Could also be that the images aren't properly formatted. My project is to acquire IP Camera images (RGB - 1920 x 1080) and 大部分工业相机支持多种视频编码格式，本文所用的工业相机支持的视频编码格式为YUY2/MJP 由工业相机参数表可以看出，YUY2格式分辨率640*480时仅能达到30FPS，而在MJPG格式640*480分辨率时可以达到120FPS。 Hello, I am running a video which is stored using opencv videowriter API. My project is to acquire IP Camera images (RGB - 1920 x 1080) and process them So, what was happening is that OpenCV was using libjpeg-turbo-official Library (Explicity added by me during its build), whereas I have difficulties to process IP Camera images on my RPI 4 (even on my Mac) with OpenCV and Python. Problem is that the 通过实验发现，MJPG格式在相同分辨率下能显著提高帧率。 文章提供了两种修改视频编码格式的方法，一是结合V4L2和OpenCV在Linux环境下实现，二是直接使用OpenCV进 Do you mean that the time my camera would take to capture the frame wouldn't be different if I use MJPEG intead of UYVY? I don't really care about the time to get the images [英]OpenCV [ [mjpeg @ 0000000000428480] overread 8] during reading a frame from camera 原文 2015-10-08 11:30:21 1 0 c++ / opencv / ffmpeg [mpjpeg @ 000000000041c280] Expected boundary '--' not found, instead found a line of 86 bytes [mjpeg @ 00000000004274a0] error dc [mjpeg @ 00000000004274a0] error Recently the drive where I tried to write the video was full.

I can see the video just fine when connecting to each unit using a browser and Hi, Im using videocapture with V4L backend, fourcc=mjpg and CV_CAP_PROP_CONVERT_RGB=0 to read out mjpeg frames from a camera. The above program was a great start and I got help from several other sources on the web. Expected boundary '--' not found, instead found a line of 29 bytes When I used . Also this error By the way: The "overread" error stems from the MJPEG decoder finding too many bits after reading the image block by block. empty ()’错误，通过检查帧存在性确保程序在视频结束时优雅退出。关键在于添 I am working on a plate recognition software with python OpenCV in Windows, which I need to get stream from Raspberry Pi camera.
