  • Bash, Relative Paths, and Mac Automator Fails

    30 septembre 2015, par grahama

    This script works great in the terminal but fails when I run the shell script in automator (mac). For some reason, automator doesn’t remember the gif’s name and writes the file as *.gif. When run directly in Terminal, the script correctly converts to movie file to Gif and moves it to the correct Dropbox location.
    I’m trying to run this automator Mov2Gif script when Apple Motion 5 finishes rendering a movie.

    Any help is appreciated. Automator is a little touchy.

  • Overlying video frames using FFmpeg in c++

    14 mai 2020, par Bruce

    I am trying to overlaying two videos using FFmpeg in c++. So I followed the FFmpeg page and followed this command in terminal.

    



    $ ffmpeg -i Right.mov -i Left.mov -filter_complex "[0:v][1:v] overlay=0:0"  -c:a copy output.mov


    



    I can implement this functionality through the terminal, but I am trying to achieve this functionality through codding.

    



    typedef struct {
    AVFormatContext *fmt_ctx;
    int stream_idx;
    AVRational time_base;
    AVStream *video_stream;
    AVCodecContext *codec_ctx;
    AVCodecContext *pCodecCtxOrig;
    AVCodec *decoder;
    AVPacket *packet;
    AVFrame *av_frame;
    AVFrame *gl_frame;
    AVFrame *out_frame;
    AVStream *pStream;
    struct SwsContext *conv_ctx;


    



    also, I show some example code, but I am not sure about it

    



    https://ffmpeg.org/doxygen/2.1/doc_2examples_2filtering_video_8c-example.html

    



    and 
https://code5.cn/so/c%2B%2B/2601062

    



    AVFilterContext *buffersink_ctx;
AVFilterContext *buffersrc_ctx;
AVFilterGraph *filter_graph;


    



    how can I implement this functionality in my code ?

    


  • Can I see what ffmpeg.exe in task manager is doing ?

    28 février 2023, par miitchel

    So I use a program that starts ffmpeg processes in the background, is it possible to open one of those processes in the Windows terminal so I can see what it is doing ?
