From 2cff7a2ba7d516db7f1f0c376bddd2852abfc52c Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Wed, 18 Apr 2018 23:25:25 +0200 Subject: [PATCH] input/wav: Put internal buffer on the heap instead of the stack. Increasing the buffer/chunk size could cause issues when trying to put large arrays on the stack. --- src/input/wav.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/src/input/wav.c b/src/input/wav.c index a1751243..e5ab0891 100644 --- a/src/input/wav.c +++ b/src/input/wav.c @@ -189,15 +189,15 @@ static void send_chunk(const struct sr_input *in, int offset, int num_samples) struct sr_analog_meaning meaning; struct sr_analog_spec spec; struct context *inc; - float fdata[CHUNK_SIZE]; + float *fdata; int total_samples, samplenum; char *s, *d; inc = in->priv; s = in->buf->str + offset; + fdata = g_malloc0(CHUNK_SIZE * sizeof(float)); d = (char *)fdata; - memset(fdata, 0, CHUNK_SIZE * sizeof(float)); total_samples = num_samples * inc->num_channels; for (samplenum = 0; samplenum < total_samples; samplenum++) { if (inc->fmt_code == WAVE_FORMAT_PCM_) { @@ -238,6 +238,7 @@ static void send_chunk(const struct sr_input *in, int offset, int num_samples) analog.meaning->mqflags = 0; analog.meaning->unit = 0; sr_session_send(in->sdi, &packet); + g_free(fdata); } static int process_buffer(struct sr_input *in)
