  • 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.

  • Using ffmpeg to pipe Logitech C920 video to two outputs : re-encoded to RTMP stream and hardware-encoded to file

    18 décembre 2018, par Maros Hluska

    I’m trying to use ffmpeg to accept video from a Logitech C920 and broadcast it to an RTMP stream (e.g. Twitch). But there’s a twist : I would like to also save to file the original 1080p hardware-encoded video.

    So I would like to do both of these :

    1. Re-encode the input to 852x480 resolution and upload to an RTMP url with 1500 bitrate
    2. Save the original input to a file without re-encoding (C920 does hardware encoding with the h.264 codec)

    I’ve tried saving the video to file without re-encoding using the following :

    ffmpeg -s 1920x1080 -framerate 30 -pixel_format uyvy422 -vcodec h264 -f avfoundation -i 'HD Pro' -copyinkf -vcodec copy out.mp4

    This seems to almost work. The webcam light turns on and a few seconds of running this produces a massive file (1GB or so). However, I can’t seem to open the file with VLC. I do see a warning from ffmpeg :

    [AVBSFContext @ 0x7fbd4fc3e9c0] No start code is found.
    
HD Pro: could not find codec parameters

    I’m on a Mac using ffmpeg 4.1.

    Edit :

    It seems the file that ffmpeg produces is not h264 encoded but rather raw pixel data. I’m starting to think that it’s not possible to set the webcam into the h264 mode with Mac (most other cases do it in Linux with v4l2).

    To anyone answering the question, I’d be happy with a solution that involves Linux as well. Especially if I can use a bootable live USB.
