I thought that it would be necessary in the case where the video starts
a few seconds before the audio. Since I don't know how FFmpeg manages
that internally, I wanted to be sure not to get audio frames too soon.

In the case I just talked about and in the case that there is no audio
at all. Note that if there is a few seconds of video without audio, it
will schedule the video frames until the first audio frame is
interleaved by dts. It will then add it immediately.
