Hi there!
I made a new setup with an offline Mux with two DAB programmes (encoding, multiplexing, creating an ETI and mod.ini file without problems).
The first tests worked without problems on the HackRF. After the first tests I copied the configuration files to another, stronger computer, where i also made
some tests with the same configuration and an DAB+ Mux.It also worked up to I restarted my machine and then the problems began:

I got the folowing Error message: ERROR Could not set priority for modulator:1; Setting up timestamp decoder with 0 offset.
The interesting is, if I retry to start the modulator it is working sometimes (but not stable), but most of the time it isn´t.
Sometimes another there is another error: hackrf_open() failed: HACKRF_ERROR_NOT_FOUND (-5) .
But the HackRF is connected the whole time, and after pressing the reset button on the Rig, the "Hack not found" problem is gone.
The other problem still exists.
Working conditions an my side is a Intel Core2 Quad with 2.40GHz and 4GB Ram, running Debian. I also noticed, that after retry to start
odr-dabmod the computer is going to be very slow... I also tested the configuration on my other computer, but now there is also the same problem...
What did i wrong? I am already a litte bit disappointed because I tried so many different things and I could not find the problem...

Did you properly create the fifo on your second computer?
mpb
PS:
it might be interesting to switch to SoapySDR instead of
fifo+hackrf_transfer to drive the HackRF. See INSTALL for instructions,
doc/example.ini for configuration file settings.

Yes, I also created the fifo on the second computer, because at the beginning it worked it worked on the second computer too!
But I found a part solution maybe for the problem, I added the fifo with the commad mkfifo /tmp/ofdm.fifo again and now it is working. But the message
ERROR Could not set priority for modulator:1, Setting up timestamp decoder with 0 offset already exists.
I also got following message, when i stop the transmission with ctrl+c:
exit
[3] Datenübergabe unterbrochen (broken pipe) odr-dabmod mod.ini
I think I should really try SoapySDR, to test it...

Edit: I restarted the computer and all the problems are back again! ,-)
But at the first try with the restartet machine I got this message:
Failed to open file: /tmp/ofdm.fifo
I think it is really a problem with the pipe, or what do you mean?

It could be that the contents of /tmp/ are not kept between reboots, and so

your pipe gets deleted.
You're not forced to have the fifo in /tmp and you could move it elsewhere.

PS:
for the issue about the real-time priority, have a look a the guide. There
is a chapter in the system environment part that explains this.
PPS:
The "broken pipe" error is an intentional consequence of using a pipe (pipe
= FIFO). If you quit the read end (hackrf_transfer) of the pipe, the write
end (odr-dabmod) receives a SIGPIPE and quits.

Thanks Matthias for the hint with the real-time priority, that solved my problem with ERROR Could not set priority for modulator:1.
I also made some advanced configurations, incl. live encoding with vlc and jack and nearly everything works fine.
I have only two more problems! ;-)
If I want to start the mod I get different error messages, but after a two to three times retry it will work normaly.
Sometimes a retry brings no solution. So I deleted the ofdm.fifo file and created a new one and after that it worked again...
I also got the message WARN ZeroMQ buffer low: 4 elements ! and sometimes the signal disappears for a few seconds.
I reduced the signal loss by adjusting the ZeroMQ buffer at my .ini file, now it its better, but not perfect...
Attached some examples of my errors, when my mod does not start at the first try:
dab-pc@dab-pc:~$ odr-dabmod live.ini & hackrf_transfer -t /tmp/ofdm.fifo -f 174928000 -x 47 \ -a 1 -s 4096000 -b 1750000

The backslash in the hackrf_transfer command line is not part of the
options for hackrf_transfer, it just means "the options continue on the
next line". Don't put it if you have everything on one line.
For errors that are generated by hackrf_transfer itself, I cannot help
you much, you have to ask the HackRF people.

I made that command into a script file and found it advantageous to add two extra lines at the start 'rm /tmp/odfm.fifo' and 'mkfifo /tmp/odfm.fifo'. This ensures that odr-dabmod starts filling an empty file every time the test script is run. If the fifo file doesn't exist, e.g. on a new system, it's no big deal to get the warning message from the first 'rm' command.
