  • How to grab voice and video in ffmpeg/mplayer/mencoder ? [closed]

    4 février 2013, par Kill Kill

    My target is to grab voice and video via webcamera.
    There are three ways to do :

    1.ffmpeg

    ffmpeg -f oss -i /dev/dsp -f video4linux2 -r 25 -b 500000 -s 320x240 -i /dev/video0 out.mpg

  • Hardware accelerated video processing tools for Linux

    1er mai 2016, par geoffreak

    I am looking into options for command line video processing tools for Linux, but I am having a hard time find any. FFmpeg doesn’t support hardware acceleration as far as I can tell and I don’t see many alternatives.

    The machines that will be running the software are running CentOS and each has a NVIDIA Tesla card available. While the CentOS can be swapped with something else (not Windows), it would be great to have something that supports CUDA or OpenCL.

    I don’t have any strict requirements for what actually needs to be processed, but I just want to see what options are available for this hardware.

  • Live streaming to YouTube over HLS with FFMPEG [closed]

    19 septembre 2022, par Ash Raj

    When I stream my FaceTime camera to YouTube over HLS, my video freezes every couple seconds. Which settings do I have wrong, or am missing ?

    


    ffmpeg \
-f avfoundation \
-framerate 30 \
-video_size 1920x1080 \
-pixel_format yuyv422 \
-probesize 10M \
-i "0:0" \
-c:v hevc_videotoolbox \
-b:v 4500K \
-tag:v hvc1 \
-c:a aac \
-method POST \
-f hls \
"https://a.upload.youtube.com/http_upload_hls?cid=STREAM_KEY&copy=0&file=index.m3u8"


    


    I'm troubleshooting this with my FaceTime camera right now, but I plan on using a capture card with a 4K studio camera after I get this working
