• How to install ffmpeg and an app together on a Mac ?

  30 juin 2016, par Patrick

  I have an electron app built and packaged for macOS in a .app file. The app requires ffmpeg to be installed on the end-user’s computer to be used.

  Currently, I’ve had to manually install ffmpeg on each end-user’s computer to run the app.

  I want to distribute the app online with an easy installer for both ffmpeg and the app. I’ve seen .dmg files which allows you to drag the .app into the applications folder easily, but the ffmpeg dependency is still absent in the installation process.

  How can I install ffmpeg and the app together on a mac ?

  Perhaps including the ffmpeg build in the .app content is a solution as well.
  This may not be possible though because a relevant question mentions there are only abstractions of the ffmpeg CLI instead of something that can directly use ffmpeg.

• FFMpeg is writing a matplotlib animation with diminishing quality

  3 mars 2017, par Bryan Stafford

  I am trying to create a bunch of animations that follow the paths National Hockey League teams travel during the current season. Currently, my animation looks like this.

  As you can see, the animation begins decently sharp but within 2 seconds the quality bottoms out and everything is grainy.

  The relevant code is this :

  ani = animation.FuncAnimation(fig, update, frames=len(all_x + 20), 
  
                                interval=75, repeat=False)
  
  filepath =  map_team + '.mp4'
  
  ani.save(filepath, writer='ffmpeg', fps=30)
  
  plt.tight_layout()
  
  plt.show()

  I have chosen FFMpeg as my writer because I hope to put about 30 graphics online and the MP4 format keeps each file around 1.5MB. If there’s a way to keep the graphics sharp, with low file sizes, and able to be uploaded onto Imgur, I would love to do that with my project.

  Thanks.

• Adding Mediainfo into Videos

  13 août 2019, par yrcje

  I’m trying to add/preserve these datas while recording/editing .TS footage, (datas will be shown below), I’m using VideoReDo TVSuite5 to edit these .ts/.tp files without losing these datas, as from what I know, VideoReDo software automatically removes these miscellaneous data from the stream, I’m trying to preserve it while editing, or adding it back after editing, is there any way to do this ?

  Not much as I can’t really find any documentation on Menu info editing online. From what I can see so far, these data can only be obtained if the source itself is from a Native Internet TV Box. But is there any other way around it ?

  Menu #1
  
  ID                                       : 32 (0x20)
  
  Menu ID                                  : 2 (0x2)
  
  Duration                                 : 1 h 25 min
  
  List                                     : 33 (0x21) (MPEG Video, Korean) / 36 (0x24) (AC-3, Korean)

  The Mediainfo is inside the pastebin link.
