Hardware vs Software Frames

Quadra is built for hardware transcoding, and this substantially increases transcoding performance for most workloads.

note

Please refer to the application note APPS548-Codensity Quadra YUVbypass for more details.

To enable YUVbypass and use hardware transcoding use the following parameter

-xcoder-params "out=hw"

Examples

Hwframes On ( YUVbypass On ): If

Hwframes Off (Use the same approach as traditional transcoding ie FFmpeg):

ffmpeg -vsync 0 -c:v h265_ni_quadra_dec -dec 0 -xcoder-params "out=sw" \
-i input.h265 \
-c:v h264_ni_quadra_enc -enc 0 \
-xcoder-params "RcEnable=1:bitrate=7500000" output.h264
