  • How to fix the "No working C compiler found." problem for compiling x264 in Linux ?

    27 février 2023, par gc xu

    Firstly I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I git clone the source code from https://code.videolan.org/videolan/x264.git.
Then, I run command ./configure, it shows

    


    ./configure: line 169: conftest.log: Invalid argument

    I check the file "config.log". It shows :

  • ffmpeg "End mismatch 1" warning, jpeg2000 to avi

    11 avril 2023, par jklebes

    Trying to convert a directory of jpeg2000 grayscale images to a video with ffmpeg, I get warnings

    &#xA;

    What is the meaning of characters like [0 ;33m here ?

    &#xA;

    I thought it might have something to do with bit depth and color format. Setting -pix_fmt gray had no effect, and indeed the format of the jp2 images is already detected as 8-bit gray.

    &#xA;

    The output .avi exists and seems fine.

    &#xA;

    The line was previously used on jpeg files and works fine on jpeg. With jpeg, the output has the line

    &#xA;

    detecting mjpeg format and similar, but more detailed format gray(bt470bg/unknown/unknown), 6737x4869 [SAR 1:1 DAR 6737:4869].

    &#xA;

    What is the difference when switching input to jp2 ?
