--- Comment #1 from NVDA-Dev <louise9...@gmail.com> --- STEPS TO REPRODUCE 1. Open a video in kdenlive, place it in timeline, go to render video, add a profile based on mp4, change libx264 to h264_nvenc. name it nvenc, click ok to add a new profile, then select it as render profile for video, click render, after render play video youll get no sound. Restart kdenlive go to render and skip adding a profile, click on nvenc profile again, you will get unsupported codec: h264_nvenc, delete old profile do same steps above click render and will still get black video with sound. And video engine utilization 0 percent. 2. For proxies go into project settings select x264_nvenc(in my install at least you will see and error sign next to it) select it for timeline preview then go to proxies enable them and images as well, select x264_nvenc as proxies encoder. Drag video into timeline. Right click video in source window select proxy clip and you will see "Unknown decoder 'h264_cuvid'" in the problem log. OBSERVED RESULT EXPECTED RESULT 1. Black screen when playing rendered video with no video and no thumbnail(black thumbnail) when using nvenc encoder but audio is clearly working. Video engine utilization 0 percent while rendering. gpu utilzation 20+ percent while rendering. 2. Proxies failure when using cuda/cuvid/nvenc as decoder. You will get "Unknown decoder 'h264_cuvid'" in problem log. 3. Install version 17.xxx.xxx from ubuntu/mint repos and with properly configured ffmpeg you wil get no problems with gpu acceleration. -- You are receiving this mail because: You are watching all bug changes.
