Merge 168093 - Don't wait endlessly for flushing the batched queries sent to the GPU driver during H/W decode We currently have a loop in the DXVA decoder on Windows 7 and above where we flush the queued D3D command bufers and wait for the operation to complete. This causes an infinite loop on certain multicore machines due to a bug in the IDirect3DQuery9::GetData call not returning the correct result. This seems to be a very old bug dating back to April 2008 http://us.generation-nt.com/idirect3dquery9-getdata-fails-return-ok-multi-core-cpus-help-26986872.html Fix for now is to have an upper limit of 10 iterations while we wait for the flush to complete. ld BUG=149139 R=apatrick Review URL: https://chromiumcodereview.appspot.com/11369229 TBR=ananta@chromium.org Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=168335
