• FFmpeg playing multiple videos concurrently - mute/unmute

  21 avril 2014, par pris

  I have 3 videos (video1/video2/video3). I would like to play them on different time intervals :

  • video1 plays from 0-15s (video1 with sound, video2/video3 mute)
  • video2 plays from 15-21s (video2 with sound, video1/video3 mute)
  • video1 plays from 22-30s (video1 with sound, video2/video3 mute)
  • video3 plays from 31-40s (video3 with sound, video1/video2 mute)

  I have tried the following but only video1 has sound :

  ffmpeg -i video1.mp4 -i video2.mp4 -i video3.mp4 -i video4.mp4 -filter_complex "[0:v][1:v] overlay=0:0:enable='between(t,10,20)' [tmp]; [tmp][2:v] overlay=0:0:enable='between(t,30,40)' [tmp1]; [tmp1][3:v] overlay=0:0:enable='between(t,50,60)'" final.mp4

  Console output :

  Is there simplest way to cut mkv file on Linux ?

• How to convert Lagarith .avi videos to MP4 using WinFF

  24 avril 2014, par Moein

  I have a bunch of .avi videos encoded with Lagarith codec. We would like to convert them in to a lossless .MP4 format so that they could be easily played on html. I want to keep video specifications remain the same if it’s possible and just convert the video to MP4.

  I tried WinFF and also some manually written FFmpeg codes [without any specific reference to the Lagarith codec] but they all create a video which is not playable (neither with Windows Player nor with the HTML5 player). Also, FFmpeg returns exceptions like bellow.

  Edit :
  Here is the FFmpeg code generated by WinFF, this code gives me the following Exception :

  "C:\Program Files\WinFF\ffmpeg.exe" -y -i "C:\Desktop\Videos\input.avi" -f mp4 -r 29.97 -vcodec libx264 -preset slow -vf scale=640:480 -b:v 1000k -aspect 4:3 -flags +loop -cmp chroma -b:v 1250k -maxrate 1500k -bufsize 4M -bt 256k -refs 1 -bf 3 -coder 1 -me_method umh -me_range 16 -subq 7 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec libvo_aacenc -b:a 112k -ar 48000 -ac 2 "C:\Desktop\Videos\output.mp4"
