Transcoding Codec Error Rpi

Manuel 3

Hi,

I've just setup tvh 4.2.4-dmo1~bpo9+1~rpt1 on raspbian stretch,

I can setup streaming but I get the following error when I use the Hardware-accelerated transcoding:

I've already got streaming working on another pi running LibreElec and the TVH Service Plugin,

but unfortunately my headless setup keeps bugging.

Thanks for any help!

Hardware transcoding isn't available for the Pi yet AFAIA. :( Although I've seen "Unable to parse option value "high"" before, please open an issue for it. :)

As I've said:

I have transcoding running flawlessly on a RPI 3 with LibreElec and a TVH Plugin from here: https://www.kodinerds.net/index.php/Thread/58252-LibreELEC-Tvheadend-mit-GPU-Transcoding/

But I'd like to have it running on bare raspbian...

Thanks for the link, I'll look into this and get back to you, please bump this thread if I don't reply in a few days!

Thank you!

Here some more Info about the working TvH with Transcoding on LE:

I can also give you remote Access to this Rpi LibreElec via VNC and access to TVH if needed.

mpmc

Could you give me the build lines in About? it's under "toggle details".

Thanks.

Manuel 3

Sure.

I've sent an e-mail to CvH to ask for info on how Libreelec is able to do this so I can look into getting it on Raspbian, I hope I have the right address!

CvH

You need at least the 4.3 builds from http://build.mycvh.de/ .

Unfortunately I had no idea that RPi transcoding works for Tvh at LE :D .

It was build with linking against a ffmpeg binary instead using tvh build in one (a holy mess with cross compiling). I only knew that the ffmpeg binary itself was supporting the rpi transcoding.

just have a look at the options used (there are x86_64/generic and rpi options)

https://github.com/LibreELEC/LibreELEC.tv/blob/master/packages/addons/addon-depends/ffmpegx/package.mk#L41

for Tvh I use this options

https://github.com/CvH/LibreELEC.tv/blob/9.0/tvh-4.3/packages/addons/service/tvheadend42/package.mk#L21-L82

maybe some setting is missing somewhere for you ?

Manuel 3

Thanks for your help guys!!

I'm currently trying to compile tvh with the presented options,

will report my status back ;)

btw: I have a pi transcoding DVBS Content since 2015: https://tvheadend.org/d/2859-stream-from-one-raspberry-pi-to-another?r=16778#message-16778 So it should be quite clear that the RPI3 is more than capable to do this :D

CvH

I know that it is working with ffmpeg but I thought it is borked with Tvh for the RPi.

Manuel 3

Thanks for your help,

compiling with the options from @CvH worked and transcodes fine!

Interestingly it does work, but only with 4.2 O.o. Anyway, I've updated #4572!

CvH

I have also a lot reports that HW transcoding is broken for 4.3 at LE with recent (1-2months) changes (x86_64).

Not sure that this is the actually problem but maybe (no time yet to search the problem)

Unfortunately I still have hiccups every few seconds on the raspbian build...
I'm using 4.2.7-34~g036b9cbab now but I cannot see where they come from, tvh doesn't log any errors.
gpu_mem is set to 256
Is there something tuned differently in libreelec?

CvH

we have an highly optimised build for RPi, but that shouldn't be the problem

maybe too old drivers/versions ?

Manuel 3

I'm using a Sat>Ip receiver as a box so there shouldn't be any driver issues?

Only difference I see is the ffmpeg version, but LE reports something about version 8.?

Anyways I blame it on a propably fauly Power Supply, but it is remote, I get back there in a few days :)

CvH

depending, LE9 ships soon with ffmpeg 4.1, currently 4.0 for Tvh

Martin Walter

I think this is a duplicate of #5308 and already fixed by @perexg in recent 4.2.7 and master branches. Maybe just build and try again...

Manuel 3

I still have hiccups on transcoded streams on a fresh raspbian and following the instructions from #4572
There is no error output and it seems as if the Pi cannot keep up with transcoding, CPU is at ~50% with a single DVB SD stream.

I also switched power supply, but still...

It's working fine on LE though :/
