Hi people.
I need to know how may I detect frame rate of a video file in VB.NET?

What I have tried:

I just found some articles they did this via FFMPEG and FFPROBE. But I found no luck with them. Also I don't like to use process to run shell file.

Try GitHub - mono/taglib-sharp: Library for reading and writing metadata in media files[^]

@M-Badger
TagLib does not show frame rate.

You're right in that it's not required in the metadata, which is what taglib-sharp reads, but it can be - depends on what your needs are.
You could also look at https://github.com/radek-k/FFMediaToolkit
Or https://www.visioforge.com/help/

I checked taglib-sharp also. I doesn't give me frame rate.
Could you please kindly help me on this and let me know its code to determine frame rate with taglib-sharp ?
Thanks

taglib-sharp can recover the frame rate from the meta data IF AND ONLY IF it is included in the metadata - so those formats that allow optional information like ID3v2 does for mp3.
I have given you two other alternatives, FFMediaToolkit and Visio Forge. Try them.

Thanks for alternatives, but they are not open source. Actually I am looking for code. I mean a low-level code without using third parties or components or external files.
