Hello, Michael Can fate-sub2video_time_limited pass on your mips qemu before? I doubt if it’s qemu’s problem. I build latest master branch without my patch set and disabled all asm code, then run fate test in qemu-mips which download from debian10 repository. ../ffmpeg/configure --samples=../../fate-suite/ --target-exec='/usr/bin/qemu-mips -cpu 74Kf -L /usr/mips-linux-gnu/' --cross-prefix=/usr/mips-linux-gnu/bin/ --cc=mips-linux-gnu-gcc-8 --arch=mips --target-os=linux --optflags='-O3 -g -static' --extra-ldflags=-static --enable-cross-compile --enable-static --enable-gpl --disable-mipsfpu --disable-iconv --disable-pthreads --disable-asm --cpu=74kf make fate-sub2video_time_limited _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
