Difficulty to get MPEG-TS Spawn profile working

Pieter Hooftman

I'm trying to get Live TV channels transcoded to a lower bitrate to save bandwith. I know my Synology 918+ is capable of transcoding; transcoding in Jellyfin works flawlessly. But ticking the box 'hardware accelartion' in the WEBTV codec H264 doesn't reduce the CPU usage.

I created a MPEG-TS Spawn profile , pointing to a script file which contains

"ffmpeg -analyzeduration 1M -probesize 1M -i pipe:0 -bitrate 3000k -bufsize 3000k -c:v libx264 -preset superfast -c:a aac -c:s copy -f mpegts pipe:1"

I can tell the script is being called, but in the log i see that subscription to the live tv channel goes on and on, and TVHClient on my Android phone states 'cannot open file'.

A snippet of the logfile:

Any help appreciated

Variables location must not be in a bash script.

I put the contents of the script file directly into the 'Command line' box of the spwan profile, but i get the same error:

I am getting somewhere, this command appears to be invoking ffmpeg. Still no hardware decoding though but now i can start experimenting with hwaccel:

ffmpeg -i - -f mpegts -c:a copy -c:v libx264 -b:v 368k pipe:1

Flole

Well you didn't specify any option related to hardware decoding or encoding, so it won't be used.

Saen Acro

What hardware you want to use for hardware transcoding?

Pieter Hooftman

Yep, using

ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_device foo -i - -f mpegts -c:a copy -c:v libx264 -b:v 368k pipe:1

gives me this error, probably because the user running tvheadend does not have access to the renderD128 device..

Start to usePRE button when citate from terminal.

What is this Video card you want to use?

With your minimalistic information, it's hard to understand your problem.

Thank you very much! It seems that vaapi is not enabled in the versions of ffmpeg which is bundled with the tvheadend synology package.

So i'll hunt down a version which does.

The one who build it garantee it will not work on 1000% by set in build

--disable-vaapi

Use this one to build your ffmpeg static binary

Couldn't get the spawn profile working, i took the easy route and installed the linuxserver/tvheadend docker image which has a ffmpeg version bundled with VAAPI enabled. Works a treat.

Saen Acro

Do ffmpeg docker have access to device?


- /dev/dri/renderD128:/dev/dri/renderD128

Pieter Hooftman

Yes

Saen Acro

What is command line, used in spawn proffile?

Pieter Hooftman

i don't use the spawn profile anymore.

I use the docker image from linuxserver/tvheadend. I exported the settings of the container and added the following in the linuxserver-tvheadend.json, and recreated the container by importing the settings:


 "devices" : [
{
"CgroupPermissions" : "rwm",
"PathInContainer" : "/dev/dri",
"PathOnHost" : "/dev/dri"
},
{
"CgroupPermissions" : "rwm",
"PathInContainer" : "/dev/dvb",
"PathOnHost" : "/dev/dvb"
}
],

Now go to TVH > About > togle details

and see what is situation with VAAPI

if yes
go to Settings > stream > codec profiles and add needed


h264_vaapi: H.264/AVC (VAAPI)
hevc_vaapi: H.265/HEVC (VAAPI)
vp8_vaapi: VP8 (VAAPI)
vp9_vaapi: VP9 (VAAPI)

Pieter Hooftman

Sorry i wasn't clear, but already done that. Hardware acceleration is working (VAAPI) from the docker container, using the /dev/dri/renderD128 device on the host
