Cannot find RIMIDEWin32Util.dll in Eclipse for Blackberry development

I switched to Windows 7 64 bit few months back and I upgraded all my tools/SDKs to 64 bit versions including JDK. Suddenly after I updated JDK to 64bit my Eclipse plugin that I use to develop Blackberry applications started giving this error on every start

Cannot find RIMIDEWin32Util.dll. This is a required component of the IDE.

Solution to this problem is that install both JDK and Eclipse 32bit versions. And set the following environment variables in Windows

JAVAHOME=path to the folder where JDK(32bit) is installed

PATH=add path to bin folder of your JDK(32bit)

Decoding JPEG image file using libavcodec

I got a chance to work on a video encoding application that decodes series of jpeg files and convert them into ogg theora video file. I used the infamous libavcodec library that is used in FFMPEG . I decided to write blog posts explaining how I decode jpeg images and convert them into ogg video file. This is the first part and in this I will explain how to decode jpeg images using libavcodec. To learn how to write decoded images as a ogg video file please read http://random-stuff-mine.blogspot.com/2017/07/encoding-raw-images-to-ogg-theora-video.html Before reading this blog post you must be aware of using and setting up libavcodec. I highly recommend this tutorial to get basics of using libavcodec http://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html Allocating input format context We will first allocate input format for reading the file. We will use avformat_open_input function that will allocate AVFormatContext structure passed to it , the function detects input typ

CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information

I created a new Blazor Server app in Visual Studio 2019 and tried to run it. But I was getting this error CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information. I couldn't find any reason or solution to this problem. I tried creating the project multiple times but same error. I created a new .Net Core Web App and added a new razor component and included that component in a razor page (cshtml file) like this @(await Html.RenderComponentAsync<GeofenceWork>(RenderMode.ServerPrerendered)) and <component type="typeof(GeofenceWork)" render-mode="serverprerendered" /> As soon as I navigate to this page that has component added I got the same error: CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information. This was very frustrating. After hours of trying and searching I figured out the solution.

Encoding raw images to Ogg Theora video using libavcodec

In one of the blog posts we learned how to decode jpeg images using libavcodec. This is the second part of that post. In this we will learn how to encode decoded images (raw images) to theora and write them in ogg video file. In the end of the first part we saved our raw image in raw_data variable and its length in raw_data_size variable. Lets assume that we packaged all our decoding code in one function called "decode_jpeg_image" which has following signature int decode_jpeg_image(char *filename,int file_name_size,uint8_t *raw_data,int *raw_data_size) filename = name of jpeg file to decode file_name_size = length of jpeg file's name raw_data = contains decoded raw image on return raw_data_size = contains length of raw_data on return Now let's start working on how to encode this image in raw_data to theora and write that image to ogg video file. Finding Theora encoder We first have to find encoder for THEORA which is represented by AVCodec structure. He
