As a matter of principle, you are right.
But I decided to make it an internal module for the following practical
- The purpose is to make troubleshooting easier by reducing the possible
causes of problems. Having the stream in a separate tool means a few more
possible cause of problems: the test pattern needs to be muxed, piped and
then demuxed, causing possible A-V desync and pipe problems.
By the way, I have no idea what would be the best muxer to pipe raw RGB
video and PCM audio.
- People will never have the test pattern generator near at hand when they
need it, especially when people on the -users mailing-list tell them to
try it. This would cause some more mail exchanges.
Now, I would be perfectly happy to turn this test pattern generator into a
separate program (provided I get advice on the muxer to use), but I am
afraid this would impair its usefulness.
By the way, I totally agree with the fact that a test pattern generator has
nothing to do in a library of audio and video formats. But video4linux and
x11grab are not audio-video formats either, are they?
