            avformat/mpegts: parse large PMTs with multiple tables
    

    
            In 9152c1e4955, the mpegts parser was taught how to parse
    
            PMT sections which contained multiple tables. That commit
    
            fixed parsing of PMT packets from some cable providers,
    
            which included a special SCTE table (0xc0) before the

    avfilter/vf_libplacebo : update metadata stripping logic

    Switches to av_frame_side_data_remove_by_props(), covering a number of
    
cases that we previously ignored. Additionally, stop stripping metadata
    
when merely changing colorspace or color range, since these do not
    
affect the actual color volume of the image data, only the encoding.

    avformat/dashdec : Cosmetics

    1. Perform the necessary reindentations after the last few commits.
    
2. Adapt switches to the ordinary indentation style.
    
3. Now that the effective lifetimes of the variables containing
    
the freshly allocated strings used when parsing the representation
    
are disjoint, the variables can be replaced by a single variable.
    
Doing so has the advantage of making it more clear that these are
    
throwaway variables, hence it has been done.
