• Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

  27 octobre 2015, par my name is

  Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
  This is the command I’m using :

  ffmpeg -y \
  
  -i "Robotica_1080.mkv" \
  
  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
  
  [v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull,asetpts=PTS-STARTPTS[aout1]; \
  
  [a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \
  
  -map "[out1]" "1.mp4" \
  
  -map "[out2]" "2.mp4" 

  1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

  I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360[vout1]; \
  
  [v2]scale=640:360[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull[aout1]; \
  
  [a2]anull[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \

  but still no audio on 2.mp4

  Can anyone give me a hint ?

  —EDIT—
  This is the output from first ffmpeg command :

• ffmpeg : unsync audio after processing

  18 novembre 2013, par QuickSilver

  I am recording a video and using RecordRTC : WebRTC . After receiving the webm video and wav audio at server, I'm encoding it to a mp4 file using ffmpeg(executing shell command via php). But after encoding process, the audio is unsync with video (audio ends before video). How can I fix this ?

  js code is here

  ffmpeg command used is :

  ffmpeg -y -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4

• Two nearly identical ffmpeg commands, one works, the other freezes up

  12 septembre 2019, par dylanjha

  In both of these examples, I’m passing two inputs to ffmpeg applying a filter to the first input, and outputting it all to a .mp4.

  Example 1

  ffmpeg -y -threads 4 -ss 23.536 -t 44.854 -i .tmp/processing/vid-one.webm -ss 13.516 -t 54.874 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-23536-68390.mp4

  Example 2

  ffmpeg -y -threads 4 -ss 68.39 -t 3.646 -i .tmp/processing/vid-one.webm -ss 58.37 -t 13.666 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-68390-72036.mp4

  In the logging output I can get an idea of where it gets hung up.

  Output Example 1

  the output gets to this frame= line and it updates the output like this
