I have troubles when trying to play DVB-T from a playlist.
I'm using five main frequencies each one is broadcasting several channels on a TS stream. So the idea is to put all of the needed parameters into a playlist so I don't have to use any VLC menu to switch frequencies.

I made a playlist which looks like this:

Code: Select all

#EXTM3U
#EXTVLCOPT:dvb-frequency=490000
#EXTVLCOPT:dvb-bandwidth=8
#EXTVLCOPT:sout=#duplicate{dst=display}
#EXTVLCOPT:sout-display-delay=1024
dvbt://

But when I'm trying to play it, it just doesn't work and I got these errors messages:

Code: Select all

main debug: creating new input thread
main debug: Creating an input for 'dvbt://'
main error: unsafe option "dvb-frequency" has been ignored for security reasons
main error: unsafe option "dvb-bandwidth" has been ignored for security reasons
main error: unsafe option "sout" has been ignored for security reasons
main error: unsafe option "sout-display-delay" has been ignored for security reasons

Why is it unsafe from a playlist but not when using the exact same parameters from the advanced options command line ?

This is with a M3U but I got the same behaviour with a XSPF.
I've tried with DVB-T only because I have no DVB-S/C hardware.

It is unsafe because VLC can open m3u files directly from internet. So it could be possible to do evil things with specially designed m3u files. That is why you need command line option that AFAIK has vanished to somewhere.

Argh, I've just noticed that it's also the same for dshow:// commands

Code: Select all

main debug: creating new input thread
main debug: Creating an input for 'TV2'
main error: unsafe option "dshow-vdev" has been ignored for security reasons
main error: unsafe option "dshow-adev" has been ignored for security reasons
main error: unsafe option "dshow-caching" has been ignored for security reasons
main error: unsafe option "dshow-fps" has been ignored for security reasons
main error: unsafe option "dshow-config" has been ignored for security reasons
main error: unsafe option "dshow-tuner" has been ignored for security reasons
main error: unsafe option "dshow-tuner-channel" has been ignored for security reasons
main error: unsafe option "dshow-tuner-country" has been ignored for security reasons
main error: unsafe option "dshow-tuner-input" has been ignored for security reasons

I'm used to used these in a playlist for my analog TV tuner as well and that worked fine in previous versions.

That is why you need command line option that AFAIK has vanished to somewhere.

That's not cool. There should be an option in the advanced preferences to allow these commands to work from a playlist which is the only way AFAIK to easily switch channels on such devices. Opening a menu each time you want to change channel is just plain annoying even though I understand the security reasons.
