• ffmpeg for android, out of memory on encoding h264

  15 juin 2018, par Rafael Lima

  I’m getting an weird error when enconding a video with ffmpeg on android

  Failed to inject frame into filter network: Out of memory

  Althoug is a pretty objective error, I do believe this is some "generic message" for another problem, because the video I used for testing is 17MB and less than 11 seconds length and I’ve sucessfully tested with videos bigger than 200MB and longer than 5min

  This problem happens to any video vertical videos recorded on my phone (the videos were recorded and play fine on my phone but i cant reencode them... other video h264 were encoded fine on same phone)

  this is ffmpeg output

  =====================UPDATE===================

  I re-run the command with -v 9 -loglevel 99 and got paste the log file at :

  https://pastebin.com/ihawsPvZ

  If someone have real good expertise at ffmpeg i would apreciate very much the help

  =====================UPDATE 2=================

  I made more tests and the problem happens only when i record the video with my phone at vertical (other videos in vertical work and videos from my phone in horizontal also work)

  ==================UPDATE 3====================
  I detected the problem happens to ANY video with the

  Metadata:
  
        rotate          : 90 (or any value)

  It was suggested to use -noautorotate as workaround and it WORKDED, but this implies in tons of other complications ex :

  -if i decide to apply any filter to the video, it will be applied to the horizontal version but the video will be played at vertical producing a totally different effect

  ex : https://i.stack.imgur.com/R3jXJ.jpg (at this photo the drawtext filter should be placed at bottom line with horizontal text, but as ffmpeg can’t handle the orientation it is missplaced and rotated at runtime producing this vertical message)

  -I checked and if I set -metadata:s:v:0 rotate= while enconding it has no effect ex :

  ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate= output.mp4
  will remove the rotate metadata and produce a non rotated video

  BUT
  ffmpeg -i input.mp4 -c:v libx264 -metadata:s:v:0 rotate= output.mp4
  will keep the metadata and the produced video will be played rotated (this behavior was also noticed on the official ffmpeg 4.0 binaries for windows available at ffmpeg website)

  I’M STILL LOOKING FOR A BETTER SOLUTION, THANKS FOR THE HELP

• ffmpeg Error initializing output stream 0:0 — Error while opening encoder for output stream

  23 juin 2018, par gufidown

  I am a newbie in terms of video processing in general and ffmpeg in particular. So this might be a real beginner’s question.

  I am trying to extract frames from an avi. This is the command :

  ffmpeg.exe -i 123.avi -vf select='gt(scene\,0.4)',scale=1920:-1,tile=6x3 -frames:v 1 456.jpg

  And this is the console output :

  Do I need a particular encoder when working with avi files ? Which one and how do I specify it ?
