Support for streaming from a ReplayTV

[rtvguy]

members of the xbmc team,

i have added a feature to xbmc requested by some that allows it to do streaming playback of shows recorded on a networked replaytv 4000/5000/5500 series. *i thought i would post here to get input on the best way to get this included in future versions of xbmc. *i assume that i should just add the necessary files and patches to the patch section on sf, but i wanted to go ahead and give a heads up here of what integrating this feature entails. *below is the readme file i am planning to include with the patches and source. *i appreciate any comments and assistance in getting this included and thanks for all your hard work on xbmc!

************************************************** *************************
xbmc support for streaming shows from a replaytv by rtvguy
************************************************** *************************
this patch adds support for streaming shows recorded on a networked
replaytv 4000, 4500, 5000, or 5500 series pvr directly to xbmc for
playback. *this is accomplished by adding a new streaming protocol to xbmc
that i call the rtv protocol. *this protocol is implemented in a manner
similar to xbms in that most of the code rests in a dynamically-loaded
library called librtv. *the source code to this library is included in the
patch .zip file.

integrating this patch into the xbmc cvs should be fairly straightforward,
as described below.

************************************************** *************************
changed xbmc files:
************************************************** *************************
1) xbmc/application.cpp
the included application.cpp.patch file modifies this file to provide
support for loading the librtv library.

2) xbmc/filesystem/factorydirectory.cpp
the included factorydirectory.cpp.patch file modifies this file to add
support for the crtvdirectory class.

3) xbmc/filesystem/filefactory.cpp
the included filefactory.cpp.patch file modifies this file to add support
for the cfilertv class.

4) mplayer/mplayer.dll
the file libmpdemux/open.c in docs/mplayer_sourcecodepatch.rar must be
modified to add support for the rtv protocol.
specifically, the following line:
if (stricmp(url->protocol, "xmbs") &&
stricmp(url->protocol, "xns") &&
stricmp(url->protocol, "shout") &&
stricmp(url->protocol, "cdda") &&
stricmp(url->protocol, "smb") &&
stricmp(url->protocol, "iso9660") )
must be changed to:
if (stricmp(url->protocol, "xmbs") &&
stricmp(url->protocol, "xns") &&
stricmp(url->protocol, "shout") &&
stricmp(url->protocol, "cdda") &&
stricmp(url->protocol, "smb") &&
stricmp(url->protocol, "rtv") &&
stricmp(url->protocol, "iso9660") )

5) xbmc.vcproj
the included xbmc.vcproj.patch file modifies this file to add the files
rtvdirectory.h, rtvdirectory.cpp, filertv.h, and filertv.cpp to the xbmc
project and also suppresses preloading of the librtv library.

************************************************** *************************
added xbmc files:
************************************************** *************************
1)xbmc/filesystem/rtvdirectory.h
the interface for the crtvdirectory class.

2)xbmc/filesystem/rtvdirectory.cpp
the implementation of the crtvdirectory class.

3)xbmc/filesystem/filertv.h
the interface for the cfilertv class.

4)xbmc/filesystem/filertv.cpp
the implementation of the cfilertv class.

5) docs/librtv.rar
this file contains complete source code for the librtv library.

************************************************** *************************
added xbmc directories:
************************************************** *************************
1) xbmc/lib/librtv
this directory should contain the librtv binaries built from the source
code included in "docs/librtv.rar" (release: librtv.lib, debug:
librtvd.lib). *this directory should also include the *.h header files from
the "docs/librtv.rar" file.

************************************************** *************************
instructions for use:
************************************************** *************************
setting up rtv shares in a build of xbmc that includes support for them is
easy. *just add the necessary info under the <video> section of
xboxmediacenter.xml, much as you would for a relax or xbms share *there are
2 different kinds of shares, each with two different show listing formats.

share type #1 - manual rtv share

listing format a (preferred)
the following example will display a list of recordings by name (as
retrieved from the replayguide) for the replaytv with the ip address of
192.168.1.100.
* *<bookmark>
* * *<name>name of your choice</name>
* * *<path>rtv://192.168.1.100/</path> * *
* *</bookmark>
*
listing format b
the following example will display a list of recordings by *filename only*
for the replaytv with the ip address of 192.168.1.100. *this can be useful
if for some reason your replayguide cannot be properly parsed (all known
replayguide formats as of 01/04 should be supported).
* *<bookmark>
* * *<name>name of your choice</name>
* * *<path>rtv://192.168.1.100/video</path> * *
* *</bookmark>

share type #2 - automatic rtv share

listing format a (preferred)
the following example will attempt to automatically discover and list in
xbmc *all* replaytvs on your lan. *selecting a particular replaytv in the
list will then display its recordings by name as described above.
* *<bookmark>
* * *<name>name of your choice</name>
* * *<path>rtv://*/</path> * *
* *</bookmark>

listing format b
the following example will attempt to automatically discover and list in
xbmc *all* replaytvs on your lan. *selecting a particular replaytv in the
list will then display its recordings by *filename only* as described
above.
* *<bookmark>
* * *<name>name of your choice</name>
* * *<path>rtv://*/video</path> * *
* *</bookmark>
* *
that's it!

i am not a dev and i don't have a replaytv, but this sounds veeery interesting.

[Gamester17]

cool, please submit the sourcecode on sourceforge (link here) and/or upload it here here (link) *

[rtvguy]

thanks! i submitted the sourcecode to the sourceforge patches section for xbmc (sorry about the screwed up formatting in the description there as a result of my copy/paste). let me know if any additional explanation etc. is needed.

[cyberplague]

awesome work! can't wait till this gets merged into cvs!

keep xbmc rolling!

cp

[cyberplague]

any idea when this will be merged into cvs? *i have a replaytv and would love to test it out!

let me know,

cp

[Eraserhead]

fantastic news! :d
i too would be happy to test it.

[tdfsu]

ditto. i will test it too.

[Frodo]

sounds cool.
however can you upload the files changed entirely
instead of patches?

no problem. *i uploaded an updated .zip file that includes the changed files at the sourceforge patch section for xbmc.
http://sourceforge.net/tracker....=581840

i noticed that changes have been made to the open.c file in mplayer_sourcecodepatch.rar since i last got it from cvs. *namely, part of the code that previously needed a slight modification to add rtv protocol support is now not compiled into the mplayer.dll binary due to mplayer_network not being defined. *so, currently no changes are needed there. *will that code be included again at some point in the future of xbmc? *just in case it will, i did include a modified open.c that includes the one-line change necessary for rtv protocol support.

please let me know if i can provide any other info that will assist in integrating this into cvs. *thanks!
