--ignore-errors option doesn't work properly

[akulovz]

Hello.

Due to my weak internet connection youtube-dl rather often stops with errors like

ERROR: Unable to download webpage: <urlopen error [Errno 8] _ssl.c:510: EOF occurred in violation of protocol> (caused by URLError(SSLError(8, '_ssl.c:510: EOF occurred in violation of protocol'),))

or

ERROR: content too short (expected 54847647 bytes and served 1977491)

or

ERROR: Unable to download webpage: <urlopen error Tunnel connection failed: 503 Service Unavailable> (caused by URLError(error('Tunnel connection failed: 503 Service Unavailable',),))

or things like that. Even I use --ignore-errors option.

So I have to wrap youtube-dl with bash. Say, I want to get a best quality video from Youtube:
until [ -e *"$PREFIX"\.mp4 ] ; do youtube-dl "$PREFIX" ; done

But a problem appears with batch file containing URLs or prefixes for download — I can't guess an extention for downloaded file so wrapper continues downloading an only file till I stop it.

Is there a way to fix it without branchyspreading shell-scripting?

Just to clarify: --ignore-errors ignores individual video errors in playlists. Errors in single videos are still respected.
For your case, I guess using [ ! -e *.part ] is enough.

Thank you for your reply, Yen.

But your code example won't work as when download starts, the *.part file doesn't exist yet.

So I have to wrap batch youtube downloads with this code:

while read PREFIX QUALITY FORMAT
  do until [ -e *"$PREFIX"\."$FORMAT" ]
    do youtube-dl --recode-video "$FORMAT" http\:\/\/youtu\.be\/"$PREFIX" -f "$QUALITY"
    done
  done < tube

where tube is three-fielded file with needed prefix in first field and quality and file format in the others like this:

qsWl1--Niyg best mp4
Med2XipHJJM best mp4
rqSF_9Zf0n4 best mkv
ogNr078W2HA worst webm
_k_pqFSVFxI worst flv

I guess this is the only way to make youtube-dl ignore all errors. :sigh:

Anyway, thank you for your work and great software!
