/* * twamr-tseq-enc is a test program for our AMR encoder: it reads raw * 16-bit PCM (matching 3GPP *.inp) as input and writes 3GPP *.cod * format as output, allowing libtwamr encoder to be tested with the * official test sequences. * * Both input and output are read/written in the host machine's * native byte order. */ #include <stdio.h> #include <stdint.h> #include <stdlib.h> #include <string.h> #include <strings.h> #include <unistd.h> #include "../libtwamr/tw_amr.h" static int read_input(inf, pcm, filename_for_errs) FILE *inf; int16_t *pcm; char *filename_for_errs; { int cc; cc = fread(pcm, 2, 160, inf); if (cc == 0) return 0; if (cc < 160) { fprintf(stderr, "warning: incomplete frame at the end of %s\n", filename_for_errs); return 0; } return 1; } main(argc, argv) char **argv; { char *infname, *outfname, *mode_arg; FILE *inf, *outf; struct amr_encoder_state *state; enum Mode mode_val; int16_t pcm[160]; struct amr_param_frame frame; uint16_t cod_words[AMR_COD_WORDS]; int opt, dtx = 0, vad2 = 0, use_mode_file = 0, rc; extern int optind; while ((opt = getopt(argc, argv, "d2")) != EOF) { switch (opt) { case 'd': dtx = 1; continue; case '2': vad2 = 1; continue; default: usage: fprintf(stderr, "usage: %s [-d] [-2] input.inp mode output.cod\n", argv[0]); exit(1); } } if (argc != optind + 3) goto usage; infname = argv[optind]; mode_arg = argv[optind+1]; outfname = argv[optind+2]; inf = fopen(infname, "r"); if (!inf) { perror(infname); exit(1); } if (!strncmp(mode_arg, "file:", 5)) { open_mode_file(mode_arg + 5); use_mode_file = 1; } else { rc = grok_mode_name(mode_arg, &mode_val); if (rc < 0) { fprintf(stderr, "error: invalid mode argument \"%s\"\n", mode_arg); exit(1); } } outf = fopen(outfname, "w"); if (!outf) { perror(outfname); exit(1); } state = amr_encoder_create(dtx, vad2); if (!state) { perror("amr_encoder_create()"); exit(1); } for (;;) { rc = read_input(inf, pcm, infname); if (!rc) break; if (use_mode_file) read_mode_file_line(&mode_val); amr_encode_frame(state, mode_val, pcm, &frame); amr_frame_to_tseq(&frame, cod_words); fwrite(cod_words, 2, AMR_COD_WORDS, outf); } fclose(outf); exit(0); }
