  • webm dash encoding... What are the correct ffmpeg parameters ?

    24 avril 2020, par Dean

    I'm stumped with encoding videos into a dash compliant format. I'm going from .mp4 to .webm

    



    Firstly, I am running OS X and ffmpeg 2.5.4.

    



    Here's the encoding commands I am using in my test (I got these from here) :

    



    ffmpeg -i IMG_0113.mp4 -c:v libvpx-vp9 -s 160x90 -b:v 25k -g 1 -tile-columns 4 -frame-parallel 1 -an -f webm -dash 1 video_160x90_25k.webm

ffmpeg -i IMG_0113.mp4 -c:v libvpx-vp9 -s 160x90 -b:v 50k -g 1 -tile-columns 4 -frame-parallel 1 -an -f webm -dash 1 video_160x90_50k.webm

ffmpeg -i IMG_0113.mp4 -vn -acodec libvorbis -ab 128k  -dash 1 audio_128k.webm

ffmpeg -f webm_dash_manifest -i video_160x90_25k.webm -f webm_dash_manifest -i video_160x90_50k.webm -f webm_dash_manifest -i audio_128k.webm -c copy -map 0 -map 1 -map 2 -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1 id=1,streams=2" manifest.mpd


    



    Secondly, the problem is not with my server, as I have downloaded the samples from here, and they work 100% on the dash.js player when served from my local server.

    



    Please could someone out there point me in the right direction ? Or provide a sample of the ffmpeg commands used to get the output format correct.

    



    Thanks,
Dean.

  • OpenCV3 returning float FRAME_COUNT

    15 mars 2016, par mprat

    I am using OpenCV3 on OSX with Python 2.7 bindings. However, when I try to read the frame count of my video (a .mp4 video), it returns a float - I am expecting an int. Do I need to compile OpenCV3 with some special flags ? Am I missing some codecs ?

    import cv2
    
vid = cv2.VideoCapture("vid.mp4")
    
print vid.get(cv2.CAP_PROP_FRAME_WIDTH)

    And it returns a float.

    Installation details :

    • ffmpeg : brew install ffmpeg --with-dcadec --with-openh264 --with-openjpeg --with-openssl --with-tools --with-x265  --with-zimg --with-libvidstab --with-libvpx
    • opencv3 : brew install opencv3 --with-ffmpeg --with-contrib
