Thanks for your review James. Would "Quality/spatial/multiview scalability" be better or do you have some other suggestion? The message is put in a template by avpriv_report_missing_feature, e.g. [vvc @ 0x618000003c80] Multilayer is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. so the string passed to avpriv_report_missing_feature must be a noun. -- Frank _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
