The IP Camera stores an mp4 type container. but my customer want me to change the type from *.mp4 to *.mov.
I trying to convert from mp4's container to *.mov's container a video in the
IP Camera.
Can anyone tell me the exact way to change the container of mov from container of mp4 ?

I want to render a video file using some images with animation.
I have tried some solution out there and i did not get any solution either I don't know how to write command of FFmpegKit. I also tried to first implement a single image with mp3 but it was also not working.
i want to extract MKV container's (audio and video) in to mp4 container and after that play it in AV-player
is it possible? and how?
i m tiered to searching about thatš©
I would like to generate video content from text/images with provided content size. Have tried many options from FFmpeg to h264 encoders. So a want to build a solution that takes one image or array of images and generate video stream, let's say rtmp. Also image is always changing, adding text, change color etc. I have tried with Golang.
I have implemented a app to capture image from camera and convert it to pdf and share that image.But I want to display camera captured image like on camscanner image using image processing, Can anyone suggest to dart library to do my task?
I have found a suitable answer for my requirement. I have used "edge_detection 1.0.5" package for detect edges for capture image so then final output will same as camscanner output.

Iām working on a Matlab application that uses a VLC class to control a VLC-instance. One of the features is to set the VLC player to fullscreen. This feature works perfectly fine.
The VLC player is downloaded from Matlabās File Exchange: https://se.mathworks.com/matlabcentral/fileexchange/56215-vlc (Thanks a lot LĆ©a Strobino)
However, one particular clip insists on resizing the player to a smaller size.
I have done some research and it turns out that this is a common problem in some VLC versions.
Normal workarounds are to uncheck the āadapt interface to video sizeā (something like that) and to check the āFullscreenā box.
This ought to make the player open in fullscreen and not resize the screen to video size. The video still resizes the player to a smaller size.
All the specs of the clips are the same: Same file extension (.vob), formats and were made the same way (I did some video trimming and such using ffmpeg ā but the same way every time).
I have noticed one difference and that is that this particular video has a lower Data and bitrate (~1000-1500kbps) where as the others are higher (<4000kbps). Also when showing the properties of the clip the frame height and width are blank as opposed to the others that have specific values.
This should however not have an effect of the fullscreen command from Matlab called after loading the video into the playlist. The command has no effect on this video, but does on all other.
It is possible to set the player to fullscreen manually by clicking the window, so it is not caused by some restriction in the video not allowing it to fullscreen.
Why does the video refuse to go in to fullscreen?
Hope somebody is able to help.
Okay so I seem to have solved the problem now. Without being completely sure why - the problem was in the lowered data/framerate.
I tried to add -crf 18 when converting my .mp4 to a .vob file:
ffmpeg -i input.mp4 -vcodec copy -acodec ac3 -crf 18 output.vob
The -crf stands for Constant Rate Factor and is a way to ensure a specific Data rate. The values goes from 0-51 and 18 seems to be the lowest 'sane' value (highest data rate). A good explanation can be found here: https://superuser.com/questions/677576/what-is-crf-used-for-in-ffmpeg
With this higher data rate the video opens up in fullscreen everytime :=)
