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.

Rails ActionController::Live - Sends everything at once instead of async
28 janvier 2016, par Michael BI have an issue with rails
ActionController::LiveIn the end I want to show the progress of FFMPEG to the user, but for now I want to get this minimal example running :
Rails media_controller.rb :
class MediaController < ApplicationController
include ActionController::Live
def stream
puts "stream function loaded"
response.headers['Content-Type'] = 'text/event-stream'
i = 0
begin
response.stream.write "data: 1\n\n"
sleep 0.5
i += 1
puts "response... data: " + i.to_s
end while i < 10
response.stream.close
end
endJavascript :
source = new EventSource("/test/0");
source.addEventListener("message", function(response) {
// Do something with response.data
console.log('I have received a response from the server: ' + response);
}, false);When I navigate to the site, there are no JavaScript Errors showing. As soon as I navigate to the site, the "stream"-Action of the MediaController gets successfully called. I can verify this, by looking at the Server-Console. It gives me the following output. After every response line, there is a 500ms delay, like expected :
stream function loaded
response... data: 1
response... data: 2
response... data: 3
response... data: 4
response... data: 5
response... data: 6
response... data: 7
response... data: 8
response... data: 9
response... data: 10
Completed 200 OK in 5005ms (ActiveRecord: 0.8ms)On the JavaScript Side, it gives me the following Output :
(10x) I have received a response from the server: [object MessageEvent]But the problem is here, that it sends all these 10 Messages from the server after 5 seconds at the same time ! The expected behavior however is, that it should send me 1 message every 0.5 seconds !
So what am I doing wrong here ? Where is the error ?

Fast movie creation using MATLAB and ffmpeg
24 février 2018, par hyiltizI have some time series data that I would like to create into movies. The data could be 2D (about 500x10000) or 3D (500x500x10000). For 2D data, the movie frames are simply line plot using
plot, and for 3D data, we can usesurf,imagesc,contouretc. Then we create a video file using these frames in MATLAB, then compress the video file usingffmpeg.To do it fast, one would try not to render all the images to display, nor save the data to disk then read it back again during the process. Usually, one would use
getframeorVideoWriterto create movie in MATLAB, but they seem to easily get tricky if one tries not to display the figures to screen. Some even suggest plotting in hidden figures, then saving them as images to disk as.pngfiles, then compress them usingffmpeg(e.g. withx265encoder into.mp4). However, saving the output ofimagescin my iMac took 3.5s the first time, then 0.5s after. I also find it not fast enough to save so many files to disk only to askffmpegto read them again. One couldhardcopythe data as this suggests, but I am not sure whether it works regardless of the plotting method (e.g.plot,surfetc.), and how one would transfer data over toffmpegwith minimal disk access.This is similiar to this, but
immovieis too slow. This post 3 is similar, but advocates writing images to disk then reading them (slow IO).
