It takes a 2-spatial-layer +// input file +// containing the compressed data (in OBU format), passes it through the +// decoder, and writes the decompressed frames to disk. The base layer and +// enhancement layers are stored as separate files, out_lyr0.yuv and +// out_lyr1.yuv, respectively. +// +// Standard Includes +// ----------------- +// For decoders, you only have to include `aom_decoder.h` and then any +// header files for the specific codecs you use. In this case, we're using +// av1. +// +// Initializing The Codec +// ---------------------- +// The libaom decoder is initialized by the call to aom_codec_dec_init(). +// Determining the codec interface to use is handled by AvxVideoReader and the +// functions prefixed with aom_video_reader_. Discussion of those functions is +// beyond the scope of this example, but the main gist is to open the input file +// and parse just enough of it to determine if it's a AVx file and which AVx +// codec is contained within the file. +// Note the NULL pointer passed to aom_codec_dec_init(). We do that in this +// example because we want the algorithm to determine the stream configuration +// (width/height) and allocate memory automatically. +// +// Decoding A Frame +// ---------------- +// Once the frame has been read into memory, it is decoded using the +// `aom_codec_decode` function. The call takes a pointer to the data +// (`frame`) and the length of the data (`frame_size`). No application data +// is associated with the frame in this example, so the `user_priv` +// parameter is NULL. The `deadline` parameter is left at zero for this +// example. This parameter is generally only used when doing adaptive post +// processing. +// +// Codecs may produce a variable number of output frames for every call to +// `aom_codec_decode`. These frames are retrieved by the +// `aom_codec_get_frame` iterator function. The iterator variable `iter` is +// initialized to NULL each time `aom_codec_decode` is called. +// `aom_codec_get_frame` is called in a loop, returning a pointer to a +// decoded image or NULL to indicate the end of list. +// +// Processing The Decoded Data +// --------------------------- +// In this example, we simply write the encoded data to disk. It is +// important to honor the image's `stride` values. +// +// Cleanup +// ------- +// The `aom_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 exceptions, aom_codec functions return an enumerated error status, +// with the value `0` indicating success. + +#include <stdio.h> +#include <stdlib.h> +#include <string.h> + +#include "aom/aom_decoder.h" +#include "aom/aomdx.h" +#include "common/obudec.h" +#include "common/tools_common.h" +#include "common/video_reader.h" + +static const char *exec_name; + +#define MAX_LAYERS 5 + +void usage_exit(void) { + fprintf(stderr, "Usage: %s <infile>\n", exec_name); + exit(EXIT_FAILURE); +} + +int main(int argc, char **argv) { + int frame_cnt = 0; + FILE *outfile[MAX_LAYERS]; + char filename[80]; + aom_codec_ctx_t codec; + const AvxInterface *decoder = NULL; + FILE *inputfile = NULL; + uint8_t *buf = NULL; + size_t bytes_in_buffer = 0; + size_t buffer_size = 0; + struct AvxInputContext aom_input_ctx; + struct ObuDecInputContext obu_ctx = { &aom_input_ctx, NULL, 0, 0, 0 }; + aom_codec_stream_info_t si; + uint8_t tmpbuf[32]; + unsigned int i; + + exec_name = argv[0]; + + if (argc != 2) die("Invalid number of arguments."); + + if (!(inputfile = fopen(argv[1], "rb"))) + die("Failed to open %s for read.", argv[1]); + obu_ctx.avx_ctx->file = inputfile; + obu_ctx.avx_ctx->filename = argv[1]; + + decoder = get_aom_decoder_by_index(0); + printf("Using %s\n", aom_codec_iface_name(decoder->codec_interface())); + + if (aom_codec_dec_init(&codec, decoder->codec_interface(), NULL, 0)) + die_codec(&codec, "Failed to initialize decoder."); + + if (aom_codec_control(&codec, AV1D_SET_OUTPUT_ALL_LAYERS, 1)) { + die_codec(&codec, "Failed to set output_all_layers control."); + } + + // peak sequence header OBU to get number of spatial layers + const size_t ret = fread(tmpbuf, 1, 32, inputfile); + if (ret != 32) die_codec(&codec, "Input is not a valid obu file"); + si.is_annexb = 0; + if (aom_codec_peek_stream_info(decoder->codec_interface(), tmpbuf, 32, &si)) { + die_codec(&codec, "Input is not a valid obu file"); + } + fseek(inputfile, -32, SEEK_CUR); + + if (!file_is_obu(&obu_ctx)) + die_codec(&codec, "Input is not a valid obu file"); + + // open base layer output yuv file + snprintf(filename, sizeof(filename), "out_lyr%d.yuv", 0); + if (!(outfile[0] = fopen(filename, "wb"))) + die("Failed top open output for writing."); + + // open any enhancement layer output yuv files + for (i = 1; i < si.number_spatial_layers; i++) { + snprintf(filename, sizeof(filename), "out_lyr%d.yuv", i); + if (!(outfile[i] = fopen(filename, "wb"))) + die("Failed to open output for writing."); + } + + while (!obudec_read_temporal_unit(&obu_ctx, &buf, &bytes_in_buffer, + &buffer_size)) { + aom_codec_iter_t iter = NULL; + aom_image_t *img = NULL; + if (aom_codec_decode(&codec, buf, bytes_in_buffer, NULL)) + die_codec(&codec, "Failed to decode frame."); + + while ((img = aom_codec_get_frame(&codec, &iter)) != NULL) { + aom_image_t *img_shifted = + aom_img_alloc(NULL, AOM_IMG_FMT_I420, img->d_w, img->d_h, 16); + img_shifted->bit_depth = 8; + aom_img_downshift(img_shifted, img, + img->bit_depth - img_shifted->bit_depth); + if (img->spatial_id == 0) { + printf("Writing base layer 0 %d\n", frame_cnt); + aom_img_write(img_shifted, outfile[0]); + } else if (img->spatial_id <= (int)(si.number_spatial_layers - 1)) { + printf("Writing enhancement layer %d %d\n", img->spatial_id, frame_cnt); + aom_img_write(img_shifted, outfile[img->spatial_id]); + } else { + die_codec(&codec, "Invalid bitstream.

It takes two input files in +// YV12 format, passes it through the encoder, and writes the compressed +// frames to disk in OBU format. +// +// 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. +// +// 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. + +// Forced Keyframes +// ---------------- +// Keyframes can be forced by setting the AOM_EFLAG_FORCE_KF bit of the +// flags passed to `aom_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 +// AOM_EFLAG_FORCE_KF flag because of automatic keyframe placement by the +// encoder. +// +// Processing The Encoded Data +// --------------------------- +// Each packet of type `AOM_CODEC_CX_FRAME_PKT` contains the encoded data +// for this frame. We write a IVF frame header, followed by the raw data. +// +// Cleanup +// ------- +// The `aom_codec_destroy` call frees any memory allocated by the codec. +// +// Error Handling +// -------------- +// This example does not special case any error return codes.

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. + +// Forced Keyframes +// ---------------- +// Keyframes can be forced by setting the AOM_EFLAG_FORCE_KF bit of the +// flags passed to `aom_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 +// AOM_EFLAG_FORCE_KF flag because of automatic keyframe placement by the +// encoder. +// +// Processing The Encoded Data +// --------------------------- +// Each packet of type `AOM_CODEC_CX_FRAME_PKT` contains the encoded data +// for this frame. We write a IVF frame header, followed by the raw data. +// +// Cleanup +// ------- +// The `aom_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, aom_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 "aom/aom_encoder.h" +#include "common/tools_common.h" +#include "common/video_writer.h" + +static const char *exec_name; + +void usage_exit(void) { + fprintf(stderr, + "Usage: %s <codec> <width> <height> <infile> <outfile> " + "<keyframe-interval> <error-resilient> <frames to encode>\n" + "See comments in simple_encoder.c for more information.\n", + exec_name); + exit(EXIT_FAILURE); +} + +static int encode_frame(aom_codec_ctx_t *codec, aom_image_t *img, + int frame_index, int flags, AvxVideoWriter *writer) { + int got_pkts = 0; + aom_codec_iter_t iter = NULL; + const aom_codec_cx_pkt_t *pkt = NULL; + const aom_codec_err_t res = + aom_codec_encode(codec, img, frame_index, 1, flags); + if (res != AOM_CODEC_OK) die_codec(codec, "Failed to encode frame"); + + while ((pkt = aom_codec_get_cx_data(codec, &iter)) != NULL) { + got_pkts = 1; + + if (pkt->kind == AOM_CODEC_CX_FRAME_PKT) { + const int keyframe = (pkt->data.frame.flags & AOM_FRAME_IS_KEY) != 0; + if (!aom_video_writer_write_frame(writer, pkt->data.frame.buf, + pkt->data.frame.sz, + pkt->data.frame.pts)) { + die_codec(codec, "Failed to write compressed frame"); + } + printf(keyframe ?
