2010-06-10Detect toolchain based on gcc -dumpmachinePhilip Jägenstedt
Using uname fails e.g. on a 64-bit machine with a 32-bit toolchain. The following gcc -dumpmachine strings have been verified: * 32-bit Linux gives i486-linux-gnu * 64-bit Linux gives x86_64-linux-gnu * Mac OS X 10.5 gives i686-apple-darwin9 * MinGW gives mingw32 *darwin8* and *bsd* can safely be assumed to be correct, but *cygwin* is a guess.

2010-06-09Remove secondary mv clamping from decode stageJohn Koleszar
This patch removes the secondary MV clamping from the MV decoder. This behavior was consistent with limits placed on non-split MVs by the reference encoder, but was inconsistent with the MVs generated in the split case. The purpose of this secondary clamping was only to prevent crashes on invalid data. It was not intended to be a behaviour an encoder could or should rely on. Instead of doing additional clamping in a way that changes the entropy context, the secondary clamp is removed and the border handling is made implmentation specific. With respect to the spec, the border is treated as essentially infinite, limited only by the clamping performed on the near/nearest reference and the maximum encodable magnitude of the residual MV. This does not affect any currently produced streams. Change-Id: I68d35a2fbb51570d6569eab4ad233961405230a3

2010-06-05shared library support (.so)John Koleszar
This patch adds support for building shared libraries when configured with the --enable-shared switch. Building DLLs would require more invasive changes to the sample utilities than I want to make in this patch, since on Windows you can't use the address of an imported symbol in a static initializer. The best way to work around this is proably to build the codec interface mapping table with an init() function, but dll support is of questionable value anyway, since most windows users will probably use a media framework lib like webmdshow, which links this library in staticly.

2010-06-02Add support for reading YUV4MPEG2 files to ivfenc.Timothy B. Terriberry
A large collection of example files may be found at http://media.xiph.org/video/derf/ This also fixes a bug in ivfenc for uncompressed IVF input, which previously appeared not to skip past the file header the second time it opened the file. I don't actually have an IVF file with which to test this fix, however. Change-Id: Id69a1e11a3fa16c4a4fa8944e880bcea090cd52b

2010-06-01Remove costly memory reads/writes in vp8_reset_mb_tokens_context()Yunqing Wang
Tests on x86 showed this function costed 2.7% of total decoding time because of all the memory reads/writes. After modification, it only costs about 0.7% of decoding time, which gives a 2% gain. Change-Id: I5003ee30b6dc6dea0bfa42a6ad7e7c22fcc7b215

2010-05-27Increase the size of output packet listYaowu Xu
This is to accommodate output packets for both compressed data and psnr stats. For each frame, there are at least one packet for compressed data and one for psnr stats. For a max lag of 25, 64 is large enough to cover all lagged frames at the end of encoding. Change-Id: If20787fbc86f96e1aa16a3ccf2adc93e6c1e3d5f

2010-05-25examples: use I420 input for encodersJohn Koleszar
The output of simple_decoder, as well as the default format for the ivf{enc,dec} tools, is I420. The encoder examples are changed to default to I420 as well. This is desirable because passing the output of simple_encoder to simple_decoder would otherwise have the chroma planes flipped, which is unexpected.

2010-05-24install includes in DIST_DIR/include/vpx, move vpx_codec/ to vpx/John Koleszar
This renames the vpx_codec/ directory to vpx/, to allow applications to more consistently reference these includes with the vpx/ prefix. This allows the includes to be installed in /usr/local/include/vpx rather than polluting the system includes directory with an excessive number of includes.

2010-05-24make: make install target behave as expectedJohn Koleszar
Split the 'make install' target into two: install and dist. dist retains the old make install behavior of building a "distribution" release, with source files, build system, etc. install does what one one expects -- installs into a tree in the filesystem, /usr/local by default.
