关于rtmp分辨率问题

junchao98 commented 2 months ago

在文档中的rtmp测试代码分辨率为640x480 ，尝试修改为更大的分辨率例如1920x1080，出现错误

参考的测试代码

from maix import camera, time, rtmp, image

cam = camera.Camera(640, 480, image.Format.FMT_YVU420SP)

# rtmp://192.168.0.30:1935/live/stream
host = '192.168.0.30'
port = 1935
app = 'live'
stream = 'stream'
bitrate = 1000_000
r = rtmp.Rtmp(host, port, app, stream, bitrate)
r.bind_camera(cam)
r.start()

while True:
    time.sleep(1)

报错信息如下，似乎是buffer空间不够。

在rtsp 测试用例中分辨率可以为2560x1440。请问rtmp分辨率的问题是软件bug还是受限于硬件资源

这个问题像是同时运行了两个APP,maixcam不允许多个app同时跑. rtmp是支持1920x1080的, 如果还是不行可以升级到最新的系统再尝试
