Good evening together,
I have another audio-sync question where we're out of ideas. We get an rtsp-Stream and mix it together with line-in over pulseaudio. This looks something like: ffmpeg \ -use_wallclock_as_timestamps 1 -fflags +genpts \ -max_delay 2000000 -thread_queue_size 1024 \ -i "rtsp://url" \ -use_wallclock_as_timestamps 1 -fflags +genpts \ -max_delay 2000000 -thread_queue_size 1024 \ -itsoffset <offset> \ -f pulse \ [...] So far so good. This _kind_ of works when fetching the rtsp stream directly. As soon as we route the rtsp stream through an nginx-rtmp loopback (live mode) beforehand, we get a delay of close to 5 s within the output. The rtmp-server itself does not cause a noticeable delay, I hence assume this to be a timestamp issue but my wisdom ends with the above written options. Any ideas anyone? Thanks a lot!
