Hi,

we are using the dash muxer to create HLS/DASH files
from a live stream with AAC/H264.


this is working quite well.


sometimes we get this warning:

[dash @ 0x55d904d4ba80] Opening '/var/spool/live/bbbb/playlist.mpd.tmp' 
for writing
[dash @ 0x55d904d4ba80] Opening '/var/spool/live/bbbb/media_0.m3u8.tmp' 
for writing
[dash @ 0x55d904d4ba80] Opening '/var/spool/live/bbbb/media_1.m3u8.tmp'

audio. [ dts = 7938485, duration = 1015 ]
[mp4 @ 0x55d904d48fc0] Application provided duration: -43 / timestamp: 
7938485 is out of range for mov/mp4 format
[mp4 @ 0x55d904d48fc0] pts has no value
[dash @ 0x55d904d4ba80] Opening 
'/var/spool/live/bbbb/chunk-stream1-00019.m4s.tmp' for writing
audio. ok



the duration from application is 1015 and not -43:

    "Application provided duration"


where does the number -43 come from, is the duration
re-calculated again inside the muxer ?
