2017-07-08 11:11:10 -0600 | commented question | custom codec I am facing a similar issue. I am using OpenCV 2.4.13.2 build on Visual Studio 2008. I have to open a video file which is created with a custom code Delphi Jpeg IP. OpenCV 's VideoCapture is not able to open the file. Open return failure. Can anyone help. I was thinking of checking the possibility of making FFMPEG to support my codec. Any thoughts on that from anyone |

2017-07-08 09:36:20 -0600 | commented question | OpenCV2.2 with Visual Studio 2008 Hi, Now i realized the issue with the file opening is not related to the version of OpenCV. The file that i was trying to open was created with a Custom Codec known as DJIP. I tried with a downloaded avi file and that was working. Now i need to know how can i open or add support to a custom codec generated video file. I read somewhere that the Videos are open using ffmpeg. Thanks AJAI |
2017-07-08 09:02:35 -0600 | asked a question | How to make opencv support custom codes for videos for reading Hi, I wrote a small test sample program to open an avi file. The program is as show when i tried to open the file, it is always failing. I tried another file downloaded from the internet and that successfully opened. It is because the file that i was initially trying to open is created with a custom code and the second one( which opened successfully), was written with a codec IV41. I want to know how can i make my OpenCV to support custom built codecs. |

In debug when i tried to run the application it wasnt showing any exception but the value of the obj and refcount are 0s. I tried to create the debug information in Release. When i removed the debug information, its not giving any exception. But the values is same in the Debug. Thanks AJAI |
2017-05-18 02:13:39 -0600 | asked a question | OpenCV2.2 with Visual Studio 2008 I am very new to OpenCV. I downloaded and installed Open CV according to the instructions in the link https://rangadabarera.wordpress.com/o... . My requirement is to create a video library that can be used to replace the existing video library that uses Video For Windows(VFW). I am trying to write a sample code to open and read an avi file. I added the following libraries "opencv_core220.lib opencv_highgui220.lib opencv_video220.lib opencv_ffmpeg220.lib". The code i have written looks like as follows But while running the code, i am getting an exception with the following text Unhandled exception at 0x00905a4d in aviread.exe: 0xC0000005: Access violation. The value of the obj and referance count fields within the VideoCapture object seems to be 0 I tried another version like as follows and the output is the same But when i tried to to read from a camera, it seems like not throwing any error. The code is as follows int main() { string filename ("C:\ADAS_AHBC_201046_002.avi") ; While debugging this code, my lap's camera is getting invoked. Can you please help me understand as what is wrong with what i am doing. Thanks AJAI |
