why the test successed randomly? do you have encountered this situation? why i suggest to update os is because i achieved more success probability on build-010. by the way, all test successed 100% exactly on loongson3b machine. so, if the random fail is not acceptable and you assure there's no relationship with the fate-test itself, i will abort this patch and rewrite. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
