 // your application. In general, an IVF file consists of a file header,

 // the raw compressed data.

 // Standard Includes
 // -----------------
 // For encoders, you only have to include `vpx_encoder.h` and then any
 // header files for the specific codecs you use. In this case, we're using
-// vp8. The `VPX_CODEC_DISABLE_COMPAT` macro can be defined to ensure
-// strict compliance with the latest SDK by disabling some backwards
-// compatibility features. Defining this macro is encouraged.

 // Getting The Default Configuration
 // ---------------------------------
 // Encoders have the notion of "usage profiles." For example, an encoder
 // may want to publish default configurations for both a video
 // conferencing application and a best quality offline encoder. These
 // obviously have very different default settings. Consult the
 // documentation for your codec to see if it provides any default
 // configurations. All codecs provide a default configuration, number 0,
 // which is valid for material in the vacinity of QCIF/QVGA.
