Cloudflare Stream + Backblaze vs. 谷歌云平台（GCP） 短视频解决方案对比？
1 分•作者: slroger•6 个月前
大家好，我正在开发一款短视频应用（平均视频长度40秒，预计每天播放量1万到5万次，并且还在增长，其中20%的流量来自美国以外地区，80%来自美国，主要在移动端）。我正在考虑以下两种方案：
1. Cloudflare Stream + Backblaze (B2):
优点：产品简单，按观看分钟数计费（可能比GCP的视频流服务便宜），内置转码功能。
担忧：不确定它们的自适应比特率（ABR）质量是否能达到GCP的水平，我之前使用GCP时效果非常好。
2. GCP (GCS + Transcoder API + MediaCDN):
优点：我之前用过这套方案，非常稳定，存储成本低，网络费用也低，而且流媒体质量极佳。控制台也相当容易操作（尤其是与AWS相比）。我离开GCP是因为与视频流无关的问题（Video Intelligence API非常昂贵），但现在正在考虑为了视频存储和流媒体服务而重新使用它。
缺点：配置转码API时遇到过一些问题，并且担心随着用户增加，可能会出现一些隐藏的费用。
所以，如果你使用过Cloudflare Stream或GCP的视频流服务，我很想听听你的看法：
* 短视频的实际播放质量，特别是1080p/720p的播放效果，以及CloudStream的比特率阶梯。
* CloudStream或GCP视频流服务的定价方面是否存在任何隐藏费用。
* 你遇到过的可靠性/运营问题。
我目前倾向于Cloudflare Stream，因为它看起来更便宜/更划算，但我担心视频流的可靠性和质量。所以，也许重新使用GCP进行视频流服务也不是一件坏事。
期待您的想法，谢谢。

Hi HN, I'm building a short form video app(avg clip length 40 seconds, expecting 10-50,000 plays per day, growing, with 20% of traffic outside the US,80% in the US, mostly mobile). I'm deciding between:<p>1.) CloudflareStream + Backblaze(B2):
Pros: Simple product, minutes viewed pricing(possibly cheaper than GCP for video streaming), built in transcoding.
Concern: not sure if their ABR quality will match the quality of say GCP's which was really good in prior use.<p>2. GCP(GCS+TranscoderAPI+MediaCDN)
Pros: I used this set up previously and it was robust, storage was cheap, network costs were low and the streaming quality was excellent. And the console was fairly easy to navigate(especially compared to AWS) I left GCP because of non Video Streaming related issues(Video Intelligence API was exceptionally expensive) but considering going back just for Video storage and streaming
Cons: There were some issues configuring the transcoder API and also concerned there may be gotcha prices as I get more users<p>So if you've used Cloudflare Stream or GCP's video streamin services I'd love your take on:
Real world playback quality for short videos especially 1080p/720p behaviour and bitrate ladders on CloudStream.<p>Any gotchas in pricing when it comes to either CloudStream or GCP Video Streaming services<p>Reliability/Operational issues you've run into.<p>I'm currently leaning on Cloudflare Streaming as it seems cheaper/better deal but concerned about reliability and quality of video streams. So maybe going back to GCP for video streaming wouldnt be so bad.<p>So looking forward to your thoughts, thank you
