复现步骤

const res = await Taro.chooseVideo({
            fail: (err) => {
                console.log('fail', err)
            },
            success: function (r) {
                console.log('success', r)
            },
            complete: (r) => {
                console.log('complate', r)
            },
        })

无论是回调的写法，还是 Promise 的写法，都没有回调。

Android 正常

期望结果

实际结果

触发了文件选择，选择之后，既没有触发 success，也没有触发 fail

问题已经找到，因为 safari 下，永远不会触发 oncanplay ，所以不会resolve，也不会 reject。

应该是不支持播放 video/quicktime 视频

已经解决，在 Reader 的 onload 事件 resolve 之后即可

// 对齐旧版本实现 
   reader.onload = (event) => { 
     res.tempFilePath = event.target?.result as string 
+   resolve(res)
   }

另外为了 thumbTempFilePath 然后加载整个视频，并且还有兼容性，觉得不太值当

是的，想不到如今才有人发现这个问题，说明用Taro的人还是很少。

最近写了一个组件库： https://github.com/sutras/sard 。

为了兼容H5，专门针对H5自行实现了chooseVideo接口。

我在使用Taro.chooseMedia也遇到了这个问题。
