  • Use FFMPEG to create video from jpeg, and index using vlc

    16 novembre 2011, par Greg

    OpenSuse 11.4
    FFMEG 0.8.5

    I'm using FFMPEG to create a 5 minute mpeg from about 2100 individual jpegs (7fps). I've been using the following command (OpenSuse 11.4)
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg

    Now I Try to open the file (In windows XP with VLC 1.1.11 Player).
    Media->AdvancedFileOpen
    *I select "Show more options" and set StartTime to 5s. I expect that the video should start 5 seconds in, but instead it starts at a seemingling random (although consistent) time of 30 seconds in.

    I also tried changing ffmpeg command to :
    /usr/bin/ffmpeg -sameq -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg
    *This result in about a constant 2x offset (5sec => 10sec) (10s => 20s) etc. But filesize is also about 6x larger, which is a strain on my storage.

    I also tried
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 -f mpegts Event-3692-r1-s1-3.mpg
    *This result in vlc not indexing at all into my video. Also not desired. Anybody have any clues what is going on here. It is very important for me to be able to use this VLC feature and have it work correctly.

    Thanks in advance

  • How to avoid a growing delay with ffmpeg between sound and raw video data ?

    13 novembre 2011, par roland

    Hello everybody and thank you for reading !

    Here is my problem : I have a program piping raw video frames to the standard output. This program is using OpenCV to capture and process the video and outputs directly the processed frames. The loop is synced to the framerate I chose. I'm using ffmpeg to read from the standard input and everything works fine for the video.
    But now that I added the sound I have a big problem : a growing delay is occuring and I really need to get rid of it. So here is my idea, but I really need your help :

    I have to find a way to include a timestamp information to the raw video. To be understandable by ffmpeg, it needs to be a known raw video compatible container. And then I will need to use the container API and pipe it to the standard output in my program. I really do not know what to use in the jungle of video formats and codecs, and I don't event know how to enable timestamp synchronizing in ffmpeg...

    If anyone has an idea, i am really interested here. For information, here is the command line i use to pipe the raw video :

    ./myprogram | ffmpeg -y -f alsa -i pulse -ac 2  -f rawvideo -vcodec rawvideo -r 24 -s 640x480 -pix_fmt bgr24 -i - -vcodec libx264 -pix_fmt yuv420p -r 24 -f flv -ar 44100 out.flv;

    Thand you very much,

    Roland

  • Facebook video upload [closed]

    2 février 2012, par Ahmet Kapıkıran

    I can't add subtitle to an avi file with mencoder. The length of avi videos are about 100 minutes. I split the videos to 19 minutes parts with ffmpeg and x264 codec and then I upload the video to user's facebook account with my facebook application. So, facebook starts to encode the video but after a period of time the video suddenly is removed by facebook. What is the problem. Is there a time period limit to send video to facebook profile or is my problem about codecs ?
