 Summary of the bug: I've created an image sequence by converting PNG
 images to EXR using ImageMagick 7.1.1. If I compress them using PIZ,
 ffmpeg 5.1.4 can read them well and convert the sequence to a video
 format. If I compress them using DWAB, I get [exr @ 0x1a80240]
 decode_block() failed. errors. I tried ffmpeg 6.1 with same results.
 It seemed to me that ffmpeg 5.1.4 was able to decode DWAB compressed EXR
 files. Am I mistaken?

 How to reproduce:
 {{{
 % ffmpeg -threads 24 -thread_queue_size 4096  -r 24  -f image2 -i
 Images/Electra_24fps/Electra-%06d.exr -pix_fmt yuv422p12 -c:v ffv1 -level
 3 -slices 24 -context 1 -coder 1 -slicecrc 1  -an -r 24
 -video_track_timescale 24  Electra-MASTER_FFV1-24fps.mkv

 ffmpeg version 5.1.4, but also with 6.1
 built on Slackware-current (self-built, not official)
 }}}

 Provided sample image and report.
