The image quality and file size reduction that can be achieved with just a basic application of NLMeans are often quite dramatic. That said, the software implementation is incredibly slow. OpenCL-capable GPUs are now ubiquitous in the market, and it is time to bring an OpenCL implementation of the NLMeans algorithm to HandBrake.-opencl_options. See the "OpenCL Options" section in the ffmpeg-utils manual for the complete list of supported options. Amongst others, these options include the ability to select a specific platform and device to run the OpenCL code on. By default, FFmpeg will run on the first device of the first platform. See ffmpeg -filters to view which filters have timeline support. 6 Changing options at runtime with a command. Some options can be changed during the operation of the filter using a command.

OpenCL filters and bus speed I recently started using the hardware openCL nlmeans filter and noticed a nice improvement. I noticed that my FPS seem to be set at 6 for one encode, 3 for 2, 2 for 3 etc which means there is a bottleneck when the cpu offloads the frame to the GPU and regardless of the number of encodes I'll be getting the same FPS.OpenCL filters and bus speed I recently started using the hardware openCL nlmeans filter and noticed a nice improvement.

I now want to use ffmpeg also for these steps, but need help on the cmd for the filters. I use ffmpeg on windows 7 64 Bit, so syntax for windows, please. Might turn to linux as a next step, but I am not convinced that a raspberry pi is a good choice to save power.Use ffmpeg to pad the audio input with silence, so that the video stream will always result the shortest and will be converted until the end in the output file when using the shortest option: ffmpeg -i VIDEO -i AUDIO -filter_complex "[1:0]apad" -shortest OUTPUT aphaser Add a phasing effect to the input audio.

You can pass unaligned data only to FFmpeg APIs that are explicitly documented to accept it. There are three output files specified, and for the first two, no -map options are set, so ffmpeg will select streams for these two files automatically.. out1.mkv is a Matroska container file and accepts video, audio and subtitle streams, so ffmpeg will try to select one of each type. For video, it will select stream 0 from B.mp4, which has the highest resolution among all the input video streams.Sep 01, 2020 · The accessible parameters in the current FFmpeg version of nlmeans are as follows... s - Set denoising strength. Default is 1.0. Must be in range [1.0, 30.0]. p - Set patch size. Default is 7. Must be odd number in range [0, 99]. pc - Same as p but for chroma planes.
