[FFmpeg-user] ffplay AC3 playback latency
Hello, I have a data source that is providing an AC3 bitstream in real time via an external interface. I am piping this into ffplay, which I’m using to decode it and play it back through my soundcard for live listening. This bitstream is coming from a video game console, so it’s important to have as little latency as possible. I’m running Linux with Pulseaudio. I have configured Pulseaudio such that my sound card (sink) has a fixed 8 millisecond latency, and the incoming bitstream coming from the external interface has under 2 milliseconds of latency. The command I’m using is “ffplay -fflags nobuffer -”. Here’s the thing: normally, this works great, with no significant latency. If I run “pactl list sink-inputs”, I see about 20 milliseconds of latency, and the sink itself reports about 8 milliseconds. However, sometimes the latency is large - like 400 milliseconds. I have no idea why this happens. Killing and restarting ffplay fixes it though. As a test, I modified SDL_AUDIO_MAX_CALLBACKS_PER_SEC to a high value such that the resulting SDL buffer size is always 512 (the minimum). This didn’t really help. Any ideas where this extra buffering is coming from and how to eliminate it? Also keep in mind that the soundcard and data source are on two separate clock domains, so I guess I’ll need ffplay to continue performing asynchronous sample rate conversion (assuming it does that already?).

They ought to update themselves Do you need to run on a hosting platform at all? ffmpeg runs on a lot of systems; most people run it on their own local boxes. If you can copy files to/from HostUpon, you should be able to copy over a static build and use that- it doesn't require any special permissions to run. I don't know of -any- hosting platforms that explicitly provide ffmpeg, but I expect any that sell linux would have it.
