Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Is the issue also reproducible if you output to mp4 or mov?
Is the issue also reproducible with the x264 encoder?

[Alfred]

if I change the output from DASH to MP4 then the warning is NOT printed.

the warning is coming from the audio stream, possibly because the RTMP protocol
is truncating the timestamps to 1/1000 (milliseconds).
