/* * gsmfr-encode-r is just like gsmfr-encode, but reads the source * linear PCM data to be encoded from a raw BE file ("robe") * instead of WAV. * * Addendum: gsmfr-encode-r -h flag enables the later-spec feature * of encoder homing. This option is not replicated in WAV-reading * gsmfr-encode because it is deemed to be of no use with WAV. */ #include <stdio.h> #include <stdint.h> #include <stdlib.h> #include <string.h> #include <strings.h> #include "../libgsmfr2/tw_gsmfr.h" #include "../libtest/roberead.h" main(argc, argv) char **argv; { char *infname, *outfname; FILE *inf, *binf; struct gsmfr_0610_state *enc_state; int16_t pcm[160]; uint8_t frame[33]; int homing, rc; if (argc == 3 && argv[1][0] != '-') { homing = 0; infname = argv[1]; outfname = argv[2]; } else if (argc == 4 && !strcmp(argv[1], "-h")) { homing = 1; infname = argv[2]; outfname = argv[3]; } else { fprintf(stderr, "usage: %s [-h] input.robe output.gsm\n", argv[0]); exit(1); } inf = fopen(infname, "r"); if (!inf) { perror(infname); exit(1); } binf = fopen(outfname, "w"); if (!binf) { perror(outfname); exit(1); } enc_state = gsmfr_0610_create(); if (!enc_state) { fprintf(stderr, "gsmfr_0610_create() failed!\n"); exit(1); } for (;;) { rc = robe_get_pcm_block(inf, pcm); if (!rc) break; gsmfr_0610_encode_frame(enc_state, pcm, frame); if (homing) gsmfr_0610_encoder_homing(enc_state, pcm); fwrite(frame, 1, sizeof frame, binf); } fclose(binf); exit(0); }
