遇到伪装图片的视频，没有触发异常或事件通知

[yemin82]

调试后再 /fvp-0.25.0/lib/src/player.dart final size = await _videoSize.future; 这这个位置就不会往下走了，系统能提供异常或事件

测试视频 https://yundunm3.czys.art:88/vtt/gc02/sifangguan/sifangguan01.m3u8

[yemin82]

前面有字打错了，就是不用抛异常或事件通知

[wang-bin]

试下master分支，会有错误事件产生

[yemin82]

已经可以收到通知了，但是收到8次一样的通知，我不知道是不是遇到这个错误mdk重试了8次，这样就不好处理了，如果遇到一个通知的时候我就处理那么，浪费了mdk的7次重试次数，如果我等8次再处理，那么可能有的异常只重试了3次，结果苦苦等待也等等不来8次，是否可以在重试的最后一次再事件通知

你发下日志，我这边正常

内容太多分2次发的，。invalid or unsupported media收到了很多次

[wang-bin]

你发我个测试代码

[yemin82]

我重新测试了下我的代码也有问题，不过现在还是触发了2次 import 'package:flutter/material.dart'; import 'package:flutter/widgets.dart'; import 'package:fvp/fvp.dart'; import 'package:video_player/video_player.dart';

class TestPage extends StatelessWidget { const TestPage({super.key});

@override Widget build(BuildContext context) { registerWith(); var a = VideoPlayerController.networkUrl(Uri.parse( "https://yundunm3.czys.art:88/vtt/gc02/sifangguan/sifangguan01.m3u8")); a.addListener(() { if(a.value.hasError){ print("===${a.value.errorDescription}"); } }); print("====start"); return VideoPlayer(a..initialize()); } }

-========结果======= Restarted application in 531ms. flutter: ====start [2](flutter: ===invalid or unsupported media)

[wang-bin]

把两次value打印出来，区别是报错那次isCompleted是false，后面一次isCompleted是true表示播放结束，错误信息还是保留着，要不你判断下isCompleted

flutter: ===VideoPlayerValue(duration: 0:00:00.000000, size: Size(0.0, 0.0), position: 0:00:00.000000, caption: Caption(number: 0, start: 0:00:00.000000, end: 0:00:00.000000, text: ), captionOffset: 0:00:00.000000, buffered: [], isInitialized: false, isPlaying: false, isLooping: false, isBuffering: false, volume: 1.0, playbackSpeed: 1.0, errorDescription: bad video size, invalid or unsupported media, isCompleted: false),
flutter: ===VideoPlayerValue(duration: 0:00:00.000000, size: Size(0.0, 0.0), position: 0:00:00.000000, caption: Caption(number: 0, start: 0:00:00.000000, end: 0:00:00.000000, text: ), captionOffset: 0:00:00.000000, buffered: [], isInitialized: false, isPlaying: false, isLooping: false, isBuffering: false, volume: 1.0, playbackSpeed: 1.0, errorDescription: bad video size, invalid or unsupported media, isCompleted: true),

[yemin82]

明白了感谢

[wang-bin]

相当于播放过程中出现错误了，看video_player源码value是个成员变量，在播放结束的时候只是把iscompleted设true了，所以这现象符合预期

[yemin82]

发现新的问题，这个视频都是无法播放的，不应该用事件通知，目前initialize没有异常可以继续后续流程且isInitialized=true，有点不合理

[yemin82]

我直接用initialize后的size来判断了，其实这里做异常就比较合理

[wang-bin]

试下master最新代码

[yemin82]

很完美这样就和官方一致了

[wang-bin]

支持这类视频的ffmpeg已经有小伙伴编译出来了，可以在这下载 https://github.com/Predidit/avbuild/actions/runs/10561529946

替换相应的ffmpeg动态就行

[yemin82]

感谢，我等会试试看，那他这种可以播放你说的那种带封面的mkv么？

[wang-bin]

jpeg封面支持，png没了

[yemin82]

支持这类视频的ffmpeg已经有小伙伴编译出来了，可以在这下载 https://github.com/Predidit/avbuild/actions/runs/10561529946

替换相应的ffmpeg动态就行

还有就是ffmpeg下载的地方 lite和lite-lto的区别是什么

[yemin82]

只有在ios-arm64_x86_64-maccatalyst里面找到了 libffmpeg.7.dylib，这个文件夹应该是用于maccatalyst，ios真机和模拟器文件夹下没有 libffmpeg.7.dylib

[wang-bin]

还有就是ffmpeg下载的地方 lite和lite-lto的区别是什么

lto是有更多优化的，一般用lto版本就行

ios、tvos, xros和macos不一样，只能用framework不能用dylib。下载ffmpeg-master-iOS-lite-lto后把里面的ffmpeg-master-iOS-lite-lto-shared.tar.xz解压出来，进入ffmpeg-master-iOS-lite-lto目录，运行

xattr -dr com.apple.quarantine lib/libffmpeg*.dylib
./dylib2framework.sh lib/libffmpeg.dylib

命令，lib目录会生成FFmpeg.framework，把这个framework拷贝到你的项目里，用xcode打开工程，把FFmpeg.framework添加到依赖里，然后编译生成的程序就会链接并打包这个framework，fvp会自动调用它。模拟器版本类似，要同时支持设备和模拟器的话先分别生成framework，再用命令行生成FFmpeg.xcframework，添加到xcode工程依赖里。如果是macos运行好xattr -dr com.apple.quarantine lib/libffmpeg*.dylib后直接把mdk.framework/Versions/A/libffmpeg.7.dylib替换了就行。

[wang-bin]

我给ffmpeg的hls打了补丁，已经可以支持png和gif切片了 https://github.com/wang-bin/avbuild/actions/runs/11091150175

fvp下个版本会集成

另外，iOS的FFmpeg.xcframework也由ci生成了，可以从这下载 https://sourceforge.net/projects/avbuild/files/xcframework/
