pts_wrap_bits defaults to 33 (like MPEG), that causes valid
timestamps to be unwrapped and become invalid.
Inspired by a patch by Wu Zhiqiang <mymoeyard@gmail.com>.

If a file does not have a known duration, this leads to the timestamps
starting over for the next file, causing non-monotonic timestamps.
To prevent this, track the duration during demuxing and use it to
determine the current file duration before opening the next file.

This is safer, as a selected demuxer could still mean that it was auto-detected

That makes the concat demuxer usable with MPEG-PS streams,
even when the streams in the different parts are detected
in different order.

ff_make_absolute_url() recognizes the "://" pattern usual
in HTTP-like protocols, but consider relative URLs starting
with just the protocol name or using the comma syntax for
