I'm trying to overlay a v4l2 input on the mjpeg stream of an android IP camera. The first few seconds are alright, but the overlay slowly lags behind more and more, and starts dropping frames. I also get the following warning: > > Thread message queue blocking; consider raising the

[FFmpeg-user] 7.1 wave filter complex amerge issue

Trying to remap channels in a 7.1 Wave file, but that gives me a strange error. (I’ve reduced my lines to the most simple to reproduce.) When I use the same input file, but do a 5.1 remap it works as expected: /Applications/ffmpeg -i /Volumes/Data/LC_testfiles/8chan.wav -filter_complex
