Stanford AI Class: Week -1 (Consolidated video of all topics for week-1)

[Pseudo]

The videos on youtube are small topic-wise parts, which have been
stitched using ffm­peg by me into a consolidated single file, so peo­
ple can down­load and and sit watch them at peace here.

Would be very nice to see if this works on the iPad. I've noticed lots of "complaints", but it was stated that it will not be supported this semester. I wonder if they've thought about just putting it on iTunes U. Really nice that is. 

[Morgaine]

I tried to do the same thing with ffmpeg, but its rather eclectic commandline foxed me.  For example, concatenating two files using "-i f1.mp4 -i f2.mp4" would generate a file of approximately the right combined size, but when played in mplayer it would exit at the end of the first half.  Apparently the two sets of video time codes aren't being adjusted to be consecutive.

I did find another way of concatenating the videos though, using "mencoder" from the mplayer package.  My commandline is "mencoder -ovc copy -oac faac  part*.mp4  -o combined.mp4".  This operates on the 720p mp4 files captured from Youtube.

I'd appreciate it if you'd tell us your successful ffmpeg commandline. :-)

There are no seeds for the torrent. I did manage to get a a small portion, but all disappeared. If you have this file, can you please share it over torrent for the rest of us?

@StanfordAIClass several people created a Google Doc for Unit 1 notes: http://t.co/GlZb8DHb

[-µ-]

I was about to post/share this one (the Google Doc for Unit 1 notes), good thing someone else already did! Or perhaps synced?

[Pseudo]

1. Convert all videos downloaded from youtube using keepvid.com, from mp4 to mpg format:
     ffmpeg -i intro.mp4 -sameq 1.mpg

2. Concatenate all videos together one after the other
     cat 1.mpg 2.mpg 3.mpg 4.mpg 5.mpg 6.mpg 7.mpg 8.mpg 9.mpg 10.mpg 11.mpg 12.mpg 13.mpg 14.mpg 15.mpg > 1week.mpg

3. Reconvert from mpg tp mp4 format:
    ffmpeg -i 1week.mpg -sameq 1week.mp4                       (takes long time and eats up > 4GB of RAM while doing this)

Done!

Thanks for caring to ask! :)

[Pseudo]

I will seed between 9 pm to 8 am IST (GMT+0530 hrs)

[wale2wale]

Thanks a bunch.

I think you misunderstood the request. I believe Pupi was asking to share a non-torrent source to fetch the files from. I'd repost the file to http://ge.tt/ or http://www.largedocument.com, but can't get to torrents from behind this proxy either.

Is there a way to download the Homework 1 videos?

[Davy Meers]

Hi, 

maybe not the most convenient but it works:

1) find the Homework vieo urls on youtube, for example, http://www.youtube.com/watch?feature=player_embedded&v=CxjV8H50xfU

2) Use KeepVid to download the youtube video

Hi,

I know another way to save videos by net. Put that on the url bar from Windows Explorer "C:\Users\<<USER>>\AppData\Local\Mozilla\Firefox\Profiles\"
Replace the <<USER>> for the user name of your computer. Then navigate to the folder "Cache" which contains within a folder with a strange name. And look for the file that will be changing Kbits each time ,i.e. the file being downloaded at the moment. To facilitate, organize files by "Date Modified". That's it. :)

If you think that is too complicated, try KeepVid, KeepHD or Javimoya.

See ya!

Hi , if anyone has fast internet, would you upload the files from youtube to megaupload.com(or  similar sites)  in a zip or rar file?

[Paresh Mathur]

isn't using dropbox public folder good for this? Or are there any bandwidth issue.

[Davy Meers]

The videos for homework 1 are available in mp4 format at http://www.megaupload.com/?d=KSWL6D4Y (+/- 60MB)

Lower-quality version can be downloaded from http://www.megaupload.com/?d=EVS4WNK1 (+/-16MB)

For those interested:

i created a playlist on youtube and then used http://www.dvdvideosoft.com/products/dvd/Free-YouTube-Download.htm to download the entire playlist.

Regards,

Davy

I've spun up a couple of 100mbps seedboxes.

I've yet to acquire a 100% copy; I guess there's too much stress on the sole seeder from Pune, India.

Dropbox 'Public' should be fine for non-copyrighted content. (Are the lectures and homework copyrighted?)

Mediafire even supports pause and Resume for HTTP downloads, IIRC.

Someone please upload videos on Mediafire or 4shared. Since there's a few seeders uploading them on these sites provides us a permanent link to download any unit part anytime (not all units together).

[Justin Cook]

Excellent work! I wonder how much effort to get these videos on iTunes U? Seems like the perfect place for it.

[Stan Schwertly]

I've got a mirror of units 1 & 2 up at http://stantheman.biz/ai. It'll
be up as long as I have bandwidth to serve it, which is looking good
right now!

Perfect! Downloading everything :)

Thank you.

[prakash Neupane]

nice one!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

 

 

keep it up

[Vimal George]

Much appreciated Stan. I guess you have lots of bandwidth/unmetered.

User Pseudo has compiled the videos into a single file (i used that for Unit 2 instead of individual youtube rips)

http://www.sgcanand.com/2011/10/10/stanford-ai_class_consolidated_videos/

To all:

Few people without access to bittorrent are finding it hard to download those large files .

I guess they would appreciate it if you could carry it too. (or even serve it out of a Dropbox public folder for the cost of one-time upload bandwidth)

-Cheers from Indian Rural guy stuck on CDMA downlink.

[Adam White]

Thanks! i'll make sure to grab those later :)

I’d request some­one from among the tor­rent leech­ers (who’ve down­loaded the com­plete thing) to take this up! So sorry…

1st vid has no seeders, 2nd giving me speed of 30KBps and 3rd also 30KBps.. :(
