From e0d5ee00451630c83ba1693939aa6c923f41b727 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Wed, 11 Nov 2009 20:18:39 +0100 Subject: decoder/flac: calculate time stamp from current frame Don't update a float timestamp, this will make imprecisions add up after a while. We already have the number of the current frame, let's just calculate the float timestamp from that for every decoder_data() command. For this, we need to add the attribute "first_frame", for CUE sheet songs. --- src/decoder/flac_plugin.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) (limited to 'src/decoder/flac_plugin.c') diff --git a/src/decoder/flac_plugin.c b/src/decoder/flac_plugin.c index afc134077..cbb95bf45 100644 --- a/src/decoder/flac_plugin.c +++ b/src/decoder/flac_plugin.c @@ -191,14 +191,9 @@ static FLAC__StreamDecoderWriteStatus flac_write_cb(const FLAC__StreamDecoder *dec, const FLAC__Frame *frame, const FLAC__int32 *const buf[], void *vdata) { - FLAC__uint32 samples = frame->header.blocksize; struct flac_data *data = (struct flac_data *) vdata; - float timeChange; FLAC__uint64 nbytes = 0; - timeChange = ((float)samples) / frame->header.sample_rate; - data->time += timeChange; - if (FLAC__stream_decoder_get_decode_position(dec, &nbytes)) { if (data->position > 0 && nbytes > data->position) { nbytes -= data->position; @@ -431,6 +426,8 @@ flac_decoder_loop(struct flac_data *data, FLAC__StreamDecoder *flac_dec, struct decoder *decoder = data->decoder; enum decoder_command cmd; + data->first_frame = t_start; + while (true) { if (data->tag != NULL && !tag_is_empty(data->tag)) { cmd = decoder_tag(data->decoder, data->input_stream, @@ -448,8 +445,6 @@ flac_decoder_loop(struct flac_data *data, FLAC__StreamDecoder *flac_dec, (t_end == 0 || seek_sample <= t_end) && FLAC__stream_decoder_seek_absolute(flac_dec, seek_sample)) { data->next_frame = seek_sample; - data->time = (float)(seek_sample - t_start) / - data->audio_format.sample_rate; data->position = 0; decoder_command_finished(decoder); } else -- cgit v1.2.3
