Ubuntu - Compile only ffmpeg.c from ffmpeg source
29 août 2016, par ArlindI’m experimenting with the ffmpeg.c file from the ffmpeg source code but every time I want to test what I’ve changed it takes about 15-20 mins to compile the whole thing. Is there a way to compile only the ffmpeg.c file (which is the only file I’m making changes) ?

Start service with start-stop-daemon on Ubuntu 16.04 with timeout
26 février 2018, par TopperI have /etc/init.d/stream proces with start/stop/restart options.
It’s run ffmpeg with daemon options taken from /etc/default/stream DAEMON_OPTIONS.
Start at background (-b) crate pid (/var/run/stream/stream.pid) etc.How could I add timeout 60 seconds to be sure that stream will be forcebly stopped if exceed 60 sek. timeout ?
Can’t run "—exec timeout 60 ffmpeg" because service runs only timeout command.
I’m I missing something or try to use wrong command ?

Ffmpeg library compilation .(without pkg-config) in linux ubuntu
2 novembre 2023, par Mohideen IrfanI have been trying to use ffmpeg libraries in my C code. But when i compile those libraries using pkg-config tool in linux terminal it works. But when i directly linked all the necessary libraries , it won't work. I even specified the library path in -L flag and LD_LIBRARY_PATH. even included the -I flag correctly. But when i use pkg-config it works, if i use directly it wont work. I also export LD_LIBRARY_PATH.


here is my C program Sample.c :


#include 
#include <libavformat></libavformat>avformat.h>


int main(int argc, char *argv[]) {
 if (argc < 2) {
 printf("Please provide a video file as an argument.\n");
 return -1;
 }

// av_register_all();

 AVFormatContext *pFormatCtx = NULL;
 if (avformat_open_input(&pFormatCtx, argv[1], NULL, NULL) != 0) {
 printf("Could not open the file.\n");
 return -1;
 }

 if (avformat_find_stream_info(pFormatCtx, NULL) < 0) {
 printf("Could not find stream information.\n");
 return -1;
 }

 av_dump_format(pFormatCtx, 0, argv[1], 0);

 avformat_close_input(&pFormatCtx);

 return 0;
}


here is the package file of libavformat.pc :


prefix=/home/mohideen-ts205/ffmpeg_build
exec_prefix=${prefix}

includedir=/home/mohideen-ts205/ffmpeg_build/include

libavutil.pc :

Libs.private: 
Cflags: -I${includedir}


And here the command :
with pkg config- working one :


gcc -o sample sample.c $(pkg-config --libs libavutil libavformat libavcodec)


without it directly linking :


gcc -o my_program -I/home/mohideen-ts205/ffmpeg_build/include -L/home/mohideen-ts205/ffmpeg_build/lib -lavformat


NOTE : I even tried to copy all the library files mentioned in libavutil.pc and libavformat.pc, but still i am getting this undefined reference error. what kind of problem it is.
