StreamLive ProPost videos and text to Mastodon
Post to Mastodon from StreamLive Pro: connect any Mastodon server, post text, a photo or a video now or on a schedule, and how your server's limits apply.
Mastodon is not one site but many servers, so StreamLive Pro connects to whichever server your account lives on. You type your server's address once, sign in there, and from then on Mastodon is a tick box on Publish everywhere. Each post can carry text plus one photo or one video, within the limits your server sets.
Before you start
- Your server's address. It is the part after the second @ in your Mastodon address. For example, for @[email protected] it is mastodon.social.
- Your server's limits. Text length and file sizes are set by each server. StreamLive Pro reads the limits from your server when it posts, and uses 500 characters when the server does not say.
- A plan with room for one more publishing account. Each plan allows a number of publishing accounts; see /pricing?lang=en.
Steps
- Start the connection. In Connections choose Mastodon.
- Type your server. Enter the server address, for example mastodon.social, and continue. StreamLive Pro registers itself with your server at that moment, so it works with any Mastodon server that answers like one.
- Sign in on your server. Your server's own sign-in page opens. Sign in and approve. The account appears as Mastodon account.
- Write the post. Open Publish everywhere. Write the text in the Text box and, if you like, add one photo or one video on Drop a video or photo here.
- Pick Mastodon. Under Post to click the account so it is selected.
- Check the limits. The Mastodon tab in Adjust per network shows its character limit, and the preview's Where it goes list warns when something does not fit. If your text is long, give Mastodon its own shorter text on that tab.
- Publish, then wait for a video. Under When choose Now or Schedule, and click the button at the bottom. Mastodon processes a video before it can be posted; the post in Activity gets a link when your server is done.
What happens to your post
| Part | What StreamLive Pro does |
|---|---|
| Text | Sent as the post. If it is longer than your server allows, it is shortened to the limit and the result says so |
| Photo or video | Uploaded to your server first. One file per post |
| A file over your server's limit | Not posted. The result names the size your server accepts |
| A video | Waits for your server to finish processing it, up to 10 minutes. If the server takes longer, nothing is posted and you see why |
| Hebrew text | Marked as Hebrew, so Mastodon's language settings treat it correctly |
| Text and file both empty | Refused: a Mastodon post needs text, a photo or a video |
Things to know
- Several accounts. Accounts on different Mastodon servers can each be connected, and each one is its own tick box. One post can go to all of them and to your other networks at the same time, with a separate result for each.
- Deleting. Delete everywhere does not remove Mastodon posts. Delete them on your server.
- Disconnecting. Removing the connection in Connections also asks your server to cancel StreamLive Pro's access.
What can go wrong
| Symptom | Likely cause | Fix |
|---|---|---|
| "Enter your Mastodon server" | The address was empty or not a server name | Type only the server part, for example mastodon.social |
| "We could not reach the Mastodon server" | A typo, or the server is down | Check the spelling; try again later |
| "The file is larger than your Mastodon server accepts" | Your server's file limit | Shorten or compress the video, or post a link instead |
| "Your Mastodon server is limiting posts right now" | Your server's rate limit | Wait and press Retry |
| "Mastodon no longer accepts this connection" | Access was revoked or expired on the server | Reconnect Mastodon in Connections |

Frequently asked questions
Which Mastodon servers does StreamLive Pro work with?
Any server that answers like a Mastodon server. You type its address, and StreamLive Pro registers itself there when you connect.
How long can my Mastodon post be?
As long as your server allows. StreamLive Pro reads the limit from your server and shortens longer text to it, with a note in the result.
Can I post a video to Mastodon?
Yes, one video per post, within your server's file size limit. The post goes out once your server finishes processing the video.
Can I schedule Mastodon posts?
Yes. Choose Schedule on the publish screen. The post goes out at that time even if your computer is off.
Do I need to give StreamLive Pro my Mastodon password?
No. You sign in on your own server's page and approve access there. StreamLive Pro never sees the password.
