Title: AMD AMF Encoders Detected by FFmpeg but Not Available in Kdenlive 25.12
Windows
System:
* Windows 11 25H2
* AMD Ryzen 5000 Series with Radeon Graphics
* Kdenlive 25.12.0
Observations:
* Kdenlive uses:
C:\Program Files\kdenlive\bin\ffmpeg.exe
* FFmpeg reports:
h264_amf
hevc_amf
av1_amf
* FFmpeg build contains:
--enable-amf
* Kdenlive render profile MP4-H264/AAC uses:
vcodec=libx264
* No AMD AMF render presets are visible in the Render dialog.
* During rendering, Windows Task Manager shows Video Codec 0 at 0%.
Expected:
Kdenlive should expose AMD hardware encoding presets or allow selection of
h264_amf/hevc_amf when FFmpeg detects AMF encoders.
Actual:
Rendering falls back to libx264 CPU encoding even though FFmpeg supports AMD
AMF.
