• How to download .ism files protected by DRM (Widevine or IIS Smoth Streaming)

  16 septembre 2019, par Foopy7774

  I’m struggling to download a video which is protected by DRM or something else (idk)...I tried to download it by using VLC, ismdownloader, ffmpeg and youtube-dl but the video seems encrypted. There bound to be a way to do it, given that Chrome is able to read it...

  I’ve seen that they are using Widevine or IIS Smooth Streaming, I don’t really know...but if you can’t answer my post, can you atleast set me on the right path by telling me :
  What they use ? Widevine ? IIS Smooth Streaming ? Both ?

• Is it possible to merge 3 videos with ffmpeg by -f concat and crossfade without video content

  10 août 2019, par user3792705

  I want to merge 3 .mov files quickly without losing any resolution. I want to be able to distinguish the 3 pieces of videos after merge.

  "ffmpeg -f concat" does not lose resolution and quick without crossfade.

  But, I can’t distinguish 3 videos.

  As far as I know ffmpeg filter can be used add crossfade, but it have to use video start/end content to do the merger, which might involve transcoding. It won’t be fast compared with ’concat’, which won’t do transcoding, but simply copying.

  Here is the content (ffmpeg -i video.mov) of one of 3 videos :

  If I don’t care about crossfade with video content, just some ’nice’ black screen in between (It would be nice I add some text, like date + time on the black screen) is good enough for me. Is it possible to do ’concat’ and simple crossfade without video ’content’ ?
