Question by ahmed alaa · Sep 07, 2017 at 02:05 AM · wowza streaming enginelive stream delay in player

RTMP playback delay on vlc increases overtime

please help ...

i'm trying wowza to send a RTSP stream from an android device to other LAN clients

i'm using VLC to play the RTMP stream as a client

when starting a playback ... the delay is < 1 second and that's really really great

but overtime the delay keeps increasing ... sometimes when i leave the streaming ON .. for about an hour or more ...
the delay reaches 5-7 seconds !!!

but when i stop the VLC playback and start it immediately the delay return back to it's first state (< 1 second)

i almost tried everything

- i tried setting cache to low value in VLC but that decreases the instant delay ... not that accumulating dela

- i tried to decrease the bitrate of encoding .... i even set it to 10 kbps !!!
i knew that the quality would get so bad but i wanted to test the theory that it's just a
bitrate vs bandwidth issue ... also didn't work .. it's barely the same

- i tried setting the stream type to (live-lowlatency) in the conf of live application (application.xml)

- i tried a tip that was mentioned before in another question .. by adding those properties in the xml too

<Property>

<Name>instantOn</Name> <Value>true</Value> <Type>Boolean</Type>

</Property>

<Property>

<Name>instantOnBufferTime</Name> <Value>3000</Value> <Type>Integer</Type>

</Property>

but all leads to the same issue .. i can't get rid of that accumulating delay please if anyone can help
