Video lag and stream interruptions on Android TV devices & Adding function subtitles and audio

[azulmouad]

Hello, I’m experiencing issues with your package. The video works well on mobile devices, but when I launch the app on Android TV devices, it lags and the stream videos stop and start. This issue is only present on Android TV, and I’m not sure why. Could it be because the player is not optimized for big screens?

Also, I have a request. Is it possible to add a function for subtitles and audio? I’m using stream video formats m3u8, and the URL has multiple subtitles and audios. Would it be possible to use your player for this?

I'm kind of confused by the word lag now, is it:

• Jank in Flutter UI.
• Pauses due to buffering e.g. due to slow internet.
• Overall slowness or less frame-rate in video playback.

Adding function subtitles and audio.

Read documentation carefully & search there.

When using the app on Android devices, the video experiences lag and buffering issues. Despite having a fast internet connection, the video plays smoothly on mobile devices, but the same content encounters problems when played on a television.

In your document, I discovered instructions on manually adding subtitles through a URL. However, on our end, we don't provide separate subtitle URLs; subtitles are embedded within the M3U8 or .MKV video URLs. When using VLC Player, it automatically decodes subtitles from the URL. I'm interested in knowing if your package provides a similar feature.

Hey AnyUpdates ?

the lag in Android TV is a frame drop due to the use of flutter framework, i have used native bridge to solve the problem with a native player (i used amazon exoplayer) with custom ffmpeg module to support audio decode. I have tried soo many different pack to solve the problem but only native implementation solve this

If everything is satisfactory for you, could you please share the project on GitHub? It would greatly assist us, as we are still encountering these issues. Thank you very much.

Any update for this post? I met the same issue with author and don't have any solutions for it. @alexmercerind ?

[alexmercerind]

Sorry no updates from my end. I don't have Android TV.

[adam-hoang-vn]

How about you? @azulmouad Do you have the solution for this issue?

I am using media-kit on Android TV and there is considerable frame loss. I will swap out with another player to isolate.

Hi, I'm trying to play FullHD video on my Android TV box but the performance is very slow. The video is glitchy and plays at about 10 fps. In addition, the media.codec loads the cpu at 100%.
PID USER PR NI VIRT RES SHR S[%CPU] %MEM TIME+ ARGS
438 mediacodec 20 0 188M 68M 62M S 98.3 3.3 52:53.81 media.codec hw/android.hardware.media.omx@1.0-service

@jeremylcarter @bl1nch could you please try to initialize VideoController with one of these configurations?

const configuration = VideoControllerConfiguration(vo: 'mediacodec_embed', hwdec: 'mediacodec');
OR
const configuration = VideoControllerConfiguration(vo: 'gpu', hwdec: 'mediacodec');

videoController = VideoController(player, configuration: configuration);

[jeremylcarter]

The video lag has gone with const configuration = VideoControllerConfiguration(vo: 'gpu', hwdec: 'mediacodec'); on Android TV but now the audio is not playing. Ill get the exact codec information and post it.

[jeremylcarter]

Very strange the codec is AC3, so perhaps passthrough is not working?

If the Audio not playing try to test the app in a real device. i faced the same issues using Simulator .

I can give an example of buffering issues or lack of being able to configure buffers...
https://mp3.sunsaturn.com/dog.mkv

Try loading that in video player and can see buffering issues...

Needs a way to buffer a bunch ahead of time, before playing...

I'm just donating some bandwidth off my dedicated server in Kansas City for developers to test with. For a true test you want a good quality mkv as other formats are generally inferior and you could download them faster negating the pre-buffer test. If mediakit can stream that file without problems, then I envision no other users will have any other problems regarding this issue.

It's only a 11gig file, not typical 20 gig 4k. Server will support CORS bypass for your testing.

I'm still encountering problems with video playback on the web. When I try to play the video, I only see a black screen. The video URL works fine on mobile and desktop platforms, but it seems to be incompatible with web browsers

web support is limited as mentioned here

I am actually wondering if you can install audio/video codecs on windows 11, whether web would then work as it uses native backend? If that doesn't work, maybe an addon to chrome for codec
