Anton Khirnov dff3a283cd fftools/ffmpeg: rework -enc_time_base handling 
Read the timebase from FrameData rather than the input stream. This
should fix #10393 and generally be more reliable.

Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.
