  • download hls from m3u8 file with a particular resolution with ffmpeg [on hold]

    22 octobre 2018, par C.J.

    hi i am a new member of this site after looking at this site for hours i found how to download HLS from a site and it works also. but one thing i could not find is if a particular site has available video in more than one resolution say 1280*720 and 1920*1080. so how do i tell FFMPEG to download 1280*720 and not 1920*1080. this is the code i tried.

    ffmpeg i "https://hsprepack.akamaized.net/videos/hotstarint/world/kwks6/1_2/master.m3u8?hdnea=st=1540178095 exp=1540179895 acl=/* hmac=ee2361306de510cf4f372c359b5ec21fd3d3b61d65b6f5e2f16259508e08c625" output.mp4

  • Standardizing many mp4 files into same resolution

    22 novembre 2018, par Cowfod

    I have a huge collection of Instagram videos in different resolutions and with different audio codecs.

    Some videos are 640x640, others are 640x800. You get the picture.

    When I try to concat the videos, the video and audio go out of sync in the final output and the in some places the audio is slowed down(?).

    This is my ffmpeg concat command :

    ffmpeg -i "$(cat /home/list.txt)" -c:v copy -c:a copy /home/output.mp4

    list.txt contains over 800 clips and is formatted correctly :

    file 'clip1.mp4'
    
file 'clip2.mp4'
    
file 'clip3.mp4'
    
etc...

    I believe the issue is due to all the different resolutions and different codecs used, so how can I standardize my collection of clips in order to concat them into a working video file ?

  • Dynamic video resolution

    4 janvier 2019, par Chen Yang

    I use ffmpeg to encode my mobile phone’s screenshot to a video. when my phone is vertical the screenshot’s resolution is 478 * 850.When horizontal the resolution is 850 * 478. Encoder could handle these image to encoded video frame, and i could play this video by ffplay correctly, i means if resolution change from 478 * 850 => 850 * 478 and it still could display full phone screen. enter image description here enter image description here
    But if i play this video with any other players, it only could play harf of phone screen when frame resolution change from 478 * 850 => 850 => 478.
    enter image description here
    Do you guys know any video format could handle this situation？
