  • FFmpeg file not found exception, No such file or directory

    16 avril 2020, par Sagar

    I am getting the No such file or directory exception on video trimming.

    



    video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

    



    file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

    



    and ffmpeg searching for only Fast in/storage/emulated/0/Pictures/Instagram/Fast: No such file or directory


    



    I have found the issue, it is causing due to the file name having spaces in between them you can check in the above mentioned path and in exception.

    



    after changing the file name its working but the changing name of every file from the device it's not the right way so how can I solve this exception

  • OpenCV 3.0.0 make error with FFMPEG

    24 mars 2016, par Ujjwal Aryan

    I have been using OpenCV for a while. However I have recently changed my system to a cluster where I do not have any admin permission. The problem is like this :

    In my home folder, I installed FFMPEG (latest stable version available on ffmpeg site). I installed it in $HOME, and so in $HOME/lib there are the library files installed. For more information I compiled FFMPEG with following options :

    ./configure --prefix=$HOME --enable-shared --enable-pic

    I then downloaded the latest stable version of OpenCV 3.0.0 and configured it using ccmake. When I try to make -j8, it gives me the following error.

    However without ffmpeg support it works fine. However I need ffmpeg support due to the nature of my work.

    In trying to resolve the problem, I tried installing OpenCV 2.4.11 but it also gave this error. The latest GIT version does not give me this error but rather an error a part of which goes like this

    Linking CXX shared library ../../lib/libopencv_highgui.so /usr/bin/ld: /home/matheus/ffmpeg_build/lib/../lib/libavcodec.a(avpacket.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used

    I have pasted the above error from another unresolved question online and so the folder names are different but the relocation error is exactly the same.

    In trying to resolve the problem I searched and found the following link http://answers.opencv.org/question/12597/build-problems-for-opencv-241-with-ubuntu-1204-lts/

    However, one of the answers over there mentioned changing some lines in cap_ffmpeg_impl.hpp file. I tried doing that but either i am not able to do it correctly or something else is going wrong and it is not working. Exact line numbers and exact changes are not mentioned and so I am having difficulty changing things and being sure.

    I am using Fedora 19 (Schrodinger Cat) as the operating system I hope the details of my question are clear and I hope that the community would oblige me with a good response.
