如何在Flutter中使用light_compressor包设置视频的特定最小比特率？

发布于 2025-01-15 05:05:43 字数 689 浏览 3 评论 0原文

我尝试使用 flutter 的 light_compressor 包来压缩我用手机拍摄或从 YouTube 下载的视频。

我参考下面的文章。 https://morioh.com/p/ac6f0d2c176b 本文中可以设置最小码率，默认值为2mbps。

但示例代码中只有isMinBitrateCheckEnabled标志，并没有设置具体码率的参数。

如何将视频压缩到我想要的比特率？

以下是示例代码的一部分。

import 'package:light_compressor/light_compressor.dart';


final LightCompressor _lightCompressor = LightCompressor();
final dynamic response = await _lightCompressor.compressVideo(
  path: _sourcePath,
  destinationPath: _destinationPath,
  videoQuality: VideoQuality.medium,
  isMinBitrateCheckEnabled: false,
  frameRate: 24 /* or ignore it */);

原文

I tried using flutter's light_compressor package to compress a video I shot with my phone or downloaded from YouTube.

I refer to the article below.
https://morioh.com/p/ac6f0d2c176b
In this article, the minimum bit rate can be set and the default value is 2mbps.

However, in the sample code, only the flag isMinBitrateCheckEnabled exists, and there is no parameter to set a specific bit rate.

How do I compress the video to my desired bitrate?

Below is a part of the sample code.

import 'package:light_compressor/light_compressor.dart';


final LightCompressor _lightCompressor = LightCompressor();
final dynamic response = await _lightCompressor.compressVideo(
  path: _sourcePath,
  destinationPath: _destinationPath,
  videoQuality: VideoQuality.medium,
  isMinBitrateCheckEnabled: false,
  frameRate: 24 /* or ignore it */);

该函数的架构是：

compressVideo(
  path,
  result,
  quality,
  isSharedStorage,
  isMinBitrateCheckEnabled,
  videoBitrateInMbps,
  disableAudio,
  keepOriginalResolution,
  videoHeight,
  videoWidth,
  saveAt,
  videoName
)

您可以通过 videoBitrateInMbps 属性设置比特率。希望这对您有帮助。

The schema for the function is:

compressVideo(
  path,
  result,
  quality,
  isSharedStorage,
  isMinBitrateCheckEnabled,
  videoBitrateInMbps,
  disableAudio,
  keepOriginalResolution,
  videoHeight,
  videoWidth,
  saveAt,
  videoName
)

You can set the bitrate through the videoBitrateInMbps attribute. Hope this helps you.
