X3PI多媒体接口问题

hr9654 · 2022 年12 月 8 日 01:59

第一个问题：

使用GC4663摄像头，在X3pi运行python实时推理例程，执行：

cam.open_cam(0, 1, 30, 2048,1024 )

img = cam.get_img(2,2048,1024)

img里面get不到数据，经测试open_cam分辨率设置要小于等于1920*1080才能正常运行，但是理论上400m摄像头应该可以设置更高的分辨率？-
第二个问题：-
运行test_cam_vps_display()例程报错如下

sudo python3 ./YUV2JPG.py

Camera open_cam return:0

如果把来自CAN的img存成文件，再从文件进行VPS操作则没问题，请问这个该怎么解决？

您好，报错表示IPU初始化失败及VPS启动失败，建议检查一下配置参数

zhenjian · 2022 年12 月 8 日 02:28

这个报错一般是IPU一路配置为offline输入，另一路配置为online输入导致的报错，这样是不支持的，不同路输入要一致，要么全online输入，要么全offline输入

hr9654 · 2022 年12 月 8 日 02:50

谢谢，IPU应该在哪里配置？

zhenjian · 2022 年12 月 8 日 04:37

这个场景应该ipu是vps的第一个模块，检查一下vin vps mode

hr9654 · 2022 年12 月 8 日 07:12

文档中没找到啊?，麻烦告诉一下怎么检查vin vps mode

zhenjian · 2022 年12 月 8 日 08:54

看了下您具体用的python接口，没有显式配置vin vps模式的接口，方便贴下kernel报错信息吗，dmesg可以看到对应出错时间的，看是否有"IPU DMA input already,can’t set otf input“"IPU otf input already,can’t set dma input”字样

zhenjian · 2022 年12 月 8 日 09:01

open_cam,open_vps的参数方便的话也贴下吧

hr9654 · 2022 年12 月 8 日 23:54

你好，dmeg信息如下，文字审核不过：

存在IPU otf input already,can’t set dma input字样；

cam和vps参数如下：

def test_cam_vps_display():

#camera start

cam = libsrcampy.Camera()

ret = cam.open_cam(0, 1, 30, [1920, 1280], [1080, 720])

print(“Camera open_cam return:%d” % ret)

#vps start

vps = libsrcampy.Camera()

ret = vps.open_vps(1, 1, 1920, 1080, 512, 512)

print(“Camera vps return:%d” % ret)

#display start

disp = libsrcampy.Display()

ret = disp.display(0, 1920, 1080, 0, 1)

print (“Display display 0 return:%d” % ret)

a = 0

while a < 100:

img = cam.get_img()

if img is not None:

vps.set_img(img)

print(“camera get image success count: %d” % a)

else:

print(“camera get image failed count: %d” % a)

img = vps.get_img(2, 1920, 1080)

if img is not None:

disp.set_img(img)

print(“vps get image success count: %d” % a)

else:

print(“vps get image failed count: %d” % a)

a = a + 1

disp.close()

vps.close_cam()

cam.close_cam()

print(“test_cam_vps_display done!!!”)

看报错的话确实是第一路配置了online，第二路offline导致初始化失败，据了解python接口目前不支持您当前的用法
