* ./src/audio_output/output.c: reverted my previous aout_OutputNextBuffer
prototype change; it looks like we won't need it after all. * ./src/audio_output/output.c: if audio output is too slow, but we know there is no next packet, then we play it anyway. Rationale behind this is: better play a slightly wrongly dated packet than play silence, because it might be wrongly dated but there are chances it won't break audio continuity. * ./modules/audio_output/sdl.c: workaround for SDL's crap audio output system (callback gets called at random times, and no way to know the latency of the samples being played). Audio output is now rather good here, but please give feedback. * ./modules/audio_output/oss.c: we delay a bit before asking for a new buffer to avoid starvation.
