• Download a video from blob:https url from eventive

  26 août 2020, par jjcasmar

  I want to download a video from eventive but the tag contains a blob url (blob :https://watch.eventive.org/**************).

  


  I have been reading some answers to similar questions but they all assume that the video has a mp3u8 file extension, which in my case doesn't.

  


  I have also tried to directly download that url (removing the blob :) with curl, but I obtained a html code which I cant really understand, which contains a lot of references to javascript files.

  


  Any tip would be really helpful.

  


  Edit :

  


  I have been doing some more tests and I have been able to found a url to a manifest file which points apparently to the video data. I have tried to open that url using VLC and it loads some info about the video, and it even plays it, but the screen is completely black.

  


  I have also tried to download it using ffmpeg but it gives a bunch of errors.

  


  ffmpeg -i https://eventiveprod-usea.streaming.media.azure.net/02968382-069a-4f02-ab3b-67c0b5a8d5b7/5f427f2d65a569006ebd326c.ism/manifest\(format\=mpd-time-csf\)  output.mp4

• ffmpeg - strange timestamps after concatenation

  25 août 2020, par codefox

  I want to cut some scene from video to other file, but also avoid lenghty encoding. In order to do it, i have to generate two sub video files : first file with encoding from start position to nearest position with keyframe, and second file with copy stream (without encoding), from keyframe to end position. So I have two files, and then merge them using concat, and result is not ideal. first frame do not start from 0.0 sec is longer than expected. These issues do not appear, when audio stream is disabled while generating two videos.

  How to generate these files, merge them with stream copy, and final video will start from 0.0 and have uniform frames duration ?

  


• How to accelerate minterpolate in ffmpeg ? [closed]

  24 août 2020, par Ken

  I'm using minterpolate of ffmpeg(version git-2020-08-21) with this command on Windows 10 :

  


  ffmpeg -i $file -filter:v "minterpolate=mi_mode=mci:me_mode=bidir:mc_mode=aobmc:vsbmc=1:fps=60" -c:a copy "$file_60fps.mp4"


  


  But the CPU load is only about 15% to 20% while working.

  


  My CPU is AMD 4800H with 8 cores and 16 threads. And I have a NVIDIA GTX1650 with CUDA.

  


  But I cannot find any document about GPU acceleration or multithread methods of minterpolate.

  


  Have tried -threads 16 but nothing changed.

  


  So how to accelerate the process ?
