Support: Mobile Web Interface V2 iOS Streaming

[jreichen]

Not on the HD300. It did fix streaming for those files in placeshifter though. I'm not sure why it affected one and not the other.

Sound wasn't a problem on any official SageTV playback platform, only on my plugin.

Consolidating all the commands into this post...

When using your streaming plugin though, SageTranscoder.exe and ffmpeg.exe don't show any command line options in Process Explorer. Hopefully you'll be able to compare the above to your streaming options, since I don't have a way of finding them (unless you can suggest something).

Thanks.

That is for a .vob file that I ripped from a DVD. I don't have any audio files setup for Air Video so I can't really help there.

Hope that helps you.

Here's a command I captured on my server. There are some differences. Some don't mean much, like the cropping values. Others might, I'd have to read up on them and experiment with them.

/opt/sagetv/server/ffmpeg -threads 4 -flags2 +fast -flags +loop -g 30 -keyint_min 1 -bf 0 -b_strategy 0 -flags2 -wpred-dct8x8 -cmp +chroma -deblockalpha 0 -deblockbeta 0 -refs 1 -coder 0 -me_range 16 -subq 5 -partitions +parti4x4+parti8x8+partp8x8 -trellis 0 -sc_threshold 40 -i_qfactor 0.71 -qcomp 0.6 -ss 0.0 -i /media/media/sagetv/recordingsx/LateNightWithJimmyFallon-11302312-0.mpg -s 640x360 -aspect 16:9 -y -f mpegts -async 1 -vcodec libx264 -level 30 -bufsize 512k -b 1200k -bt 1300k -qmax 48 -qmin 2 -r 29.97 -vol 1024 -acodec libfaac -ab 40k -ar 44100 -ac 2 -

Here's the ones I would start with. They're in my command but not AirVideo's:

-flags2 +fast
-async 1
-level 30

You can omit --conversion-id and --port-number. They are specific to AirVideo's ffmpeg build and don't impact the conversion.

If you want to help me out you can experiment with the different params and ffmpegs on one of your recordings and compare the results.

How can I set different params and ffmpegs with your plugin?

[jreichen]

Just run them from the command line, not the plugin. Replace the dash character at the end of the command with the output file name. Then play the resulting files in wmp, vlc, itunes, or whatever you prefer.

Hi jreichen,

I am running Centos Linux x86_64 on a quad core AMD 64 computer. I used to have this running on my old i386 server. When I moved over I can get everything going, but I cannot see the movies. It is stuck on "Loading movies" on my iPad and iPhone iOS 4.2.9 (I am using this with TiSageTV) over WiFi. I have attached my logs and I installed libfaac0. Thank you for any help.

Thank you,

Doug

Jetty is definitely choking on the stream, like it's not finding the video file under Linux or something:

Hi Fonceur,

Thanks for a great iOS app. Is it possible I am getting this issue because I am running the IBM JRE?

Thank you,

Doug

Maybe you'll need to figure out the ffmpeg command line that the iOS streaming plugin is trying to use and find your way from there. It's possible that ffmpeg didn't properly install because it's missing something in that IBM JRE...

If you have another PC/laptop, try using a placeshifter client on it and see if the streaming/playback works, that should be a good test for ffmpeg...

[dougbrose]

Hi Fonceur,

Yes, I can run the placeshifter on my mac. One of the reasons I switched to the IBM JRE is that I thought the quality of playback I was getting from ffmpeg was better. I am not sure where I am getting the IOException?

Thank you,

Doug

The log only has the generic exception coming from Jetty saying the pipe is broken. It looks like your logging level is only at INFO. Can you turn on Jetty's verbose logging and send those logs? The instructions for doing that are in the first post of this thread.

Hi Jason,

Ok I see. I enabled the wrong sagetv debug log. Thank you for looking at this.

Thank you,

Doug

Seems like the jetty web server under Linux is missing a lot of the functionality, the log is full of missing methods/fields for the org.mortbay stuff... No wonder it's not working...

- Description of the problem

Just installed this addon today and got it working great on my iPhone 4. I then tried to use it on my HP Touchpad. When I get to the screen where it shows the picture of the videos first frame (on the iPhone it has a 'Play' triangle over it) and touch the picture, the HP Touchpad opens a bar on the right side of the screen where it wants to download the live stream. Clicking on the HP Touchpad download button does nothing.

HP_Touchpad.zip attached with log files and a picture I took of the screen.

(Note: for some odd reason the times in the jetty log are off by 5 hours. I did this shortly after 3PM (15:00 hours). The SageTV log file shows the proper time, but the jetty log is at 8PM (20:00 hours).

- CPU

Intel Core i7 Q820, 8G system memory

- SageTV server operating system

Windows 7 64bit

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

WiFi N

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

HP Touchpad

- iOS Version

WebOS v3.0.2

For one thing, the iOS streaming plugin denies streaming for unrecognized user-agents (i.e. web browser or apps), so that's likely the issue on the Touchpad...

Second thing, I doubt that WebOS has native support for Apple's HTTP Live Streaming...

Try with the latest version of the iOS streaming plugin, the TouchPad is no longer blocked...

[bond00]

Sorry in advance if this is a stupid/obvious question...but why not convert the video to H.264 and use HTML5 so any compliant browser can watch the streaming video? I think most mobile browsers support HTML5 <video> tag and have codecs for H.264 as well. Again...sorry if the answer is obvious.

[wayner]

I have used a few of the tools (Mobile Web, TiSageTV, AirVideo) that allow you to stream Sage to mobile devices and I have found that H.264 files, at least the ones from my HD-PVR, never seem to stream as well as MPEG files. That may be because they are in HD but I don't know that this is the only problem.

[Fonceur]

The streaming plugin is already using H.264... As for HTML5, I would think that is something for the web server itself, not for the iOS streaming plugin...

As for the HD-PVR files, a lot of applications are having problems with those too.

[Fonceur]

So has anyone updated to 1.3 and noticed any differences, good or bad? I'm guessing I would have heard something if I had broken it...
