LZ4 Decompression Missing or Outdated? #415
Comments
To use lz4 compression in grub4dos, you must add the -- content size parameter |
I already added --content-size 🤔 In old version of lz4 (compiled years back on this link), decoding works normal These are 2 current versions LZ4.exe (by original author) edit: Tried both versions, same error Error 25: (http://grub4dos.chenall.net/e/25) with VHD, i see counter [xxxxM/xxxxxM] but for LZ4, i don't see any mapping counter |
Something is very wrong or "un-optimized" in UEFI version of grub4dos. Decoding time is double of Copy speed. image compressed with the old version of lz4.exe is read once and then, possibly read again by grub4dos (where read counter shows up afterwards) |
Use lz4_win64_v1_9_4.zip, use Lz4 -9 --content-size test.img test.lz4, no problem. map --mem /test.lz4 (hd) OK! |
Same error . I used (lz4_win64_v1_9_4.zip) lz4 -1 --content-size 10x64.vhd 10x64.lz4

I understand, you have compressed vhd. It seems that vhd cannot be compressed anymore. He can be dynamic and can check scores. |
If I use Old version of LZ4 by Chenall (http://dl.grub4dos.chenall.net/lz4_xp.7z) then, grub4dos can decompress but take double time! maybe author updated decompression code of new version? I use only Fix size VHD (not dynamic) |
Images compressed with current version of LZ4 compression (1.9.4) fails to decode in Grub4Dos UEFI
