• How to deal with "[asf XX] too long payload" message in ffmpeg ?

  28 mars 2019, par Ayorus

  I am trying to cut a small section of a video using the following sentence :

  ffmpeg.exe -i video.wmv -ss 00:20:02 -to 00:20:09 -crf 22  "C:\test.mp4" -y

  However, ffmpeg hangs showing messages like :

  [asf @ 03327b00] too long payload 0kB time=00:00:00.00 bitrate=N/A speed=   0x
  
         Last message repeated 352 times 
  
  [asf @ 03327b00] too long payload 0kB time=00:00:00.00 bitrate=N/A speed=   0x
  
        Last message repeated 331 times

  I have waited for more than 30 minutes and ffmpeg did not finish the cutting. Does anyone have any idea how to solve this ?

  Any suggestion will be appreciated

  PD. the ffprobe output of the source file is the following :

• Using FFMPEG I get an error when trying to insert a fade after about 35 mins in a long video - is this possible ?

  8 avril 2019, par Matt Gardiner

  I have a source video that is an hour long from which I want to extract a couple of minutes towards the end and add a video fade in at the start of the cropped section.

  Using FFMPEG, I’m specifying the following command :

  ffmpeg -i MyLongVideo.mp4 -q:v 0 -y -ss 00:50:00.000 -to 00:52:00.000 -vf "fade=t=in:st=3000.0:d=1.0, scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:(1280-iw)/2:(720-ih)/2" ./testoutput.ts

  This is intended to crop from the source video from 50:00.000 to 52:00.00 and fade in from the 50th minute for 0.5 seconds (so at 3000 seconds in - st=3000.0).

  This command that we build programmatically, works on shorter videos or when you crop from before about 35 minutes. For this longer video though I get an error that says :

  [fade @ 0000025399981e80] Value 3000.000000 for parameter 'st' out of range [0 - 2147.48]

  The 2147.48 is around the 35 minutes in seconds which explains why this command works for shorter videos or on crops earlier than 35 minutes.

  I’ve seen a number of other issues with FFMPEG talking about this ’magic’ 2147.48 number with parameter values. Is this some sort of hard limit ?

  Is there a way to do what I want to do ? I could do this in two passes - extract the section of video and then add the fade, but I’d rather do it in one command if possible - and it works for shorter/earlier crops.

• How to set metadata year for a mp3 file and fetch it back in android ?

  6 mai 2019, par Aashit Shah

  I have been changing the metadata of input mp3 file and storing it in output all the metadata is successfully changing but the year metadata is getting as null.

  Below is my code.

  This is how I fetch the metadata in android :

       MediaMetadataRetriever mmr = new MediaMetadataRetriever();
  
                mmr.setDataSource(input);
  
                String Album = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUM);
  
                String Artist = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ARTIST);
  
                String Title = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_TITLE);
  
                String Composer = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_COMPOSER);
  
                String Genre = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_GENRE);
  
                String Year = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_YEAR);
  
                Log.e("date","date"+mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DATE));
