8e6b876e76 Check that collectpads exists before removing pad 
The core now calls release pad from finalize, at which point
the collectpads might have already been freed.

1c47115b8e videmixer: add a example showing how to use the child properties 
Show how to position and set the alpho of the videos on gst-launch.

bcfd60a8d2 videomixer2: Add videomixer2 element 
This is based on collectpads2 and is synchronizing
all streams based on the running time.

New features compared to old videomixer:
 * Synchronizing frames on the running time
 * Improved and simplified negotiation
 * Full QoS support
 * Variable framerate support

Fixes bug #626048, #624905.

6da14d0c41 videomixer: Optimize ARGB blending and implement BGRA blending with orc 
This now means, that we have absolutely no handwritten assembly anymore
in videomixer and it's also faster now when using SSE.

19c8226c6d videomixer: Fix pipeline in the documentation 
Make sure that we have the same color format on all streams, i.e. AYUV

Fixes bug #625452.

2ff87c0fb9 videomixer: if we're not linked downstream, we can do any format 
Stupid me, assuming _get_allowed_caps() would actually return the
pad templates if there was no peer.

Edward Hervey
d72a2fb6da videomixer: Don't return caps in get_caps() that will be rejected 
This commit basically puts _get_caps() in sync with accept_caps().

If we don't have a master pad OR the master pad caps aren't negotiated
then we just return the downstream allowed caps.

If we have a master pad with negotiated caps, we return those caps
with a free range of width/height/framerate

01abf5b94e videomixer: Implement sinkpad GetCapsFunction. 
This allows returning only the formats, width, height, framerate
and pixel-aspect-ratio that downstream can support.

caec8d9837 videomixer: fix timestamp problems 
When the pad with the highest framerate goes EOS, instead of not timestamping
output buffers, intepollate timestamps and durations from the last seen ones.

Fixes #608026

daa52708b3 videomixer: Implement basic QoS 
This drops frames if they're too late anyway before blending and all
that starts but QoS events are not forwarded upstream. In the future
the QoS events should be transformed somehow and forwarded upstream.

2950262186 videomixer: Refactor processing functions

061ededa36 videomixer: Add MMX implementations of the AYUV blending and color filling functions 
This provides a 20% speedup for blending and 100% for color filling.

The blending can probably be optimized even more.

66d3ac8fb7 videomixer: Dequeue current buffer on FLUSH_STOP and don't unref NULL buffers 
... NULL buffers shouldn't really happen anymore when popping the
buffer from GstCollectPads but better check for this and print a warning.
 2009-12-12 16:55:13 +01:00
Sebastian Dröge
93089ef445 videomixer: The queued duration is a signed integer 
...and it will really be negative sometimes.

Sebastian Dröge
7418dee253 videomixer: Only pop buffers from collectpads after they're fully consumed 
This decreases latency and memory usage because new buffers are only
accepted by collectpads if there's no queued buffer.
