The default is -1, it is equivalent to 1 if the format was automatically
probed and 0 otherwise.
@item auto_convert
If set to 1, try to perform automatic conversions on packet data to make the
streams concatenable.
Currently, the only conversion is adding the h264_mp4toannexb bitstream
filter to H.264 streams in MP4 format. This is necessary in particular if
there are resolution changes.

A 1 character description of the current picture type.
@item pts
The timestamp of the current frame, in seconds, with microsecond accuracy.
The timestamp of the current frame.
It can take up to two arguments.
The first argument is the format of the timestamp; it defaults to @code{flt}
for seconds as a decimal number with microsecond accuracy; @code{hms} stands
for a formatted @var{[-]HH:MM:SS.mmm} timestamp with millisecond accuracy.
The second argument is an offset added to the timestamp.
