It works very well and I even can build a 1080p mosaic using lossless preset and high444p profile. I've changed for a combination of hstack and vstack as you can see here : ffmpeg \ The problem was about the overlay filter which is too slow. Moreover, I'd like ffplay to use hardware acceleration but I didn't manage to force it to use h264_cuvid. Mosaic video flux is uploaded in the GPU.Īfter this I'm not sure if the encoded video is retrieved by the CPU and then piped to ffplay or if it's stays in the GPU and directly displayed on the monitor. Height: 1.00 to 8.00 feet Spread: 0.75 to 2.Mosaic is made by the CPU using overlay filter.The four flux are downloaded in the CPU and formated in NV12.Scaling to 720p is also performed by the GPU. ![]() The four videos are decoded by the GPU.If you like the Roboto font, download it here. backgrounds, no people, choice, pattern, tile, textured, black color, creativity, mosaic, mutli shape quilt, indoors, 2K, Texture, abstract, Shape.
