The purpose of this function is to allocate a buffer that is optimal to

provide a hardware buffer in order to avoid additional memcpy operations.
The function can return a buffer that has caps different from the requested

If a format change was requested, the returned buffer will be one to hold
the data of said new caps, so its size might be different from the requested

the @buf is NULL, a #GstBuffer will be created with @caps, @offset and @size.

can be used together.
A non flushing seek might take some time to perform as the currently
playing data in the pipeline will not be cleared.
An accurate seek might be slower for formats that don't have any indexes
or timestamp markers in the stream. Specifying this flag might require a
complete scan of the file in those cases.
no EOS will be emmited by the element that performed the seek, but a
#GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
When this message is posted, it is possible to send a new seek event to
continue playback. With this seek method it is possible to perform seemless
looping or simple linear editing.
When doing fast forward (rate &gt; 1.0) or fast reverse (rate &lt; -1.0) trickmode
playback, the @GST_SEEK_FLAG_SKIP flag can be used to instruct decoders
and demuxers to adjust the playback rate by skipping frames. This can improve
performance and decrease CPU usage because not all frames need to be decoded.</doc>
