> @saste: It maybe isn't a bug, but it's better to fix it to have a
cleaner usage. People who use ffmpeg already have to think about shell
escaping + this escaping because of the filter's inability to parse the
expression correctly. I'm just suggesting that this ticket shouldn't be
closed as fast as possible, just to lower the number of open/unresolved
tickets, but rather should be discussed more to find the best way to fix
this issue, because it is an issue and it should be fixed.
If it isn't a bug (and it isn't since that's the expected parser
behavior), then it should not be considered as such. Syntax enhancements
are possible, but they would break the current behavior. The {} thing may
be implemented at some point, but won't change the escaping problem since
you would still need to escape some special character ("}" or ")"), so it
would just move it to another level. Other solutions have been discussed
recently on the mailing list, just don't believe that there is some
"simple" silver-bullet solution. Also this is the kind of problem which
can not be easily marked as fixed, since different persons perceive the
problem in different ways.
