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

What is the purpose of video only files?
This has the potential advantages of easier management and reduced space required on the server and also gives the client the ability to change audio choice without having to download any video again.
Re the space saving if the video and audio were pre-combined on the server then to give the same flexibility the server would need to have multiple versions of the same video where the only difference is the audio tracks.

For some examples see
https://medium.com/canal-tech/how-video-streaming-works-on-the-web-an-introduction-7919739f7e1
 
Throwing in my two penn'orth, it doesn't seem to have been mentioned above that including the --restrict-filenames command to limit filenames to ASCII will make sure you don't get the "Cannot support this file format" message when playing them on the HDR.

(I'm not using youtube-dl on the HDR, I'm using it with Youtube-DLG to download to a shared drive on a Windows PC.)

Well I got it to work, not an easy feat for me, I used this command youtube https://www.bbc.co.uk/iplayer/episode/b07c6fjk/louis-theroux-a-different-brain#
When the video is played back on my box, the picture flickers - stutters. Is there anything I can do about it.
Here is the output of the CLI.

When the video is played back on my box, the picture flickers - stutters. Is there anything I can do about it.
I've never found a problem playing these downloads, although I do restrict the quality and you have defaulted to the HiDef download.

Whether you can do anything about it depends what's causing it. It could be that your HDD has errors/faults, and that might cause glitches but you should expect the same on other recordings (especially high-bandwidth HiDef recordings). If it's a faulty download the only thing you can do is try again (but try lower quality).
 
Turned out later that evening lip sync was out too. The next day all is good, so I don't know if the box was doing stuff at the same time and it was running slow.

I'm not sure if there is a time / file size limit on downloads, but I recently got an Error 403 half way throught a 14.23GiB download, I have a slow broadband connection and the 8GiB I managed to get before the 'Error' took about 5 hours and plays fine with no sound due to the incomplete download, details below :-

You should just be able to restart it. I suspect a server side problem rather than client side.
Why are you using the 4K download anyway? I'd have thought "137+140" more appropriate.

I recently purchased a 4K tv and at the moment have little content to view

EDIT
Great suggestion, even though I have renamed - copied - and then deleted the file from the Humax, after copying it back and renaming it back to *.webm.part, did indeed allow the download to resume, only another 5 - 6 - 7 hours to go :) :-

How are you expecting to get it to the TV? The HDMI from the Humax won't do it. Maybe DLNA? Or something else?

Like every smart TV I've seen in the last 10 years it has a USB port that plays video directly from a HDD, DLNA does also work from the Humax, although currently the TV is in a bedroom without wired LAN, so it is connecting via WiFi to the Humax (also on Wifi in the same bedroom), so 4K streaming does occasionally break up

BTW
The 2hour 10 min video I downloaded appears to have multiple copies of the same videos, so I probably got all I needed in the first partial download anyway, but hey, it worked

Thank you! What a brilliant example of collaboration this project has become.
Always was.

Am I not right in thinking that without af123, there wouldn’t even be custom firmware of any description, (and not only for the Fox T2 but also for the Foxsat)?
Not entirely. See Glossary (click), entry BYTs.

However, it is true that af123 has (and developed) the skills and did the "heavy lifting", with some collaboration and encouragement along the way. Otherwise it would have been a very lonely task.
