[FFmpegMerger] Fix merger discard input timestamps

Some website save video-only and audio-only file with non-zero
timestamp. Therefore, when merging them, ffmpeg should keep original
timestamp.

According to ffmpeg doc: https://ffmpeg.org/ffmpeg.html

`-copyts`: Do not process input timestamps, but keep their values
without trying to sanitize them. In particular, do not remove the
initial start time offset value.
