From e7a515c8b11c643332406d60a13ab1fe06d2b226 Mon Sep 17 00:00:00 2001 From: Tim Phipps Date: Sun, 21 Mar 2010 18:21:47 +0100 Subject: Add support for MixRamp tags Adds mixrampdb and mixrampdelay commands. Reads MIXRAP_START and MIXRAMP_END tags from FLAC files and overlaps instead of crossfading. --- src/decoder/mad_decoder_plugin.c | 47 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) (limited to 'src/decoder/mad_decoder_plugin.c') diff --git a/src/decoder/mad_decoder_plugin.c b/src/decoder/mad_decoder_plugin.c index 379cb9b8a..6f6ee8fa4 100644 --- a/src/decoder/mad_decoder_plugin.c +++ b/src/decoder/mad_decoder_plugin.c @@ -347,6 +347,47 @@ parse_id3_replay_gain_info(struct replay_gain_info *replay_gain_info, } #endif +#ifdef HAVE_ID3TAG +static bool +parse_id3_mixramp(char **mixramp_start, char **mixramp_end, + struct id3_tag *tag) +{ + int i; + char *key; + char *value; + struct id3_frame *frame; + bool found = false; + + *mixramp_start = NULL; + *mixramp_end = NULL; + + for (i = 0; (frame = id3_tag_findframe(tag, "TXXX", i)); i++) { + if (frame->nfields < 3) + continue; + + key = (char *) + id3_ucs4_latin1duplicate(id3_field_getstring + (&frame->fields[1])); + value = (char *) + id3_ucs4_latin1duplicate(id3_field_getstring + (&frame->fields[2])); + + if (g_ascii_strcasecmp(key, "mixramp_start") == 0) { + *mixramp_start = strdup(value); + found = true; + } else if (g_ascii_strcasecmp(key, "mixramp_end") == 0) { + *mixramp_end = strdup(value); + found = true; + } + + free(key); + free(value); + } + + return found; +} +#endif + static void mp3_parse_id3(struct mp3_data *data, size_t tagsize, struct tag **mpd_tag) { @@ -403,10 +444,16 @@ static void mp3_parse_id3(struct mp3_data *data, size_t tagsize, if (data->decoder != NULL) { struct replay_gain_info rgi; + char *mixramp_start; + char *mixramp_end; if (parse_id3_replay_gain_info(&rgi, id3_tag)) { decoder_replay_gain(data->decoder, &rgi); data->found_replay_gain = true; } + if (parse_id3_mixramp(&mixramp_start, &mixramp_end, id3_tag)) { + g_debug("setting mixramp_tags"); + decoder_mixramp(data->decoder, mixramp_start, mixramp_end); + } } id3_tag_delete(id3_tag); -- cgit v1.2.3
