Error Id: ou1cimx1#883906

Synopsis: Case 883906: Streaming WM HTTP content without media extension fa=
ils

Overview:

When the URI opened for streaming is WM content and if it does not have an =
extension associated with the URL, then following operation happens based o=
n the protocol name in the URI:

- mms:// - In this case asf_fileformat_net claims it (as its mms) and co=
re loads this dll and streaming happens as expected

- rtsp:// - rtspclnt takes over and tries to connect with the WMserver, b=
ut eventually lets asf_fileformat_net do the streaming

- http:// - http_filesystem is recognized as the preferred file system (a=
s the URI has http as the protocol and it does not have an extension). Core=
 loads httpfs and it fails after loading corresponding file format (asf_fil=
eformat_file) as it HXR_INVALID_FILE while reading the file header. HXFileS=
ource::InitDone receives this error and the same error is reported back to =
the controller and the playback ends with HXR_INVALID_FILE

But if we have an WM extension with the URI, we don't get into this situati=
on for http:// URL as it is directly handled by asf_fileformat_net, as it c=
laims the protocol-schema pair.

This CR addresses this use-case to make it work by trying with mms:// when =
http:// fails to stream the content.

Solution:

Changes in Core:


- HXFileSource::InitDone receives the error and Reports the error

- In HXPlayer::ReportError, if the error is HXR_INVALID_FILE, then we at=
temp a ProtocolSwitch based on the current URI (from http:// to mms://)

- If its possible to do so, then communicate the controller about possib=
le protocol switch so that controller can prepare itself for the same

- Reopen the new URI


Changes in (Symbian) Controller:

- While in Buffering state, if we get HXR_PROTOCOL_SWITCH_MESSAGE informa=
tion message from the core, then don't change the state to ERROR as we are =
expecting re-attempt by core with protocol switch

- While in Buffering state, change state to CLOSED after receiving OnStop=
, only if we are not waiting on protocol switch

- Communicate Playback/Prepare complete (OnPresentationClosed) to the app=
lication unless we are we are waiting on protocol switch

I have introduced a new helix error code (HXR_PROTOCOL_SWITCH_MESSAGE) for =
the same and a corresponding Symbian error code (KErrExpectingProtocolSwitc=
h)
