[youtube-dl] Download files from youtube.com or other video platforms

You won't see the output properly unless you run the command at a terminal prompt. yt-dl treats anything that looks like a YT video ID as the equivalent YT URL. cd to the directory where the video should be saved beforehand.

Possibly your home network is IPv6-aware and the downloader is getting confused by an unexpected IPv6 address (or vice versa). The -4 and -6 options tell yt-dl to stick to each one. Without checking I can't recall what effect these have in the master code but ISTR passing them into the wget-based downloader used in the CF version.
 
I'm playing off-site with a supported user's HDR with a new BT digital-only service so IPv6 might be a thing. Just applying your options in qtube crashed and burned with the same "not supported by protocol" message embedded in a load of dubug.

I can try it again on the command line if that's of use.

Above IPv6 is being returned but it doesn't affect the result. The CF wget doesn't know about IPv6 (but strangely doesn't limit IPv6 when resolving, or strip out IPv6 from the query result -- there should be a build option that would force that; do Foxes-T2 support IPv6 at all?), so it gives up and uses the IPv4 address, which works. -4 (same option for wget and yt-dl: how did that happen?) causes the IPv4 address to be used with no warning message.

In your log, a worse problem occurs, where the download command gets 404. Maybe the code that calls wget is confused. What happens with youtube-dl -4 ...?

Will it work just using pc/laptop/computer to download?
Ie. Is it an issue with the Humax version/code or is it an issue with the other end?
Sorry, I think @/df managed it ok.
 
YT has changed the available formats. Possibly yt-dl format selection is now finding DASH formats instead of unfragmented formats and so causing this problem.

Try --external-downloader ffmpeg. The WgetFD external downloader is marked as supporting the default protocols 'http', 'https', 'ftp', 'ftps', so for DASH the internal default is used, which may be a bad thing, in a way that I'd have to debug to explain. FFmpegFD also supports 'http_dash_segments' and so is used.

You could exclude DASH formats altogether (YT only) with --youtube-skip-dash-manifest, or filter them out in the format selection (less efficient but would work for any site). However HLS formats, which might be selected if DASH aren't available, also need --external-downloader ffmpeg.
 
Not sure if this will help (or maybe provide some clues for youtube-dl)

Edit1: I think adapting an old method with @/df's suggestion
youtube-dl -4 -F ..
followed by
youtube-dl -4 -f 137+140 .. or youtube-dl -4 -f 136+140 ..
should work.

The process did't fail, but resulted in a download of only 262 bytes!

I give up, I'll see what I can do at home. Thanks for the pointers.
 
Still not having any luck with this. I've tried it with yt-dlp on my Mint machine, I presume the command line options are the same, but that comes back saying the packets are larger than expected!
 
I have found I can download the video component using -f 160, which is at the original resolution 256x144. The audio component is 140. What config do I need to download both 160 and 140 and combine them?

Edit: Belay that. The question still stands, as it would be useful to know (and I'll add it to the guide), but there is something severely wrong with the product of -f 160.

YT made some changes on Wednesday that broke YT-DLP which was updated to deal with it yesterday (Thursday). I presume other YT downloaders were affected too.

Click to expand...
Whenever I have done this kind of thing on a PC I would use (in your example): -f 160+140

It is important that the video component is the first one specified.
The downloads are done to separate files, combined afterwards by YT-DLP to a new file and the originals deleted.
I think it is that simple - or am I missing something?
 
This is really a question solved by RTFM.

Basically, the default format selection in the base product, when not piping the output, is bestvideo+bestaudio/best; the matching stream(s) are downloaded and, if necessary and as long as ffmpeg is available, merged; retention of intermediate files is an option.

yt-dlp has a useful -S ... option to change the priority of available formats (ie, what does best... mean). With youtube-dl, it's recommended to specify what formats you want in a specific format selection option, possibly with fallback selections separated by /.
 
Not very knowledgeable user updated to youtube-dl version 2024.08.01 today. Unable to get YT videos seemingly because player bd3293c9 is not found. I ran youtube-dl with -v -F Extracts here:

[debug] [youtube] Extracting signature function js_bd3293c9_108

ERROR: Unable to extract nsig function code (caused by RegexNotFoundError(u'Unable to extract \x1b[0;34mInitial JS player n function name\x1b[0m; please report this issue ...

Which looks similar but different to the issue fixed on git last week
 
They changed things again yesterday so 'download as highest MP4' would download as 4K VP90 (3840x2160) with no sound and today there's a new YT-DLG that fixes it.
