这个是streamlink的自动去除广告的内容，因为不录广告，twitch就会一直重复给，导致你少拿了后面十多秒的内容，我开了会员，用会员cookie就没这个问题了，当然可以在下载器里边把去广告功能关了就行了，我这两天看看给这个功能加个开关= =

最新的KNaiFen分支的源码里解决了，增加了去广告的开关，你可以选择不分段但是录进去广告，配置文件里默认开启
PIP的安装版本，要等到发下个版本的时候才会加进去

这种四五个很短的7M左右的，里边确定不是广告吗？你点开来看应该是twitch的紫色标志啥的吧

刚才看了并不是，是主播的视频，被裁剪成几秒钟的片段了。过滤之后，大文件之间不连续，有遗漏

刚才这些上传时被过滤清除掉了，下次我保留一下，看看视频参数是不是不一样

看了下容器的完整日志，看到 skip ad segments 的输出了，里面也有 Connection timed out 和 Interrupted! Exiting 的错误，不知道有没有影响。其他几个小片段也是一样重复的内容。

刚才又录了一段，对比了一下大片段和小片段，发现大片段最后的时间轴与下一个小片段之间丢了22秒左右，每个小片段持续时长正好都是10秒，每个小片段之间也是不连续的，也有丢失（可通过文件名时间+10s和下一段文件名比较）

以下4个视频是连续的4个小片段：

也许与该问题有相似之处。试试自己写参数，用你定义的下载器去下载试试呢？

我之前 downloader 用的 ffmpeg 有这个问题，我昨晚换成 streamlink 好像没发现这个分段问题。

我看了下代码，这个地方的判断是 downloader == 'ffmpeg'，是不是这里应该是 streamlink

biliup/biliup/plugins/twitch.py

Lines 100 to 125 in 6ffe9e1

if self.downloader == 'ffmpeg':
port = random.randint(1025, 65535)
stream_shell = [
"streamlink",
"--player-external-http", # 为外部程序提供流媒体数据
# "--twitch-disable-ads", # 去广告，去掉、跳过嵌入的广告流
# "--twitch-disable-hosting", # 该参数从5.0起已被禁用
"--twitch-disable-reruns", # 如果该频道正在重放回放，不打开流
"--player-external-http-port", str(port), # 对外部输出流的端口
self.url, "best" # 流链接
]
if self.twitch_disable_ads: # 去广告，去掉、跳过嵌入的广告流
stream_shell.insert(1, "--twitch-disable-ads")
twitch_cookie = config.get('user', {}).get('twitch_cookie')
if twitch_cookie:
twitch_cookie = "--twitch-api-header=Authorization=OAuth " + twitch_cookie
stream_shell.insert(1, twitch_cookie)
self.proc = subprocess.Popen(stream_shell)
self.raw_stream_url = f"http://localhost:{port}"
i = 0
while i < 5:
if not (self.proc.poll() is None):
return
time.sleep(1)
i += 1
return True
