• Installed ffmpeg, added to path, still can't save animation from Jupyter Notebook

  29 avril 2017, par dredre_420

  I’m trying to simulate a two-body orbit system working on Jupyter Notebook (python). Since the animation can’t display in-line I tried installing ffmpeg and adding it to the system path using steps outlined here : http://adaptivesamples.com/how-to-install-ffmpeg-on-windows/.

  However, when I try to save my animation using anim.save('orbit.mp4', fps=15, extra_args=['-vcodec', 'libx264']), I still get the error message : ValueError: Cannot save animation: no writers are available. Please install mencoder or ffmpeg to save animations.

  Not sure what else to try at this point, very inexperienced programmer here.

• How to create m3u8 playlist from mp4 video url ( stored in amazon S3 ) and store the video chunks ( .ts files) and .m3u8 file back to another S3 ?

  19 mai 2019, par dexter2019

  I am building an application where user can upload video and others can watch them later. I am aiming for HLS streaming of the video on the client side, for which the video format should be .m3u8. I am using node fluent-FFmpeg module to do the processing, however, I have a huge doubt, that, how to ensure that all the .ts files (chunks) are also stored back in s3 bucket along with the m3u8 file after ffmpeg processed the mp4 file ?

  Because the ffmpeg command only takes the location of the m3u8 file ? How handle it when I want the input and output location to be S3 ?

  Any help will be greatly appreciated.

  I am following the answer from this question Ffmpeg creating m3u8 from mp4, video file size , which is working absolutely fine in my local machine, how to achieve the same for s3 ?
