Idea: convert our episode audio files into mp4, then upload to YouTube automatically

[LinuxSuRen]

YouTube already have the Postcast support. It would be great to convert our episode audio files into mp4, then upload to YouTube automatically. For example, we could find or create a CLI to do it. Then create a GitHub workflow to trigger it.

I found some potential tools could help us:

• https://github.com/tokland/youtube-upload
• https://github.com/porjo/youtubeuploader

The steps might be:

• Check if the episode exist in YouTube
• Convert the mp3 to mp4 with a picture
• Upload the mp4 file

See also the following example command:

ffmpeg -loop 1 -i logo.png -i osf2f-s01e21-richard.mp3 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black,setsar=1,format=yuv420p" -shortest -fflags +shortest osf2f-s01e21-richard.mp4

Although Google Podcasts has been merged into Youtube Music, Youtube is still a very important channel. And we look forward to someone someone with experience in service development to implement this feature.

What is the workflow? Where can I get the mp3 files and YouTube video title information? It seems that I only need to write some short scripts to achieve it.

I guess the workflow is like this. When the RSS is updated, get the mp3 file and transcode it (executed through GitHub action), and then upload the mp4 file through YouTube's API.

The mp3 files can be obtained from our RSS, and the video information is in shownotes.

Will there be such a risk?

[wey-gu]

Maybe the concern comes from running CPU-intensive tasks (i.e. FFmpeg converting job) with GH Action?

@yihong0618 had a lot of hacking GH action experiences to alert such concern, maybe please you could share more context?

[yihong0618]

@LinuxSuRen @wey-gu do some search, for this job I think its OK.
but what I am concern is that for a official account it still be risk, something like https://www.v2ex.com/t/874221

I will try to implement this issue. Here's a question.

The "Check if the episode exists in YouTube" step may cause problems due to anti-crawlers. Can we save a log file locally to record the uploaded videos?

That will do!

Another mitigation to avoid being treated as malicious probe would be checking via rss interface/ proxied rss:

https://www.youtube.com/feeds/videos.xml?channel_id=THE_CHANNEL_ID_HERE

While, I agree with you that in current slo, maintain local state may be much better in many perspectives.

aha, what is the channel ID of osf2f? It seems that only the author can see this ID himself.

Here is the channel. https://www.youtube.com/channel/UCV7Ibg1k_aMSEcDFgJvuvdg

But please make sure that everything is ok before using it. And thanks for your effort.

我尝试去解决这个问题，但是遇到了2个问题 https://github.com/hellojukay/episode/actions

1. 在 github action 里面进行 mp3 转 mp4 速度非常慢，一个视频大概需要 40 多分钟
2. 上传 mp4 到 youtube 认证需要浏览器重定向点击认证，也可以使用 token , 但是 token 七天会过期
3. 判断 mp4 在 youtube 是否已经存在，可能比较麻烦，需要调用 api 之类的，也存在应用认证的问题。

2. 上传 mp4 到 youtube 认证需要浏览器重定向点击认证，也可以使用 token , 但是 token 七天会过期

It seems it was in status "Testing" causing the refresh token expiring in 7 days, for production refresh token, it's longer, someone said it's like 1 year?

3. 判断 mp4 在 youtube 是否已经存在，可能比较麻烦，需要调用 api 之类的，也存在应用认证的问题。

As I mentioned above, we may leverage the RSS of the channel to probe content without auth?

This is not a big problem. We can wait.

Acrrroding to @wey-gu comment, one year's token seem be acceptable.

By the way, the RSS address of YouTube seems not available. See also https://www.youtube.com/feeds/videos.xml?channel_id=UCV7Ibg1k_aMSEcDFgJvuvdg

“https://www.youtube.com/feeds/videos.xml?channel_id=UCV7Ibg1k_aMSEcDFgJvuvdg” should be the one, maybe just accessing via browser is not allowed, I checked via feedly it's fine.

<link rel="alternate" type="application/rss+xml" title="RSS" href="https://www.youtube.com/feeds/videos.xml?channel_id=UCV7Ibg1k_aMSEcDFgJvuvdg">

[wey-gu]

update: it seems rss for youtube is full of problems, we could think of it doesnt support rss at all :(

[LinuxSuRen]

I cannot get the correct RSS content even via the following command:

curl https://www.youtube.com/feeds/videos.xml?channel_id=UCV7Ibg1k_aMSEcDFgJvuvdg \
  -H "Content-Type: application/rss+xml" -H 'Accept: application/rss+xml'

Yeah, i have done the equivalent via python and encountered 404, too.
