 Summary of the bug:
 I've encountered multiple RPL (Acorn Replay Video) video files on old RISC
 OS CDs that ffmpeg doesn't support at all.

 Sample file attached and more here:
 https://telparia.com/fileFormatSamples/video/acornReplayVideo/ (bluegreen,
 butterfly3, chimes, ducks2, parrot, voyager)

 How to reproduce:
 {{{
 % ffmpeg -i parrot out.mp4
 ffmpeg version 4.4.1 Copyright (c) 2000-2021 the FFmpeg developers
   built with gcc 11.2.1 (Gentoo 11.2.1_p20211127 p0) 20211127
 [rpl @ 0x17dc7c0] Video format [7][0][0][0] 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.
 [rpl @ 0x17dc7c0] Don't know how to split frames for video format
 [7][0][0][0]. Video stream will be broken!
 [rpl @ 0x17dc7c0] Could not find codec parameters for stream 0 (Video:
 none ([7][0][0][0] / 0x0007), none, 160x128): unknown codec
 }}}

 Format of RPL files appears to be here: https://multimedia.cx/AE7doc.txt

 Any chance support for compression type #7 could be added?
