Sometimes the resampler has enough space to store all the incoming samples without outputting anything. When this happens, gst_audio_resampler_get_out_frames() returns 0. In that case, the resampler should consume samples and just return. Otherwise, we get a segfault when gst_audio_resampler_resample() tries to resample into a NULL 'out' pointer.
