Changes (by erikbs):

 * component:  undetermined => avformat


Comment:

 @flx90: Thank you, that looks like a much better workaround solution than
 using e.g. an underscore like I tried (lines consisting of plain spaces
 were just ignored).

 ----

 PS. Adding the component “avformat”, see my original post where I point
 out that libavformat/movenc.c is where a patch should be applied (the
 encoder fails to respect that subtitle lines and pauses lengths are
 restricted to INT_MAX - 1 μs).
