  • How to write frames to a video file ?

    20 juillet 2019, par Mike Chen

    I am currently writing an application that read frames from camera, modify them, and save them into a video file. I’m planing to do it with ffmpeg. There’s rarely a documentation about ffmpeg. I can’t find a way. Does any know how to do it ?

    I need it to be done on unix, and in C or C++. Does any can provide some instructions ?

    Thanks.

    EDIT :

    Sorry, I haven’t write clearly. I want some developer APIs to write frames to a video file. I open up camera stream, I get every single frame, then I save them into a video file with those APIs available in ffmpeg’s public apis. So using command line tool actually doesn’t help me. And I’ve seen output_example.c under the ffmpeg src folder. It’s pretty great that I may copy some parts of the code directly without change. And I am still looking for a easier way.

    Also, I’m thinking of porting my app to iPhone, as far as I know, only ffmpeg has been ported on iPhone. GStreamer is based on glib, and it’s all GNU stuff. I’m not sure if I can get it work on iPhone. So ffmpeg is still the best choice for now.

    Any comments is appreciated.

  • OSX/Cocoa app crashing when finished running ffmpeg terminal command

    23 juin 2014, par codeman

    I’m running ffmpeg within my Mac app and it’s actually creating the output file successfully. The problem is that the app crashes as soon as the ffmpeg command is finished. Any ideas on how to prevent the crash ?

    Here’s the code I’m using to run ffmpeg in my Mac app :

    char ffm_cmd[512];
    
NSString *command = [NSString stringWithFormat:@"%@%@ \\\n-filter_complex '[0:0][1:0][2:0][3:0]concat=n=%d:v=0:a=1[out]' \\\n-map '[out]' %@/output.wav", escapedPath, concatFiles, count, self.outputFolderPath];
    
const char *cString = [command cStringUsingEncoding:NSASCIIStringEncoding];
    
sprintf(ffm_cmd,cString);
    
system(ffm_cmd);
