SVT-HEVC is open-source hevc/h265 sw encoder (supported in linux and windows). For details how to compile and to run pls. go to the official site
Sources can be downloaded with ‘git clone’ from https://github.com/OpenVisualCloud/SVT-HEVC
If you are reluctant to compile the sources you can download binaries (SvtHevcEncApp.exe, SvtHevcEnc.lib) from
To compile SVT-HEVC in Windows (with Visual Studio compiler) open the command prompt and enter to ‘SVT-HEVC/Build/windows’, then run (provided that Visual Studio 2017 installed):
build.bat 2017 releaseNote: for Visual Studio 2019 release use:build.bat 2019 release
SVT-HEVC encoder exe-file SvtHevcEncApp.exe (as well as SvtHevcEnc.dll and SvtHevcEnc.lib) is created at SVT-HEVC\Bin\Release\ . To run SvtHevcEncApp.exe the file SvtHevcEnc.dll should be in the path folders.
Example:
Encoding 1920×1080 yuv420p source, 60 fps, VBR rate control with the target bitrate 10Mbps, tile grid 2×2, low latency, closed GOPs, etc.
SvtHevcEncApp.exe -i test1080p.yuv -w 1920 -h 1080 -n 100 -fps 60 -tbr 10000000 -sao 1 -umv 0 -lad 0 -rc 1 -pred-struct 0 -intra-period 29 -irefresh-type 1 -tile_row_cnt 2 -tile_col_cnt 2 -tile_slice_mode 1 -b test2.h265
'-rc 1' - setting VBR Rate Control'-lad 0' - no look ahead (due to low latency)'-pred-struct 0' - IPPP GOP structure (low latency, no B frames)'-intra-period 29 -irefresh-type 1' - closed GOP of 30 frames'-n 100' encode first 100 frames '-tile_row_cnt 2 -tile_col_cnt 2' - create 2x2 tile grid '-tile_slice_mode 1 ' - each tile is encapsulated into single sliceHVS-related parameters:
'-brr 1' means bitrate reduction by low-pass filtering of the transform coefficients
-sharp 1 improved background sharpness using adaptive quantization
SvtHevcEncApp.exe -i crowdrun1080p50fps.yuv -brr 1 -sharp 1 -w 1920 -h 1080 -n 100 -fps 60 -tbr 10000000 -sao 1 -umv 0 -lad 0 -rc 1 -pred-struct 0 -intra-period 29 -irefresh-type 1 -tile_row_cnt 2 -tile_col_cnt 2 -tile_slice_mode 1 -b test_crowd.h265
