• FFMPEG overlay issue for 2 videos, sound missing from second input

  7 septembre 2014, par Abhishek Singh

  I’m trying to achive an overlay with ffmpeg wich take the two flv files as input and make a output and both videos playing simultaneously. things are working fine with below ffmpeg command :

  ffmpeg -i input1.flv -vf "[in] scale=359:320, pad=2*iw+6:ih [left]; movie=input2.flv, scale=359:320 [right]; [left][right] overlay=365:0 [out]" -b:v 3600k -y output.flv

  But issue is with the sound of second video and that is missing from the output.flv, only input1 sound is available in the output.flv.

  Console output is :

• Converting Video for Android using FFMPEG

  13 février 2017, par Jebu

  What i am trying to do is convert video into mp4 format that will play in Android.

  I’ve gone through http://developer.android.com/guide/appendix/media-formats.html

  I am setting the following options

  -vcodec libx264 -vprofile baseline -acodec libfaac -ar 44100 -ac 1 -ab 128k yet I get the error message "Sorry, This Video is not valid for streaming to this device"

  I Played the video in android browser using videoJS http://video-js.zencoder.com/oceans-clip.mp4 and it WORKS fine.

  I download the video oceans-clip.mp4 and tried to convert using minimalist options

  -y -i working.mp4 -vprofile baseline pleasework.mp4

  yet I get the same error message.

  The following is the FFMPEG info dump of the video files

  Working.mp4

  The metadata looks almost the same yet it doesn’t seem to play in android. Any help appreciated.

• Rails : Encoder error when converting video using FFMPEG on Heroku

  2 janvier 2013, par andmcgregor

  I'm trying to upload a video and convert the file to mp4 and reduce the file size using the paperclip-ffmpeg and paperclip gems. Everything works fine running a local server and I'm only getting this problem on heroku. I have ffmpeg installed in vendor/ffmpeg/ (I followed these steps : https://gist.github.com/3963576). Here is the code I've got and the error I'm getting :

  models/video.rb :
