Cloudflare Stream + Backblaze 与 GCP 在短视频方面的比较？
嗨，HN，我正在开发一个短视频应用（平均视频时长40秒，预计每天播放量在10,000到50,000之间，且在增长，其中20%的流量来自美国以外，80%来自美国，主要是移动端）。我正在考虑以下两个选项：
1. **Cloudflare Stream + Backblaze (B2)**：
优点：产品简单，按观看分钟数计费（可能比GCP在视频流媒体方面更便宜），内置转码功能。
担忧：不确定他们的自适应比特率（ABR）质量是否能与GCP的质量相匹配，后者在之前的使用中表现非常好。
2. **GCP (GCS + Transcoder API + Media CDN)**：
优点：我之前使用过这个配置，稳定性很好，存储成本低，网络费用也低，流媒体质量出色。而且控制台相对容易操作（尤其是与AWS相比）。我离开GCP是因为与视频流媒体无关的问题（视频智能API的费用异常高），但考虑仅为视频存储和流媒体回归GCP。
缺点：配置转码API时遇到了一些问题，并且担心随着用户增加可能会有隐藏的费用。
如果你使用过Cloudflare Stream或GCP的视频流媒体服务，我很想听听你的看法：
- 短视频的实际播放质量，尤其是1080p/720p的表现和比特率变化。
- 在Cloudflare Stream或GCP视频流媒体服务中，是否存在价格上的陷阱。
- 你遇到的可靠性/操作问题。
我目前倾向于选择Cloudflare Streaming，因为看起来更便宜/更划算，但对视频流的可靠性和质量有所担忧。因此，回归GCP进行视频流媒体服务也许并不是个坏选择。
期待你的想法，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
