Sebastian Dröge ee2418effd video: Update disted orc source files 2014-12-12 10:02:43 +01:00
Sebastian Dröge 3fc5791b3f Revert "video-converter: Fix compiler warning because of missing prototype of non-static function" 
This reverts commit 406f32a946.

The problem was apparently that my video-orc.h was not updated and did not
include the prototype for that function. Only a "make clean" caused it to
be regenerated.

Thiago Santos fce946a1a3 audiodecoder: do not use fixed caps on source pad

use fixed caps. Having fixed caps can cause renegotiation issues.

Thibault Saunier 72c05d1cbb encodebin: Add a way to disable caps renegotiation for output stream format 
In some cases, the user might want the stream outputted by encodebin to
be in the exact same format during all the stream. We should let the
user specify when this is the case. This commit add some API in the
GstEncodingProfile to determine whether the format can be renegotiated
after the encoding started or not.

API:
    gst_encoding_profile_set_allow_dynamic_output
    gst_encoding_profile_get_allow_dynamic_output

Sebastian Dröge afcc0b3c50 video-frame: Mapping a frame with inconsistent values between GstVideoMeta and GstVideoInfo is a bug

bugs.

Tim-Philipp Müller 57811331de video-blend: make use of x offset when unpacking overlay image pixels 
Now that it's implemented we can use it, which is a minor
optimisation when the image to overlay gets cropped on the
left.

Tim-Philipp Müller 60d18149e5 video-format: sprinkle some 'restrict' keywords in pack/unpack functions 
In cases where we just call orc directly this is somewhat
superfluous, but let's do it anyway for consistency. In
other cases the compiler can hopefully use this to optimise
memory access a little.

Tim-Philipp Müller 9396d843d6 video-blend: fix clipping of overlay images on the left 
Fix clipping of images that are partially left of the video
surface, they would get clipped on the right side instead of
the left side, because the video unpack functions currently
ignore the x offset parameter. Work around that until that
is implemented.

Vineeth T M 9032c12e69 video-blend: fix blending of rectangles partially or fully outside of the video 
In case of overlay being completely or partially outside
the video frame, the offset calculations are not right,
which resulted in the overlay not being displayed as
expected, or crashes due to invalid memory access.

When the overlay rectangle is completely outside,
we need not render the overlay at all.

For partial display of overlay rectangles, src_yoff
was not being calculated, hence it was always clipping
the bottom half of the overlay, By calculating the
src_yoff, now the overlay is clipped properly.
