Support: Mobile Web Interface V2 iOS Streaming

- When logged in to my network via VPN, the mobile interface works fine (over 8080, jetty non-ssl) - but the streaming will not work. I get the video play button in the crossed-out circle icon on iPhone (4.01) and a blank black box on the iPad (4.2.1). I understand it will not worked directly over SSL, but would have thought that VPN might have worked...

I would think it would work as well. Can you look in the jetty/logs folder for the log file that would correspond to the time you captured the log file you posted (I'm going to add this step to the first post)? There's a new log for each day. You might want to search/replace for anything you don't want posted such as server name. I'm wondering what requests are happening during this time.

I noticed something similar today. I was able to try it on Mac Safari and saw an HTTP 503 coming from the Media Streaming webapp (the url begins with /stream). I had to shut down Sage, delete the subdirectories under jetty/webapps (in my case it was the MediaStreaming one), then restart Sage.

Specs:
CPU Core Duo 2.2ghz
SageTV OS: Win XP SP3 32 bit
Connect iPad/iPhone to server via Wifi G
Devices:
- iPhone 3GS, jailbroken. 4.01
- iPad 4.2.1

It looks like your hardware should handle it.

Version 1.1 will be available soon. There are several fixes in this release:

• Increase volume on HTTP Live Streaming videos.
• Create a default web page to explain that this plugin is not used directly by the user.
• Use SageTV's ffmpeg for transcoding. The web streaming should now support the same files as the Sage core. Some users had reported problems with playing or seeking through avi, mkv, mpeg2, and wmv files.
• Fixed problems watching shows currently being recorded.
  • Playback duration was the length of the recording when playback began
  • Playback would fail if started immediately after recording started
• Added a URL to allow clients to kill transcoding processes on the server. The Mobile Web Interface does not use this API.
• Added more logging detail

Updated the plugin today, video wont even start to play on Iphone 3gs. Worked fine before. Tried uninstalling and re-installing, no change. It gets to "watch now" "on this page" but is unresponsive from there on.

Description of the problem - see above
CPU - Intel core2duo 3Ghz
SageTV server operating system - Windows 7 pro 64
Wireless Connection (WiFi G/N or 3G) - Wifi G
Type of device (iPhone, iPod touch, iPad) - Iphone 3gs
iOS Version - 4.2.1

Also broke the basic mpeg streaming on my iPod second generation...

[jreichen]

Thanks for the info. I'm looking into it.

[jreichen]

I have a fix ready but the plugin submission system is rejecting my update. It will be available once Sage support can help me resolve the issue.

Sorry for the inconvenience,
Jason

Version 1.1.1 is now available in the plugin manager.

OK, now it's working again. I can now stream avi files that I could not before.

Increase volume on HTTP Live Streaming videos.

Now the Sage TV recordings (Hauppauge PVR-500) and some other videos sound like thin can... The avi sounds good though.

[johnb263]

Works again here as well. Thanks for the quick response and thanks for a great plugin!

How would I go about using this URL feature? Reason being, I am having the following issues w/ v1.1.1.42:

-Upon restarting SageTV server (v7.0.23), I am able to watch 2-4 minutes of streaming MPEG4 recorded TV no problem. I am also even able to watch live TV.
-After 2-4 minutes, the streaming just freezes, and no matter how many times I refresh the mobile website and try to re-play the recorded TV, it opens the iOS player but nothing plays back. The only way I can get this to work again is to restart the SageTV server

What can I do to further debug this and/or get your support in trying to figure out why this isn't fully working? Much appreciated.

I'm still getting no play button, and the Watch Now>On This Page appears to do absolutely nothing. Streaming was working just fine before either of the 2 updates from this weekend. Let me know if you need a log file from me. I made a point of restarting the sagetv service even though the updates didn't ask me too. I also made sure that javascript was turned on on my iphone safari and turned on the debugger there. There were no errors.

I have to take back what I said - after updating to the latest release I tested it (without rebooting) and it worked (both WiFi G and 3G). I then rebooted the server and the problem is back. No play button on the video preview, no action on "play on this page".

I know this sounds really strange (I had a hard time believing it myself) but after the 2 updates this weekend I found that when I have the Jetty server logging set to INFO, streaming doesn't work...when I have it set to DEBUG or VERBOSE, it works fine. I have switched back and forth a dozen time and it is completely reproducible for me..

By resetting jetty logging I can get it to work, although may be an unrelated issue but the playback seems to pause itself every 30 seconds or so.

Thank you for the quick fix.

MrsNethead commented on the louder sound coming from her iPad and the Sage Video recorded stream looks better (much better)

I have a tester that is getting the following error, any idea? We can get the thumbnail, so the file is there... Straight from the mobile web server, the error is: "There was a problem rendering the audio portion of the content for playback".

The URL is

http://<server>:<port>/stream/HTTPLiveStreamingSegment?ConversionId=3bef0701-c89d-401b-aa83-f7562a8975ab&Command=stop&MediaFileId=11184677

You can get the conversion id from the log file. I'd like to get that working with the web UI but there are a lot of paths the user might take (pause, done, restart within media player, restart from web page, refresh web page, etc) and I need to see how that corresponds to the JavaScript events.

Check and see how many SageTVTranscoder.exe (Sage's ffmpeg on Windows) and ffmpeg processes are running. It will help if you can get the full command line. I think Process Explorer will do that on Windows or maybe you have a better tool. I use the following on Linux

ps -ef | grep ffmpeg

There will be two processes for each video. One does the transcoding and another does the segmenting.

The instructions in the original post for submitting logs and your system config will always help you get my support

For anyone with this problem, could you please try rebooting your iPhone/iPad/iPod? There have been times where the streaming stops working and a reboot will fix it for me. (Shocking for an Apple device, I know)

If that doesn't work, check to see if there are any ffmpeg processes running on your server.

Good, I was going to ask you to do that

Hmmmm... I always run with DEBUG or VERBOSE. At least it gives me something else to try. Too bad I need the logging though
