I wonder if there’s a way to use the on-chip Intel GPU more? Probably not worth the hassle. The best would be the h264vaapi that is now in ffmpeg. Ubuntu 17.10 while I’m at it these LTS releases are reliable but limiting. Using them in TorchAduio requires FFmpeg built with NVENC/NVDEC. ![]() but before Android 4.1, the only choice was a software encoder (FFmpeg or x264). Using hardware encoder/decoder improves the speed of loading and saving certain types of videos. The old server is 6 years old, maybe it’s time for a full hardware upgrade. In this section, you use a hardware video encoder to implement a special. Tested with Medium, fast, and veryfast ffmpeg -y -re -i input.mp4 -c:v libx264 -preset medium -b:v 5M. I could add a GPU to the existing server but it seems to be $200 minimum. experimental FFMPEG hardware encoder for Android - GitHub - mikbry/ffmpeg-mediacodec-encoder: experimental FFMPEG hardware encoder for Android. I’m regularly doing H264 -> H265 transcoding at home now and on my i7-2600 it transcodes 720p video at just about real time.īetween the video transcoding and the machine learning I’m itching to own my own Linux box with a GPU in it. I really wanted to test this with H265 encoding, but the hevc_nvenc encoder does not work with the Kepler-class K80 hardware. These flags indicate that build FFmpeg with Raspberry Pi-specific OpenMAX encoder, which is silghtly different from the normal version of the OpenMAX encoder (e.g. Normal desktop machines probably have less of a spread in results. This is all on a 1 vCPU, K80 Google Compute server. Hardware decoding is nice but not a huge improvement. The High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H. ![]() ![]() So the hardware h264 encoder is about 7x faster than software. cuvid hardware decode, h264_nvenc hardware encode: 2.8x real time.software decode, h264_nvenc hardware encode: 2.7x real time.software decode, h264 software encode: 0.355x real time.Since I have a Linux VM with a big GPU lying around I thought I’d take a quick stab at hardware accelerated video transcoding using ffmpeg. ![]()
