video Thumbnails for a video sharing site

[J Das]

Hello everyone here in CODERANCH , would someone please explain me the concept behind making a thumbnail image for a video file ??? Like in video sharing sites , when we upload a video the video file appears as a thumbnail view , how can i achieve this ??? I am doing a video file sharing project where i have finished uploading the files , but when i show these files they should appear in thumbnail view , i am stuck with this part... I am not using any FRAMEWORK , so if anyone can suggest me anything i would be greatly thankful to you..

There are numerous libraries that can read video formats (see https://coderanch.com/how-to/java/OtherOpenSourceProjectsFaq for links to many of them). You can use those to extract images (maybe the first one) for display purposes.

Thank you so much for your kind reply , but i am not getting the idea how to use these libraries into my project. I mean when uploading the video file how will i bind the library to extract a thumbnail image of that video ? Please ignore my dumbness if so..

You will need to select one or more of those libraries depending on which file formats you plan to support. Not all of the libraries support all formats. Then you use those libraries to extract those images that you wish to show as preview (for starters, maybe always use the first image).

Which sites have you visited? Which libraries have you chosen? Most of their respective sites should have enough documentation and example code to get you going. Just saying "I don't know how to proceed" isn't going to let us help you. Did what I said in my last post make any sense at all to you? If so, what *did* you understand?

Look Sir , I looked into the link you provided , and also searched for some other such similar sites; I have found FFMPEG to be some sort of a tool which would be able to solve my problem , but I have not found the process how should we start it , I mean to say that I am working on Netbeans , so do i have to import any libraries for FFMPEG or not ? If so how and where ?
