Tvheadend

All SD channels I have tried get the error above, HD work but no sound, which I assume is the aac error.

Any thoughts?

@Guido - does my log look like it trying to run the transcoding but then...

webui: Stop streaming /stream/channelid/237?transcode=1&mux=matroska&acodec=AAC&vcodec=H264&scodec=NONE&resolution=384&bandwidth=0&language=, muxer reported errors

Any ideas?

Hi Neil,

Did you test using the android client or using the webinterface?

If you only tried the androidclient you first might want to try using the browser with an URL like the following:
( so without the bandwidth parameter) to see if it works:

http://192.168.0.30:9981/stream/channelid/4?mux=matroska&acodec=MPEG2AUDIO&vcodec=H264&scodec=NONE&transcode=1&resolution=384

Hi Alex.

I was using this - http://IP:9981/tv.html

As above - the SD channels errors out, and the HD channels don't have sound.

Thanks.
Neil

Ok, I did not know this would automatically use transcoding.

Did you try a URL like the one below?
(i .e. :
http://192.168.0.30:9981/stream/channelid/4?mux=matroska&acodec=MPEG2AUDIO&vcodec=H264&scodec=NONE&transcode=1&resolution=384

)
You can then easily try different codecs ( and I do not know if this is possible using the tv.html address)

Seems to work when using the VLC client, just not the tv.html client.

Cheers,
Neil

Ok, wel , that is something. It means transcoding works, and you should be able to change resolution etc.

I also cant seem to be able to use the tv.html client ( didnt know it existed actually).

i can say with ubuntu 12, it works out of the box. just with the packages https://github.com/john-tornblom/tvheadend.

first:
make a backup from your .tvheadend config dir. (copy)

if u install from some repo, u maybe dont have the testing version with transcoding support.

second:

else git clone to another folder. like
[...]

change in src/plumbing/transcode.c -> enable_transcode to 1 and
[...]

run tvheadend with your config backup
run
[...]
to your backup path

u can try it with http://IP:9961/tv.html

Hi, done all the above. - thanks so far.

However I understand what I've done. I've changed the file done /.configure and make with /root/tvheadend_transcode. the config is in root/tvheadend_transcode/backup/tvheadend with the various directories - accesscontrol autorec capmt channels channeltags config cwc dvbadapters dvbmuxes dvbsatconf dvbtransports dvr epgdb.v2 epggrab imagecache superuser timeshift tvhtime

How do I run tvheadend to use this version /root/tvheadend_transcode and my config?

Also the other tvheadedend is still running as I can still can access http://192.168.10.38:9981/extjs.html and has all my config in.

Sorry if all sounds basic and is probably my linux knowledge lacking rather than tvheadend - any help would be greatly received.

Hi Geoff,

This all depends a bit on your system (what linux version are you using?) and the way you installed the original tvheadend version ( using some package manager like apt, or from source?), but usually there should be a file called tvheadend in /etc/init.d:

You can stop this version by running

/etc/init.d/tvheadend stop

(and restart using
/etc/init.d/tvheadend start
later)

Now, you can run the binary file in /root/tvheadend_transcode as the user that usually runs tvheadend. In that way you will use your regular settings etc.

However, it is not advisable to run tvheadend as root;
Your regular tvheadend version will also probably not run as root, but as some other user, for example a user called 'tvheadend'(, but again, this depends on your system.). Use the same user to run your new tvheadend version.

Alex.

thanks - /home/geoff/tvheadend_transcode/build.linux/tvheadend. (transcoding version) How do I get it to look at my config files from original version? - I think my original config files with all channels are in /home/hts/.hts/tvheadend$ (i think)

Thank you again for helping with this.

I guess usually TVheadend is run as a user 'hts'.

So by now running as user 'hts' the same configfile and .hts directory will be used.

NB: Also, you can copy the initfile in /etc/init.d do 'tvheadendtranscode' , and then edit the file to point to the new version of tvheadend.
You can then stop '/etc/init.d/tvheadend', and start '/etc/init.d/tvheadendtranscode'
(using

/etc/init.d/tvheadend stop
/etc/init.d/tvheadendtranscode start

)

Hi Alex, many thanks for your help I feel I'm getting somewhere and understand the program. Everything works ok thanks however when access a channel with DD5.1 it comes up with

Sep 01 22:27:47.556 [ ERROR] libav: Unable to set encoding parameters
Sep 01 22:27:47.556 [ ERROR] transcode: Unable to open libvo_aacenc encoder

any suggestions on this?

apart from the above question... I have to say the transcoding is working perfectly, using the latest TVHclient app. trancoding automatically on the iphone and ipad is brilliant. thanks guys for all your help.

Hi Guys

I have compiled from source and enabled transcoding in the web interface, but when I try play it in VLC I get the following :

And the stream never starts. If I use that same URL in the browser it starts to download the file but shows no errors till I cancel the download.

Any ideas what I am doing wrong?

I found out the problem.

For some reason my VLC on Ubuntu 13.04 will NOT play the stream. Any other VLC I try plays the stream just fine!

having some truoble with the transcoding.

it transcodes the videostream fine to h264 , but i just won't transcode too aac. getting this output.

that is when using tvhguide on android.

i have tried libfdk_aac with ffmpeg and it works fine. it is just that tvheadend fails to find it it seems.
is it possible to recstrict tvheadend from using aac so that is uses something else like vorbis .
is it just me having this issue ? or is anyone elses the same problem and solved it.

thanks for your replys

I have the same issues! I build ffmpeg my self with libfdk_aac. If i use a .WAV to transcode it to AAC it's working nice. But i get this error in tvheadend:
