This is useful for observing the error recovery -// features of the codec. -// -// Usage -// ----- -// This example adds a single argument to the `simple_decoder` example, -// which specifies the range or pattern of frames to drop. The parameter is -// parsed as follows: -// -// Dropping A Range Of Frames -// -------------------------- -// To drop a range of frames, specify the starting frame and the ending -// frame to drop, separated by a dash. The following command will drop -// frames 5 through 10 (base 1). -// -// $ ./decode_with_drops in.ivf out.i420 5-10 -// -// -// Dropping A Pattern Of Frames -// ---------------------------- -// To drop a pattern of frames, specify the number of frames to drop and -// the number of frames after which to repeat the pattern, separated by -// a forward-slash. The following command will drop 3 of 7 frames. -// Specifically, it will decode 4 frames, then drop 3 frames, and then -// repeat. -// -// $ ./decode_with_drops in.ivf out.i420 3/7 -// -// -// Extra Variables -// --------------- -// This example maintains the pattern passed on the command line in the -// `n`, `m`, and `is_range` variables: -// -// -// Making The Drop Decision -// ------------------------ -// The example decides whether to drop the frame based on the current -// frame number, immediately before decoding the frame. - -#include <stdio.h> -#include <stdlib.h> -#include <string.h> - -#include "aom/aom_decoder.h" -#include "aom/aomdx.h" -#include "common/tools_common.h" -#include "common/video_reader.h" - -static const char *exec_name; - -void usage_exit(void) { - fprintf(stderr, "Usage: %s <infile> <outfile> <N-M|N/M>\n", exec_name); - exit(EXIT_FAILURE); -} - -int main(int argc, char **argv) { - int frame_cnt = 0; - FILE *outfile = NULL; - aom_codec_ctx_t codec; - const AvxInterface *decoder = NULL; - AvxVideoReader *reader = NULL; - const AvxVideoInfo *info = NULL; - int n = 0; - int m = 0; - int is_range = 0; - char *nptr = NULL; - - exec_name = argv[0]; - - if (argc != 4) die("Invalid number of arguments."); - - reader = aom_video_reader_open(argv[1]); - if (!reader) die("Failed to open %s for reading.", argv[1]); - - if (!(outfile = fopen(argv[2], "wb"))) - die("Failed to open %s for writing.", argv[2]); - - n = (int)strtol(argv[3], &nptr, 0); - m = (int)strtol(nptr + 1, NULL, 0); - is_range = (*nptr == '-'); - if (!n || !m || (*nptr != '-' && *nptr != '/')) - die("Couldn't parse pattern %s.\n", argv[3]); - - info = aom_video_reader_get_info(reader); - - decoder = get_aom_decoder_by_fourcc(info->codec_fourcc); - if (!decoder) die("Unknown input codec."); - - 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."); - - while (aom_video_reader_read_frame(reader)) { - aom_codec_iter_t iter = NULL; - aom_image_t *img = NULL; - size_t frame_size = 0; - int skip; - const unsigned char *frame = - aom_video_reader_get_frame(reader, &frame_size); - ++frame_cnt; - - skip = (is_range && frame_cnt >= n && frame_cnt <= m) || - (!is_range && m - (frame_cnt - 1) % m <= n); - - if (!skip) { - putc('.', stdout); - if (aom_codec_decode(&codec, frame, frame_size, NULL)) - die_codec(&codec, "Failed to decode frame."); - - while ((img = aom_codec_get_frame(&codec, &iter)) != NULL) - aom_img_write(img, outfile); - } else { - putc('X', stdout); - } - - fflush(stdout); - } - - printf("Processed %d frames.\n", frame_cnt); - if (aom_codec_destroy(&codec)) die_codec(&codec, "Failed to destroy codec."); - - printf("Play: ffplay -f rawvideo -pix_fmt yuv420p -s %dx%d %s\n", - info->frame_width, info->frame_height, argv[2]); - - aom_video_reader_close(reader); - fclose(outfile); - - return EXIT_SUCCESS; -} |
