Failed to convert recorded video

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

I tried this solution but it doesn’t help:

Live Stream mp4 recording is corrupted due to additional track with AMF data? Wowza Streaming Engine

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.
