2012-11-07Rough merge of master into experimentalJohn Koleszar
Creates a merge between the master and experimental branches. Fixes a number of conflicts in the build system to allow *either* VP8 or VP9 to be built. Specifically either: $ configure --disable-vp9 $ configure --disable-vp8 --disable-unit-tests VP9 still exports its symbols and files as VP8, so that will be resolved in the next commit. Unit tests are broken in VP9, but this isn't a new issue. They are fixed upstream on origin/experimental as of this writing, but rebasing this merge proved difficult, so will tackle that in a second merge commit.

2012-06-29Build unit test driver from the default targetJohn Koleszar
We need an easy way to build the unit test driver without running the tests. This enables passing options like --gtest_filter to the executable, which can't be done very cleanly when running under `make test`. Fixed a number of compiler errors/warnings when building the tests in various configurations by Jenkins. Change-Id: I9198122600bcf02520688e5f052ab379f963b77b
2011-12-05Multiple-resolution encoderYunqing Wang
The example encoder down-samples the input video frames a number of times with a down-sampling factor, and then encodes and outputs bitstreams with different resolutions. Support arbitrary down-sampling factor, and down-sampling factor can be different for each encoding level. For example, the encoder can be tested as follows. 1. Configure with multi-resolution encoding enabled: ../libvpx/configure --target=x86-linux-gcc --disable-codecs --enable-vp8 --enable-runtime_cpu_detect --enable-debug --disable-install-docs --enable-error-concealment --enable-multi-res-encoding 2. Run make 3. Encode: If input video is 1280x720, run: ./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1 (output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180). The last parameter is set to 1/0 to show/not show PSNR.) 4. Decode: ./simple_decoder 1.ivf 1.yuv ./simple_decoder 2.ivf 2.yuv ./simple_decoder 3.ivf 3.yuv 5. View video: mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30 mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30 mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30 The encoding parameters can be modified in vp8_multi_resolution_encoder.c, for example, target bitrate, frame rate... Modified API. John helped a lot with that. Thanks! Change-Id: I03be9a51167eddf94399f92d269599fb3f3d54f5
2011-07-19Revert "Disable __longjmp_chk protection"John Koleszar
This reverts commit b73a3693e581583e9ec676f4396d0c3d173e2462. This version of the check doesn't work with generic-gnu, and figuring out the correct symbol version at configure time is probably more work than this is worth. May revisit in the future.

2011-07-13Disable __longjmp_chk protectionJohn Koleszar
glibc implements some checking on longjmp() calls by replacing it with an internal function __longjmp_chk(), when FORTIFY_SOURCE is defined. This can be problematic when compiling the library under one version of glibc and running it under another. Work around this issue for the one symbol affected for now, before taking out the undef hammer.

2010-09-23Add getter functions for the interface data symbolsJohn Koleszar
Having these symbols be available as functions rather than data is occasionally more convenient. Implemented this way rather than a get-codec-by-id style to avoid creating a link-time dependency between the encoder and the decoder.

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.
