RK3568J安装官方ubuntu固件无法运行ffmedia的demo小白求助
使用RK3568J开发板安装官方ubuntu固件后无法运行ffmedia的demo，固件安装后系统信息如下:OS: Ubuntu 20.04.6 LTS
MODEL: AIO-3568J HDMI (Linux)
FIREFLY: v3.10-8-gdbbe44f6
DATE: 20240111
KERNEL:Linux version 4.19.232 (lanzj@tchip14) (rk356x/firefly: 50ce91e4819b9979ae6371d22f2edd59e09bce5c) (sdk version: rk356x_linux_release_20240109_v1.3.2g.xml) (gcc version 10.3.1 20210621 (GNU Toolchain for the A-profile Architecture 10.3-2021.07 (arm-10.29)), GNU ld (GNU Toolchain for the A-profile Architecture 10.3-2021.07 (arm-10.29)) 2.36.1.20210621) #2 SMP Wed Jan 10 11:40:40 CST 2024
ffmedia是克隆https://gitlab.com/firefly-linux/ffmedia_release.git后编译的。
现在问题是使用demo进行播放 demo /usr/local/test.mp4 -o 1280x720 -x 0执行时显示信息如下：
Firefly FFMedia: v2.2.4
INFO: ff_media: start_instance:

并且会产生一个绿屏并保持,请问是什么原因呢？
还有我运行它的拉流解码demo_simple时报错:
./demo_simple

使用的流地址我使用ffplay测试过是正常的,为什么会出现这个问题？求解答。
你的板子内存规格应该是大于4g的，通过限制drm申请内存在4g之内解决：
diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_gem.c b/drivers/gpu/drm/rockchip/rockchip_drm_gem.c
index 946d8e364469..29700e55b4a3 100644
--- a/drivers/gpu/drm/rockchip/rockchip_drm_gem.c
+++ b/drivers/gpu/drm/rockchip/rockchip_drm_gem.c

内核打上该补丁，重新编译、烧入。 dengkx 发表于 2024-4-25 19:01

谢谢大佬解答，我的开发板的确是8G的,我马上试试。我还有一个问题想请教,ffmedia支持多路视频分析推理吗?就类似deepstream那样,我看提供的demo只是对一个视频流的推理分析。 law 发表于 2024-4-26 08:52

支持，多路就多创建几条模块链路 dengkx 发表于 2024-4-26 09:35

可以batch化推理吗
