From: Arun Raghavan <[email protected]> It is possible that we get a zero-length memchunk to work with. Specifically, this happens the resampler (which is called before the lfe-filter) consumes all the input data, but does not (yet) produce any output data.
Reproduced using: pulseaudio --resample-method=soxr-mq pactl load-module module-null-sink sink_name=lfe_test channels=3 channel_map=front-left,front-right,lfe paplay --raw /dev/zero --rate=48000 -d lfe_test Thanks to the original reporter for the backtrace: Bug: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1496577 --- src/pulsecore/filter/lfe-filter.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/pulsecore/filter/lfe-filter.c b/src/pulsecore/filter/lfe-filter.c index 8c79b55..5f5ace2 100644 --- a/src/pulsecore/filter/lfe-filter.c +++ b/src/pulsecore/filter/lfe-filter.c @@ -113,7 +113,7 @@ pa_memchunk * pa_lfe_filter_process(pa_lfe_filter_t *f, pa_memchunk *buf) { struct saved_state *s, *s2; void *data; - if (!f->active) + if (!f->active || !buf->length) return buf; /* Remove old states (FIXME: we could do better than searching the entire array here?) */ -- 2.4.3 _______________________________________________ pulseaudio-discuss mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
