RE: Transcoding Support TVHeadend - nhsman - 2015-06-10
Any idea what might cause continuity errors and how to fix it?
RE: Transcoding Support TVHeadend - negge - 2015-06-10
It usually boils down to bad signal quality or bad tuner.
RE: Transcoding Support TVHeadend - nhsman - 2015-06-13
I have checked and re-alined my dish. All transponders report between 80-95% signal quality. The issue still exist only on transcoded content.
I can play two different channels at the same time - one transcoded and the other one not. Only the transcoded content stutter but only after 15 minutes.
Please advise something as I am running out of ideas.
RE: Transcoding Support TVHeadend - nhsman - 2015-06-15
Anyone please?
RE: Transcoding Support TVHeadend - negge - 2015-06-15
Are you sure you're not getting the same continuity errors when not transcoding?
RE: Transcoding Support TVHeadend - nhsman - 2015-06-15
I have double check and here what it is:
I can play two HD channels without transcoding and I get no CC errors at all.
If I play two HD channels - one transcoded and the other one not - after some time I get hundreds of CC errors on both channels.
Any ideas please?
RE: Transcoding Support TVHeadend - nhsman - 2015-06-16
So I have installed fresh Ubuntu 14.04 x64, latest driver for my tuner, latest Tvheadend from master and the issue is still there.
Loads of CC errors when transcoding. I think that it's down to TVH as I tried on two different systems with two different PCI tuners (S952 and TBS6981).
Hope it will be fixed at some point. Till then I assume that transcoding is broken.
RE: Transcoding Support TVHeadend - Vlaves - 2015-09-02
I have also problems with stuttering while transcoding to an Amazon Fire TV. I use there Kodi as a Client and a assigned a transcoding profile to the User I'm connecting with.
The Profile is set to 720p with 8000 kbps. Then everything is fine even when trancoding a 1080i h.264 stream. But when I set the trancoding profile to 1080p and 10000 kbps it starts stuttering. The Server has an Intel Core i3-4350 CPU, which should be enough strong to handle that. Any Ideas where to look for an solution?
Thanks for your support here

RE: Transcoding Support TVHeadend - Vlaves - 2015-09-07
Hello,
maybe someone could at least point me to some direction to give more or better information, so you could better help out. I guess the stuttering is not coming from the Fire TV as I can stream a whole Blu-ray disk from my NAS with 35MB/s (Star Trek from 2009) without any issue. But from the other hand, I don't know if the PVR part from Kodi is using a different internal player maybe.
Please help me out to further investigate. Thanks a lot for your support here.
Best Regards

RE: Transcoding Support TVHeadend - gmp029 - 2015-09-17
Hello,
Does anyone know what the minimum system requirements are for transcoding mpeg-2 1080i live tv to h.264? I would like to build a new backend htpc running tvheadend, and have the ability to transcode live tv so that I can stream to my Amazon Fire TV box (the FTV doesn't play nicely with interlaced content). My current backend cpu usage is 100% when transcoding, and it can't keep up with a live stream.
Here is my current Backend:
Ubuntu 14.04.2 LTS
AMD Athlon 64 3200+ @ 2.2 ghz
1 gb ram
CPU usage is 100% when it is tasked with transcoding a live 1080i stream to h.264.
I would like to use a mini-itx htpc if possible, to keep size and power consumption (and cost) to a minimum. Any advice on specs?
How about something like this?

In general, what would be able to handle this?
RE: Transcoding Support TVHeadend - negge - 2015-09-19
I'd go for atleast an Intel i3, possibly even an i5 if you want to do two streams simultaneously.
RE: Transcoding Support TVHeadend - redstorm - 2016-08-11
you can transcode by setting the profile in the stream request.
i.e.
Code:
http://127.0.0.1:9981/stream/channel/8284f9421c7eb27ccb5051869ba25f78?profile=webtv-vp8-vorbis-webmThe above im tunneling out to home and this is an HD channel that i don't have the upload bandwidth to play the full stream so appending the profile to use in VLC i can get the stream at an acceptable bit rate that my broadband can handle.
