And zero quality loss from the original RAW data that came out of the JVC.HWAccelIntro – FFmpeg /wiki/HWAccelIntroĪccelIntro FFmpeg Many platforms offer access to dedicated hardware I G E to perform a range of video-related tasks. A common feature of many hardware / - decoders to be able to generate output in hardware surfaces suitable for use by other components with discrete graphics cards, this means surfaces in the memory on the card rather than in system memory this is often useful for playback, as no further copying is required before rendering the output, and in some cases it can also be used with encoders supporting hardware C A ? surface input to avoid any copying at all in transcode cases.

How to use hardware acceleration with ffmpeg /questions/23289157/how-to-use-hardware-acceleration-with-ffmpeg FFmpeg 12.5 Computer hardware 12.3 Codec 11.4 Input/output 7 Encoder 6.6 Nvidia NVENC 4.3 Computing platform 4.2 Nvidia NVDEC 4 CUDA 3.9 Software 3.8 Video card 3.7 Advanced Video Coding 3.6 Hardware acceleration 3.4 Random-access memory 3.1 Transcoding 3.1 Application programming interface 2.9 Central processing unit 2.5 Rendering (computer graphics) 2.5 Data compression 2.3 Graphics processing unit 2.3 FFmpeg M K I offers access to many of these, with varying support. How to use hardware acceleration with ffmpeg After some investigation I was able to implement the necessary HW accelerated decoding on OS X VDA and Linux VDPAU. I will update the answer when I get my hands on Windows implementation as well. So let's start with the easiest: Mac OS X To get HW acceleration working on OS you should just use the following: avcodec find decoder by name "h264 vda" Note, however that you can accelerate h264 videos only on Mac OS with FFmpeg P N L.
