[alexmercerind]

Emulator?

[Generalomosco]

Real device on Redmi Note 11s

[alexmercerind]

I happen to have a Redmi Note 10S, can't experience the same.

[alexmercerind]

There shouldn't be D/AudioTrack logs... we only use OpenSL ES for audio.

Can you try disabling the audio (if it fixes the lag):

player.setAudioTrack(AudioTrack.no());

[alexmercerind]

I may go to sleep. It's 2:00 AM here, I will appreciate quick replies (or you have to wait for 8-10 hours).

[Generalomosco]

Still same thing even disabling the audio

[alexmercerind]

How does passing enableHardwareAcceleration: false in VideoController constructor do?

[alexmercerind]

Also... How does mpv perform on your device?

https://play.google.com/store/apps/details?id=is.xyz.mpv

[Generalomosco]

Also... How does mpv perform on your device?

https://play.google.com/store/apps/details?id=is.xyz.mpv

It plays perfect with the app

[Generalomosco]

Still lagging but no more logs when disabled

[Generalomosco]

This is the video i'm testing it with https://codeuplifts.com/static/NaturePortrait.mp4 but still same with other videos with high dimensions.

With mpv app on playstore sometimes it still stop and continue once or twice, but not that worse as mine. i have fast network

[alexmercerind]

I'm unable to play that MRL in Google Chrome as well. The connection speed seems to be very slow, which seems like the actual issue. Be assured that the performance of package:media_kit is very good on all platforms. Although I'm not denying the presence of any problem which I'm not aware of.

[alexmercerind]

I fetched & downloaded the video; I can't seem to experience lag of any kind on my Redmi Note 10S with G95.

[ScorpiosCrux]

I am experiencing a similar issue using this link . (Downloaded and played with media_kit package)

• I have tried playing the file locally with mpv from the play store and it plays really well.
• Hardware Acceleration is turned on, but actually plays better with it turned off.
• Turned off audio and same issue.
• Using --profile flag
• README.md code

Any ideas on what could be wrong?

Here is what the console shows:

Hi @ScorpiosCrux, thanks for joining in.

Behavior varies on different devices at times, especially in hardware decoding.

Can you try these configurations on your device? The first one seems to be default in mpv; but I experienced crashes.

configuration: const VideoControllerConfiguration(
  vo: 'gpu',
  hwdec: 'mediacodec',
),

configuration: const VideoControllerConfiguration(
  vo: 'mediacodec_embed',
  hwdec: 'mediacodec',
),

[alexmercerind]

Also:

• What processor does your device have?
• Is only this specific URL/media showing the lag?

[ScorpiosCrux]

Hello, I have added

configuration: const VideoControllerConfiguration(
  vo: 'mediacodec_embed',
  hwdec: 'mediacodec',
),

and now the video is playing very smoothly with no more than 10% CPU usage.

Thanks for the help!

[alexmercerind]

--vo=mediacodec_embed is very (very-very) efficient; beats-off anything that exists for Android.

While this happens to work on your device, it may yield a crash on some (older or low-end) devices. An approach for package:media_kit can be to select configurations based on the device chipset (select the most efficient where it's safe). This process will obviously rely upon reports from the users.

I am back with an update.

I am testing the code on 2 devices:

1. H96 Max v58 with: RK3588 quad-core Cortex-A76 and quad-core Cortex-A55
2. Orange Pi 5 with: Rockchip RK3588S 8-core 64-bit processor

Two issues:

• The MPV player with the same code plays well with no frame drops on the first one. But drops a frame per ~10 frames.
• The MPV player is not displaying true 4k resolution.
  • I tested this by playing a text file that display clearly with the built in player and comparing it to the mpv player and the media_kit player.

What I have tried:

  ... const VideoControllerConfiguration( vo: "gpu", hwdec: "rkmpp", width: 3840, height: 2160, enableHardwareAcceleration: true);
  ... const VideoControllerConfiguration( vo: "mediacodec_embed", hwdec: "mediacodec", width: 3840, height: 2160, enableHardwareAcceleration: true);

Any suggestions? Also, you mentioned you tested it with 8K 60 FPS, do you know what hardware you tested it on?

[alexmercerind]

I suppose it's not related to hardware problem (this issue is actually opened for it), then.

8K 60FPS is actually heavy for any mobile chipset.

[alexmercerind]

Natively, Android has that android.view.SurfaceHolder which dynamically sets the render surface size based on the "mount" size.

But, here in Flutter I manually set the render surface size using android.graphics.SurfaceTexture.setDefaultBufferSize based on video resolution.

You mentioned you tested 8K 60FPS on some hardware, what hardware did you use?

[alexmercerind]

My good ol' Redmi Note 10S with G95.

Hi @ScorpiosCrux, thanks for joining in.

Behavior varies on different devices at times, especially in hardware decoding.

Can you try these configurations on your device? The first one seems to be default in mpv; but I experienced crashes.

configuration: const VideoControllerConfiguration(
  vo: 'gpu',
  hwdec: 'mediacodec',
),

configuration: const VideoControllerConfiguration(
  vo: 'mediacodec_embed',
  hwdec: 'mediacodec',
),

Is there any similar configuration for macos and windows? it's lagging in macos and windows.

[alexmercerind]

What's your video resolution & hardware specification?

[BulbulRathore]

@alexmercerind In my application I have allowed upto 5MB and the video I uploaded is 814KB and also it's lagging if I upload and play audio file (52kb) mainly it's lagging when I play 3-4 audio or video files then the application completely stuck

[alexmercerind2]

Have you added media_kit_native_event_loop?

I won't be able to help out with just remarks like these. package:media_kit outperforms Google Chrome if we talk raw performance. Share logs, sample files, platform, specs or at-least the video resolution.

[alexmercerind2]

Make sure you dispose Players correctly too.

[BulbulRathore]

I am not getting any error logs. will share sample files. disposing Player correctly but I didn't added media_kit_native_event_loop. will add this.

[alexmercerind]

A stable version has been rolled out. A number of major enhancements.

Please refer to the "Installation" section of the README to receive the update.

Now direct mediacodec is used on Android, which will greatly enhance the performance. The stability has also been improved.

@BulbulRathore

The current video playback performance is comparable to that in Chromium/Google-Chrome on Windows. This is the performance on my 350$ laptop having entry-level Ryzen 3 2200U with integrated Radeon Vega 3 graphics. It should be better on a more capable GPU/CPU.

Check your video drivers or the presence of media_kit_native_event_loop, which adds support for more simultaneous videos.
