[dwzzhw]

When I load a gif image on my x86 device, the image can be displayed at first, but soon it will crash after a few loops, here is the crash backtrace:

besides gif image, an animated webp image may also cause a similar crash, the image is from fresco sample demo, https://www.gstatic.com/webp/animated/1.webp, and the backtrace looks like this：

Can anyone help us? Many thanks for your kind help!

Hi @dwzzhw, thanks for the detailed bug report!

Can you tell us on which exact device and Android version you are able to reproduce this?

[massimocarli]

Hi @dwzzhw,
can you tell us if the problem persists also with the last update of libwebp to version 0.5.2 we have done in release 1.0.1?
Thanks

[dwzzhw]

hi @lambdapioneer, I reproduce this issue on Lenovo K900, with android 4.3 inside

[dwzzhw]

hi @massimocarli, yes, this problem still persists with libwebp version 0.5.2

We've significantly changed animated image rendering with more recent Fresco versions, so I'll close this for now. If this is still an issue, please let us know.
