9ee60482b2 asfdemux: Support reverse playback
Support reverse playback for ASF format.
Parse packets and queue the payloads, then push
the payload buffer to decoder in reverse order.
Video buffers are pushed from KeyFrame to next
Keyframe.

1e74f611ee asfdemux: mo_size check bug fix. mo_size is not mandatory field.
So, don't need to check previous payload's mo_size and current
payload's mo_size when merging it.

53cfef3e0f asfdemux: Ignore parsing errors from broken packets
We should instead be counting the number of errors and exiting if
they're too numerous. This makes a number of broken ASF files playable.

3064bf4a86 asfdemux: fix performance issue, especially with high-bitrate streams
Two things were suboptimal from a performance point of view:

a) consider a large media object such as a video keyframe, which
   may be split up into multiple fragments. We would assemble
   the media object as follows:
     buf = join (join (join (frag1, frag2), frag3), frag4)
   which causes many unnecessary memcpy()s, and malloc/free,
   which could easily add up to a multiple of the actual object
   size. To avoid this, we allocate a buffer of the size needed
   from the start and copy fragments into that directly.

b) for every fragment to join, we would create a sub-buffer
   before joining it (which would discard the sub-buffer again),
   leading to unnecessary miniobject create/free churn.

made sure it's not NULL, so no need to do it again here; neither
the number nor the streams changed since the last time.

67f754a9ea asfpacket: Avoid using broken duration extension
Quite a few (broken?) files have a packet duration of 1ms, which is
most definitely wrong for either audio or video packets.

We therefore avoid using that value and instead use other metrics to
determine the buffer duration (like using the extended stream properties
average frame duration if present and valid).

417e3e0346 asfdemux: Make sure we don't end up with negative timestamps.
Some files have payload with timestamps smaller than the preroll duration.
Instead of blindly substracting the preroll value (and ending up with
insanely high timestamps on the outgoing buffers), we make sure we
never go below 0.

804f65e6db asfpacket: Fix pull-mode timestamping handling.
The problem that happens is the following:
* A packet with multiple payloads comes in
* Those payloads get handled one by one
* The first payload contains the first audio payload with timestamp A
* The second payload contains the first video (key)frame with timestamp V (where V < A)

With the previous code, the following would happen:
* the first payload gets processed, then passed to queue_for_stream
* queue_for_stream detects it's the first valid timestamp received and stores
  first_ts = A
* the second payload gets processed, then pass to queue_for_stream
* queue_for_stream detects the timestamp is lower than first_ts... and
  discards it... resulting in losing the first keyframe of the video stream

We've been having this issue for *ages*... it's just that nobody noticed it
that much with playbin. But with playbin2's aggresive multiqueue handling, this
will result in multiqueue not being able to preroll (because the video decoder will
be dropping a ton of buffers before (maybe) receiving the next keyframe).

Tested with over 200 asf files, and they all play the first frame correctly now,
even the most braindead ones.

Original commit message from CVS:

(gst_asf_demux_parse_packet):
If packet size is specified within the packet and smaller than
the actual packet size, don't parse beyond the size specified in
the packet (this makes us parse some cases of packets with single
compressed payloads cleanly, see e.g stream from #431318). Also
add a sanity check when parsing compressed single payloads.

some more work, like payload extensions parsing and proper flow
aggregation, and stream activation based on preroll. Stay tuned.
