• any solution to Matlab VideoReader on compressed avi file on Mac ?

  3 décembre 2016, par Peng JL-Zhulin

  I am working on some video gamma correction. And I used some sample avi uncompressed clips from online, everything works just fine.
  But once I try to use our own .avi video 1280x800 20 second about 400mb, Matlab can not read file through ’VideoReader’.

  I’m really sure the problem is that my video is compressed avi. And I have tried the following to solve it :

  1. some say in mac os, download gstreamer 0.10 may help. I did, but problem remained.
  2. i tried to use ffmpeg to convert the compressed avi to uncompressed avi (i dont think i am supposed to do this tho). but the new uncompressed video became a mess.

  So, I was thinking, when working on compressed avi file in MATLAB in mac, is there a godd routine that people follow ?

  Thanks a lot.

• FFMPEG, any video to 16:9

  13 décembre 2019, par Universal

  Help me find a command or script that will convert any video to 16:9, h264 and 2500kbps. I have a server where people upload videos of different quality, size and length. It can be either 640x480 or 1216x2160. Ultimately, I need to get any resolution to 16:9 (with black borders, if needs) and bitrate without visible loss of quality, which will be acceptable for online broadcasting.

  I have this command, but it does not check the resolution of the video. And if the video was 560x448 1000kbps and 700mb, then after conversion it will be 1280x720 3000kbps and 1.5gb, that’s not right.

  ffmpeg -i 5.avi -vcodec libx264 -crf 23 -preset veryfast -vf scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1 -tune zerolatency highoutput.mp4
