The VideoLAN Forums

Hi all

First of all : thanks so much for the famous VLC player!

I run gentoo and upgraded vlc from 2.1.5 to 2.2.0 ...
I have been streaming 2 dvb-t TV channels on the 192.168.168/24 LAN for years now as follows:
(in fact I can watch from WAN as well using port forwarding on the box doing NAT)

on streamer:
% nvlc dvb:// --dvb-bandwidth 8 --dvb-fec 9 --dvb-frequency 506000000 --dvb-guard 8 --dvb-hierarchy -1 --dvb-inversion 2 --dvb-modulation 16 --dvb-srate 0 --dvb-transmission 8 --ttl 4 --programs=4128,4112 --sout-standard-access=http --sout-standard-mux=ts --ts-es-id-pid --sout '#duplicate{dst=std{access=http,dst=192.168.168.241:4128},select="program=4128",dst=std{access=http,dst=192.168.168.241:4112},select="program=4112"}'


on clients:
% vlc http://192.168.168.241:4112
or
% vlc http://192.168.168.241:4128

*issue*: this no longer works with 2.2.0 ... clients show the URL in playlist mentioning [00:00] and that's it.
Perhaps the streaming syntax became obsolete?

If there is some way I can troubleshoot I would gladly try to do so.

Here is the portage emerge use

streamer ~ # emerge -pv vlc
These are the packages that would be merged, in order:
Calculating dependencies... done!

Please share both logs.

thanks Jean-Baptiste
I would be happy to provide streamer and receiver logs. Not sure how to create them though... I tried:
on streamer
--logfile /tmp/streamer.log
on receiver
--logfile /tmp/receiver.log
but those would not create logs. For sure I must be missing something. Please enlighten me.

-vvv

-vvv

Hi Jean-Baptiste: sorry, I should have guessed the '-vvv'
Now I have another silly forum beginner question: how do I attach the logs to this thread?
The logs ar too big, I assume (thousands of lines) to paste here as text.
I can also email them or make them available on some ftp server.

PS: I have two streamer/receiver logs, one pair has a 2.1.5 receiver and one has a 2.2.0 receiver

here is a grep into the 2nd pair

# egrep -i "(fail|error|warn)" {receiver,streamer}-2.log

You need more logs.

Thanks Jean-Baptiste for your follow up.

I do have the full logs:
% ls -alrt /tmp/*.log

My question is: shall I just copy and paste ~10000 lines here or is there some way to upload files to the forum (or perhaps email them)?

As kindly suggested via PM :

vlc receiver log 1
http://pastebin.com/VmYncM4j
vlc receiver log 2
http://pastebin.com/N4PG98aP
vlc streamer log 1
http://pastebin.com/VhxBbWWD
vlc streamer log 2 head
http://pastebin.com/prC0zL9c
vlc streamer log 2 tail
http://pastebin.com/010gyPuU

note that last one was >512K so I split it in head and tail

I tried to stream a file

if on steamer I do
% vlc /data/mythtv/LiveTV/5112_20150316002301.mpg --sout '#rtp{dst=192.168.168.243,port=8484,sdp=rtsp://192.168.168.243:8484/test.sdp}'
then on receiver
% vlc rtsp://192.168.168.243:8484/test.sdp
works fine!

but

if on steamer I do
vlc /data/mythtv/LiveTV/5112_20150316002301.mpg --sout '#standard{access=http,dst=192.168.168.243:8484}'
then on receiver
vlc http://192.168.168.243:8484
does not work

perhaps syntax wrong?

I based command line on
https://www.videolan.org/doc/streaming- ... /ch04.html

Aternatively, is there a way to stream the 2 dvb-t channels muxed over rtp/rstp ?

What would be the command?

Recall, http command is:

nvlc -vvv dvb:// --dvb-bandwidth 8 --dvb-fec 9 --dvb-frequency 506000000 --dvb-guard 8 --dvb-hierarchy -1 --dvb-inversion 2 --dvb-modulation 16 --dvb-srate 0 --dvb-transmission 8 --ttl 4 --programs=4128,4112 --sout-standard-access=http --sout-standard-mux=ts --ts-es-id-pid --sout '#duplicate{dst=std{access=http,dst=192.168.168.243:4128},select="program=4128",dst=std{access=http,dst=192.168.168.243:4112},select="program=4112"}'

Thanks for hints

I don't see the issue on the streamers for HTTP.

And, no, your syntax is right.

All right then Jean-Baptiste, thanks for your valuable time.

Maybe I should then report on gentoo specific forum instead.
It must be that the 2.1.5->2.2.0 upgrade has resulted in http (but not rstp) to stop working on gentoo.

Is there, for now, a way to multiplex the dvb-t input using rstp as workaround?

I asked for correct syntax to do so. Basically: howto convert the http command into a rstp command (if possible)

Again: congratulations for the amazing VLC!

Same problem here.

2.2.0 can't HTTP stream anymore,
2.1.5, all fine,


2.2.0, errors, no stream,

AFAICT, streaming MPEG-TS inputs is broken in VLC 2.2.0. It seems to work with 3.0.0 development versions though.

Local playback works fine - DVB-C here.
