  • how to check the number of duplicated frame for video 1sec ( about 30frames ) from video start and want to apply this for mpdecimate

    20 octobre 2018, par cool jobs

    How to check the number of duplicated frame for video 1sec ( about 30frames ) from video beginning point ? I want to apply this for mpdecimate with audio. Some videos have three duplicated frames, some videos - 15 duplicated frame, some videos have 19 duplicated frames.. so it looks I need a variable or math operator in ffmpeg as expression.

    1. some video have duplicated frames at beginning point , but it is
      not same always the number of duplicated frames.
    2. if get back variable which is for the number of duplicated frames
      from step-1 then split and trim apply mpdecimate with audio as
      much as step-1 variable returned, finally do concatenate each other.

    Is this possible with -filter_complex for one line ffmpeg command ?

  • ffmpeg Invalid data found when processing input

    20 mai 2019, par Sulli

    I’m trying to download a specific part of a youtube video with this code :

    step=`youtube-dl -g -f 'bestvideo[ext=mp4]' https://www.youtube.com/watch?v=pMntMsHTDZ0`
    
ffmpeg -nostdin  -i "$step" -ss 00:00:10.00 -t 00:00:02.00 -c copy frames/out.mp4

    but I’m getting this error :

    https://manifest.googlevideo.com/api/manifest/dash/requiressl/yes/source/youtube/id/a4c9ed32c1d30d9d/itag/0/ei/fG7iXMihC8_oxwK0qJ-YAQ/playback_host/r6---sn-n4g-jqbd.googlevideo.com/mm/31%2C26/mn/sn-n4g-jqbd%2Csn-5hne6n7s/ms/au%2Conr/mv/m/pl/22/hfr/all/as/fmp4_audio_clear%2Cwebm_audio_clear%2Cwebm2_audio_clear%2Cfmp4_sd_hd_clear%2Cwebm2_sd_hd_clear/initcwndbps/716250/mt/1558343198/fvip/4/ip/79.86.92.133/ipbits/0/expire/1558364892/sparams/ip%2Cipbits%2Cexpire%2Crequiressl%2Csource%2Cid%2Citag%2Cei%2Cplayback_host%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Chfr%2Cas%2Cinitcwndbps/signature/D046699C35F9AFF84334BAB20E1D8D4CA5318794.6EF1739E2ED134D16EBBE9242BDDE31F59801AAB/key/yt8: Invalid data found when processing input

    I don’t understand this error, and this code has worked for tens of videos I’ve downloaded before.

    How to fix this or get more information on the error ?

  • How to calculate the "Range" header for mp4 file to play/download a part of it ? [youtube-dl]

    5 décembre 2016, par supersan

    I’m using youtube-dl to download videos from YouTube. Unfortunately, sometimes I just need to download a part of the video like 10 seconds of a 3 hour video and here is how I see I can do it.

    Step 1 : Get the URL of the mp4 file from youtube-dl.

    youtube-dl -g -f "[ext=mp4]" https://www.youtube.com/watch?v=qOZ1u9VpoMk

    This returns $url : the full URL of mp4 file on server.

    Step 2 : Download part of the video using curl

    curl -r $startBytes-$endBytes $url

    But how to calculate $startBytes and $endBytes. What is the formula for that ?

    P.S I was thinking could be something as simple but this isn’t it..

    $startBytes = (total_size_of_video / total_length_of_video_secs) * start_seconds

    P.P.S. When I play the mp4 video in Chrome and use the scrub bar to jump around in the video, Chrome too send the Range header to the same URL (as I can see in fiddler)
