Add Cache data to Hard Drive,Preload data to Hard Drive #340
Description
Disk Cache & Preload Support for Better High-Bitrate / Poor-Network Playback Experience
Background
We are currently using fvp in Flutter to implement video playback.
When playing high-bitrate videos (e.g. Dolby, high frame rate, high bitrate streams) over the network, especially under unstable or poor network conditions, the player frequently enters buffering states. This results in noticeable stuttering, long waiting times, and an overall degraded playback experience.
Current Limitations
Playback mainly relies on in-memory or streaming-based buffering
High-bitrate videos continuously buffer under weak or unstable network conditions
Cached data is not persisted to disk, so previously downloaded data cannot be reused after app restart or page switching
There is no way to preload video data in advance to ensure smooth playback later
Expected Features
To improve playback experience, we would like to see support for the following capabilities:
Cache data to Hard Drive
-
Persist downloaded video data to local storage (hard drive)
-
Support cache reuse and resume playback from cached data (seek / resume)
Preload data to Hard Drive
-
Allow preloading a specific duration or size of video data to disk before playback or during idle time
-
Reduce initial startup latency (first frame delay) and re-buffering during playback
Questions
Is there already any plan or roadmap for these features?
Is there any preliminary design or technical direction for implementing disk caching / preloading?
If these features are not yet implemented or are currently under planning, I would be very happy to contribute to the development or help with the design and implementation.
Thank you for your work on maintaining the project!
