Hi I'm using the flutter video player plugin, I have something similar like this [{phrase:"something", startAt: 1039}, {phrase:"other something", startAt: 26500}] is there a way to change in ui the phrase based on the start time while the video is playing.
I have try to use a timer with a duration of 100 ms and use a player controller reference playerController.value.position.inMilliseconds and find if a phrase start at this time to scroll to this but it didn't work.
How I can't do that?
I tested the video plugin and I suggest you do the time comparison in seconds instead of milliseconds.
If you add a listener to your video plugin, unfortunately it won´t listen to it every millisecond, but it won´t fail the seconds count

I am using the camera package to record video in my app, via the
CameraController.startVideoRecording() method.
I would like to display the increasing value for the length of the video while recording.
My initial thought was to create a timer. But, I wonder if there is a better solution that is more integrated with the video recording itself, such a a callback/event that I can listen to for the current length of the video or some property related to the video that I can interrogate?
Any suggestions/recommendations or examples are appreciated.
Thanks
I have created the video player using chewie controller and I need to get the total watch or played time of video for the particular user and I need to update it in database. how can I achieve this?
Use value and position in the video controller .
what I'd like to do:
I would like to record a video using Flutter's CameraController that has the same duration as an animated webp. On top of my screen, the animated webp is playing and below there is a CameraPreview() widget that records whatever my camera catches. This recorded video's duration should be exact as long as the animated webp's duration.
what I've tried so far:
Since Giphy offers not only a webp-version, but also an mp4-version, I downloaded the mp4 version and used ffmpeg to get the duration of that file.
I then used a timer and called VideoController.stopVideoRecording() after this duration automatically after VideoController.startVideoRecording().
what I'd expect to happen:
I'd expect this recorded video to be as long as the animated webp. Unfortunately, it's not.
So, my question is:
Do you guys have any idea how I could manage to record a video with same duration as an animated webp?
Thanks :)
Ok, sort of found what the issue is: Webp (and also Gifs) in Flutter are played slower than in browsers. Dont know if that is the case for all webps and gifs, but the ones I tested are all animated faster in a desktop-browser than in flutter. So, animation time of those webp is not the same as playing-time of the respective .mp4 file.
I use those mp4-versions now instead and that does the job.
What is the correct way to begin playback of a video from a specific time?
Currently, the approach we use is to check at an interval whether it's possible to seek via currentTime and then seek. The problem with this is, when the video fullscreen view pops up, it begins playback from the beginning for up to a second before seeking.
I've tried events such as onloadmetadata and canplay, but those seem to happen too early.
Added information:
It seems the very best I can do is to set a timer that tries to set currentTime repeatedly as soon as play() is called, however, this is not immediate enough. The video loads from the beginning, and after about a second, depending on the device, jumps. This is a problem for me as it provides an unsatisfactory experience to the user.
It seems like there can be no solution which does better, but I'm trying to see if there is either:
a) something clever/undocumented which I have missed which allows you to either seek before loading or otherwise indicate that the video needs to start not from 00:00 but from an arbitrary point
b) something clever which allows you to hide the video while it's playing and not display it until it has seeked (So you would see a longer delay on the phone before the fullscreen video window pops up, but it would start immediately where I need it to instead of seeking)
do something like this;
var video = document.getElementsById("video");
video.currentTime = starttimeoffset;
more Information can be found on this page dedicated to video time offset howtos
For desktop browser Chrome/Safari, you can append #t=starttimeoffsetinseconds to your video src url to make it start from certain position.
For iOS device, the best we can do is to listen for the timeupdated event, and do the seek in there. I guess this is the same as your original approach of using a timer.

I am developing an application in that I want to play two video at the same time, That is not possible using MPMoviePlayer. So I have used AVQueuePlayer To play video. As I am success to play video but the problem is in jumping to particular time. For that we have method call seekToTime and we need to variable of the CMTime datatype.
I am able to jump at time in 1,2,3 seconds etc, My problem that I want to jump at Time 1.2, 1.3 , 1.4 second etc. but I am not able to move the video at that time.
Can any one know the solution of this problem than please help me to solve the problem.
The seekToTime: method, however, is tuned for performance rather than precision. If you need to move the playhead precisely, instead you use seekToTime:toleranceBefore:toleranceAfter Reference
toleranceBefore: The accuracy of the time before to which you would like to move the playback cursor.
[time-beforeTolerance]
toleranceAfter: The accuracy of the time after to which you would like to move the playback cursor.
[time+afterTolerance]
Lets say both parameters represents the margin of in-accuracy.
I have seen other Question on SO using self.player.currentItem.asset.duration to get the duration.
Good Luck.
