"+" means that the flag should be set (no effect for flags that are set by default or by the application) , "-" that the flag should be removed (no effect if the flag is not set by default or by the application) > There is no explanation on this at: > https://www.ffmpeg.org/ffmpeg-codecs.html#Codec-Options True. > - How to determine, if global codec options (e.g. "-level") are valid > for audio, video or both. You cannot because it is codec-specific (so if you know the codec you are using, you know if it - or its implementation - supports levels).
