Forum: GNU Radio Anybody having QAM mod/demod.

Does anybody have QAM mod/demodulator working in loop back simulation. 
Mine in attached and doesn't work. Infact it's not able to send the 
video file. Can somebody give any suggestion to correct?
Regards.
Ahmed.

There was a bug in the QAM demodulator that has been recently fixed
(merged in two weeks ago).  Try checking out the current master or
next branch.

Also, what does
payload-length == 0 mean? "As big as it needs to be" or "Zero" ??

The 'master' branch contains bug fixes to the most recent release.

The 'next' branch also contains new features.

If you used the build-gnuradio script to install you should just be
able to go into the gnuradio directory and type 'git pull' to update
it.

If you installed it using a package manager you'll need to check out
the source using git.

git clone http://gnuradio.org/git/gnuradio.git

See http://gnuradio.org/redmine/projects/gnuradio/wiki...
for more info

Or http://gnuradio.org/redmine/projects/gnuradio/wiki/Download
which explains the branches, too.
