Channel 4 downloader

[naim2007]

I couldn't find a working C4 script so I wrote my own - https://github.com/Diazole/c4-dl.

Forgive my ignorance as I'm new to using youtube-dl etc but I would like to learn how to download videos from Channel 4. I've downloaded the zip from GitHub but I'm clueless as to how to install and use. Is there some instructions or a video, or something I should be reading to get started? I'm a software developer by trade so not totally alien to scripting but as I said this is new to me.

try to follow this methode, i's worked for me as well

can anyone help me im getting this error

im getting this now:

I have my own solutions for ITVX, All4, CH5, UKTV, RTE, Discovery+, STV (encrypted) which I've automated with extra script as much as possible and I've been pretty happy with (they work lol). They are based on the original WKS-KEYS but with some modifications. They do require some manual input like mpd, licence, PSSH (for Britbox/ ITVX), and copying cURL to Python for All4 and Disc+. None of these use this "new" pywidevine module.

So, I thought I'd look at this all-in-one solution for All4. I installed the said pywidevine module. Well, that didn't go too well lol. My ITVX and STV solutions stopped working (came up with errors). It seems that the problem is installing pywidevine also updates already installed modules (like protobuf). The older scripts don't like these latest versions.

Fortunately, I have a backup of my Scripts and site-packages folders, so it was easy to reverse the situation.

Been there too, see the end of this post under 'Gotchas' https://forum.videohelp.com/threads/407216-Decryption-The-Dungeon-of-Despair#post2669281

If you get caught this way and you want to use WKS_KEYS then remove protofub 4.x.x (pip uninstall protobuf) and run pip install 'protobuf==3.20.3' to install this older version.

I'm able to use both WKS and Diazole's script by renaming the pywidevine directory in WKS and also the pywidevine imports in all the WKS py files into "pywdv"
can't remember if there were problems with protobufs

[achilles]

First of all, thank you Diazole for this script. I've learned a ton going through it.

Just a minor caution for those using it. Some channel 4 shows have a descriptive audio track and this script grabs the "ba" best audio by default. For me, this usually meant it grabbed the descriptive audio track. So, I just changed it to "audio=128000" which is the regular English track.

And for anyone interested in subtitles, you can add a snippet to get_vod_stream() to find it. This example tries to find the associated .vtt. Other formats are available too, but not all shows have all formats. But I found that most shows had a .vtt so that is what I look for.

        for i in resp['subtitlesAssets']:
            if (os.path.splitext(i['url'])[1]==".vtt"):
                print(i['url'])

If wish the script could find the 5000Kbs streams, but that's a much bigger project and I think I need to learn a lot more stuff before I can do that.

someone talked about it here and the gist seems to be that those streams are for smart tvs
maybe you could spoof a smart tv through android studio(?) or some other emulator and then use http toolkit to look at the traffic when accessing a show and see if there's some kind of token or whatever that gets sent to unlock a better stream

Good spot on the descriptive audio track, unfortunately "audio=128000" won't work in all scenarios as the name of the audio track isn't always the same. I think it's better, albeit hacky, to set a regex on the audio, "ba[language~="[a-z-Z]{0,0}"]", unless someone has a better idea.

I've managed to figure out how to get the 5000kbps stream so i'll update the script once i've finished testing.

[A_n_g_e_l_a]

I've managed to figure out how to get the 5000kbps stream so i'll update the script once i've finished testing.

    #wa ~worst-audio needed as channel4 ba downloads a narration audio version for visually impaired.
    os.system(f"yt-dlp --allow-u -f wa -o 'encryptAud.%(ext)s' {url}")

I have this in my channel4 script that uses WKS-KEYS. It works.

[lcsneil]

I also use worstaudio and to date have never had an issue. As previously commented using bestaudio gets you the AD track.

I don't think that's any better because you could potentially download a lower bit rate audio stream?

The reason "ba" grabs the descriptive audio track is because yt-dlp sorts by lang to figure out the best audio. The descriptive stream has lang="en" whereas the normal stream does not.

The correct way would be to make yt-dlp check the Role node as that contains whether the stream is descriptive or not, but I don't think yt-dlp supports that.

Normal:

<Role schemeIdUri="urn:mpeg:dash:role:2011" value="main" />

Descriptive:

<Role schemeIdUri="urn:mpeg:dash:role:2011" value="description" />

are u gonna update the script and post it here? please? or can u update and send me the script to try please

No the reason ba grabs the descriptive track is because it is the last audio track, just the same as best video is the last in the list.

I'm a pragmatist. and If you feel the need to spend hours looking at ways of ensuring you don't get the descriptive track go ahead and over-engineer.

Whenever I've looked at channel4 - and I don't these day because someone gave me a damn-good downloader - I only saw two audio tracks.

Doing the correct thing isn't overengineering, selecting the worst audio quality will work whilst there are only two audio streams, but it's far from ideal.

Whenever I've looked at channel4 - and I don't these day because someone gave me a damn-good downloader - I only saw two audio tracks.

What makes this channel4 downloader you speak of so "damn-good"? Care to share it with the community?

[bamboobali]

Thanks for the heads up about the 5000kbps support. Incidentally, I've always used a different bodge for the audio when an AD track/channel is present: "ba.2", but I might switch to the regex approach.

I've updated the script to grab the highest bitrate stream, the highest I've seen so far is 6000kbps.

I did some testing and found that C4 isn't consistent with the language attribute so my previous comment about using a regex to check the length isn't 100% effective. I also tried "ba.2" during my testing but I found that not every MPD has multiple streams (not all episodes support AD), so this isn't 100% effective either.

I've resorted to "wa" which isn't great. The actual fix would be to make yt-dl expose the "Role" node so we can filter on "value".

You probably have multiple crypto packages installed, run the following and use python 3 to run the script.

pip3 uninstall crypto 
pip3 uninstall pycrypto

N_m3u8DL-RE seems to pick the correct audio track automatically, so that's another option:

It doesn't.

Run:

pip uninstall pywidevine
pip install 'pywidevine==1.4.3'

so i downloaded it from github and added it manually and getting:

You've fixed your Crypto and pywidevine errors but now you're providing the script with the wrong URL.

The URL needs to be the URL of the episode you are trying to DL, e.g.

--url "https://www.channel4.com/programmes/the-big-bang-theory/on-demand/44564-001"

I tried the update and it works for me no problem. Great work!

Just two things:

1. Believe it or not, for some shows, the browser manifest actually contains higher bitrate streams than the android device manifest. So, ideally, the script should have a toggle to select either the browser or android manifest rather than ripping the old code out completely. Or even better, it tries both and finds the one with the highest bitrate but that's maybe more work than required. Ultimately, it's not a big deal, a person could just keep the old script lying around but it you make further edits in the future, it could cause a versioning problem.

2. I found that some shows with very long names caused a file too long problem and crapped out of yt-dlp/aria2c. I think this is partly because you write temporary files to a directory with the full show title and episode name, etc. When I hard coded the output file name to "episode" or something short, it worked no problem. So, a toggle to override the automated naming would be nice. It's not a deal breaker, just an ease of use improvement more than anything else. I'm surprised you never ran into this as some shows have ridiculously long names like "this is the show name: and then this some more text that goes after the colon".

But overall, thanks for the update!
