[Question] How to play video with start time?

[hezhong0711]

Is there any way to play video begin from a specific time like this command:
mpv --start=100 loadfile 'http://host/a.mp4' append

[cezres]

final Future<Duration> duration = player.streams.duration.first;
await player.open(Media(file.path), play: false);
await duration;
await player.seek(targetPosition);
await player.play();

cc @ethicnology.

There is still not a dedicated solution; but above shall work.

I adapted my UX to solve this need.
The video starts, If the user can resume, a resuming button that trigger the player.seek is displayed for a few seconds

final Future<Duration> duration = player.streams.duration.first;
await player.open(Media(file.path), play: false);
await duration;
await player.seek(targetPosition);
await player.play();

this doest work always

I've tried this:

await player.stream.buffer.first;
player.seek(targetPosition);

instead of await duration;, it works well for me every time

@alexmercerind plz include this as a core abilty

We can't just publish a feature if it works for some cases. We want it to work for every case & every backend (native & web) with appropriate unit-tests.

You are free to use the solutions provided here (which hopefully work). But if the package releases something "stable" it becomes our responsibility to ensure its functioning.

But I think there still should be a stable way to make sure the video is "load finished", means remote video source is available and we can freely do actions like seek. Maybe await controller.waitUntilFirstFrameRendered should do this, but it does not work with seek so far.

this needs to be a core ability because when we do it like this the ui lags behind because first it loads position at 0 and then change it

@alexmercerind plz include this as a core abilty

I recommend adding a initial time in the player.open function

@Prince-of-death Welcome to open source and free softwares where the scarce free time of developers is gifted to us

I recommend you start learning how to contribute to the codebase and implement this feature if it is so crucial for you, if not, you should work around the problem with one of the solutions offered above.

final Future<Duration> duration = player.streams.duration.first;
await player.open(Media(file.path), play: false);
await duration;
await player.seek(targetPosition);
await player.play();

I don't know if it worked before, but now (media_kit: ^1.1.10, media_kit_video: ^1.2.4, media_kit_libs_video: ^1.0.4) it doesn't work.
Because player.streams.duration.first; is always zero before the stream is loaded. And await player.stream.buffer.first; it is also always zero before the stream is loaded

For me, this solution worked

 await player.open(Media(file.path), play: false);
      controller.player.stream.duration.listen((event) async {
        if (event.inSeconds > 0){
          await player.seek(const Duration(seconds: targetPosition));
          await player.play();
        }
      });

I did implement this in the latest PR:

• feat: Media start & end #581

Thanks!
