This change applies only for automatic proxy building, when strip is added to timeline. Manual building process is not affected. Don't build proxy file if movie is already fast enough to seek. To determine seek performance, check if whole GOP can be decoded in 100 milliseconds. To consider some variation in GOP size, large number of packets are read, assuming that each packet will produce 1 frame. While this is not technically correct, it does give quite accurate estimate of maximum GOP size. This test will ensure consistent performance on wide array of machines. Check should be done in order of few milliseconds. Reviewed By: sergey Differential Revision: https://developer.blender.org/D11671
