Allow option to use webproxy

[fool1223]

I'm trying to play a stream like the following:
​http://example.com/proxy.php?u=http://realhost.com/session/xxx/index.m3u8

The resulting m3u8 file looks like this:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:4
#EXT-X-MEDIA-SEQUENCE:1438367455
#EXTINF:4.000,
1438367455.ts
#EXTINF:4.000,
1438367456.ts
#EXTINF:4.000,
1438367457.ts
#EXTINF:4.000,
1438367458.ts

The problem is that ffmpeg doesn't stay on the complete url but instead downloads the file and than generates the new chunks like:
​http://realhost.com/session/xxx/1438367455.ts

Obviously this won't work. So I want to request a command line arg like '--webproxy' which would include the full original url like this:
​http://example.com/proxy.php?u=http://realhost.com/session/xxx/1438367455.ts

VLC can handle this type of urls already without problems but my software uses ffmpeg.

(I used the latest build ffmpeg version N-79173-gbe746ae for testing and also older versions)

Thanks in advance!

Please provide the command line that allows to reproduce the issue together with the complete, uncut console output to make this a valid ticket.

You can use any webproxy url (that ships out the untouched file) followed by a valid m3u8 file for example.
