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. - -#include <stdio.h> -#include <stdlib.h> -#include <string.h> - -#include "enc.h" -#include "server.h" - -int vpx_encode_frame(vpx_codec_ctx_t *codec, vpx_image_t *img, int frame_index, int flags) { -  int got_pkts = 0; -  vpx_codec_iter_t iter = NULL; -  const vpx_codec_cx_pkt_t *pkt = NULL; -  const vpx_codec_err_t res = -      vpx_codec_encode(codec, img, frame_index, 1, flags, VPX_DL_REALTIME); -  if (res != VPX_CODEC_OK) die_codec(codec, "Failed to encode frame"); - -  while ((pkt = vpx_codec_get_cx_data(codec, &iter)) != NULL) { -    got_pkts = 1; - -    if (pkt->kind == VPX_CODEC_CX_FRAME_PKT) { -      const int keyframe = (pkt->data.frame.flags & VPX_FRAME_IS_KEY) != 0; -      if (send_frame(pkt->data.frame.buf, pkt->data.frame.sz, pkt->data.frame.pts) < 0) { -        die_codec(codec, "Failed to write compressed frame"); -      } -      fprintf(stderr, keyframe ?
