您嘗試過哪種媒體播放器？我已經安裝了linux 5.4的驅動程序。我執行了自述文件中的說明。但是，如何將cedar引入ffmpeg或mplayer？我可以使用哪個命令行運行視頻？謝謝。

CedarX并不是一个通用型的媒体框架，它不像v4l2那样可以无缝集成到很多现有的媒体工具里。libcedar（libcdc）是该驱动的用户层动态连接库，它可能是全志专有的二进制代码，你可以从你的经销商处询问是否可以得到这个动态连接库的副本和开发手册。所有的编解码程序需要自己开发。

快速的测试方式是直接用gstreamer1.0版本。

你好！
根据github上的指导移植驱动，并且在/dev目录下找到cedar_dev和ion节点。

并且完成了下面的操作：

Allwinner CedarX userspace library
Based on lindenis-v536 SDK

Add package to buildroot system
Copy dir "buildroot-package/libcedarc" to "buildroot/package"

Modify "buildroot/package/Config.in", add package source to any menu you want

source "package/libcedarc/Config.in"
Demo

menu "Hardware handling"
source "package/libcedarc/Config.in" # <--Add
source "package/acsccid/Config.in"
source "package/bcm2835/Config.in"


Build
make menuconfig
Select "libcedarc" package
make
Work with ffmpeg (tested with buildroot 2020.02.1)
make menuconfig
goto "> Target packages > Audio and video applications > ffmpeg"
set "(--enable-omx) Additional parameters for ./configure"
recompile ffmpeg

以上操作完之后，要如何使用h264硬编码的功能呢？请大佬指点！

Hello, how many fps and maximum resolution do you get with cedarx from aodzip? I can encode 640x480 at ~50fps data from ov5640 using ffmpeg - CPU load 100%

Hey,
I haven't actually tried cedarx yet; planning to do so in the next few days. Did you obtain the 50fps h264 encoding result using CPU only (no cedarx)? That sounds pretty impressive.

niyazfattahov · 2021-07-25 16:26:48

@unturned3
No, I get such fps using hard codec using ffmpeg -c:v h264_omx , without cedarx I get ~ 25fps 640x480, I dont understand why so high cpu load when using cedarx

I also cannot encode 1280x720 and more due to ion memory allocation failure (I set CMA to 32MB as aodzip recommended)

How did you invoke ffmpeg? May I see the exact command? Because I'm not quite sure how to do it properly.

I just went through the trouble of changing my kernel from 5.10 to 5.4.35, and I'm about to downgrade buildroot from 2020.11 to 2020.08. Building ffmpeg with --enable-omx in buildroot 2020.11 gives me a missing header OMX_core.h error.

niyazfattahov · 2021-07-26 13:47:05

this is my custom buildroot defconfig, may be it can help you.
Do you select glibc in toolchain(not ulibc)?

我用buildroot 2020.02.1，Linux 5.4.35 编译好了 cedar 和 libcedarc，但是在编译 ffmpeg（带--enable-omx）的时候 buildroot 报错 "ERROR: OMX_Core.h not found"

有大佬遇到过这个问题吗？我是按照 aodzip github 上的指示来做的啊…… debug 了两天了都不知道哪里出了问题

@unturned3
一样的问题很头大

buildroot没勾选openmax

@unturned3

同样的问题，有人解决了吗？也有人试过播放mp4文件吗？命令是什么？

大佬，buildroot里没有 OpenMax 这个包啊？请问在哪里勾选呢

Can you encode 720p and higher resolution with cedarx?
