Hi all,

I’d like to ask if you have following/similar problem and ideally also solution. My setup is following:

1. capture with BM H.264 Pro Recorder

2. streaming to wowza with MXLight/FFMPEG and RTMP

The basic problem is that after some time of continuous streaming (usually around 20 hrs but can be also fewer), FFMPEG spontaneously exits with following message:

[output stream 0:1 @ 025af9c0] EOF on sink link output stream 0:1:default.

No more output streams to write to, finishing.

Streaming command is:

“C:\MXLight\utils\ffmpeg.exe” -rtbufsize 67108864 -re -f mpegts -c:v:0 h264 -c:a:1 aac -analyzeduration 500000 -fps

probesize 6 -i tcp://127.0.0.1:41116 -c:v copy -copyts -r 25 -af “volume=0dB” -c:a libvo\_aacenc -ac 2 -ar 44100 -b:a 9

6k -bufsize 2000k -f flv -

This causes MXLight process to freeze (I am trying to solve this with its author as well).

Thanks a lot,

Martin

Difficult to say, but you may also want to check the Wowza logs at around the same time to see if any relevant event was captured, [wowza-install-dir]/logs/wowzastreamingengine\_access.log. If you feel that it may point to a Wowza issue then please do raise a ticket with support@wowza.com (quote this forum post) and we’ll be in touch very quickly.

Maybe unrelated, but I did read elsewhere that some people were having more luck with the [libav](https://libav.org/) fork of ffmpeg in combination with [Black Magic encoders](http://forum.blackmagicdesign.com/viewtopic.php?f=12&t=13696). Certainly something to also keep an eye on even if it ends up not related to the current issue you’re experiencing.
