undefined symbol: avcodec_receive_frame

[Trunpm]

Hi, when i run the: lintel_test --filename --width --height --frame-nums --should-seek, an error like: ImportError: ./_lintel.cpython-35m-x86_64-linux-gnu.so: undefined symbol: avcodec_receive_frame arise. I am try hard to solve this problem using ldd: LD_DEBUG=libs ldd , the line like libavcodec.so.57 not found in my terminal window, I still try make the LIBRARY_PATH and LD_LIBRARY_PATH all the same when using pip install. But the error still exist. Could you give me some tips or solutions? Thanks!

Hi, have you installed FFmpeg on your system? If so, how, via package manager, or from source? The error you are getting is either because you haven't installed FFmpeg, or because your FFmpeg is too old (and doesn't have the avcodec_receive_frame symbol).
