M_7 = dbg_pcm10_video_downscale_time_cpu Deshaking CPU = M_8 / M_9 M_4 = dbg_pcm10_video_downscale_time_cpu Sharpening OCL = M_5 / Min(M_6,M_7) M_2 = dbg_pcm10_video_go_time Sharpening CPU = M_3 / M_4 The workloads measure the frames produced per second in the video editing program. Fast downscaling, common for example in use with mobile devices.The workloads perform the following tasks: The Video Editing test simulates editing videos in a video editing program. If the OpenCL test takes longer than the CPU test, the CPU run time is used instead.If the OpenCL of the Stage 2 test takes longer than the CPU version, the CPU result is used instead.Uses publicly available executable FFmpeg.exe.Similar to Video to go test in PCMark 8.Code path: x86/圆4 and whatever is the implementation with Media Foundation H.264 codecs installed on the system.Uses Media Foundation Fast transcode feature to transcode video files to a format suitable for mobile use.The benchmark application selects a preferred OpenCL device to use.
The Video Editing test uses FFmpeg on the sharpening and deshaking parts. Hardware acceleration is allowed to be used if the system supports it and has the necessary Media Foundation setup done. Windows Media Foundation is used with its built-in codecs to transcode video. The Video Editing test uses parts from PCMark 8 Video Editing and Media To Go tests. The Video Editing test use cases capture some common uses of video editing applications. It has some learning curve for things beyond just converting a file 1:1, but as a library, many programs such as OBS, Blender, Shotcut, Drawpile and KDEnLive implements it for tasks such as rendering and recording videos out of them.Solution home PCMark 10 Digital Content Creation test group Video Editing
FFmpeg is a cross-platform framework to record, convert, and stream video and audio, it provides an easy way to convert video and audio to other formats. This blog we are going to pick an open source software and locate the SIMD code from the source code of the software and then determine the SIMD code usage in a certain program. Ask HN: Is there other software similar to Vim and Emacs?.
