twitch.tv support only downloads first 30 minutes

[rmunn]

The twitch.tv support (#592) ends up only downloading the first 30 minutes of the video, because that's all that the twitch.tv server provides through that API. One video where you can see this in action is http://www.twitch.tv/avidyazen/b/352351813 -- note that the twitch.tv player shows a length of 5 hours, 34 minutes and 30 seconds, but downloading via youtube-dl currently downloads only the first 30 minutes of the video.

If you experiment with the twitch.tv player by pausing it and letting it download as much of the video as it can, you'll find that it downloads 30 minutes of the video and then stops downloading; if you then jump to the 29-minute mark, you'll see the video stutter a bit at the 30-minute mark, then resume as the player starts downloading the segment from about 0:30:00 to about 1:00:00.

I don't know how to find the URLs for the other segments of the video, but maybe someone else who sees this issue will have in idea of how to find them.

The video link I posted in the original issue report has been deleted, but by downloading http://www.twitch.tv/avidyazen/b/354807424 I can confirm that #621 does fix this issue. Each video segment downloaded will only be 30 minutes long, but with #621 applied youtube-dl will download all the segments of the video.

This was working fine some weeks ago. I tried downloading a video today and only got the first 30 min file. Seems like it broke again.

This issue is still present

I just upgraded to youtube-dl version 2014.04.13, but I am running into this same problem.
I am trying to download this Twitch.tv broacast, about 3 hours long -- http://www.twitch.tv/dabigbooi/c/4067025 -- but despite claims by Youtube-dl of contrary, it only downloads a 30-minute sample from somewhere in the middle. Log & proof below:

I can confirm it fails as well in version 2014.04.21.6

I have the same issue here also.

@phihag can you reopen this, please? I'm seeing the same issue as well.

As you can see in the chapter warning, the video is way over 30 minutes, but that's all that gets downloaded:

I'm seeing this issue as well, and here's the example I'm trying to download:
http://www.twitch.tv/fatbosstv/c/3851202

Hopefully this can be fixed before Twitch's changes...

[texke]

A a (temp) workaround you can use the '%(id)s' var in the filename (-o option), it won't try to overwrite anything but will make multiple files of the same stream.

In the latest versions it should work fine. For example for http://www.twitch.tv/pibonacci/c/4043233 it downloads the stream in 7 parts. If you still have problems, feel free to open a new issue. Thanks for the report!
