I guess this now means it's downloaded the JSON, but it seems to need something similar for the video:

--external-downloader wget should work for this page.

--external-downloader ffmpeg should also work and would also be able to download some manifest links (.m3u8) as with the Vera test episode https://www.itv.com/watch/vera/1a7314/1a7314a0014 9id from the extractor.

Non-downloadable manifests would be those that use obfuscation not handled by the CF build of ffmpeg.

In fact, the option combination --external-downloader wget --hls-prefer-ffmpeg should cover most TLS download requirements. DASH, ISM and F4M manifests use the built-in HTTP downloader, so videos from a site that serves, eg, DASH segments with a TLS version too high for CF Python won't be downloadable. Other download types would use a different external downloader (eg rtmp).

Both of those work.

What does that cover? BBC, ITV and Youtube would seem to be mainly our use. Can those options be used for all of those, or do they just need to be used for ITV?

It should be possible to make those options a default. Although BBC doesn't make a fuss about TLS versions; YT may well do, even if it doesn't now, and ITV definitely does (as above). The only negative is that an additional wget process may be used instead of the internal downloader when the latter would have been able to cope (eg, BBC MP4s).

As updated above, some sites may serve DASH manifests whose segments yt-dl can't download, without rebuilding CF Python.

Some builds of ffmpeg supposedly support DASH, but no CF versions, and yt-dl assumes that ffmpeg can't handle a DASH manifest.

Also, a new build is recommended as we/YouTube broke YouTube extraction a couple of weeks ago. The latest git master is good.

In fact, the option combination --external-downloader wget --hls-prefer-ffmpeg should cover most TLS download requirements.
Using that with iPlayer results in absolutely endless whining messages about timestamps and a download rate about 40% of what you get if you omit the --hls-prefer-ffmpeg option (12:53 vs. 32:11 on the 1800 news).

No, YT started sending a new uploader URL format that causes the crash (ERROR: ...), owing to a latent bug. Fixed in upstream repo. Also fixed in the latest extractor version, YT started a new rate throttling scheme and a bug in the existing unthrottling code (WARNING: ...) was exposed. I'll shortly push a couple of related fixes, but the current upstream code is fine, especially if you get a combined format (-f best, eg).

In this log there is a Humax packaging issue too. yt-dl is trying to cache data extracted from the YT player JS (2MB of unwanted bloat every time, Invidious FTW). But there's no cache directory:
Code:
       --cache-dir DIR
              Location in the filesystem where youtube-dl can store some down‐
              loaded      information      permanently.       By       default
              $XDG_CACHE_HOME/youtube-dl  or ~/.cache/youtube-dl .  ...
So, depending on how ~ resolves, the default locations in Humax CF are /youtube-dl, /mod/.cache/youtube-dl or ./.cache/youtube-dl.

The default config needs this line, which can be added in the qtube options field for now (my spies say that the directory is created when needed):
Code:
--cache-dir /mod/var/cache/youtube-dl
Or export this setting system-wide: XDG_CACHE_HOME=/mod/var/cache

Confirmed. The troublesome download now succeeds on both HDR-FOX and HD-FOX after an auto-update (without any intervention from me other than resubmitting the failed queue item). Thanks both.

If one wanted to abort a background download, how would one do it? It's not possible to delete a queue item if it's already running.

Manual process killing. Or reboot and delete/hold the item in the queue before it restarts. I think you have a few minutes (4 or 5).
It's not possible to delete a queue item if it's already running.
This is somewhat irritating. Sometimes it says something's running when it isn't, and there's no easy way out.

It should probably save the PID when starting a queued task and use that to allow killing of a running task and to detect whether a queued item is really still running
 
Are there any up-to-date instructions for how to install the youtube-dl package? It's not listed in the "Available" list in the web IF, and the instructions from Github give this error:
Code:
humax# wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl
