[FFmpeg-devel] [PATCH 2/4] Change the PTS time base to AV_TIME_BASE before to process a frame in the filter chain, and change it back to the stream time base in the filtered frame.

[Stefano Sabatini]

This is required, since all the frames in the filterchain are supposed
to use a time base of AV_TIME_BASE.
