Server-Side Video Stream Conversion for Playback Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face difficulties in playing videos due to complex encoding and decoding scenarios, such as unsupported protocols, lack of decoding capabilities, and weak network environments, leading to poor video playback quality.
Innovation Solution
An information processing method involving a server that receives an initialization application from a client, acquires video stream data, converts it to a playable format, and provides it to the client for seamless playback, utilizing worker threads, cache regions, and encoding/decoding techniques like ffmpeg to handle various encoding formats and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If video stream data is directly played on the client, then playback speed is fast, but playback compatibility is poor due to unsupported protocols and lacking decoding capabilities
Solution Approach 1:
The patent introduces a server as an intermediary between the video source and the client. The server receives the video stream, performs decoding and re-encoding into formats compatible with the client's playback capabilities, then transmits the processed video to the client. This intermediary processing resolves the contradiction by maintaining fast playback through efficient server-side encoding while achieving broad compatibility through format conversion.
Solution Approach 2:
The patent replaces the client's mechanical decoding capabilities (which are limited by device hardware) with server-side software decoding using tools like ffmpeg. This substitution allows the server to handle complex decoding tasks that would be impossible or inefficient on the client device, thereby achieving both fast playback and broad format compatibility.
2Adaptability or versatility
If complex encoding and decoding is performed on the client, then video format compatibility is improved, but device performance requirements increase
Solution Approach 1:
The server acts as an intermediary that performs all complex encoding and decoding operations. By offloading these computationally intensive tasks from the client device to the server, the patent achieves broad video format compatibility through professional-grade encoding/decoding while keeping device performance requirements minimal.
Solution Approach 2:
The patent extracts the complex encoding and decoding functionality from the client device and relocates it to the server. This extraction removes the performance burden from the client while maintaining comprehensive format compatibility through the server's powerful processing capabilities.
3Manufacturing precision
If video is downloaded before playback, then playback quality is high, but waiting time increases
Solution Approach 1:
The server performs preliminary actions by pre-decoding and pre-encoding video streams into multiple format variants before the client requests playback. This preliminary preparation ensures that when the client requests video playback, the appropriate format is already ready for immediate transmission, achieving both high playback quality and minimal waiting time.
Solution Approach 2:
The patent implements dynamic video processing where the server adapts the video encoding format in real-time based on the client's capabilities and network conditions. This dynamic approach allows the system to optimize playback quality while minimizing waiting time by selecting and preparing the most appropriate format before transmission.
Data Source
AI summary
An information processing method and apparatus, an electronic device and a computer readable storage medium are provided. The information processing method includes: receiving a first initialization application from a first client and responding to the first initialization application, wherein the first initialization application includes a play parameter of video stream data playable on the first client; receiving a task instruction from the first client after responding to the first initialization application; acquiring first video stream data according to the task instruction; converting the first video stream data into second video stream data such that the second video stream data has the play parameter; and providing the second video stream data to the first client so that the second video stream data is played on the first client.
