Hi, I noticed a strange behavior with the recorded video from the WebRTC stream. Once the stream has been terminated after 1-3 seconds, the video fails to convert using FFmpeg (checked with the latest version). If the video is about 10 seconds long, the conversion works just fine. Note: the input videos can be played using e.g. QuickTime Player, VLC ![Default (bash) 2020-11-06 11-53-14](https://us1.discourse-cdn.com/flex002/uploads/wowza1/original/1X/d59e5bb437658d5f4cde63f111e7e1826c731912.png) I tried this solution but it doesn’t help: > [@Live Stream mp4 recording is corrupted due to additional track with AMF data?](http://community.wowza.com/t/live-stream-mp4-recording-is-corrupted-due-to-additional-track-with-amf-data/46925/2): > > Hi Benjamin, This was handled in the created support ticket (168093). I see that you reported finding a solution: The resolution was to change a couple settings for Streams in the Manager. I turned off MP4WriteData/MP4WriteMetaData and that fixed the issue with recordings.

Sorry you never got a response, these types of webrtc issues can be tricky to diagnose in the forums and usually require a support ticket for debugging. Especially so we can try to replicate it using ffmpeg. Hope it’s been resolved. If not please submit a ticket and a wowza engineer can take a closer look for you. > **[Open a Support Ticket](https://www.wowza.com/support/open-ticket)** > > Open a Wowza suppor ticket so our technical support engineers worldwide can help you succeed with your Wowza software and services.
