• Ffmpeg change resolution h.264

  9 janvier 2019, par PUBG Player Unknown Battlegrou

  I need to add a option to ffmpeg command to change the video resolution to 5760x2880 with keeping the right aspect ratio so the video isn’t distorted my current command is
  

   -i {INPUTFILE} -c:v libx264 -preset ultrafast -crf 0 -r:v 30 -c:a copy {OUTPUTFILE}

  Thank you

• ffmpeg conversion of jpg to mp4 fails due to to jpg frames change

  14 janvier 2019, par Sebastien Damaye

  I’m trying to compile a set of jpg (camera screenshots taken every 5 seconds) to a mp4. The ffmpeg command works fine but the resulting mp4 is missing some images. I noticed that the "holes" are created when the jpg "frames" is changing from 1 to 3 in the jpg sequence (see below result of file that shows frames 1 for the 1st jpg and frames 3 for the 2nd one) :

  $ file 20190110060113.jpg
  
  20190110060113.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1280x720, frames 1
  
  
  
  $ file 20190110060119.jpg
  
  20190110060119.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1280x720, frames 3

  And with ffmpeg, it sows :

  ffmpeg -i 20190110060113.jpg -i 20190110060119.jpg

  At least one output file must be specified

  Below is the command I’m using to compile the mp4 from the jpg :

  ffmpeg -r 25 -f image2 -s 1280x720 -i /data/camipjpg/%*.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p /data/camipmgpg/20190110.mp4

  For the sake of curiosity, I investigated and noticed that the camera actually has 2 modes (day and night). Images taken during the night have frames 1 while images taken on the "day" mode have frames 3.

  Is there a way ffmpeg can handle that kind of jpg changes to combine these different types of jpg ?

  Here is the output :

• Mozilla Firefox 36 has problems playing my h264 MP4 files

  11 juin 2015, par Wolfgang Pürstner

  I try to convert videos with ffmpeg to mp4 format (h264) Profile : High Level : 3.1 (1280x720 with 30fps), Bitrate 1500k

  The video plays very well in every browser except in Firefox.

  http://5.79.72.89/trailer/trailer.mp4

  At first it needs longer to load and when I seek inside the video most times the video don’t stop to load and never plays again.
  I can see a lot of partial downloads in the developer console. A lot of them are for the initial play and the rest of the requests are during the video load when I seek to a later position.

  

  When I play other h264 Videos (MP4 with similar settings) they play without problems on this server.
  And when I put my video on another webserver (apache) there are the same problems with Firefox.

  For this reason I believe it has to do something with me my conversion.

  My settings :
  Debian 7 (wheezy)
  Webserver : nginx (with 260k bandwidth limit)

  I started converting videos with avconv and switched to ffmpeg because of this problems. But there was no success.
  Meanwhile I tried all options for encoding but there are always the same problems with Firefox. Other videos play well but not mines and I don’t know why.

  Command :

  ffmpeg -i input.mp4 -tune zerolatency -x264opts bitrate=1500:vbv-maxrate=1500:vbv-bufsize=3000:nal-hrd=vbr -codec:v libx264 -profile:v high -level 3.1 -movflags +faststart -pix_fmt yuv420p  -s 1280x720 -r 30 -ac 2 -ar 48000 -codec:a aac -ab 64k -strict experimental -y trailer.mp4

  Update 2015-03-12 :

  If I convert the video without audio stream there is no problem with firefox anymore.

  I updated ffmpeg to 2.6. I used libfaac, aac and libfdk_aac for audio encoding with cbr and vbr but without success.
