• How to fix "fatal error : x.264 no such file or directory"

  24 avril 2019, par user11340790

  I wrote a makefile which builds a C program attaching the x.264 header. After trying to execute the makefile in terminal I receive the fatal error :
"example.c line [line of #include ] x264.h no such file or directory". Below you can find the C code and makefile (located in the same folder, the library - containing the x264.pc file- is in the folder libx264 of the parent folder). I would be very grateful if you could help with the linkage.

  



  Makefile :

  



      CC = gcc

    CFLAGS = -c -Wall `export PKG_CONFIG_PATH=../libx264 && pkg-config            --cflags x264`
    LDFLAGS = -static `export PKG_CONFIG_PATH=../libx264 && pkg-config --libs --static libx264`


    all: Release

    Debug: CFLAGS += -g
    Debug: example

    Release: example

    test: example.o
        $(CC) -o example example.o $(LDFLAGS)

    test.o: example.c
        $(CC) $(CFLAGS) example.c -o example.o

    clean:
        rm -f example.o example


  



  example.c code

  



      #include 
    #include 
    int main( int argc, char **argv )
    {
        int width, height;
         return 0;
    }


  


• ffplay and ffmpeg subtitles/ass filters errors/crash

  23 octobre 2014, par Mr Almighty

  I’m trying to use ffplay with subtitle and embed/burn a subtitle in a video.
  I tried to load a .mkv file with a subtitle burned/embed in ffplay and nothing, tried using the -sst option, and nothing. Then I tried subtitles filter with a .mp4 file and a .srt file. :

  ffplay video.mp4 -vf subtitles="video.srt"

  ...and I got this error :

  [Parsed_subtitles_0 @ 00000000064956e0] No usable fontconfig configuration file found, using fallback.

  Fontconfig error : Cannot load default config file

  I realized that MPlayer generates a font folder with the config file on it, then I copied that folder, placed in the same folder that ffplay is located, and... errors :

  Fontconfig warning : FcPattern object size does not accept value 0

  And then it crashes.

  I tried the same with ffmpeg :

  ffmpeg -i video.mp4 -vf subtitles="video.srt" output.mp4

  And the same errors and crash.

  What am I doing wrong ? And how can I fix this ?

• MoviePy failing to execute because it cannot find ffmpeg on my macOS

  I have a macbook pro running sonoma latest version, i have installed ffmpeg with brew and its located at /opt/homebrew/bin/ffmpeg

  


  Im trying to run this script but i get the error :

  


  from moviepy.editor import *

        ((12, 16), 'subs4')]

subtitles = SubtitlesClip(subs, generator)

video = VideoFileClip("video.mp4")
result = CompositeVideoClip([video, subtitles.set_pos(('center', 'bottom'))])

result.write_videofile("output.mp4", fps=video.fps, temp_audiofile="temp-audio.m4a", remove_temp=True, codec="libx264",
                       audio_codec="aac")



  


  error :

  I tried reinstalling ffmpeg and installing it in the env of the project but still no luck.
