8-bit Usage Reference

Taking YUV to MP4 conversion as an example, this section provides a command example for encoding 8-bit sequences using the HW265Enc encoder in FFmpeg.

When you enter command line parameters, the output file name must be written at the end, and other FFmpeg built-in parameters must be written after the ffmpeg command. The libhw265 encoder parameters are written after libhw265. Parameter types and descriptions are shown in Table 1.

Command example:

ffmpeg -s 1920x1080 -i input.yuv -bf 0 -c:v libhw265 -wpp_threads 4 output.mp4

Information similar to the following is displayed:
