Gyan Doshi 84556ef059 lavu/timecode: clarify error msg for timecode_rate 
The user-supplied value for timecode_rate in drawtext is rounded
to nearest integer. So, a supplied value of 0.49 or lower is rounded to 0.
This throws a misleading error message which says "Timecode frame rate must be
specified". Changed message to account for values under one.

Also noted supported framerates for drop TC.

Michael Niedermayer b46dcd5209 avutil/timecode: Fix fps check 
The fps variable is explicitly set to -1 in case of some errors, the check must
thus be signed or the code setting it needs to use 0 as error code
the type of the field could be changed as well but its in an installed header

Fixes: integer overflow
