Handling OAuth for Video/Image/Tweet


Hello All,

I already asked this question and to be clear to everyone in this forum, I am opening a new topic an sorry for this.

Coming to my question, I have tried make a tweet/Upload a video/Image to twitter using Java,but faced issues with OAuth. Will the suggestions from this blog and other sources as well, I have used 3rd party sdk for the same.
But I am into a situation where I have to work with API only. Could you please suggest the best way for this and an example POST request with all the parameters including OAuth will be very helpful.
(An INIT request with all the parameters will be really helpful).

Using twrl to track this is a bit complex for be as I am not aware of curl.

Thanks and sorry for such a long and repetitive question.
