Sebastian Dröge	7548d5f7f9	openexrdec: Don't start scanning for the header from the start again each time ... This will be incredible slow if the upstream block size is very small. Instead continue scanning for the header where we previously stopped. For the standard filesrc block-size this made decoding a file about 3 times faster. https://bugzilla.gnome.org/show_bug.cgi?id=719890	2014-01-18 13:56:28 +01:00
Sebastian Dröge	a6bf25faa5	openexrdec: Instead of trying to parse the bitstream, just look for the next header ... This should be more robust and allows us to handle new versions of the file format if the library supports it.	2013-12-04 22:38:20 +01:00
Sebastian Dröge	de3abac8ed	openexrdec: Consider the pixel aspect ratio stored in the file	2013-11-23 19:11:42 +01:00
Sebastian Dröge	a90585c686	openexr: Add OpenEXR decoder element ... This currently converts from ARGB64_F16 (16 bit float per component) to ARGB64 by clipping. We should add support for the F16 format and implement a conversion filter element that can apply gamma curves, change exposure, etc.	2013-11-23 18:51:52 +01:00
