Thanks for your quick and detailed answer, even if my application will not

selected, I have already learnt a lot of useful and interesting things!

I have improperly used that word, it have changed it with "improved" that I
believe more suitable.

Thank you, without your hints it would have still been too poor for a
contest
like GSoC.

I improved these sections and I decided to include for each week of the
timeline
a clear level of availability that I am going to have.

Obviously it was not done on purpose. I have added it among the candidates.

I am thinking to write a little library in Python to manage this file

As you said the Python Wrapper is not useful, even with the RFP.
What do you think about interacting directly with ffmpeg library (without
wrappers) ?

Great hint, I agree with you and I changed the schedule. You can find
another version of the proposal in this mail.

Thank you again.
