TVHeadend, pipe, sh script, ffmpeg, iptv error

Added by Rastislav Potocny over 6 years ago

Hi, I am trying to use pipe sh script in tvheadend but getting constantly error and IPTV mux with no scan data...

Here is my setup:
CoreELEC 8.95, TVheadend 4.2.6

In TVheadend, DVB inputs, IPTV, URL is:

pipe:///storage/downloads/sledovanitv.sh

sledovanitv.sh script looks like:

#!/bin/bash
ffmpeg -i "http://31.47.108.4:7909/moderntv/stream/prima/40-hls/live-media.m3u8?_cdn_session=XZY&_cdn_timestamp=XZY&_cdn_token=XZY" -f mpegts -vcodec copy -acodec copy pipe:1

This is failed in TVheadend:

Also when I even pipe from TVheadend just ffmpeg it works:

pipe:///storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg -i "http://31.47.108.4:7909/moderntv/stream/prima/40-hls/live-media.m3u8?_cdn_session=XZY&_cdn_timestamp=XZY&_cdn_token=XZY" -f mpegts -vcodec copy -acodec copy pipe:1

Only when I tried to use pipe *.sh script it fails, can somebody help me or point me to right direction ?

Thanks

With user and group used to start TVH?
Is they are same with use run script manual?

I do run script under root, see attached screen for available users in tvheadend, I am not logged under any user, just using IP and login to TVHeadend.

Is this related ?

Thanks

Tvh service is normally not run by root account.

service Use command:

/usr/bin/tvheadend -f -p /var/run/tvheadend.pid -u hts -g video

aka
user hts
group video

Thanks a lot for your input but I am bit novice to Linux...

What do I need to do with the command, execute on boot ? or use command somewhere in TVheadend ?

RE: TVHeadend, pipe, sh script, ffmpeg, iptv error - Added by Rastislav Potocny over 6 years ago

I did read and understand, tvheadend is running under user hts.

I still can not get this working, what to put to script for ffmpeg and what for URL.

Does pipe command need to change something ? Does script need to change ?

pipe:///storage/downloads/sledovanitv.sh

When I run from shell, it will not connect:

#!/bin/bash
su - root -c "ffmpeg -re -fflags +genpts -i http://31.47.108.7:7909/moderntv/stream/prima/40-hls/live-media.m3u8?_cdn_session=ZXY&_cdn_timestamp=ZXY&_cdn_token=ZXY -f mpegts -vcodec copy -acodec copy pipe:1 > asd.ts"

Also does not work:

#!/bin/bash
su - root -c "ffmpeg -re -fflags +genpts -i "http://31.47.108.7:7909/moderntv/stream/prima/40-hls/live-media.m3u8?_cdn_session=ZXY&_cdn_timestamp=ZXY&_cdn_token=ZXY" -f mpegts -vcodec copy -acodec copy pipe:1 > asd.ts"

This works:

#!/bin/bash
ffmpeg -re -fflags +genpts -i "http://31.47.108.7:7909/moderntv/stream/prima/40-hls/live-media.m3u8?_cdn_session=ZXY&_cdn_timestamp=ZXY&_cdn_token=ZXY" -f mpegts -vcodec copy -acodec copy pipe:1 > asd.ts

Thanks for help & finding way around however I am still concerned why I can't successfully execute script (ffmpeg) via pipe from tvheadend but it does work from shell
