Now PHP support is broken??

[DanDon]

If have had Youtube-DL implemented on a website of mine for a while now, using PHP to back-end run the youtube-dl with a POST'd youtube link and then embed the resulting downloaded MP4 inside an HTML5 video tag. To bypass youtube filtering among other things. The problem I have is that the most recent youtube-dl.exe, possibly due to Youtube changing the way their videos work, no longer uses one command line process to finish. Therefore PHP assumes the command has completed before the video has downloaded and quits out of the command.
This only happens for links that have encrypted videos (like Vevo). All other normal videos work fine. I presume this is due to Youtube-dl being able to capture these in one command.
Any ideas or possibility of a fix?? Thanks in advance

Could you post some log or at least the command you are using?
I've never seen something similar to what you are saying, the videos are downloaded with a single invocation to youtube-dl. Of course if there's some problem during the download (like network errors) it will exit without finishing the download, but that's normal.

In the PHP head I am assigning a variable to
youtube-dl.exe --get-id LINK
Then I am running exec() to the Windows command line of
youtube-dl.exe --id LINK
and then having the HTML5 video embed the --id with an mp4 extension to play the downloaded video. Worked beautifully before but now the PHP finishes the command early and tries to embed a video that isn't there yet!

When outputting the PHP command to a txt file it shows that it stops on "Downloading JS Player":

[youtube] Setting language
[youtube] 0KSOMA3QBU0: Downloading webpage
[youtube] 0KSOMA3QBU0: Downloading video info webpage
[youtube] 0KSOMA3QBU0: Extracting video information
[youtube] 0KSOMA3QBU0: Encrypted signatures detected.
[youtube] 0KSOMA3QBU0: Downloading js player vfl1LZyZ5

Could you post what you get if you add to the command the --verbose option?

[DanDon]

The above at the end of my comment is the verbose output of what I get before it stops

[jaimeMF]

There's some missing output, it should start with:

[debug] System config: []
[debug] User config: []
[debug] Command-line args: ['0KSOMA3QBU0']
[debug] youtube-dl version 2013.09.12

(you may need to also capture the standard error output, I don't know how to do that in php)
By the way, can you reproduce it outside a PHP program (i.e. in the command prompt)?

[DanDon]

Ah the output to txt file doesn't give the full verbose info.. this is copied out of the terminal:

[debug] System config: []
[debug] User config: []
[debug] Command-line args: ['--id', '-v', 'http://www.youtube.com/watch?v=txBfhpm1jI0']
[debug] Encodings: locale 'cp1252', fs 'mbcs', out None, pref: 'cp1252'
[debug] youtube-dl version 2014.02.28
[debug] Python version 2.7.5 - Windows-8-6.2.9200
[debug] Proxy map: {}

Stops here

I get the correct result if I run the same command directly in the command line by the way. So it all works fine on the machine but not when using PHP. PHP can run commands in the terminal from a webpage fine as long as the command doesn't go off somewhere else or not send back info to say it's still going.
The annoying thing is that this did work perfectly fine :( I've only updated Youtube-dl and the server and PHP are the same as they have been. Can't remember now what version of youtube-dl worked, otherwise I'd try it; I'm guessing it's been updated though because the old one doesn't work with YouTube anymore, so probably wouldn't help :'(

If it helps you understand it:

and use the youtube proxy search.

Seems like a PHP question more than youtube-dl. I think you just need to select a different way of running the command in PHP. The link below might help.
