[200] Airplay server for C200 and A100

[popcornmix]

Here is a youtube link of the Airplay server running on Popcorn Hour C200.

This follows on from discussion here and the original work done by gek.

I've created a googlecode project here

Now can be installed with CSI. See here: http://www.networkedmediatank.com/showth...?tid=33465

It is now in the default repositories, so just select Airplay-nmt to install.

It should advertise a bonjour airplay service called NMT.
You should then be able to play a video in standard video player app on iPhone/iPhone/iPad (requires iOS 4.2.1) and select NMT from the airplay menu.

Consider this beta. It may or may not work.
This has been tested on a C200 and A110. I imagine it will work on a A200/A210, and A100.
It uses TheDavidBox API on C200 type devices, and /tmp/gaya_bc on A100 type devices. It may work on other NMTs if they support these interfaces.

Nice progress!

Can't wait to test it!

Well done !

Great work! Will give it a go later tonight or tomorrow. Have you tried streaming from iTunes directly?

[-Coco-]

I've just tried it. Streaming Videos and displaying photos from my iPod touch 2nd generation on my C-200 works very nice. Streaming from iTunes doesn't work unfortunately. According to the output, the server recognises the video (which is DRM free btw.), but apparently fails to play it. The screen goes black for a moment and then I see the menu again.

And can we stream music from the iPhone?

[-Coco-]

I didn't even try because of the notes in the README file:

Quote:Works:
Video playback (tried up to 720p). Pause/play. Seeking. Progress bar.
Photos. Note you need to press SOURCE on remote and select flash mode. Not sure how to put NMT in this mode myself.

Will not do:
Audio (AirTunes). Uses a completely different scheme that noone has reverse engineered.
DRM protected iTunes videos.

iTunes with DRM is in the "never" category.
iTunes without DRM is in the "not now" category.

iPhone returns a "501 Not Implemented" to http HEAD requests. NMT player tolerates this on a C200 (not on HDX and possibly A100) and continues with the GET request and plays the file.
iTunes returns a "400 Bad Request" to http HEAD requests. NMT player does not tolerate this on a C200 and refuses to play the file. Gek's proxy could help fix this.

Would be nice if C200 treated 400 and 501 responses the same way (would also be nice if iPhone and iTunes were consistent). However a workaround would be to have a proxy that sits in between and rewrites the HTTP responses. I believe Apache can be configured to do this, but I'm no expert. If anyone knows how to do this I'd be very interested.

Another request. I play photos with a request like:
http://<popcorn IP>:8008/playback?arg0=start_pod&arg1=My-Test-Photo&arg2=http://jquery.com/demo/thickbox-3/images/plant1.jpg&arg3=1&arg4=rot0&arg5=bghide

which doesn't display the photo immediately. You still need to press source button and switch to app mode.
The equivalent video playback command does not require this.

Anyone know how to switch to app mode programmatically? E.g. from a http request, as a shell command or from C code?

I made a basic CSI package of the rev3.

It starts, but I have not found a way to actually test it since I only have non-jailbroken iPhone 3G. Should it be visible from iTunes on my Mac somehow?

Anyway; please test, I'll repackage if needed.
Temporary location: http://www.cerveras.es/feed/Airplay-nmt.zip
(Download, open CSI; menu -> File -> Install from file)

Popcornmix, gek please incorporate it to the googlecode repo if you are happy with it.
The daemon.sh is quite crude and web interface could use a facelift, so the CSI package files should probably reside in trunk too ;-)

If anyone else wishes to maintains this package, remember to use the default /bin/tar cvf (...) on the NMT to create the CSI tar file.

Doesn't matter. My iPod touch isn't jailbroken as well and it still works. Just start the airplay server on the NMT, open a video on your iPhone and tap the symbol right of the forward button. Then select NMT and voilà - video plays on the NMT.

Yes. iTunes (latest version) on Mac should see the device. Play a video, and there should be an airplay icon which should have "NMT" as a target. It won't succeed in playing (yet).

I see a problem. The line:
/nmt/apps/server/mDNSrespd-mips -b -n NMT -t _airplay._tcp -x deviceid=FF:FF:FF:FF:FF:FF#features=0x7#model=AppleTV2,1 -p 6000 -b

needs to have \001 characters between the txt records (where I've inserted #). Your version has lost these. I inserted these into my script with a hex editor which I accept is a nasty hack. I'm sure there is a nicer linux shell way of inserting these codes.

Your version won't work with iTunes (iTunes cares about the txt records - iPhone does not).

I knew I was going to find it:

echo $((#001))

Didn't work for me:

sh-3.00# echo $((#001))
sh: #001: syntax error: operand expected (error token is "#001")

This seems to work:
echo Hello`echo -ne "\x1"`world

So I guess:
/nmt/apps/server/mDNSrespd-mips -b -n NMT -t _airplay._tcp -x deviceid=FF:FF:FF:FF:FF:FF`echo -ne "\x1"`features=0x7`echo -ne "\x1"`model=AppleTV2,1 -p 6000 -b

would also.

Thank's for spotting that. After trying numerous combinations like ctrl+@ etc. in nano and vi I gave up and used a hex editor too. After opening the daemon.sh in nano again I saw it just printed ^A ...
Hexdump shows there's a 01, so I updated the CSI package, please give it a try again!
