/* * gsmefr-etsi-enc is a test program for our EFR encoder: it reads raw * 16-bit PCM (matching ETSI's *.inp) as input and writes ETSI's *.cod * format as output, allowing our encoder to be tested with ETSI's * official test sequences. * * ETSI input and output files are read and written in LE byte order, * matching the official test sequences in ts_100725v050200p0.zip. */ #include <stdio.h> #include <stdint.h> #include <stdlib.h> #include <string.h> #include <strings.h> #include <unistd.h> #include "../libgsmefr/gsm_efr.h" main(argc, argv) char **argv; { char *infname, *outfname; FILE *inf, *outf; struct EFR_encoder_state *state; int16_t pcm[160]; uint8_t frame[EFR_RTP_FRAME_LEN], bits[250]; int opt, dtx = 0, rc, sp, vad, big_endian = 0; extern int optind; while ((opt = getopt(argc, argv, "bd")) != EOF) { switch (opt) { case 'b': big_endian = 1; continue; case 'd': dtx = 1; continue; default: usage: fprintf(stderr, "usage: %s [-b] [-d] input.inp output.cod\n", argv[0]); exit(1); } } if (argc != optind + 2) goto usage; infname = argv[optind]; outfname = argv[optind+1]; inf = fopen(infname, "r"); if (!inf) { perror(infname); exit(1); } outf = fopen(outfname, "w"); if (!outf) { perror(outfname); exit(1); } state = EFR_encoder_create(dtx); if (!state) { perror("EFR_encoder_create()"); exit(1); } for (;;) { rc = read_input(inf, pcm, infname, big_endian); if (!rc) break; EFR_encode_frame(state, pcm, frame, &sp, &vad); frame2bits(frame, bits); bits[248] = vad; bits[249] = sp; emit_output(outf, bits + 4, 246, big_endian); } fclose(outf); exit(0); }
