[release] AllHellGui

[A_n_g_e_l_a]

I also ventured into the world of Python. Cool GUI you've built there, A_n_g_e_l_a! I played around with it a bit and now I'm getting the following message. It seems like there are 208 fragments, but it's asking me for 209. How can that be? I've used both Firefox and Opera to rule out any errors there.

That's an n_m3u8DL-RE error and there's a switch command you can set.... --help has it. Or use the Dash-mpd-cli downloader

Its better you create a separate thread regarding this problem because it has nothing to do with angela’s script
And please provide the command you used and links to the video
Good luc

[Blacksprite]

The switch command was the hint I needed. That still works in that case. Thx a lot.

Good on MalMen for trying to take his extension project forward.

For those that prefer a vanilla approach, and there is something to be said for remembering how to extract mpd and license from a site, I have, today, updated and simplified the HellYes offering on github https://github.com/vinefeeder/HellYes.

The change is to the methods of installation and use, plus some script duplicate removal.
There are additional binary installation scripts for Linux and Windows which find sources for support programs, install and add to your system's PATH. (Or you can still do hand installation, should you wish.)

The big change is that UV is now the package manager; so the software is started by:-
uv run gui.py -- for the Graphical Interface
uv run allhell3.py -- for the command line interface.
(Other start scripts have been removed - they became confusing)

Dash-mpd-cli (https://github.com/emarsden/dash-mpd-cli) was updated last week. The script installs the latest version

The README has been adjusted to reflect changes.

If anyone should want the original version it is the one still linked in my signature

Hi Angela,

thank you for your script, i have a question, i tested it right now and i dont understand everything perfect so maybe its a mistake on my side but i will get this error message when i press "Downlaod DASH"

Can you maybe help me? Would be awesome.

You are missing an element for the command so this is why you are showing an error in subprocess.

here is a part to check if a part is missing in the command and also in subprocess.

[Kimble89]

But i did not change any codes lines in the script from Angela. I use the gui version and just press the "Downlaod DASH" button. So this means there is an error in the script from Angela or?
I really dont know much about scripting so i also dont know what to do with your script? I entered in in Powershell but only get errors like in Python too

[Obo]

Either N_m3u8DL-RE or dash-mpd-cli are not executable by HellYesGui because they are not in PATH (or the dir where HellYesGui resides). It's not a bug in Angela's app, it's presumably an error in your setup.

[Kimble89]

Yes, it's highly likely that it's my fault
I just can't figure out why.
N_m3u8DL-RE works without any problems and dash-mpd-cli-windows.exe is in the same binaries folder as N_m3u8DL-RE.exe.

[Attachment 90934 - Click to enlarge]

[Attachment 90935 - Click to enlarge]
I just restarted my PC, but I'm still getting the same error

[Obo]

Looks at least correct from what I can tell.

As a MacOS user, I'm afraid I'm out of ideas here.

[Kimble89]

Since N_m3u8DL-RE works, that's basically fine. The only thing that bothers me is that I always have to manually add “--check-segments-count false” to the command, otherwise it “aborts” the download.
And if I simply add “--check-segments-count false” at the end in the GUI, this part is ignored. So I have to copy the entire command from the GUI every time and paste it into PowerShell, then change the name, etc. That's a bit annoying It would be great if the GUI had a switch for “--check-segments-count false”

Maybe that would be something for the next version @A_n_g_e_l_a

[Obo]

Can't you simply change the line where the command is built in gui.py? In my version it's line 411:

self.n_m3u8dl_re_command = f"N_m3u8DL-RE '{mpd_url}' {key_str} --save-name {self.video_name_entry.text()} -mt -M:format=mkv:muxer=mkvmerge"

[Kimble89]

You are a Legend Thank you that worked

[A_n_g_e_l_a]

...that worked

And the reason that YOU need it is because some packagers omit the final segment if it is only partially full. N_m3u8DL-RE calculates, say, seventeen segments (in the example below), but the CDN's packager has only delivered 16.

It works something like this using information in the MPD

mediaPresentationDuration = PT1M36.720S → 96.720 s total
Video SegmentTemplate: timescale (frames/sec) =25, duration=150 frames → 150/25 = 6.000 s per segment
96.720 / 6.000 = 16.12 → ceil = 17 segments Or 16.12 → floor = 16 segments.

As a coder I cannot know how the packager voted (ceil or floor) and must leave you with the tool to adapt to your specific use.

If I hard code 'check-segment-count false' there will be occasion, on slow or poor networks, when the downloader stops before all segments are captured. And you wouldn't like that either.

[Kimble89]

Thank you for the explanation.
I understand.
I didn't say you should hard code. I said a switch or a checkbox would be great.
But for me its working now. Thank you again for this script

[A_n_g_e_l_a]

a switch or a checkbox would be great.

In the event N_m3u8DL-RE fails just use DASH-MPD-CLI; that is what it is there for!

[Kimble89]

Yes, I tried that. However, I then received the error message shown above. That's why I asked for help here regarding the error message.

[A_n_g_e_l_a]

Yes, I tried that. However, I then received the error message shown above. That's why I asked for help here regarding the error message.

I was going to leave you for a couple of days to read and think about the error message you posted. It tells you what is wrong pretty much. It cannot find the binary dash-mpd-cli. Others jumped in with a 'fix' - not a solution.

It is obvious to me, you chose not to use the install script available to you. The script is pretty much idiot-proof.
But, nevertheless, I still get called and told I need to fix things in my script so as to sort out your mess!

Your dash-mpd.cli was not installed correctly - you've got it named as dash-mpd-cli-windows.exe.

[SnoopDawg]

@A_n_g_e_l_a thanks for this! I tried looking at a solution for downloading videos for (UK) Channel 4 and Channel 5 a few years ago and gave up.

I thought I'd give it another go as I've been playing around with an AI client, Cline AI, on Visual Studio code. After downloading from GitHub all I had to do was "Open Folder..." in visual studio and ask Cline to download the video I wanted. It provided prompts / instructions on how to the the MPD and cURL licence and installed all the necessary software such as Python uv etc. Worked successfully for both programs on C4 and My5.

Given time I probably could have worked through the instructions and figured it out myself but this saved a lot of time and didn't require any thinking.
