This bug is caused by using ‘lhu’ to load two byte date on bigendian environment. Has been fixed in V4. Please help to merge them. BTW, I found another failed case ‘fate-sub2video_time_limited’ when testing origin/master with cross compiler mips-linux-gnu-gcc-8 on debian10-x64 and run fate with qemu-mips. I will try to analyze it later. My configuration: --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-pthreads --disable-iconv --disable-mipsfpu TEST sub2video_time_limited --- src/tests/ref/fate/sub2video_time_limited 2021-04-10 11:53:37.661350105 +0800 +++ tests/data/fate/sub2video_time_limited 2021-04-12 23:18:29.355527385 +0800 @@ -4,5 +4,5 @@ #dimensions 0: 1920x1080 #sar 0: 0/1 0, 2, 2, 1, 8294400, 0x00000000 -0, 2, 2, 1, 8294400, 0xa87c518f -0, 10, 10, 1, 8294400, 0xa87c518f +0, 2, 2, 1, 8294400, 0xea5a518f +0, 10, 10, 1, 8294400, 0xea5a518f Test sub2video_time_limited failed.
