La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

Cannot merge VisualSampleEntry error while appending videos in MP4parser
13 août 2021, par Abhishek IppakayalI am creating four videos with ffmpeg and then i am appending them with MP4parser.
Details of four videos that i am creating with ffmpeg.


- 

- 1,2 video : created using one image




[-loop, 1, -i, Count_1627453922.jpg, -s, 720x1280, -vf, format=yuv420p,fps=25,fade=type=in:duration=1,fade=type=out:duration=1:start_time=1, -t, 2, -preset, ultrafast, CountImageVideo_1627453922.mp4]


- 

- 3,4 video : trimming 3 second video from an existing mp4 video




[-i, footages_5_1624263519549.mp4, -ss, 00:00:00, -to, 00:00:02, -s, 720x1280, -r, 25, -preset, ultrafast, One_1627453926.mp4]


Now i am trying to append all these videos with MP4Parser and getting below error :


java.io.IOException: Cannot merge VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@f3f76444] and VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@e20a2ed0]
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.mergeStsds(AppendTrack.java:116)
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.<init>(AppendTrack.java:59)
</init>

I have done some debugging and found something that can help understand error better.
Sample Description boxes of two videos


Two video tracks have different formats (MP4v & AVC1). I am new to ffmpeg and MP4parser so did not getting what i am doing wrong. Thanks ! in advance.

Music Video Idiosyncrasies
18 juin 2011, par Multimedia Mike — GeneralSo I’m watching a fairly recent music video for a song named "XXXO" from an artist named M.I.A. when I’m suddenly assaulted by this imagery :
... and I enter nervous convulsions. You see, while this might seem to be an odd video effect to the casual viewer, to a multimedia hacker, it appears to be deliberately antagonistic. To anyone who has written a video codec, this scene looks like an entire casserole of video bugs, combining creeping plane offsets errors, chroma problems, and interlacing havoc. The craziest part is to realize that this is probably some kind of standard video effect / filter type. Upon a repeat viewing, I realized that the entire video sort of looks like an amateur video editor’s first week using video software.
Elsewhere in the video, a YouTube-style video frame vortex highlights the proceedings. I guess I need to come to terms with the fact that the ubiquitous player frame is just part of the digital Zeitgeist now :
Vintage Video Strangeness
I’m a long-time music video junkie but I have a tendency of examining them entirely too closely. I first saw Paula Abdul’s video for "Cold-Hearted" when I was just starting to understand multimedia technology and how it interacted with emerging home computers. Imagine how confused I was when I tried to make sense of the actions performed by our eMaestro "Chuck" whom Paula has instructed to "hit it". First, he hits a key followed by 3 quick strikes on a second key :
Then, the "start music" action is apparently bound to a particular key on the electronic keyboard :
Which kicks off the electronic metronome on the computer. Each identical-sounding beat quizzically maps to a different frequency transform :
a one...
and a two...
and a three...
I had no trouble believing things up to this point. But even though I didn’t understand what was going on with that frequency transform, I knew that it must have had something to do with the audio. And if the audio was the same, the visualization ought to be the same. Though, to be fair, I will concede that the first and third ticks pictured bear some mutual resemblance.
Anyway, the software is probably real even if the keyboard interaction was stylized. Can anyone identify the software ? What about the computer ? This is perhaps the best view the video gives us :
So, remember, don’t base your understanding of technology — or anything, really — on stylized media representations. Don’t even get me started on the movie "Sneakers." That had me confused about cryptography and computer security for many years.
