Race condition between vpx_codec_enc_init and vpx_codec_encode #189

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
A simple use of libvpx in Chromium is causing race conditions:

http://src.chromium.org/viewvc/chrome/trunk/src/remoting/base/encoder_vp8.cc?vie
w=markup

Valgrind detected that there's race conditions between vpx_codec_enc_init and 
vpx_codec_encode. Here's a bug filed in Chromium that shows the stack trace.

James,

Are there any tests for VP8 besides test-vectors?

I'd like to try them out under Valgrind and ThreadSanitizer but I'm not sure 
where to start

Thank you,
Timur Iskhodzhanov,
