Get timing information for the data currently output.
The exact meaning of "currently output" depends on the format.
It is mostly relevant for devices that have an internal buffer and/or
work in real time.
@param s media file handle
@param stream stream in the media file
@paramout dts DTS of the last packet output for the stream, in stream
time_base units
@paramout wall absolute time when that packet whas output,
in microsecond
@return 0 if OK, AVERROR(ENOSYS) if the format does not support it
Note: some formats or devices may not allow to measure dts and wall
atomically.
