I remember that this script used to always add the extra HQ-ness to old standard videos, but it doesn't seem to be doing it anymore.

http://www.youtube.com/watch?v=HVn5kQx8xL8 Check at 1:45 and on with the script, then check again by adding an fmt=18. The Use HD is indeed on.

Not all videos have a HQ version available. That seems to be the case in that video.

This video has a HQ version, but can only detected by loading the fmt=18 watch page.

I noticed that also. I would love to see that functionality back

I was annoyed enough by this too, so I fixed it.

So, replace lines 360-361 in 1.1.4:

if(unsafeWindow.isHDAvailable && !opts.useHD) swfArgs.fmt_map = unescape(swfArgs.fmt_map).replace(/^22[^,]+,/,"");
else if(swfArgs.fmt_map.indexOf("18")==0 && /3[45]/.test(swfArgs.fmt_map)) swfArgs.fmt_map=swfArgs.fmt_map.replace(/18.+?,/,"");

with this much longer block (I like spacing & comments):

/****************************************************************
// if not using HD or it's unavailable for this video, 
//  then get HQ (18 or 35) instead of whatever default fmt
//
// Each fmt_map entry is 5 fields separated by '/' starting with

//
// Note the following formats for reference (2009-10-16)
// fmt=0  -> flv:  320x240 (flv1) / mp3 1.0 22KHz (same as fmt=5)
// fmt=5  -> flv:  320x240 (flv1) / mp3 1.0 22KHz
// fmt=13 -> 3gp:  176x144 (mpg4) / ??? 2.0  8KHz

// fmt=22 -> mp4: 1280x720 (H264) / AAC 2.0 44KHz

The list of formats is from GIJoe's Youtube Enhancer script. Thanks for that!

So now you can listen to she in HQ. I kinda like their songs, have listened to a few in a row now.

cheers

So is this going to be included in the 1.5 update that just came out a few minutes ago?

Feel free to use the code as you see fit, Avindra. Don't worry, you're not stealing one bit. I put it here so that people can use it if they want. Afterall, you've done me a much bigger favor by publishing this script in the first place!

BTW, per 1.1.5 there's one change - rename unsafeWindow.isHDAvailable to config.CFG_IS_HD_AVAILABLE. Thanks for making that fix yesterday!

Hi
In case anyone's still looking at this topic: we're trying to force YouTube to give us video in the H.264 480x360 format (fmt=18) by changing the fmt_map parameter to just contain that option (fmt_map=18/640x360/9/0/115) but all it gives us back is format 5 (FLV/Sorenson). This seemed to be a recent change, it was working okay up until a month or so ago. Has anyone else seen that or got any hints as to how we force YouTube to serve up video in H.264 baseline profile (fmt 18) rather than main/high profiles (fmts 34/35)?
thanks
Andrew

Thanks for the response. We're not using your script I'm afraid - we're actually implementing a Flash Player so sadly we can't redirect the page for this. Though I suspect this will make it into a 'readme' for us somewhere!

We'll also look into more details at fmt_stream_map and the other FlashVars that are being passed in, thanks for this hint.

Do you have any more details on this second part of the fmt_map items?
(RegExp.$1=="0" ? "512000" : "640x360")
e.g. what's the difference, does this have any impact? I'm assuming the first usage is a bitrate and the second is the resolution, and I think I've seen both in different videos.

cheers
