vmaf compute with x265 integrated libvmaf segment fault error #247

Closed coolfat closed 5 years ago

coolfat commented 5 years ago

The command is follows: ./x265 --input src.yuv --fps 25.0 --input-res 720x1280 --csv csv.log --crf 18.0 --recon rec.yuv -o dst-src.265

Env: linux system gcc version: gcc.4.8.2

I check the backtrance in gdb: 0x00007ffff6c1e3f7 in raise () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 (gdb) bt 0 0x00007ffff6c1e3f7 in raise () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 1 0x00007ffff6c1f7d8 in abort () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 2 0x00007ffff6c5c554 in __libc_message () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 3 0x00007ffff6c61dbe in malloc_printerr () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 4 0x00007ffff6c64a72 in _int_realloc () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 5 0x00007ffff6c65929 in realloc () from /opt/compiler/gcc-4.8.2/lib/libc.so.6 6 0x000000000062cb91 in readline (input=0x7fffe1f4b1f0)

what is the problem?

li-zhi commented 5 years ago

Did you point to the right model file, for example: model/vmaf_v0.6.1.pkl?

Yes, the model file is correct. I have resolved the problem. I use a mutex_lock when x265 call compute_vmaf() api. ![Uploading 图片.png…]()

Thanks.
