Support: Mobile Web Interface V2 iOS Streaming

Seems to be working again on iPhone/iPad on iOS5 for me. Just have the HDPVR file pauses I used to have during playback.

Thanks for getting this fixed.

Can anybody verify for me if the HP Touchpad works with streaming video? Is there anything that needs to be loaded on the HP Touchpad itself, to make this work?

I have access to the webinterface, and I have an option to "Watch Now" "On this Page", but the screenshot at the top seems to be fixed - there is no arrow on it for displaying video.

I've read the comments in this forum, and I believe that I have the 1.3 version of the Multimedia Streaming plugin (downloaded via SageTV Plugins).

Any ideas? Am I missing something simple, or should I start uploading logs?

From what I remember, reaching the actual playback was more convoluted than it should be, and I had to watch the demo video of the web server on geektonic to see how to do it... I don't know if it has changed since.

Would it be possible to use the 64 bit ffmpeg binary? That would be a faster at transcoding. It might only be 25-33% faster but it could get some folks over the hump without upgrading servers.

Actually, on Windows it uses SageTV's version...

- Description of the problem

I was traveling this week and went to use the web ui to watch some recorded shows. But once I got to the shows I found that none of them could be watched. Every show ends up with a circle with a line through it on top of the picture with the 'play' symbol. (see attached photo.jpg)

It has been working in the past. A few weeks ago I did go through the plugins and applied all updates. Which ones those were I don't recall. I updated 5 or 6 at least.

- CPU

Intel Core i7 Q820

- SageTV server operating system

SageTV V7.1.9.256 running on Win7 64 SP1 Pro

- Wireless Connection (WiFi G/N or 3G)

WiFi G, WiFi N or 3G (same results on all three of them)

- Type of device (iPhone, iPod touch, iPad)

iPhone 4

- iOS Version

5.0.1

First of all, the fact that you are seeing that "denied" circle probably means that it never reached the iOS streaming plugin itself, it's the mobile web server itself that would be producing it...

From a glance at the sagetv_0.txt, your jetty web server has some serious issues... The log is full of exception... Did you move the server to a different OS/PC or something?

[CptKirk]

No, no moves. It's been running on the same machine / same OS for months.

Absolutely love the iOS streaming plugin, but would like to increase the quality of the video streams. One thing I notice is that the streams look like they are 15FPS, and resolution looks like QVGA perhaps. Perfectly viewable, but I think my server can do better. I see that high motion scenes tend to saturate the encoder's rate.

The SageTV transcoder process is using about 15-18% utilization on my six core PhenomII CPU.

All of my video is R5000 captured TS and MPEG files from Dishnet, so the initial quality is there.

Can we make adjustments to the encoding quality (templates perhaps)?

All the best,

Benjamin

In principle it uses a playlist with variant bit rates, so if the bandwidth permits, it should end up with a much higher quality... If you want to force a specific bit rate, you would need to add the following to the streaming URL:

&Quality=440

where 440 can be replaced by a value among: {150, 240, 440, 640, 840, 1240, 1840}

The source code is at:

http://sageplugins.cvs.sourceforge.n...ediaStreaming/

If anyone figures some issues in there, I could push an update, but nothing has jumped out last time I checked...

Does anyone know if the transcoder is multi-threaded? If not, you'll never see more cpu utilization than what you're seeing now. 16% for a single threaded program on your six core cpu is actually 100% of a single core.

[Slugger]

The Sage transcoder is not multi-threaded.

[Fonceur]

Technically they are using a version of ffmpeg, and the streaming plugin is supposed to use the option to use multi core, but as Slugger said, it's possible that they disabled it in their compilation or something...

I think that the Linux version is using the regular ffmpeg, so it might be possible to modify the iOS streaming plugin to also use it and gain some performance...

I find the audio blown out when streaming. Is there any way to tweek this?

I am planning on setting the audio to 64k instead of 48k and some other little tweaks, so that might help...

EDIT: I do see that the volume is at 1024 instead of the default 256, so I'll try 512...

[Fonceur]

I've submitted version 1.3.3 which should be slightly better... I've increased the audio bit rate and dropped 2 video bit rates (to reduce the CPU load).

My plan is to drop even more bit rates, but instead have the streaming app provide its connection type (wifi/cellular) and device's width, so I can target it better... Of course if you are using the web server, that won't help you...

As far as I can tell, the pause at 10s is due to switching from the lower quality setting, which shouldn't be an issue if my plan works...

[Fonceur]

Version 1.3.4

- Try to use the original video's frame rate.
- Adjust bit rates based on initial quality.


Version 1.3.3

- Starting at higher initial bit rate.
- Disabled -bt.
- Reduced volume to 512.
- Increased audio bit rate to 64kbps.
- Removed the 640 kBps quality.


Version 1.3.2

- Removed the 1840 kBps quality.
- Reordered the qualities.


Version 1.3.1

- Disabled the authentication to enable Android streaming.

I am working on developing the SageTV addon for XBMC and am looking preliminarily at mobile streaming services. Assuming an iOS / HLS-compatible browser is available, what is the syntax for the URL that is used for streaming?

I see it might start with /stream, but am curious on what comes after? Do you pass in the mediafileid somehow?

I searched around and couldn't seem to find the answer in any of the documentation.

You want something like:

	    final StringBuilder sbURL = new StringBuilder("http://");
	    sbURL.append(hostname);
	    sbURL.append(":").append(jettyPort);
	    sbURL.append("/stream/HTTPLiveStreamingPlaylist?MediaFileId=");
	    sbURL.append(ID);

	    sbURL.append(ID);

Perfect, thanks. And is there a way for to spit out a result that is a .m3u8 file? I see the file it spits out if I open that link in a browser is HTTPLiveStreamingPlaylist but with no extension on it.
