How can i solve this error ?



Why error occurs ?


-
| NGINX | FFMPEG not creating DASH manifests or chunks in the designated DIR |
7 avril 2020, par Mathew KnightHopefully someone can help here, I have a setup that takes two input RTMP streams from two separate machines into my server. From here I am trying to serve some MPEG DASH manifests and chunks to an experimental spatial audio/360 web (.js) player.



My issue is that while i can see the FFMPEG processes running and creating the Chunks the files themselves are not appearing in the specified folder and so the media player will not read the content.



Is there something obvious that i am not doing that is preventing these files being written ?



Any help with this would be amazing !!!

Codec AVOption tile-columns (Number of tile columns to use, log2) specified for output file #0 (http://localhost:1935/dash/video.mpd) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
