For instance, GoPro 4K HEVC videos are not friendly to many editor apps. Below are two disadvantages of H.265 compared with H.264:ġ. However, bear in mind that H.265 is still less common than its predecessor (H.264) in the industry.

This is quite helpful for your viewers in that their devices will require less bandwidth and processing power to decompress all information and watch a stream. This enables H.265 to compress information more efficiently.Īdditionally, H.265 also has an improved motion compensation and spatial prediction than H.264 does. Although macroblocks can go anywhere from 4×4 to 16×16 block sizes, CTUs are able to process up to 64×64 blocks. Then, another perk of H.265 is the fact that it processes data in coding tree units. This significantly lowers the required bandwidth. The biggest difference here is that H.265/HEVC allows for further reduced file size of your live video streams. H.265 is more advanced than H.264 because of various reasons.

Formats: Original: nv12 | HW: p010le | SW: p010le If I add “-pix_fmt yuv420p” it works, but my cpu utilization skyrockets (ffmpeg uses 100% out of 800%), leading me to believe the reformatting is in software:įfmpeg -y -v verbose -c:v hevc_cuvid -i ~/bbb_hevc_3840x1920.mp4 -c:v h264_nvenc output.mp4 How do I convert pix format in hardware, since apparently scale_cuda does NOT support pixel format changes even though it can take that as an argument. Using the latest ffmpeg(3.4.2) compiled with the latest CUDA (9.1) I am unable to encode 10 bit h264 (see below output).
