G10B10A2 16384 16384 B10G10R10A2 16384 16384 A8 16384 16384 Video mixer: feature name sup ------------------------------------ DEINTERLACE_TEMPORAL y DEINTERLACE_TEMPORAL_SPATIAL - INVERSE_TELECINE - NOISE_REDUCTION y SHARPNESS y LUMA_KEY y HIGH QUALITY SCALING - L1 y HIGH QUALITY SCALING - L2 - HIGH QUALITY SCALING - L3 - HIGH QUALITY SCALING - L4 - HIGH QUALITY SCALING - L5 - HIGH QUALITY SCALING - L6 - HIGH QUALITY SCALING - L7 - HIGH QUALITY SCALING - L8 - HIGH QUALITY SCALING - L9 - parameter name sup min max ----------------------------------------------------- VIDEO_SURFACE_WIDTH y 48 4096 VIDEO_SURFACE_HEIGHT y 48 4096 CHROMA_TYPE y LAYERS y 0 4 attribute name sup min max ----------------------------------------------------- BACKGROUND_COLOR y CSC_MATRIX y NOISE_REDUCTION_LEVEL y 0.00 1.00 SHARPNESS_LEVEL y -1.00 1.00 LUMA_KEY_MIN_LUMA y LUMA_KEY_MAX_LUMA y ```
