    44The thing is that this side data will ''break'''''''' some players utilizing it. And they are clearly ''wrong'''''''' if one for example convert this source to 8 bit bt601.
    5 Usually I'm forced to use '''sidedata=delete''' and '''-map_metadata -1''' in order to get rid of unwanted side data and metadata, and this has fixed problems like this before. The side data in question is indeed presented as side data by ffmpeg and so one is lead to believe that they can also be removed by for example '''sidedata=delete'''. But they don't, and if there is no means to remove it then we have a problem.
