Comment (by llogan):
Example input:
{{{
$ ./ffmpeg -f lavfi -i testsrc=d=30 trim.mp4
}}}
9219ec93b145725ac74fbfbde7f67ac5135b85cf creates an invalid output.
Behavior with current git master is the same. Using `starti` and `endi`
instead will produce correct output, but the *i options are not documented
in `doc/filters.texi`.
