• Remove Rotate metadata from mp4

  2 avril 2014, par mbajur

  I'm trying to remove or modify a rotate param from my mp4 file using ffmpeg. Based on some google results, i've ended up with such command (i've tried a few more but none of them worked) :

  $ ffmpeg -i ./source.mp4 -metadata rotate=0 ./output.mp4

  But it's not working at all. The rotate=270 metadata param is still there in the output file. Can you please advise me on how it should be done ?

  I'm using

• Ffmpeg : Audio/Video mixing but no sound

  14 janvier 2014, par user2914878

  The command i am using on a Debian distrib is this one

  ffmpeg -r 1 -i edit%0d.jpg outputName.mp4 -i Test.mp3

  The video file is created but the audio is not working .

  On Windows it is working fine, i tried multiple scenarios but i can't seem to find the issue, maybe a codec problem ?

  Thank you !

  Update :

  I manage to fix it this way :

  ffmpeg -r 1 -i edit%0d.jpg -i Test.mp3 -ar 44100 -strict experimental

• Stream webcam using ffmpeg/avconv to RTMP libx264 doesn't work

  15 mars 2016, par Erez Posner

  i have been trying to stream my webcam to Ustream using RTMP.

  using the standard command works great :

  "avconv -f video4linux2 -r 25 -s 320x240 -i /dev/video0 -f flv rtmp ://host/pass"

  but i encoutner a 15 seconds latency !
  therefore i decided to compress the video using libx264.
  i downloaded it and confirmed it is installed properly.
  but when running this command :

  "avconv -f video4linux2 -r 25 -s 320x240 -i /dev/video0 -c:v libx264 -pix_fmt yuv420p-f flv rtmp ://host/pass"

  on ffmpeg i get "Illegal instruction"
  and under avconv it starts to stream but nothing is shown in Ustream channel.
