Watch live TV from any computer or e.g. smartphone (Android)

[diego_dambra]

Using the video feature in Subsonic it's possible setup and stream a live TV channel



How it works: Allows you to select a TV channel and view it through Subsonics JW flash player (ffmpeg is the used to transcode the HDHomeRun video stream and play it).

Requirements: hdhomerun.pl script (to be placed in the Subsonic transcode folder), hdhomerun_config tool and Perl.

How to set it up:
- download the hdhomerun.pl script and copy it to your Subsonic transcode folder (/var/subsonic/transcode/)
- ensure the script has execute permission (chmod 755 hdhomerun.pl)
- add folder with HDHomeRun .strm files to Subsonic - Settings -> Music folders -> Add music folder (see below, if you need help with .strm files)
- add .strm extension to Subsonics Video mask - Settings -> General -> Video mask -> add .strm to the end of the listed extensions
- add new transcoding to Subsonic - Settings -> Transcoding:
Name: strm > flv, Convert from: strm, Convert to: flv, Step 1: hdhomerun.pl -s %s, Step 2: ffmpeg -ss %o -i - -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -v 0 -f flv - (and ensure Default and Enable are checked and then click the Save button)
- the new transcoding must then be enabled for the Players you've configured - Settings -> Players -> Select player -> Active transcoding: check strm > flv and then click Save (repeat for each player you plan to use)
- done

How to use:
- Navigate to your folder with .strm files and click play on any of the listed channel files - streaming will be shortly.

Advanced configuration:
- see hdhomerun.pl -h for advanced usage, e.g. set specific tuner or select first available. Add options to the Subsonic transcoding step.

Issues:
- video stutter - check CPU usage, transcoding requires a lot of CPU and if it hits 100% you'll probably experience bad quality. Try lower quality, e.g. 400kps through the JW flash player.
- MS Windows support, the script will need some tweaking to work. Post if of any interest.

How to create HDHomeRun .strm files with TV channel information:
- you can use the hdhomerun.pl script to create .strm files, see -h for usage (hdhomerun.pl -h)
- or, use the HDHomeRun tools to create .strm files

- MS Windows support, the script will need some tweaking to work. Post if of any interest.

I would be interested. I installed Perl on my Windows 7 system and tried everything you posted above but couldn't get any .strm files to play. Subsonic would just display a black Flash window with a long line of numbers across the middle. Subsonic could play normal videos, however.

[GJ51]

I'm a very big Subsonic fan and would love to get this up and running on my servers. I already have all the video bugs worked out and have enough horsepower to do the transcoding on the server.

All my Subsonic instances are on Windows platforms. I've never tried using perl scripts on Windows, so I'd need to know what to do to get everything up and running for the live streaming.

If we can get this worked out, I'd be happy to post the results and instructions on the SS board as well.

First of all...that is awesome. I've wanted to merge my HDHomeRun with Subsonic for some time. I have a linux server and everything just works per your instructions on my remote PC. (while writing this up, I figured out how to get it to work on my android. I kept writing to let others know what I had to do.) I am using Ubuntu 11.10 & Subsonic 4.6.beta1.

I've got a directory with my stream files in it...'Stream 11.strm' for instance streams channel 11. I can see these stream files within subsonic(PC) if I view the TV folder. They are not links like other content, but if I press the arrow to the left, they play. If I choose 'All Folders', the stream links are at the bottom. As a result of this directory structure, I was not able to play these on my Android. [Solution] I found that I needed one more layer of directory structure in order to see the stream files on my android. That is:
My 'Subsonic - Settings -> Media folders' has this entry: [TV] [/media/tv]
My directory structure should then be '/media/tv/Streaming/Stream 11.strm'
Now, on the PC, the Streaming folder has my streams...as well as on my android. If I do a search for 'Streaming', I have a search result with my streams in it.

I love this!!!

First/only Question: is there any way to default the kpbs to something other than 1000? My home DSL uplink speed is 896kbps and I have to set it to 300kpbs on my remote computer and android to play stutter free. This is a minor inconvenience to have to set the bitrate to 300kbps...but maybe someone knows how...

[hotshot2k3]

A working Windows version would be great.

[koch454]

I have used both the hdhomeruntools and hdhr-mkchan and have only got stream files for certain channels. The main channels I am looking for are ESPN HD and other sports channels. I haven't figured out how to use hdhomerun.pl -h. Also I can't seem to get it to work with android.

[kazman]

Hi,

Thanks this is great.

I have change the step 2 to ffmpeg -ss %o -i - -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 - which seems to get better quality.

I have the same issue with Android but I also have a problem that I can't stream any live tv for more than 3 minutes. Has anyone else seen this problem. I am using subsonic 4.6.

Cheers

Wanted to share an update on the hdhomerun.pl file that allows for program channel numbers that are float (use decimal) in your strm files. The default hdhomerun.pl file regex will only detect a digit. Anyways, here it is:

Edit hdhomerun.pl in any simple text editor such as GEdit on Linux:

Around Line #115 Find:

Code: Select all

    if ( $hd =~ /channel=([^\&]+)\&program=(\d+)/ ) {

Replace with:

Code: Select all

    if ( $hd =~ /channel=([^\&]+)\&program=([0-9\.]+)/ ) {

Save and close file. Copy updated file to /var/subsonic/transcode

---

Transcoding with the following:

Step 1:
hdhomerun.pl -t any -s %s

Step 2:
ffmpeg -ss %o -i - -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 -

BIG THANKS TO THE CREATOR OF HDHOMERUN.PL!!!

[ckergald]

Can anyone please re-post the hdhomerun.pl file, link appears to be dead.

thanks.

I have had no luck with this on HDHomeRun Prime.

Here is the source code, I found it on the subsonic forums:
http://forum.subsonic.org/forum/viewtop ... run#p50818

I have modified this to include the patch mentioned in this post, I've also modified some paths to windows paths c:/progra~1/Silicondust/HDHomeRun/hdhomerun_config.exe, please change according to your OS.

Under windows, I had no luck decoding the streams that were getting handed off to ffmpeg.

I used the latest ffmpeg builds from here with no luck:
http://ffmpeg.zeranoe.com/builds/

Here are the ffmpeg logs from subsonic.log:

http://pastebin.com/7eB0JTB6

I should also clarify that this is what I have in subsonic's settings->transcoding:
Step1:
perl c:\subsonic\transcode\hdhomerun.pl -t any -s %s
Step 2:
ffmpegnewest -ss %o -i - -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -f flv -vcodec libx264 -preset superfast -threads 0 -analyzeduration 100 -probesize 10000000 -

Also, after installing Activeperl, I had to copy perl.exe int c:\subsonic\transcoding

Even though perl.exe was part of the system path, it was not getting picked up, as there seems to be a hardocded path somewhere. Another solution would have been writing a .bat launcher piece in c:\subsonic\transcoding. I'll let someone else figure out the best thing to do under windows.

This new ffmpeg stream source option might be the way to go for this:

viewtopic.php?f=16&t=13625

As discussed in the documentation here:
http://ffmpeg.org/ffmpeg.html

‘-re (input)’

Read input at native frame rate. Mainly used to simulate a grab device. By default ffmpeg attempts to read the input(s) as fast as possible. This option will slow down the reading of the input(s) to the native frame rate of the input(s). It is useful for real-time output (e.g. live streaming). If your input(s) is coming from some other live streaming source (through HTTP or UDP for example) the server might already be in real-time, thus the option will likely not be required. On the other hand, this is meaningful if your input(s) is a file you are trying to push in real-time.
