<tl;dr>Could the problem be that the plugin does not follow 302
redirects?</tl;dr>
I installed murkle's patched plugin yesterday - thank you for trying to
solve the problem! - but it still didn't work for me. So, in frustration
I had a quick look at the ProtocolHandler.pm module and switched on
debug logging for the plugin. I noticed that the plugin logged that the
stream ended, immediately after it had started to read it (or tried to
open it). So, I had a look at the network traffic using tcpdump and
wireshark.
The plugin makes a few requests, first downloading the youtube video
page, from which it parses out the relevant video urls. After some steps
it tries to start a video stream, which it will read the audio from on
the fly. What happened in the packet dumps that I got, was that it sent
an http request for the video stream, but got a 302 response from the
server, after which it just logged that the stream ended. I guess it
tried to read the video stream data from the 302 response (oops),
instead of actually following the redirect.
The ProtocolHandler.pm module uses the Slim::Networking::SimpleAsyncHTTP
module for fetching the urls. Looking at that module, it only has code
for 304 responses, which might explain it all. On the other hand, the
Slim::Networking::SimpleAsyncHTTP module does load the
Slim::Networking::Async::HTTP module, which has support for redirects.
I'm not a Perl person so I cannot see if it actually uses that code - I
assume it's not, since it doesn't follow the redirects :p
The redirects I noticed in my few test cases was that I got redirected
to a stream url which *only* differed from the original url by the
appending of the string "&ir=1&rr=12". From this I made the probably
moronic change
Code:
--------------------
#$url .="&signature=$props{signature}";
$url .="&signature=$props{signature}&ir=1&rr=12";
--------------------
to ProtocolHandler.pm, and now my plugin works again :p
I got to thinking, could this problem - not following redirects -
explain the problems with this plugin? Or I've misunderstood everything
:p
