How to use:

  1. Select the video file you want to convert to gif.
  2. And then choose the start time and end time in the video that you want to convert to the gif. You can use the text box to fine tune the time for the region of the video.
  3. Change the fps value to specify how many frames a second that you want to have your gif to play at. The smaller the fps value is, the slower the animation will appear.
  4. If you don’t want all the frames, select from “use every x frames” drop down list to skip a few frames. Be aware that if you skip more frames, the faster the animation will appear. You’d better reduce the fps value to compensate for the frames you skipped here.
  5. Finally, use the drag bar to resize and set for the size of the final gif.
  6. Click the “Start” button to start create the gif, the gif will be auto named with the same name as your input video file and will be created in the same directory. If the conversion success, you can click on the file name to open the folder.

Cautious: The more frames you want to pack into the gif and the bigger size you specified for the gif, the longer time it will take to create the gif. So be prepared to wait for several minutes or even tens of minutes if this is your case.

Features:

  • drag and drop to specify the beginning and end of the video portion you want to convert to the gif
  • be able to fine tune the start and end of the video with text box
  • be able to specify the fps value that gif will be played back
  • be able to skip a few frames if not all that is useful
  • resize to the desired size for gif
  • preview of the frames
  • auto create the name of the gif file

Solution to missing mkstemp when you are compiling under mingw

Leave a reply

I googled around, doesn’t find a perfect solution. But I do come across 2 files on apple website, they actually implement the missing functions while dealing with the code ported to mingw.
http://www.opensource.apple.com/source/Git/Git-17/src/git/compat/mingw.h
http://www.opensource.apple.com/source/Git/Git-17/src/git/compat/mingw.c

For my scenario, I simply created a compiler based branch:
#if defined(__MINGW32__)

int mkstemp(char *template)
{
char *filename = mktemp(template);
if (filename == NULL)
return -1;
return open(filename, O_RDWR | O_CREAT, 0600);
}

#endif

I also downloaded and attached here in case could be useful later: mingw.zip

merge .net dlls into one with ILMerge

Leave a reply

If you hate to distribute many .net assemblies, then a tool I have just discovered might be of help: ILMerge, the url is: http://research.microsoft.com/en-us/people/mbarnett/ilmerge.aspx

But I don’t know a good solution that could do both obfuscation and dll merge. It’s always good to keep the stuff slim but also bug free without headache.

And good to know there is a tool called: apimonitor, http://www.rohitab.com/apimonitor, should to the thing as it’s name indicates which I always want to know about.

Datetime::Now is high precision time

Leave a reply

You can get the high precision time with Datetime::Now, instead of with complicated: QueryPerformanceCounter
The test code is:

for (int i=0; i< 20; i++)
{
Console::WriteLine(DateTime::Now.Ticks);
}

And this is the output:
datetime now ticks
It is precise to the 100 nanosecond as you can see from the above image.
