0c25863253 jpegdec: avoid crashing on invalid input without components 2011-07-04 14:32:27 +02:00

2f94df8032 jpegenc: Don't round up size of encoded buffers 
For some reason, in code dating to 2001, encoded jpeg buffers were
rounded up to multiples of 4 bytes.  With the added bonus that the
extra bytes are unwritten, causing valgrind issues.  Oops.  I can't
think of any reason why JPEG buffers need to be multiples of 4 bytes,
so I removed the padding.  There might be some code somewhere that
depends on this behavior, so if this needs to be reverted, please fix
the valgrind issues.

098cf89e34 jpegenc: pulsesink: raw1394: Address unused but set variables 
GCC 4.6.x spits warnings about such usage of variables. The variables in
raw1394 were marked with G_GNUC_UNUSED as this seemed omre appropriate.
The others were removed.

dcbba0932d jpegenc: sink pad's getcaps shouldn't use the src pad getcaps 
Instead of using get_allowed_caps on the srcpad, the sinkpad getcaps
should use the getcaps of the srcpad's peer. This way the srcpad
can keep using fixed_caps and sinkpad getcaps exposes all caps
that can be negotiated

addbc3c4ca jpegdec: add "max-errors" property to ignore decoding errors 
Add property to ignore decoding errors. Default is to ignore a few
decoding errors if the input is packetized, but error out immediately
if the input is not packetized.

Ignoring errors for packetized input most likely doesn't work
properly yet, so don't do that for now.

cec48383b1 jpegdec: more sanity checks on input 
Specifically, verify input components / colour space is as code

Presently, that means 3 components YCbCr colour space, and somewhat
limited sampling factors.

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.

74ac172bc2 jpegenc: should not return caps ANY based on downstream
