MarsSeed [1] filed a deletion request for ffmpeg-obs [2]: Arch extra repo carries obs-studio and ffmpeg, and the two seem to work just fine with each other. OBS studio carries two very minimal, one-line patches for ffmpeg. One is a crude hack for flvdec (FLV decoder), to handle 'TYPE_UNKNOWN'. FLV is practically a dead format (Flash Video). This patch makes FFMPEG accept FLV files with malformed/nonexistent header, which is not really something that people would need in general. The other is for AOMenc, minimally changing the default quality preset - which is configurable via command line option anyway. Hardy any of these changes are essential. Please kindly delete this package, it doesn't seem worth the trouble to keep it. In case there is a bug with OBS Studio and its use of FFMPEG, please file a bug report in Arch bug tracking system and preferably with upstream as well (OBS and/or FFMPEG, whichever is relevant). This is what the AUR submission guidelines is asking for as well, instead of creating duplicates of repo packages on AUR.
