二.H264硬件编解码耗时

通过修改环境变量，可以查看硬件编解码的耗时，下面以1080p H264的编解码过程，来看下耗时情况（注意，如果没有接串口调试工具，而是通过ssh连接的设备，默认看不到系统信息，需要通过dmesg命令来看，dmesg -c可以查看信息并清除）：

编解码调试信息打开命令：

echo 0x0100 > /sys/module/rk_vcodec/parameters/mpp_dev_debug

1.编码H264耗时：

命令：

mpi_enc_test -w 1920 -h 1080 -t 7 -i test-420sp-nv12-40i.yuv -o ./test-420sp-nv12.h264 -n 40 -r 25

三.jpeg硬件编解码耗时

通过修改环境变量，可以查看硬件编解码的耗时，下面以1080p jpeg/mjpeg的编解码过程，来看下耗时情况（注意，如果没有接串口调试工具，而是通过ssh连接的设备，默认看不到系统信息，需要通过dmesg命令来看，dmesg -c可以查看信息并清除），另外注意，jpeg有图片质量之分，所以不同的图片，即使都是1080p的，编解码耗时也有可能不同。

编解码调试信息打开命令：

echo 0x0100 > /sys/module/rk_vcodec/parameters/mpp_dev_debug

1.编码jpeg

命令：

mpi_enc_test -w 1920 -h 1080 -t 8 -i test-rgba-rgb32-40i.yuv -o ./zl-rgba.jpg -n 1 -r 25 -f 65549

耗时：

[56764.844590] ffb90000.vepu: pid: 2942, session: 545d95af, time: 14713 us

2.解码jpeg

命令：

mpi_dec_test -i zl-rgba.jpg -t 8 -w 1920 -h 1080 -o zl-rgba.yuv

耗时：

[57461.346905] ffb90400.vdpu: pid: 1929, session: 9bf49e81, time: 14311 us
