ValueError: time data '' does not match format '%Y%m%d'

[usagicore]

using version 2015.12.13
#772 looks similar but thats old and mine does not print any time data.

also tried other videos without proxy.

python3 /tmp/mnt/usb/scripts/youtube-dl --proxy "157.7.242.91:8080" --no-check-certificate -f 22 https://www.youtube.com/watch?v=eRp6kHSbdN8

I got the very same issue here (for all videos on youtube), but I have managed to fix it.
Around line 610 in YoutubeDL.py comment out the following 2 lines:

lassuviz null date fix

if date not in dateRange:

return '%s upload date is not in range %s' % (date_from_str(date).isoformat(), dateRange)

Apply these 2 # and youtube-dl will start to download videos !!!

I am not sure if it has side-effect for special download cases (ie. daterange), but works well flawlessly on normal and playlist download on youtube. :)

I am not python expert, nor familiar with the internals of youtube-dl but I think some system (including mine) supplies/parses date in a wrong manner.

If someone could make this null date fix properly on the code-base (regarding my finding) I would be very happy, because I just love youtube-dl project. It is just great!

I guess this is caused by broken wcsftime in libc. See #9557 for how to check libc. Feel free to leave a comment if your libc is working while youtube-dl not.
