Sure, looks like gmail is complying with a plaintext email RFC. Let me try

One of them would have a software-defined radio subsystem, the other
not.

Hi Scott,
LGTM.
I will push soon and fix the APIchanges on the way.
Apologies for the delay on this simple patch.
Had a lot of issues getting the machine up and running.
I was able to capture a sample finally and test this out.
I wanted to test it to get an idea of how EIA-608 travels through th

Dear list,
I made a patch for the delogo filter. With this I can create a circular
or elliptic zone to apply the delogo algorithm. The borders are defined with
x,y,w,h parameter just like the rectangular area definition. To become
circular I added an additional parameter 'r'=0/1 defaulting to '0'
Added a description of the elliptic formed delogo algorithm. Placed it
outside the doxygen function comment.

Currently, if there is a hardware encode failure, the numeric
error code will be printed making it somewhat hard to get to
the root cause of the issue. Print the readable message generated
by av_err2str() instead.
