Stefan Kost 566bd22435 jpegenc: also lift the arbitrary restrictions for width and height 
This was already done for jpegdec.
 2010-05-06 15:43:53 +03:00
Mark Nauwelaerts 52c71352e0 jpegdec: optimise buffer scanning 
Specifically, when needing more data, do not rescan from start next time
around, but resume from last position.

See also #583047.
 2010-04-30 17:49:24 +02:00
Mark Nauwelaerts 761b883f2c jpegdec: disregard superfluous lines when indirect decoding 2010-04-30 17:49:15 +02:00
Mark Nauwelaerts 78a2b22ed5 jpegdec: add support for RGB and grayscale color space 
Also refactor src caps negotiation and setting.
 2010-04-30 17:49:11 +02:00
Mark Nauwelaerts b0ac4a4560 jpegenc: support more colour spaces and some cleanups 2010-04-30 17:49:09 +02:00
Mark Nauwelaerts c5614dbb40 jpegenc: more generic sink getcaps 2010-04-30 17:49:05 +02:00
Mark Nauwelaerts cec48383b1 jpegdec: more sanity checks on input 
Specifically, verify input components / colour space is as code
subsequently expects, thereby avoiding crashes or otherwise bogus output.
Presently, that means 3 components YCbCr colour space, and somewhat
limited sampling factors.

Fixes #600553.
 2010-04-30 17:49:03 +02:00
Tim-Philipp Müller 6b2a0c7c46 jpegdec: don't crash if jpeg image contains more than three components 
Our code currently only handles a maximum of 3 components, so error
out for now if the image has more components than that.

Fixes #604106.
 2010-04-25 23:15:42 +01:00
Stefan Kost 7e5d4b0fa9 jpegdec: move macro to c source 
One less semi public symbol without namespace prefix in the headers.
 2010-04-08 13:40:36 +03:00
Thiago Santos b1984b72bb jpegenc: Fix getcaps function 
When creating the caps allowed to upstream using downstream
restrictions, use gst_pad_get_allowed_caps as that has the
usable formats and puts into it the width, height and framerate
fields. This avoids getting errors about getcaps returning
non subset caps of its pad template.

This error showed up on the metadata plugin unit test in -bad.
 2010-04-05 16:09:58 -03:00
André Dieb Martins 74ac172bc2 jpegenc: should not return caps ANY based on downstream 
When downstream has a sink pad with ANY caps, jpegenc should
treat it the same as NULL and return its template caps.

Fixes #614842
 2010-04-04 21:30:06 -03:00
Raimo Järvi 10f092dc61 jpegenc: Set correct getcaps/setcaps functions on srcpads and simplify them 
This fixes downstream negotiation, upstream negotiation isn't really
supported by jpegenc yet.

Fixes bug #613789.

Fixes bug #610483.
 2010-02-22 20:55:29 +01:00
Stefan Kost 45522aab46 jpegenc: add a fixme for handling other YUV variants 2010-02-16 10:15:22 +02:00
Stefan Kost a9f5bbe1ff jpeg: don't directly access message, some message have args 
This caused bogus messages, such as reported in bug #607471.
 2010-02-02 17:23:49 +02:00
Stefan Kost 8576a11dae Revert "v4l2src: don't deref NULL" 
This reverts commit 3d9d34bd60.
 2010-01-25 17:21:13 +02:00
Stefan Kost 3d9d34bd60 v4l2src: don't deref NULL 
Error out when the pool gets shutdown.
 2010-01-25 14:16:22 +02:00
Michael Smith e5b6c1324b jpegenc: when creating an overflow buffer, copy timestamps. 2010-01-23 15:32:48 -08:00
Peter van Hardenberg 701c7d4b2a jpegenc: enlarge buffer if libjpeg tells us it's out of space. Fixes buffer 
overflow on some high-quality, low-resolution jpeg encodes.
 2010-01-21 17:26:23 -08:00
Wim Taymans 384c4a2495 jpegdec: reset segment info after flush 
Reset the segment info after a flush. We use the segment for handling QoS and if
we don't reset the segment, QoS is basically disabled after a flushing seek.

Stefan Kost b753e177fb jpegenc: fix spelling in comment 2009-11-24 15:51:21 +02:00
Tim-Philipp Müller 7af7d93b27 jpegdec: free temporary buffer when changing state to NULL 
Free temporary allocations in the state change function and not
only when the object is finalised.
 2009-11-09 15:20:00 +00:00
Tim-Philipp Müller 26e7fe27d7 jpegdec: only allocate as much temporary memory as needed for indirect decoding 
When we can't decode directly into the output buffer, make our temp buffers
only as big as needed instead of allocating for the worst case scenario (well,
we still alloc more than strictly needed for some cases, but significantly
less than before).
 2009-11-09 15:18:58 +00:00
Stefan Kost e3e910e971 jpegdec: don't allocate big arrays on the stack 
Add the arrays to the instance data and allocate on first use.
 2009-11-03 17:49:24 +02:00
Tim-Philipp Müller c83ea23a03 jpegdec: fix branch hints 
Remove inappropriate branching hints and add some new ones.
 2009-10-16 13:41:45 +01:00
Tim-Philipp Müller 4fb3f2519c jpegdec: fix regression in indirect decode path 
Revert variable name back to what it was before the G_LIKELY was
added (in commit 69c24fb9). The code works better that way.
 2009-10-16 13:36:42 +01:00
Tim-Philipp Müller 0c92e70f6c jpegdec: fix regression with certain formats 
Fix regression introduced by previous commit (#598517).
 2009-10-16 13:00:12 +01:00
Tim-Philipp Müller 30cb82da96 jpegdec: don't use decompress structure members we shouldn't be using 2009-10-16 13:00:12 +01:00
Tim-Philipp Müller 19b4f66014 jpegdec: remove some unused members from jpegdec instance structure 2009-10-16 13:00:12 +01:00
Tim-Philipp Müller 87bd79f4ba jpegdec: fix bogus warning about discont flag on first buffer 
The very first buffer should always have the DISCONT flag set, no
need to warn about that. Only warn if we get a DISCONT buffer in
non-packetised mode and we already have some data.
 2009-10-13 01:10:59 +01:00
Tim-Philipp Müller 6ae6af9dab jpegdec: fix crash for unusual vertical chroma subsampling factors 
Fixes #597351.

Stefan Kost 86b8935b07 jpegdec: comment/logging cleanups and more branch guides 2009-10-06 17:46:49 +03:00
Stefan Kost b1feeee166 jpegdec: don't leak output buffers on decoding errors 
The setjmp handles libjpeg error. Free the outputbffer if we don't need it.
 2009-09-30 09:19:48 +03:00
Tim-Philipp Müller 477cb58640 jpegdec: fix 'unused variable' compiler warning when compiling with GST_DISABLE_GST_DEBUG 2009-09-29 00:01:59 +01:00
Stefan Kost 69c24fb991 jpeg: handle more libjpeg return values, add some more branch hints 
Also remove unused size variable in _chain().
 2009-09-28 17:25:35 +03:00
Alessandro Decina 195883b30a Fix compile warnings with gcc 4.0.1. 2009-09-22 15:04:36 +02:00
Stefan Kost 253f43203d jpegdec: add a G_UNLIKELY and put perf-cat log to code path that copies 2009-09-21 16:07:50 +03:00
Edward Hervey 65d90baf84 jpegdec: Avoid unnecessary processing until we have a full picture. 
This is for non-packetized mode, when we know the upstream size in bytes.
 2009-09-03 17:40:20 +02:00
Tim-Philipp Müller 68c4019057 smokeenc: don't crash when compiled against libjpeg7 
Set parameters so that we don't crash with libjpeg7. Based on
Stefan Kost's fix for jpegenc. Fixes #591951.
 2009-08-17 17:08:45 +01:00
Stefan Kost a07a575209 jpeg: use longer macro names to not clash with some stupid windows defines 
libjpeg headers pull some windows system inlcudes (on windows) that contain a
define for DEFAULT_QUALITY.
 2009-07-30 17:57:53 +03:00
Mark Nauwelaerts 7a89fb0468 jpegdec: when scanning for 0xff marker ends, ensure desired result 
Otherwise, any non 0xff byte at end of data would be mistaken for
a tag byte, and in case of a frame_len 0 tag subsequently lead to an
infinite loop.
 2009-07-28 16:18:38 +02:00
Stefan Kost 23967b03a7 jpeg: make encoder work with libjpeg v7 
We have to specify do_fancy_downsampling = FALSE in the encoder with did not exist before.
 2009-07-24 10:50:13 +03:00
Stefan Kost 11c93fc1df jpeg: code cleanups for encoder 
Remove some disabled code in encoder. Try #if 0'ed code and add comments about
why it is disabled. Move idct-method enum to jpeg.c and use in both encoder and
decoder. Add idct-method property to encoder.
 2009-07-21 10:04:36 +03:00
Philippe Normand a0de8567ca jpegdec: bump max size to 65535x65535
