  • reading video mpegts stream from stdin using libavformat libavcodec

    1er février 2012, par D Starkweather

    I'm trying to read video frames from stdin using ffmpeg's libav* lib collection. Simply passing "pipe:0" or "pipe :" as the filename to avformat_open_input_file() in my program does not do the trick. (e.g. cat /dev/video0 | ./myprogram OR ./myprogram < /dev/video0 ; it also fails using file.avi in place of /dev/video0).

    Peeking into ffmpeg.c, I find the following bit of code using tcsetattr() to set the termios :

    struct termios tty;
    

    
if (tcgetattr (0, &amp;tty) == 0) {
    
oldtty = tty;
    
restore_tty = 1;
    
atexit(term_exit);
    

    
tty.c_iflag &amp;= ~(IGNBRK|BRKINT|PARMRK|ISTRIP
    
                      |INLCR|IGNCR|ICRNL|IXON);
    
tty.c_oflag |= OPOST;
    
tty.c_lflag &amp;= ~(ECHO|ECHONL|ICANON|IEXTEN);
    
tty.c_cflag &amp;= ~(CSIZE|PARENB);
    
tty.c_cflag |= CS8;
    
tty.c_cc[VMIN] = 1;
    
tty.c_cc[VTIME] = 0;
    

    
tcsetattr (0, TCSANOW, &amp;tty);
    
}
    
signal(SIGQUIT, sigterm_handler); /* Quit (POSIX).  */
    
}
    

    
avformat_network_deinit();
    

    
signal(SIGINT , sigterm_handler); /* Interrupt (ANSI).    */
    
signal(SIGTERM, sigterm_handler); /* Termination (ANSI).  */
    
signal(SIGXCPU, sigterm_handler);

    However, when I try this, it appears to have no effect. What settings do I need in the termios struct to continuously read video frames in ?

    Currently, all i am able to do is call av_read_frames a few times (return code 0) before it usually either segfaults or hangs waiting. The buffer usually contains just a blank screen (all black). With any luck, the video buffer will contain the first video frame it comes across, but does not update to the later frames.

    (I'm running this on Debian 6.0) Here's my version of ffmpeg :

    Thank you very much for any help helpful tips. It is much appreciated.

  • Add 2 pictures to video with durations ? [duplicate]

    24 juin 2013, par jesper

    This question already has an answer here :

    I am trying to add 2 different images into a video with ffmpeg.

    image1.jpg should show the first 10 seconds of the movie and youtubeLOL.png should show the next 6 minutes of the video.

    So the command should tell us also to repeat the pictures to get a length for 6 minutes and 10 seconds. How can i do this ? I have tried this :

    (It's not even working)

     passthru("ffmpeg -f image2 -loop 1 -vframes 100 -i /home/psafari/public_html/youtube_images/movie_" . $id . ".jpg -vcodec mpeg4 /home/psafari/public_html/youtube_videos/movie_" . time().".avi");

  • Enabling rtmp_swfurl option in FFmpeg

    24 avril 2013, par Mustafe

    In Unix, in order to process RTMP live stream URLs some live streams needs swfurl, pageurl extra. We are able to pass this parameters to the RtmpDump and pipe it to the FFmpeg.

    However some FFmpeg has rtmp_swfurl its own. How can we enable this options in FFmpeg, not all of them have. Although I have latest version I do not have them.
