+// 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.
