      skiptags: properly conceal ID3/APE tags (fixes #18501) · 2c34ea75
      Rémi Denis-Courmont authored
      As most demuxers cannot handle tags at the beginning of their input
      streams, the demuxer code has automatically skipped them for a long
      time.
      
      Unfortunately, a number of demuxers also assume that the initial stream
      byte offset is zero (while some others seem to assume zero in some paths
      and not in others). This seems like a reasonable assumption. And even if
      it were not, fixing all affected stream filters and demuxers to perform
      only relative seeking seems impractical and unpalatable.
      
      This stream filter shifts the stream byte offset so that the tags are
      entirely invisible, and the demuxer can assume the start is at offset 0.
      
      Of couse, the tags must still be accessible to the meta extraction
      engine(s). The TagLib plugin uses "low-level" vlc_access_NewMRL() so it
      is not subject to stream filters, and not affected by this change.
      (This change does however remove tags from "demuxdump".)
      
      NOTE: On the one hand, this also enables demuxing a file format with
      embedded absolute file offsets, if the tags were prepended after muxing.
      On the other hand, it conversely breaks demuxing such a file format if
      the tags are added during muxing. As far as I know, tags are normally
      appended rather than prepended to avoid this ambiguity.
