我在linux 系统下看到了 /dev/vpu-server 还有 /dev/h265e这样的设备。
请问大家怎么使用,有没有对应的API接口?
顶一下
你可以看一下rockchip_mpp代码，它里面有用到。
另：印象中/dev/vpu-server 应该是3288板才有的，3399并没有这东西

请问 rockchip_mpp 的代码在哪里？ 我购买的是rk3328
还有我用到的解码是硬件解码还是软件解码怎么区分

我这个是从 firefly的内核中找到的。这是他们的H265E的编码的积存器的地址。
就是没有找打vpu_server的 接口文档

MPP (Media Process Platform) design (2016.10.12)
The mpp is a middleware library for Rockchip SoC’s cross platform media process.
The main purpose of mpp is to provide very high performance, high flexibility
and expansibility on multimedia (mainly video and image) process.
The design target of mpp is to connect different Rockchip hardware kernel driver
and different userspace application.
Rockchip has two sets of hardware kernel driver.
The first one is vcodec_service/vpu_service/mpp_service which is a high
performance stateless frame base hardware kernel driver. This driver supports
all available codecs that hardware can provide. This driver is used on Android/
Linux.
The second one is v4l2 driver which is developed for ChromeOS. It currently
supports H.264/H.265/vp8/vp9. This driver is used on ChomeOS/Linux.
Mpp plans to support serval userspace applications including OpenMax, FFmpeg,
gstreamer, libva.

请问大家有用到过ffmpeg的吗？ gstreamer 的实现我已经看到了

您好，请问您实现了gstreamer解码视频的方法了吗？可以给一个Demo吗？
