[FFmpeg-devel] [PATCH] avcodec/exr

I uploaded rle_grayscale_noffset.exr using the videolan file uploader.
The rle_grayscale_nooffset.exr image was modified from https://trac.ffmpeg.org/raw-attachment/ticket/5621/rle_grayscale.exr by zeroing out the line offset table. The modified file is viewable with Adobe Photoshop but results in a blank image when processed by ffmpeg.
Let me know if you need additional test images.
