• 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.

• How to config FFmpeg for xrgb and Aver Media capture card [closed]

  12 mai 2023, par Plotter Desalor

  I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

  


  My capture card is named "Live Gamer Ultra-Video"

  


  In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

  


  Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

  "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

  


  But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

  How could I use rgb format with this capture card ?

  


  If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.

  


• How to fix video in gallery from not playing (probable cause encoding from ffmpeg)

  30 avril 2020, par Nathan Sinclair

  I'm setting up a video stream by which I can download a video into the Android gallery, so that I can play it back later.
I have a problem with playing the video back from gallery. The same problem arises when trying to view the url in a videoview.

  I have attempted to follow this article. Android MediaPlayer error (1, -2147483648)

  



  I'm using FFMpeg to record from a mjpeg stream into a file, which then is hosted by a uwsgi/flask server into a convenient url : http://ipaddress/video.mp4

  



  Thus far ive been able to open the video fine using chrome in Android.

  



  my FFMPEG command looks like this :

  



  ffmpeg -i $1 -crf 18 -r 30 -vf "scale=720x406, setpts='1/(30*TB) * (N + 0.05 * sin(N*2*PI/25))', fps=fps=30" -profile:v baseline -pix_fmt yuv420p -f mp4 -preset fast out.mp4


  



  I thought it may have something to do with the transmission of the file. I'm using an android library called volley to send the url so it can be downloaded as a file on the Android. Then it is subsequently put in gallery. This is when I began to experience the problems. I wanted to be thorough, so tried to find out if the file contents was the issue. This is because when displaying it on gallery, there is no width or height information, or even duration. I have come to suspect something is at issue with ffmpeg. I'm not cutting out that it could be keeping the file from opening if it can't find it's normal file properties.

  



  The volley code for the downloaded file is as follows :

  



   @Override
    public void onResponse(byte[] response) {
        try {
            if (response!=null) {

                File file = createVideoFile();

                FileOutputStream stream = new FileOutputStream(file);
                try {
                    stream.write(response);
                } finally {
                    stream.close();
                }

                addToGallery(file.getAbsolutePath());
                MediaScannerConnection.scanFile(this, new String[]{file.getAbsolutePath()}, null, (path, uri) -> {
                    Intent intent = new Intent (context, VideoActivity.class);
                    intent.setData(uri);
                    startActivity(intent);

                });


                Toast.makeText(this, "Download complete.", Toast.LENGTH_LONG).show();
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            Log.d("KEY_ERROR", "UNABLE TO DOWNLOAD FILE");
            e.printStackTrace();
        }
    }

private void addToGallery(String path) throws FileNotFoundException {
        MediaScannerConnection.scanFile(context, new String[]{

                        path},
