I must clarify that I refrain from engaging with NSFW content. However, if the issues are prevalent on macOS and iOS, it's likely related to the media_kit. Have you tested it on iOS without using media_kit? It's also worth noting that the web version uses HLS, which relies on a dedicated JavaScript library.

Please note, I've removed the links related to NSFW content from the repository. My apologies, but I believe it's important to maintain a professional standard.

if you can provide another example in which its not nsfw, i would try to help you

Q: Have you tested it on iOS without using media_kit A: Yes , macos 13 and [ios Simulator] will error when drag the progress bar to an unbuffered position

[abdelaziz-mahdy]

thank you for providing a url which is safe for work

will try and let you know (most probably at weekend)

also can you show the logs

[abdelaziz-mahdy]

Also I think it may be the logic of separating the m3u8 to qualities is the one causing the problem

But further testing will make me sure

[log] {"timestamp":"2023-08-15T09:43:38.181611Z","level":"error","prefix":"ffmpeg","message":"NULL: missing picture in access unit with size 552"}

[log] {"timestamp":"2023-08-15T09:43:38.182093Z","level":"error","prefix":"ffmpeg","message":"NULL: missing picture in access unit with size 2516"}

[flutter_meedu_videoplayer] in macos , will print some this Warning log. I don't know if these are helpful ,

[abdelaziz-mahdy]

I can add an option to disable logs

But from what I see from these that ffpmeg can't access the position of which you need 😢

Anyway I will need sometesting to make it work, can you try media_kit and see if it happens and if it does open an issuer on their repo ?
