• ffmpeg does not copy custom metadata

  20 juin 2015, par e110c0

  I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

  I tried a couple of versions, all with the same result, e.g. :

  ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

  This should work, it already gives the correct preview of metadata :

  I also tried to add the one tag I’m interested in by hand with

  -metadata:g location=+48.2683+007.7205+172.710/

  with no change in the result.

  Output as .mov doesn’t change anything, neither.

  Is there any trick to add non-standard metadata ? How do I get the location back in there ?

  Thanks in advance to anyone who can give some insight on this.

• streaming FLV to RTMP with FFMpeg using H264 codec and C++ API to flv.js

  5 février 2018, par Jan Kuri

  I would like to stream live video from webcam using OpenCV using H264 codec and converting that to FLV then stream over RTMP server and catch the stream in browser with flv.js.

  As I said before I can successfully open the stream with ffplay rtmp://localhost/live/stream or ffplay http://localhost:8000/live/stream.flv but I cannot open the stream with flv.js player inside browser with getting errors :

  flv: Invalid AVCDecoderConfigurationRecord, lack of data!
  
  [FLVDemuxer] > Malformed Nalus near timestamp 0, NaluSize > DataSize!
  
  [FLVDemuxer] > Malformed Nalus near timestamp 1, NaluSize > DataSize!
  
  [FLVDemuxer] > Malformed Nalus near timestamp 2, NaluSize > DataSize!
  
  ....

  I would really appreciate any help of fixing the stream to work properly with flv.js, if I stream video like ffmpeg -re -i input.mp4 -c copy -f flv rtmp://localhost/live/stream I can open stream in flv.js without any issues, so "this command" I would like to achieve inside code roughly.
  I also put my code on GitHub repository here if someone would like to compile the code and check on it.

• (osx) ffmpeg combining mp3 and png to mp4 resulting in mp4 with no audio

  18 juin 2016, par Ian H

  I’m writing a python script that uses unix commands to do some file conversions/renderings. I’m trying to join some mp3 files with png files to get mp4s that are the picture with the mp3 playing over them. However, I’ve tried this with lots of different codecs and settings, and the output mp4 video never seems to have audio in it. I’ve looked at any answer to any question even related to ffmpeg and haven’t found a solution.

  Some commands I’m trying to get working currently :

  ffmpeg -loop 1 -i slide_shot%d.png -i %s -c:v libx264 -pix_fmt yuv420p 
  
  -s 720x540 -t %.3f -c:a aac -b:a 192k -shortest out%d.mp4" 
  
  % (i, aud, slideTime, i)
  
  
  
  ffmpeg -loop 1 -i slide_shot%d.png -i %s -shortest -t %.3f -write_xing 
  
  0 -c:v libx264 -c:a libmp3lame -pix_fmt yuv420p -tune stillimage out%d.mp4" 
  
  % (i, aud, slideTime, i)
  
  
  
  ffmpeg -loop 1 -i slide_shot%d.png -i %s -shortest -t %.3f -write_xing 
  
  0 -c:v libx264 -c:a copy -pix_fmt yuv420p -tune stillimage out%d.mp4" 
  
  % (i, aud, slideTime, i)

  I’m currently using the third one. However, none of them are giving me any audio. For reference, i is a loop iterator for naming consistency, aud is the audio filepath, and slideTime is the number of seconds the video should take.

  Using this command, I’m currently getting this output in the Terminal :
