Wim Taymans e72a01e949 video-converter: Add support for 16 bits formats 
Rework the way we track the current state of the video through the
different conversion phases and use this to make sure we use the right
format and pstride where needed.

Wim Taymans 2f38f83c08 video-orc: comment out unused function 
A faster version of 4tap horizontal scaling causes segfaults in ORC
presumably because it uses too many registers so disable it to avoid
crashing in the ORC tests.

Tim-Philipp Müller f04a9589d4 video: add video blend helper functions to docs 
I don't think those were ever meant to be made public,
but they are, so we might as well document them.

Wim Taymans b3ff9c030f video-converter: align offsets to subsampling 
Only apply an offset that is a multiple of the subsampling. To handle
arbitrary offsets in the future, we need to be able to chroma-resample
part of the borders.

Vincent Penquerc'h a16cd5d2a5 vorbisenc: push an updated segment stop time when we know it 
When encoding, libvorbis will tell us how many samples are encoded
in the buffer it returns. This number may be less than the maximum
of samples in the block, if this is the last packet. In we have no
segment end time, we set it to the end time of that last sample to
tell downstream that the buffer contains less samples.

Vincent Penquerc'h aa5b5b9085 oggmux: set correct granpos on last page when samples are clipped 
Samples may be clipped at the end, and this is conveyed by a
granulepos that's smaller than it would otherwise be. Use the
segment stop time to detect this, and calculate the right
granulepos.
 2014-10-30 14:28:39 +00:00
Vincent Penquerc'h a93cc13d42 oggdemux: fix last buffer timestamp when samples are clipped 
The end of a stream can be clipped by setting the granulepos of
the last page to a lower value that it otherwise would be.

Vincent Penquerc'h e107ba97e2 gst-discoverer: error out on failure to copy 
This should not really fail, but let's check return value
anyway as it guards against future changes.

Wim Taymans 49d909dabf video-scaler: add more ORC functions 
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

Wim Taymans ca2bd1cc6b video-scaler: rename resampler to video-resampler 
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

Wim Taymans daf20d5e09 video-scaler: remove color range argument 
We just need to clip to the format limits, if there is extra headroom in
the range we can use that without problems.

not only the ones we know about.
