fftools/ffmpeg: stop using InputStream.pts for generating video timestamps

Browse Source 
This was added in 380db569287ba99d903b7629f209b9adc7fd2723 as a
temporary crutch that is not needed anymore. The only case where this
code can be triggered is the very first frame, for which InputStream.pts
is always equal to 0.
