Sebastian Dröge 41b17ec2a7 videomixer: Fix assembly register constraints 
Fixes bug #608209.
 2010-01-27 16:35:10 +01:00
Stefan Kost 404e673ac0 videomixer: use 'q' constraint instead of 'r' 
This avoids the "bad register name `%dil'" compilation errors on 32bit where
because of 'r' gcc puts the value in a general purpose register and then tries
to access the lower part as %dil/%sil which is not existing on 32bit. 'q' requests
a-d registers
 2010-01-13 16:48:46 +02:00
Sebastian Dröge 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.
 2010-01-11 19:32:35 +01:00
Sebastian Dröge 6158f401a1 videomixer: Add MMX implementations for I420 and all non-alpha RGB formats 2010-01-11 18:37:45 +01:00
Sebastian Dröge 2950262186 videomixer: Refactor processing functions 
This allows easier plugging of optimized processing functions
in the future, like for SSE or AltiVec.
 2010-01-11 18:37:44 +01:00
Wim Taymans 362785df88 videomixer: optimize blend code some more 
Use more efficient formula that uses less multiplies.
Reduce the amount of scalar code, use MMX to calculate the desired
alpha value.
Unroll and handle 2 pixels in one iteration for improved pairing.
 2009-12-25 12:38:45 +01:00
Wim Taymans 4f9ded7742 videomixer: scale and clamp 
Scale and clamp to the max alpha values.
 2009-12-24 22:59:09 +01:00
Wim Taymans 3c0f18d765 videomixer: some trivial cleanups 2009-12-24 21:45:12 +01:00
Sebastian Dröge 3ac6f5e48b videomixer: Fix assembly compilation on x86 
Fixes bug #604814.
 2009-12-17 18:14:55 +01:00
Sebastian Dröge 0a0f7ecc16 videomixer: Use movzbl instead of movzxb for moving one byte to a l register 
For some reason latest gcc/binutils accept movzxb here while
movzbl would be correct and is the only thing accepted by older
gcc/binutils.

Fixes bug #604679.
 2009-12-16 10:50:32 +01:00
Sebastian Dröge 9e45038d8d videomixer: src/dest are input and output of the AYUV blending MMX assembler 2009-12-16 06:59:01 +01:00
Sebastian Dröge 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.
 2009-12-15 12:30:21 +01:00
Sebastian Dröge 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 760eaf7b2a videomixer: Fix stupid mistake in last commit 2009-12-11 13:11:12 +01:00
Sebastian Dröge 089d9d9dba videomixer: Don't do floating point math in the inner processing loop for I420 blending 2009-12-11 12:36:42 +01:00
Sebastian Dröge 6f51dfba95 videomixer: Remove wrong comments, copied from the I420 blend function 2009-12-10 10:48:49 +01:00
Sebastian Dröge 93089ef445 videomixer: The queued duration is a signed integer 
...and it will really be negative sometimes.
 2009-12-09 21:15:07 +01:00
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.
 2009-12-09 21:03:57 +01:00
Sebastian Dröge b0f8978fd8 videomixer: Use gst_util_uint64_scale_int() for fps to seconds per frame calculations 2009-12-09 16:15:09 +01:00
Tim-Philipp Müller 0506545b04 videomixer: fix up Makefile some more 
Remove CFLAGS from LIBADD and make order of the various CFLAGS and
LIBS at least consistent with each other.
 2009-09-22 11:02:02 +01:00
Brian Cameron 341be447a6 videomixer: Add $(GST_PLUGINS_BASE_LIBS) to LDFLAGS for linking libgstvideo 
Fixes bug #595897.
 2009-09-22 08:09:39 +02:00

Sebastian Dröge 0775db4455 videomixer: Remove some redundant checks and error out immediately if not negotiated 
Also stop leaking the output buffer in some error cases.
 2009-07-10 17:33:40 +02:00
Sebastian Dröge 4ccd9c92ae videomixer: Remove the calculate_frame_size() function and use libgstvideo instead 2009-07-10 17:23:03 +02:00
Edward Hervey 34c97c0c6f videomixer: Remove unused link/unlink pad methods 2009-07-10 14:37:16 +02:00
Edward Hervey b02949faeb videomixer: I420 mode: Add fast path for 0.0 and 1.0 alpha 
If the source alpha is 0.0, we take nothing.
If the source alpha is 1.0, we overwrite everything.
 2009-07-10 14:37:13 +02:00
Edward Hervey 3c88249d48 videomixer: I420 blending : Fix main algorithm. 
When blending a source layer with an alpha of 'a' on top of another
destination layer we take the sum of:
* 'a' percent of the source layer
* (100 - 'a') percent of the destination layer (the remainder)
 2009-07-10 14:37:10 +02:00
Edward Hervey ace4cb2295 videomixer: Make debugging category global to all the code. 2009-07-10 14:37:07 +02:00

For this we a) implement the checkers filling and b)
actually blend the src/dest by using the src alpha value
from the pad.
 2009-05-28 13:35:52 +02:00
