libvpx crashed on iphone/ipad #773

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,
I encoded a video stream on my iphone/ipad with libvpx and it crashed at 
sad16_neon.asm.s(function vp8_sad16x16_neon).

Then i built libvpx with parameter --disable-neon. it could be work but cost so 
much cpu resource.

Both trunk and v1.3.0 have this problem. There are some errors when building 
v1.2.0 and below with iOSSDK 7.1, so I cannot test it..

Can you please share more information about the crash? Do have have a stack 
trace? Does it happen all the time or intermittently? We recently made some 
changes which fixed how the neon registers were used. If you could try a 
version from within the last ~week I would appreciated it.

I believe this was fixed by saving the registers. Please reopen if you still 
see this with current HEAD.
