      Multiple-resolution encoder · aa7335e6
      Yunqing Wang authored
      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!

      Adding error-concealment to the decoder. · d04f8523
      Stefan Holmer authored
      The error-concealer is plugged in after any motion vectors have been
      decoded. It tries to estimate any missing motion vectors from the
      motion vectors of the previous frame. Intra blocks with missing
      residual are replaced with inter blocks with estimated motion vectors.
      
      This feature was developed in a separate sandbox
      (sandbox/holmer/error-concealment).

      Generate a vpx.pc file for pkg-config. · 607f8420
      Ralph Giles authored
      Rules are added to libs.mk to generate a vpx.pc, which is
      installed as pkgconfig/vpx.pc under the target library directory.
      This also requires the install path prefix be exported directly
      in config.mk.
      
      Some systems use a tool called pkg-config to query information
      about intalled libraries or other resources, based on database
      files provided by the packages themselves at install time.
      
      Providing such a file for libvpx simplifies integration with
      other build systems, and provides an easy avenue for developers
      to test against their own builds of the library.

      Adds "armvX-none-rvct" targets · 11a222f5
      Tero Rintaluoma authored
      Adds following targets to configure script to support RVCT compilation
      without operating system support (for Profiler or bare metal images).
       - armv5te-none-rvct
       - armv6-none-rvct
       - armv7-none-rvct
      
      To strip OS specific parts from the code "os_support"-config was added
      to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
      specific parts such as OS specific includes and function calls for
      timers and threads etc. This was done to enable RVCT compilation for
      profiling purposes or running the image on bare metal target with
      Lauterbach.
      
      Removed separate AREA directives for READONLY data in armv6 and neon
      assembly files to fix the RVCT compilation. Otherwise
      "ldr <reg>, =label" syntax would have been needed to prevent linker
      errors. This syntax is not supported by older gnu assemblers.

      Add sparc-solaris-gcc as a build target. · 53f61ce2
      Aaron Watry authored
      Solaris 10 requires -lposix4 to build successfully on gcc. I only have a
      Sparc machine to test with on Solaris 10, but this change leaves
      OpenSolaris x86 in a usable state w/ gnu-generic.
      
      I am of the belief that this change should fix Solaris 10 on Sparc, but
      will leave other Solaris architectures as is. If someone has an x86
      Solaris 10 machine to test on, they may add x86-solaris-gcc to
      libvpx/configure and give it a go.

      nasm: add configure support · 7be093ea
      Jan Kratochvil authored
      yasm has to be preferred as currently nasm produces marginally less
      efficient code (longer opcodes). Filed for nasm as:
      https://sourceforge.net/tracker/?func=detail&atid=106208&aid=3037462&group_id=6208
      
      OTOH package should be built always the same, no matter which additional
      packages are / are not present on the system. As the package should be
      built with nasm (as yasm may not be available) we should not use yasm
      even if it is possibly available.
      
      nasm >= approx. 2.09 is required for the nasm compilation as the former
      versions had a section alignment bug.
      
      Provide nasm compatibility. No binary change by this patch with yasm on
      {x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
      {x86_64,i686}-fedora13-linux-gnu have been checked as safe.

      shared library support (.so) · 7aa97a35
      John Koleszar authored
      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.
