S100P烧录4.5.0版本后使用Gstreamer视频解码只有软解码，4.5.0-beta有有GStreamer 硬件解码插件包吗
你好现在这个查看不了，可以给新的链接么
平台判断
def is_RDK():
try:
tree = open('/sys/firmware/devicetree/base/model', 'r', encoding='utf-8').read()
if "X5" in tree:

ubuntu安装gstreamer
前提条件
vim /usr/bin/hobot-loadko.sh
注释掉下述三句
# modprobe hobot_videosys &
# modprobe hobot_vpu &
# modprobe hobot_jpu &
重启系统
modprobe wave5
安装
# 基础组件与插件
sudo apt install -y \
gstreamer1.0-tools \
gstreamer1.0-plugins-base \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav
# v4l2硬编码组件
sudo apt install -y gstreamer1.0-plugins-bad
检查v4l2硬编码组件是否安装成功
gst-inspect-1.0 | grep v4l2
检查到包含以下属性说明硬编码组件安装成功。注意：要在对应的 vpu 驱动加载后再查看该信息
video4linux2: v4l2h264dec: V4L2 H264 Decoder
video4linux2: v4l2h264enc: V4L2 H.264 Encoder
video4linux2: v4l2h265dec: V4L2 H265 Decoder
video4linux2: v4l2h265enc: V4L2 H.265 Encoder
测试命令
输入png编码

配置码率需要打开开关
gst-launch-1.0 -e \
multifilesrc location="/userdata/v4l2/episode_000000/frame_%06d.png" caps="image/png,framerate=30/1" ! \
pngdec ! queue max-size-buffers=20 ! \

h264parse ! mp4mux streamable=true ! filesink location=out_v4l2.mp4
码率配置不生效的问题，用这里的命令。
码率控制功能默认未使能，编码器工作在固定QP模式，所以编码器不会根据配置的码率动态调整。增加的参数目的是使能码率控制。

这是png文件 ，自己找一些就好了
