Suggestion option to dump only result, viz id, artist-title or error

[artofit]

While downloading a playlist one may encounter several issues such:

• one's artist-title does not correspond to the ouput
• errors

Those are very insteresting information, but a matching between the returned information from youtube-dl and your own can be lenghty process.

I propose to have an option (say -d summaryLog.txt) to dump a summary log unicode or UTF-8 text file with the following structure, for each videoID a single line as:
video_ID; either output name or occurred error

So instead of for instance:
F:\Youtube Extract\Russian>youtube-dl nG647q4Obds
[youtube] Setting language
[youtube] nG647q4Obds: Downloading webpage
[youtube] nG647q4Obds: Downloading video info webpage
[youtube] nG647q4Obds: Extracting video information
[youtube] nG647q4Obds: Encrypted signatures detected.
[download] Destination: - -nG647q4Obds.mp4
[download] 100% of 5.08MiB in 00:05

One would have:
nG647q4Obds; Инфинити - Таю-nG647q4Obds

Thanks

Can you elaborate on what an artist-title is and how you perform the matching? Without enough context of your problem, any implementation is unlikely to really solve your problem.

Well, I mean you may have created your own playlist, such as in a csv or xls file, with some column info such as
genre;artist;title;video_id

Now, when downloading a list of video_id, you may wish to control the downloads against your list, obviously the video_id is a good primary key choice.

By performing such a check you may notice basically 2 issues:
1/ the video_id does not correspond to what you expected from your list
2/ the video was not downloaded for some reason.

Dumping the result of a command such as:
youtube-dl -i -a listOfVid.txt
to an unicode/utf-8 text file having the structure:
video_od; either output name or occurred error

would make it easy to cross check against source playlist.
