Transcoding so that TvHeadend streams IPTV

Bernard Mentink

Hi,

I understand that to get tvheadend to output an IPTV compatible stream then it must be built with the--enable-libav ./configure option.

However when I do that I get an error regarding -fPIC when building ffmpeg... as so ..

I have tried putting the -fPIC option in the toplevel Makefile in the CFLAGS and the Makefile for ffmpeg, but no difference, same error. DOes the linker and/or the assembler need this option as well?

(as you can see from the top line the -fPIC option is present when compiling C files .. )

Thanks,

It seems this might be an issue as well:

This is because you haven't passed --disable-bintray_cache but even if you don't it should still build fine.

I don't think you can use libav and ffmpeg together I believe it's one or the other, by default it builds static ffmpeg which should be able to output IPTV compatible streams.. Are you following some old tutorial?

Bernard Mentink

Never mind, I found out how to do it:

I had to edit Makefile.ffmpeg and add the config option --enable-pic in two places.

It then built fine complete with transcode support .... will try it when I get home.

Yes, I was following a howto in this thread: .. about 1/2 way in .. and yes, it is a couple of years old I see ..

https://forums.plex.tv/discussion/comment/544372

But the need for -fPIC is a bug I feel, maybe it is needed for Atom processor target?

Bernard Mentink

So I have this all working now, but I have no idea how I tell tvheadend to transcode my IPTV channels, so with the following URL:

#EXTINF:-1 tvg-id="5ead7218a1fb129f8391eea3da22a0cb",The Edge TV http://localhost:9981/stream/channelid/410168670?ticket=BCDABA77C54B2790F94C8166A38AE924384F2B9D&profile=pass

It looks like it is using the "pass" profile, do I simply tell it to use another profile?
Is transcoding documented somewhere? I can't find it ..

Bengt Madeberg

1) Set up a streaming profile in the "stream" tab.
2) Assign a new user in the "users" tab and set the streaming profile you just did.

3) Start the streaming with http://user:password@server:9981/.....

Done

Bernard Mentink

Thanks, but not quite getting it.

So in my example stream above do I do:
http://user:password@localhost:9981/stream/channelid/410168670?ticket=BCDABA77C54B2790F94C8166A38AE924384F2B9D&profile=pass

.. and change "pass" to whatever profile I have supported for that user?

Cheers,

If you set a stream profile for a user (in the Access Entries tab) it will use that by default (you won't need to define it in the URL if you pick just one (You will if you select two or more) ), if you don't set it tvheadend will use whatever stream profile is default in Config -> Stream -> Stream Profiles.

Thanks for that, tested and working.

I am feeding tvheadend iptv streams into Plex via a plugin and having issues with HD channels pausing/dropping frames, I thought transcoding might help, but it doesn't.

It seems I have some sort of buffereing issue between Tvheadend and Plex. Tvheadend streams 1080p fine to mpv player and Plex plays 1080p videos and 1080p streams on the net, just not tvheadends ..

At a loss on how to fix this, is there any buffer settings I can play with?
