[09:42] yury cpearce: I'm trying to run fmp4/mse playback locally [09:42] yury getting assert at http://mxr.mozilla.org/mozilla-central/source/content/media/fmp4/MP4Reader.cpp#111 [09:43] yury does it need non-virtual window 8.1? [09:43] -->| ekr (ekr@moz-FAC44BDF.hfc.comcastbusiness.net) has joined #media [09:43] =-= Mode #media +ao ekr ekr by ChanServ [09:45] cpearce yury: we need that if we're going to get DXVA acceleration. we should do two things: [09:45] cpearce 1. provide a decoder owner so that we can get the layer manager so that we can get dxva, and [09:45] cpearce 2. not exit with failure if we can't. we can just fallback to software. [09:46] |<-- mt has left moznet (Quit: Leaving.) [09:46] cpearce yury: so to get unblocked, just comment out that block. [09:46] yury cool [09:46] cpearce yury: I'll file a bug to address those. This bug addresses (2) above. If MP4Reader::Init() can't find a decoder owner, we can just assume LAYERS_NONE. This means we won't get hardware accelerated decoding on Windows, but too bad.
Make MP4Reader::Init() assume mLayersBackendType=LAYERS_NONE if it doesn't have a decoder owner. r=kinetik This ensures that if the MP4Reader fails to get a decoder owner, we don't abort the media load, but instead we will assume that we don't have an advanced layers backend, and so fallback to software decoding on Windows.

With this patch, we play the "car" MP4 test case at http://dash-mse-test.appspot.com perfectly on Windows. :)
