Bug 224232 – [GTK][WPE] Avif decoder build broken

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Philippe Normand]

I´m about to deploy a SDK update shipping avif 0.9.0, the build fails but as this feature is currently disabled by default I think it´s fine ;)

Doesn't we need to check if incoming data is compatible to avif or avifs here, first?

I don´t think so. The examples I´ve found call avifDecoderSetIOMemory() and then avifDecoderParse() which internally calls avifParse() which should hopefully handle parse errors. Do you think something additional is needed?
