gmail.com: Regression on mipsel introduced in dea3e89983f299b3325898fa5b9474be258553b2
https://bugs.chromium.org/p/webp/issues/detail?id=558What steps will reproduce the problem?
1. cwebp kollada_noalpha.png -lossless -o kollada_noalpha.webp
2. dwebp kollada_noalpha.webp
What is the expected output? What do you see instead?
Expected output:
Saving file 'kollada_noalpha.webp'
File: /home/sramacher/kollada_noalpha.png
Dimension: 436 x 160
Output: 36050 bytes (4.13 bpp)
Lossless-ARGB compressed size: 36050 bytes
* Header size: 671 bytes, image data size: 35354
* Precision Bits: histogram=3 transform=3 cache=1
File kollada_noalpha.webp can be decoded (dimensions: 436 x 160 . Format: lossless).
Nothing written; use -o flag to save the result as e.g. PNG.
Actual output:
Saving file 'kollada_noalpha.webp'
File: /home/sramacher/kollada_noalpha.png
Dimension: 436 x 160
Output: 35454 bytes (4.07 bpp)
Lossless-ARGB compressed size: 35454 bytes
* Header size: 676 bytes, image data size: 34753
* Precision Bits: histogram=3 transform=3 cache=1
Decoding of kollada_noalpha.webp failed.
Status: 3(BITSTREAM_ERROR)
What version of the product are you using? On what operating system?
libwebp 1.2.1 on current Debian unstable. I have also reproduced the issue with the current HEAD of the git repository.
Please provide any additional information below.
I'm forwarding a bug from Debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1006009. During the transition to libwebp 1.2.1 we noticed a regression on mipsel. A git bisect run suggests that this regression was introduced in dea3e89983f299b3325898fa5b9474be258553b2. The input and output file from the bug reports are attached.
