projects.vdr-developer.org downtime

Hello!

Today some bots, probably from China, brought the
projects.vdr-developer.org webserver to it's knees.

Because they don't identify them selfs as bots, I finally had to blacklist
their whole IP range.

I hope everything runs smooth now. Sorry for any inconvenience.

Whenever you experience problems with projects.vdr-developer.org, just
drop me a mail (vdr <AT> e-tobi.net)

Where do you take that time offset value from? I'm also working on such
kind of scripts right now, because I want to remux especially HD
recordings to MKV. In the case of movies broadcasted by ARD HD or ZDF HD
(720p <at> 50Hz), they are full of so-called filler-NALUs, which can be
removed just by muxing into MKV not directly by ffmpeg, but by mkvmerge,
which shrinks a 10GB movie to about 3GB. My problem is still A/V sync,
all the original TS chunks (I also record into 200MB pieces, because of

So for now you're determining that value sort of experimentally?

Yes, I'm demuxing all the 000xy.ts files in all their component streams
with ffmpeg for now first, then multiplex the ones I want with mkvmerge.
I might switch to tsMuxeR, maybe also convert back to cleaned-up TS from
MKV also with tsMuxeR to make the smaller recording again playable by
VDR (I've read in the vdr-portal.de forum some users already
experimented with this).

By "simplified" you mean the merged ts?

update-xxv: Ask for password only once

Hi!

I found the three available options for specifying a password in the course of running update-xxv a 
little bit cumbersome, so I want to share the following patch with you.

In addition to the default (no password), -a for being asked for it with _each_ database access 
(wtf) and specifying it on the command line in clear text using -p, I add a new option -A that asks 
for a password only once and supplies it to mysql as if it was given with -p.

This by itself will not raise overall system security as the password is still given to each mysql 
call on the command line (and thus can be seen in the process table), however, it’s better to not 
have it in .bash_history.

Sorry, incomplete patch. Here is the right one (doesn’t give -a twice on the help screen).

Minor confusion in the manual

        -D num, --device=num
               Use  only  the  given  DVB  device  (num = 0, 1, 2...). 
There may be several -D
               options (by default all DVB devices will be used).

The way I first read that, to make it use device 1 and 2 and not 3, you 
would use:
-D 1, 2
or:
-D 1,2

But it seems you can't put more then one per "-D". You have to use:
-D 1 -D 2
