注意其中這一段, hevc_前綴代表適用於H.265編碼

 V....D libx265              libx265 H.265 / HEVC (codec hevc)
 V....D hevc_amf             AMD AMF HEVC encoder (codec hevc)
 V....D hevc_mf              HEVC via MediaFoundation (codec hevc)
 V....D hevc_nvenc           NVIDIA NVENC hevc encoder (codec hevc)
 V..... hevc_qsv             HEVC (Intel Quick Sync Video acceleration) (codec hevc)
 V....D hevc_vaapi           H.265/HEVC (VAAPI) (codec hevc)

Windows系統下可用的硬件編碼:

libx265 : 默認hevc編碼器, 使用CPU編碼
hevc_nvenc : Nvidia 硬件編碼器
hevc_amf : AMD顯卡硬件編碼器
hevc_qsv : Intel 硬件編碼器

Linux系統下可用的硬件編碼:

1
2
3

libx265 : 默認hevc編碼器, 使用CPU編碼
hevc_vaapi : Intel 硬件編碼器
hevc_nvenc nvenc_hevc : Nvidia 硬件編碼器

MacOS系統可用的硬件編碼:

1
2
3

libx265 : 默認hevc編碼器, 使用CPU編碼
hevc_videotoolbox : Intel 硬件編碼器
hevc_videotoolbox : Apple Silicon硬件加速

通過使用不同的視頻編碼器,使用不用的硬件進行編碼, 通過 -c:v 指定, 比如下面的命令指定Nvidia 硬件編碼器

`1`	`ffmpeg -i 1.mp4 -c:v hevc_nvenc out.mp4`

簡單對比測試同一段視頻
