i think people might be a little surprised when they're in ie or something and 50 new windows open. it's just a little treat for people in this thread.

Thanks Nate, that's certainly a nice surprise. I'll just copy those down into a text document or something for whenever I download 75 segments again. Smiley

EDIT: Err, wait, so it's not going to open 50 new windows for us too, is it?

nate

2011-04-27 11:16:00 am

depends on your browser settings. it should open 50 new tabs if correct. i believe in firefox those tabs automatically close when the download starts. in chrome, for me, they don't, which means a lot of closing empty tabs. you might just open a new chrome window with the download page and then close the whole window with all the tabs after all the downloads have started.

The whole "blank second page" issue I was talking about a couple of weeks ago still is an issue. I thought it was solved...

nate

2011-04-27 01:42:27 pm

no, all i did was stop unread view from ever automatically reloading. my guess is that issue will be solved by the new unread view - whenever i get around to that.

Hmm, tried that awesome javascript and my firefox just got a few billion tabs ^^ But it dosent matter, its easy to close and they dissapear after starting the download
Yes please add this as a feature Smiley

I agree with nate, probably best if it's just used privately rather than officially implementing. Not hard to bookmark this thread for future reference if you want to dl a segmented run.

Just curious what download managers people liked.

While Nate's tool is nice, I don't like the idea of all those tabs and I'd rather not have to copy and paste a script when I could just use a download manager that will download everything I select. I have DownThemAll for Firefox, but it makes me manually select each individual file I want to download (or deselect those I don't). If there was a DM that let me highlight a series of links from all of the ones available, that'd probably be ideal for me.

With downthemall you can highlight the links you want to download and then right click and select "dta selection."

Ah. I see I should have toyed around for more than a couple hours with DTA before posting. Okay, so how would I only select one column? (as in, I only choose the sda links or the archive links)

Here's what I do. Assume you want to download the normal quality of Star Fox Adventures from dl.

1) Go to the download page
2) Click Normal quality
3) Highlight all of the archive and dl links
4) Right click -> DownThemAll Selection
5) In the window that opens, click the Description column
6) Highlight all of the archive links that are now grouped together (use shift+click)
7) Right Click -> uncheck selection
8) Start download.

Seems like a lot but you can do it pretty quickly.

Yes, a cucco riding the ground.

As far as appending segments for personal viewing goes, I wrote a program that uses Mp4box to do it automatically. Unfortunately, with each appended segment, the audio goes further out of sync. Anyone know a way to avoid this? I was using this command:

Code:

mp4box -cat segment_1.mp4 -cat segment_2.mp4 ... -cat segment_n.mp4 -out output.mp4

Quote from Manocheese:

It happens because in a typical encoding, the audio and video tracks of an MP4 file aren't exactly the same length. So, if you concatenate a bunch of MP4s end-to-end, that minor difference in length cascades; by your fourth or fifth concatenated file, the audio and video are half a second out of sync.

I wrote a little program a while back that concatenates MP4 files in a way that keeps the audio and video in sync. However, the program only works on files with one audio track and one video track (so, for files with a separate audio commentary track, this program wouldn't work). If there were interest, I could try to adapt the utility to work with files that have multiple tracks.

I see. AviSynth handles aligned splices so easily that I forgot that problem even existed.

on a download page, paste one of these into your location bar/url box to queue all files for download:

You can also use a command-line approach, for anyone using OS X / *NIX:

Code:

i=1 ; while [ $i -le 32 ] ; do wget http://dl.speeddemosarchive.com/FinalFantasy2_305_mp4/FinalFantasy2_305_part`printf %02d $i`.mp4 ; i=`expr $i + 1` ; done

Quote from mike89:

How about the "it looks like a single-segment run but it's not" argument? Some runs on SDA are appended and they have run into this problem. I know it says it's segmented and appended to one file, but still.

I just wanted to voice agreement to this issue. I think that segmented runs should be clear about where they're segmented. But, I personally would like watching an appended file if it's clear where the segmentation points are (e.g., a shot of the title screen for the game, or some sort of placard that says "Start of Segment #5" shows up). I like just merging the files together (they usually include the title screen of the game) then watching the run on my TV, but it's easy enough to merge the files together after I've downloaded them Smiley

^ Yeah, like I said the multisegments looking like single segments isn't really even an actual problem (if you ever felt it was one - I personally didn't), because all you have to do is append the files without removing the statids. That's what I've been doing with my own personal encodes.

Poxnor, I would be interested in that program you suggested creating. If it represented a way to append any and all SDA runs into single videos, I'd love such a thing, assuming it didn't require as many manual appends as avidemux does.

That Guy

I would be very interested in that program as well.

It's going to sound absolutely crazy, but I tend to use speedruns to fall asleep - they block out all the rest of the noise of the apartment building in the middle of the afternoon, and the sound of videogames is just... really comforting to me! Unfortunately though, I can't do that with runs that are segmented into half-minute segments and stuff (Hell, I have difficulty watching them a lot of the time simply because I forget where I am!), so I'd love to have something like that.

Poxnor

Does anybody know of a segmented run with audio commentary, so that I have something with which to test the program?

Thanks!

Hold on. I'm gonna download the grappling hook segments and see what I can do.

-edit-

Turns out that they do get merged into one single file.
Its a different way of merging though.
Each video gets their own video/audio-track which you need to choose manually ^^
I'll go look for another solution then Tongue

-big edit-

Here is an alternative solution which doesnt require switching video/audio tracks :

1.) Go to http://avidemux.org/ and download avidemux.

2.) Open the first file. If you get a warning about b-frames say yes to using that mode.

3.) Go to File->append->open the second file

3) Set the video + audio sidebar to "copy" and the format to "mp4"

4) Go to File-> save video.

P.S.: Make sure to include an extension to your filename when you save it e.g. "bla.mp4".

P.P.S.: This is just temporary. I'm sure there's a more user-friendly way out there. I'll see what i can come up with.

I did a little test to verify whether there is audio desync and was surprised with the result.

1st mp4 file had 27 seconds of video, 15 seconds of audio.
2nd video had 27 seconds for both video audio.

Concatenate 1st and 2nd video...

Now usually what would happen, for example in mp4box, is that the first 15 seconds of audio would play immediately followed by the 27 seconds of audio = desync. In the case of AviDemux it actually kept it synced, however it filled that gap between the 15 and 27 second mark by looping the audio of the 1st mp4. I don't think that's a good thing, but certainly a different result than I expected. If someone can reproduce this to confirm my result, that would be appreciated.

edit- expanding on whether it's a good thing... I guess it depends. Imagine the mp4 starts off with a loud bang, and that loud bang getting looped... But if the gaps are very small, which they usually are, and you're not unlucky.. it may be a good method. Again, if someone can reproduce my result..

btw, regarding a solution to appending mp4's while keeping them synced. There should be a goal of not re-encoding anything, in order to save time and not lessen the quality due to going lossy to lossy.

No worries, my program doesn't re-encode. I just need to make the changes to it to support multiple audio tracks, then find a run to test it on.

My Wario Land 5 run fits this. I'm sure there's others but obv. that one came to mind first.

edit: not many segments, though... Skies of Arcadia Legends? Didn't that have AC?
