Add 2 pictures to video with durations ? [duplicate]
24 juin 2013, par jesperThis 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");Here is output :

reading video mpegts stream from stdin using libavformat libavcodec
1er février 2012, par D StarkweatherI'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, &tty) == 0) {
oldtty = tty;
restore_tty = 1;
atexit(term_exit);
tty.c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP
|INLCR|IGNCR|ICRNL|IXON);
tty.c_oflag |= OPOST;
tty.c_lflag &= ~(ECHO|ECHONL|ICANON|IEXTEN);
tty.c_cflag &= ~(CSIZE|PARENB);
tty.c_cflag |= CS8;
tty.c_cc[VMIN] = 1;
tty.c_cc[VTIME] = 0;
tcsetattr (0, TCSANOW, &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.

Suppress output from popen()
18 février 2012, par Juan Gabriel Calderón-PérezIs there a way to suppress the output from
popen()without losing the Wait().Test 1 :
FILE * stream = NULL;
char buffer [120];
stream = popen ("ffmpeg -y -i test.amr -ar 16000 test.wav -v quiet", "r");
while (fgets (buffer, sizeof(buffer), stream))
{
}
pclose (stream);Test 2 :
FILE * stream = NULL;
char buffer [120];
stream = popen ("ffmpeg -y -i test.amr -ar 16000 test.wav -v quiet &> /dev/null", "r");
while (fgets (buffer, sizeof(buffer), stream))
{
}
pclose (stream);The problem with Test 2 is that
pclose()is not waiting for the pipe to finish processing. I don't want to have a bunch of FFMPEG output every time I have to do a pipe.
