The issue:
Let's say, we have started downloading the video(music). The music file has been created and content are writing to this file. But something wrong has happend(user destroy the application or the device has gone off) and the music file hasn't been finished(Not all content are loaded).

Solution:
Add a mechanism that checks the downloaded files whether they were fully downloaded.
If not, remove the old(broken) file and download again

Progress bar has been already added to each item while they are downloading.
But need to add progress of size in bytes(for example 6452/23542 bytes)

The bug that caused in the library YouTubeDownloader has been already fixed.
Just update to the nearest version of the library.
Besides remove the custom parser that actually is the same as the default parser.
Explanation: Custom parser was created because I fixed a little but significant bug there.
As mentioned above just update to the newest version.
