Anyone? Meanwhile I've done the muxing with mkvmerge from MKVToolNix <
https://mkvtoolnix.download/> package without any problem and muxed other
movies with FFmpeg successfully.
Could you give us the full command line and output from ffmpeg?
Hello,
Sure, the steps to reproduce were the following (i.e. the same that was
done here <http://ffmpeg.gusari.org/viewtopic.php?f=11&t=2713>):
1. Download Sintel movie from https://durian.blender.org/download/ :
ffmpeg -i Sintel.2010.1080p.mkv

But strange enough and as clear from the output above I do not have the
warning now. It's the same if I re-encode the audio to AAC for example
(i.e. run ffmpeg -i Sintel.2010.1080p.mkv -vn -map 0:1 -map_chapters -1
-c:a aac Sintel.2010.1080p.audio.mkv in step 2 instead). I'll try again
with the streams that first caused this warning to appear for me and
write back later.
What is the general reason for warning "Starting new cluster due to
timestamp" to appear anyway?
