• Copying GoPro metadata with ffmpeg - Could not find tag for codec none

  12 juin 2024, par TomMaier

  I am trying to use ffmpeg to copy the metadata of a gopro file.
The most basic demonstration of the problem would be to copy everything to a new file :

  


  ffmpeg -y -i source.MP4 -c copy -copy_unknown -map 0:v -map 0:a -map 0:2 -map 0:3 -map 0:4 -map_metadata 0 result.MP4


  


  This produces the error :

  


  Could not find tag for codec none in stream #2, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:4 --


  


  As I understand it this means that ffmpeg doesn't apply the -c copy operation correctly and instead complains that there is no encoder for the data streams. The same error happens for 0:2 and 0:4

  


  While searching on google if have found some people who have had the same issue in the past but I have also found some reports of it working.

  


  Any ideas what am I doing wrong or is this actually a bug ?

  


  Here is the ffprobe and the link to the GoPro file.

• Opus Audio Codec in Linphone Android 2013 Version

  2 septembre 2015, par Redturbo

  I want to just enabled Opus Audio Codec in my VOIP application, I have try code from here : http://stackoverflow.com/questions/31635522/force-using-just-opus-codec-in-linphone-android/31652551#31652551

  I try to check findpayloadtype first :

  for (PayloadType pt : mLc.getAudioCodecs()) {
  
                  pt = mLc.findPayloadType("PCMA", 8000, 1);
  
                  Log.d("LinphoneManager", "PayloadType PCMA : " + pt);
  
              }
  
  
  
              for (PayloadType pt : mLc.getAudioCodecs()) {
  
                  pt = mLc.findPayloadType("PCMU", 8000, 1);
  
                  Log.d("LinphoneManager","PayloadType PCMU : "+pt);
  
              }
  
  
  
              for (PayloadType pt : mLc.getAudioCodecs()) {
  
                  pt = mLc.findPayloadType("OPUS", 8000, 1);
  
                  Log.d("LinphoneManager","PayloadType P : "+pt);
  
  
  
              }

  PCMA and PCMU show value in log :

  [PCMA] clock [8000], bitrate [64000]

  [PCMU] clock [8000], bitrate [64000]

  but OPUS show null value :

  null

  is that something wrong with my code to got OPUS audio codec, or something else ?

• FFmpeg : Image sequence with ffv1 codec ?

  31 octobre 2014, par manu

  Is it possible to output an image sequence in ffmpeg using the ffv1 codec ?

  If so, in what container, how would I reimport these back into ffmpeg ?

  • movie containers seem not possible for seq output
  • i can force output -f image2 to any container, but import is not possible even with -c:v ffv1 as an input option.

  Encode of "intermediate.ffv1"

  ffmpeg -y -ss 250 -i "/media/pool/vrender_input/movie.mov" -vframes 1 -c:v ffv1 -compression_level none -map 0:0 -an -f image2 -threads 0 "/media/scratch/intermediate.ffv1"    

  Decode of "intermediate.ffv1"

  ffmpeg -y -c:v ffv1 -f image2 -i "/media/scratch/intermediate.ffv1" -c:v tiff -an -f image2 "/media/scratch/final.tif"

  Error :

  Whats wrong ?
