ERROR: requested format not available when try to download with new youtube itag

[shaybracha]

fail to download youtube video with itag higher than 100 (support ABR)

any idea?

thanks

[jaimeMF]

Currently itags higher than 46 haven't been added to the format list, it should be easy though.
Just one question, do they have better quality?

[jaimeMF]

There are some problems, for example when playing in 1080p the video and the audio are separated in two files, the audio has itag 141 and the video, 137. For getting a file that can be played with VLC you have to join the two files with ffmpeg. Is there any advantage of using those new itags?

[shaybracha]

@jaimeMF

yes
the quality is quiet better by far !!

the request for itag higher than 100 is since youtube switch to ABR (same as Netflix).therefore the video and audio in different itag.

could you advice how to add new itags to the format list?

Thanks

It's quite easy to add them, see this diff: https://gist.github.com/jaimeMF/3f10a0e1af733155992e
I have just added 137, but you can add all of them. For doing it well though, you'll have to add the extensions to _video_extensions and the resolution to _video_dimensions. Also it won't join the videos, doing that will require more work.

Could you explain what is ABR?

@jaimeMF
Thanks....i will try to add them
ABR=Adaptive Bit Rate...
youtube develope new mechanism to jump between resolution during video streaming according to the user bandwitdth.

so,if your bandwidth allows higher resolution,youtube will recognize it during the video and will change it.
video with itags higher than 100 works with ABR

hope it was helpful

You have to download the source code (youtube.py is in youtube_dl/extractor/), you can run it (if python.exe is in your path) as: python.exe -m youtube_dl URL ...

[shaybracha]

sorry for the miss knownledge

if edit youtube.py with the new itags.where should i locate this .py file in order to run youtube-dl?
mybe should i rename this youtube.py file?
Thanks

[jaimeMF]

Just follow these steps:

1. Download the source.
2. Edit the file youtube_dl/extractor/youtube.py
3. Then in cmd.exe (or PowerShell if you use it) cd info the source directory (where the folder youtube_dl and README.md are).
4. Then run python.exe -m youtube_dl URL {OTHER_OPTIONS}

We may add it, but it will require some work.

ERROR: Unable to download video webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:547)>

thanks (BTW:no changes in youtube.py file yet)

@shaybracha Can you open new issues for unrelated questions? Otherwise, it becomes incredibly hard to track the various discussions, and our bug tracker becomes useless.

It looks like someone is giving you an incorrect SSL certificate. I'd first investigate it unless you are aware of it (i.e. you're using a company proxy, your ISP is censoring youtube, or you've set up a debugging proxy). You can disable certificate validation with --no-check-certificate, but that means that whoever is intercepting your requests can read and modify them.

[shaybracha]

works fine

thanks and sorry

[jaimeMF]

fixed with #1279
