• Merging audio at specific time with ffmpeg

  19 octobre 2015, par Deepu

  I was trying to merge audio with ffmpeg with the following command but the audio is merging at starting point.

  ffmpeg -i output-1146.mp4 -i org-EOLWAudio.mp3 -filter_complex " [0:a]atrim=start=0,asetpts=PTS-STARTPTS[aud1]; [1:a]atrim=0:250,asetpts=PTS+100/TB[aud2]; [aud1][aud2]amix=inputs=2[aout]" -map 0:v -map "[aout]" -crf 24 -pix_fmt yuv420p -c:v libx264 -c:a aac -strict -2 -ac 2 output-1246.mp4

  With this command it is merging audio streams but not specified point of time.

  I want to merge audio of a mp3 file from 0 to 250 seconds audio to video
  Starting at 4th minute to 8.10 minute.

  Output :

  As you can see,original video "Duration : 00:00:21.02",but the output file only "Duration 00:00:00.03".And the program exit no error.

  It didn’t convert entire file.

  What args I need to add ?

• error when converting mts to mp4

  6 janvier 2015, par Chan Kim

  I have many video files that I want to convert to mp4.
  so I installed ffmpeg on my win7 PC (64 bit) which is using shared library.
  I tried to convert an MTS file to MP4 and I get this error.
  What is the problem ?

  Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

  EDIT : I thought I solved this problem by using

  ffmpeg -i filename1.mts filename1.mkv

  my Samsung LED TV supports mkv file and during the conversion, it shows

    Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
  
    Stream #0:1 -> #0:1 (ac3 (native) -> vorbis (libvorbis))

  But Alas ! my TV doesn’t support vorbis codec. It only supports mp3, ac3, lpcm, and ADPCM when using mkv container. So the question is : How do people select output audio codec ?
