  • FFMPEG add audio to a video but clip it to the video length

    5 novembre 2011, par Daniel Lloyd-Wood

    I'm trying to create a video from an image sequence and add audio with FFMPEG

    The frame sequence is only 25 frames long but the audio is several minutes. I want FFMPEG to clip the audio to the length of the frame sequence.

    This is the command I have tried :

    ffmpeg -i input_images%04d.jpg -pix_fmt yuv420p -vcodec mjpeg -qmin 1 -qmax 1 -r 25 -i audio_file.mp3 -ar 22050 -ab 192k -aframes 25 output.mov

    This results in a video with the first image sequence but the full length audio. -aframes is ignored. Any ideas ?

  • Texai Remote Presence System Using VP8 Video

    19 novembre 2010, par noreply@blogger.com (John Luther)

    Guest blogger Josh Tyler is a member of the Texai team at Willow Garage.

    Willow Garage is busy building the next version of its Texai remote presence platform with VP8, the video codec used in WebM.

    In short, Texai is a two-way videoconferencing app on a tele-operated robotic platform (for more details, see the piece about Texai in the New York Times). Video and audio quality are critical to providing the best user experience on Texai. We’ve evaluated several video codecs and found VP8’s image quality, low latency and tolerance to packet loss far better than anything else we tested.

    The video below shows VP8 running on one of our systems.

    (If you have a WebM-enabled browser and are enrolled in the YouTube HTML5 beta the video will play in WebM HTML5, otherwise it will play in Flash Player.)

    We’re also looking for help ! If you’re interested in helping us create an incredible, high-fidelity user experience, either by joining our team, partnering on development, or by being added to our early customer interest list, please email us at texai-info@willowgarage.com.

  • FFmpeg : How to split video efficiently ?

    8 mai 2017, par Antony

    I wish to split a large avi video into two smaller consecutive videos. I am using ffmpeg.

    One way is to run ffmpeg two times :

    ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi
    
ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi

    But according to manpage of ffmpeg, I can make more than one ouput file from one input file using just one line :

    ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi \
    
   -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi

    My question is, does the later approach save computation time and memory ?
