![]() ![]() I wonder if there’s a way to use the on-chip Intel GPU more? Probably not worth the hassle. Ubuntu 17.10 while I’m at it these LTS releases are reliable but limiting. The old server is 6 years old, maybe it’s time for a full hardware upgrade. Previously the options were global - youd set them once on /dev/video0 or whatever, and they would take effect when the device was later opened for capture. I could add a GPU to the existing server but it seems to be $200 minimum. 1 Answer Sorted by: 3 So when the V4L2 interface started providing hardware encoding/decoding, the method for setting these options changed. Encode AVI to h. ![]() 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. This article documents some of the ffmpeg command line switches require to perform hardware video encoding on both NVIDIA and AMD GPUs. ![]() I really wanted to test this with H265 encoding, but the hevc_nvenc encoder does not work with the Kepler-class K80 hardware. c:v libx264 selects the video encoder libx264, TranscodingJobType. Normal desktop machines probably have less of a spread in results. Videos: Improve FFmpeg parameters for Intel QSV hardware transcoding Issue 2222. This is all on a 1 vCPU, K80 Google Compute server. Hardware decoding is nice but not a huge improvement. So the hardware h264 encoder is about 7x faster than software. cuvid hardware decode, h264_nvenc hardware encode: 2.8x real time.Thanks to the C++ code underneath the Python bindings, it allows you to achieve high GPU utilization within tens of code lines. software decode, h264_nvenc hardware encode: 2.7x real time VPF provides developers with a simple, yet powerful Python tool for fully hardware -accelerated video encoding, decoding and processing classes.software decode, h264 software encode: 0.355x real time.x264 is a free library for encoding H264/. This is a shell script to build x264 for iOS apps. but before Android 4.1, the only choice was a software encoder (FFmpeg or x264). This guide is focused entirely on streaming with the x264 encoder. 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. In this section, you use a hardware video encoder to implement a special. ![]()
