• How to merge several videos in a grid, in one video ? [closed]

  14 mai 2021, par Kayra Uckilinc

  I have 36 video files with same dimensions and want to concatenate them into a one single video with 6x6 grid.

  


  Ideally is non-square number of videos are given for example 12, a 4x3 grid as the most square it can be would be great.

  


  I tried with matplotlib's animation library but failed to concatenate videos in both directions first as row then as columns.

  


  Any help is appriciated !

  


• Facebook Graph API - Getting error 2207026 when trying to upload video

  22 novembre 2022, par NiVeK92

  I try to upload a video via the graph API but as the title states, I get an error that states that I use an unsupported video format.

  


  I thought maybe the original video file doesn't match the video specifications as defined on https://developers.facebook.com/docs/instagram-api/reference/ig-user/media#video-specifications so I wrote a function to convert the file to match the specification, using ffmpeg with the following command (I tried many different ones, but this is the last one I tried)

  


  ffmpeg -i ${tmpInFile} -vf format=yuv420p -vf scale=-2:720 -pix_fmt yuv420p -r 30 -movflags +faststart -c:v libx264 -b:v 3M -c:a aac -b:a 128k -ac 2 -ar 44100 -shortest -f mp4 ${tmpOutFile}

  


  Unfortunately, the error persists.

  


  Here's the complete process :

  


  First I use await fetch('/api/convert-mp4', { method: 'POST', body: file }); to send the uploaded video file to the backend.

  


  Next I get the blob data from the request with const blob = await request.blob();.

  


  Then I create a temporary file with await fs.writeFile(tmpInFile, await blob.stream()).

  


  Then I call ffmpeg with the above command mentioned above and then read the file with const buffer = await fs.readFile(tmpOutFile);.

  


  Then I send the buffer as response body back to the client with return {status: 200,body: buffer}.

  


  Then I get the blob data from the response with const blob = await convertVideoResponse.blob();.

  


  Finally I convert it back into a file object with
const convertedFile = new File([blob], file.name, { type: 'video/mp4' });

  


  This file I upload to Supabase Storage (https://supabase.com/storage), and get a publicly accessible url (which I confirmed by opening it in an incognito tab).

  


  In the supabase dashboard I can see the video file has the correct media container (video/mp4) and the file size is small enough.

  


  Does anyone have an idea what could be the issue ?

  


  Edit :

  


  By changing the ffmpeg command to use h265 instead of h254 ffmpeg -i ${tmpInFile} -vf format=yuv420p -vf scale=-2:1350 -pix_fmt yuv420p -r 30 -movflags +faststart -c:v libx265 -vtag hvc1 -an -x265-params crf=25 -b:v 3M -c:a copy -c:a aac -b:a 128k -ac 2 -ar 44100 -shortest -f mp4 ${tmpOutFile} I managed to get it to work for some videos but not all, which confuses me, as I assumed that the video attributes should be the same for all videos processed by the same command.

  


• Destreamer (FFMPEG / Youtube-DL) - Can't download video, Invalid DTS, Invalid timestamps message

  1er avril 2020, par toprun91

  I'm using Destreamer a program that essentially lets you download microsoft stream videos by passing a key URL with a cookie down to Youtube-dl which then calls into ffmpeg.

  



  Whenever I try to download a video using this program I get tons of repeating lines of text (errors ?) like this :

  This continues to fill the screen and scroll with the same type of lines of text and then after a couple of hours it does eventually download the video but without sound.

  



  I am trying to work out why this is happening and why the video downloads without sound.

  



  Some key information :

  



  

  • I am using windows + powershell but also experience the same thing on
Linux (Kubuntu)

  


  • I am using the latest versions of FFMPEG, youtube-dl node.js

  


  • The program (destreamer) brings up a chromium window to authenticate.
In the Chromium window the video doesn't actually play properly and
gives Error code 0x20400003 The video plays fine in all other
browsers I have including Edge, Chrome, and Firefox

  


  



  Thanks for your help !
