-// Simple Encoder
-// ==============
-//
-// This is an example of a simple encoder loop. It takes an input file in
-// YV12 format, passes it through the encoder, and writes the compressed
-// frames to disk in IVF format. Other decoder examples build upon this
-// one.
-//
-// The details of the IVF format have been elided from this example for
-// simplicity of presentation, as IVF files will not generally be used by
-// your application. In general, an IVF file consists of a file header,
-// followed by a variable number of frames. Each frame consists of a frame
-// header followed by a variable length payload. The length of the payload
-// is specified in the first four bytes of the frame header. The payload is
-// 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.
-//
-// 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.
-//
-// Updating The Configuration
-// ---------------------------------
-// Almost all applications will want to update the default configuration
-// with settings specific to their usage. Here we set the width and height
-// of the video file to that specified on the command line. We also scale
-// the default bitrate based on the ratio between the default resolution
-// and the resolution specified on the command line.
-//
-// Initializing The Codec
-// ----------------------
-// The encoder is initialized by the following code.
-//
-// Encoding A Frame
-// ----------------
-// The frame is read as a continuous block (size width * height * 3 / 2)
-// from the input file. If a frame was read (the input file has not hit
-// EOF) then the frame is passed to the encoder. Otherwise, a NULL
-// is passed, indicating the End-Of-Stream condition to the encoder. The
-// `frame_cnt` is reused as the presentation time stamp (PTS) and each
-// frame is shown for one frame-time in duration. The flags parameter is
-// unused in this example. The deadline is set to VPX_DL_REALTIME to
-// make the example run as quickly as possible.
-
-// Forced Keyframes
-// ----------------
-// Keyframes can be forced by setting the VPX_EFLAG_FORCE_KF bit of the
-// flags passed to `vpx_codec_control()`. In this example, we force a
-// keyframe every <keyframe-interval> frames. Note, the output stream can
-// contain additional keyframes beyond those that have been forced using the
-// VPX_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
-// encoder.
-//
-// Processing The Encoded Data
-// ---------------------------
-// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data
-// for this frame. We write a IVF frame header, followed by the raw data.
-//
-// Cleanup
-// -------
-// The `vpx_codec_destroy` call frees any memory allocated by the codec.
-//
-// Error Handling
-// --------------
-// This example does not special case any error return codes. If there was
-// an error, a descriptive message is printed and the program exits. With
-// few exeptions, vpx_codec functions return an enumerated error status,
-// with the value `0` indicating success.
-//
-// Error Resiliency Features
-// -------------------------
-// Error resiliency is controlled by the g_error_resilient member of the
-// configuration structure. Use the `decode_with_drops` example to decode with
-// frames 5-10 dropped. Compare the output for a file encoded with this example
-// versus one encoded with the `simple_encoder` example.
