WordPress, TV Series, music, kids, and board games. I think that’s probably the best way to define me in a few words. 🙂

I work at Automattic where I lead a team building tools for bloggers and creators. I talk a lot about WordPress things, but also about all things open source in general.

I post in English and in French.

I live in Brittany, France, so you’ll also find me sharing pictures from our beautiful region from time to time.

I keep bumping into an annoying Mastodon bug. ActivityPub and the Mastodon API can serve posts with multiple attachments of different types (e.g. images and audio files), but the Mastodon web UI does not know how to display such posts. I must remember not to publish posts that have both an audio file and an image, or the audio file only appears as a blank image on Mastodon.

Screenshot of the Mastodon web UI. It shows a gallery of 2 images. The second image is all black. It is in fact an audio file that Mastodon doesn't know how to display.

The good news is, most other Fediverse apps and clients seem to know how to handle such posts. Here is the same post in Semaphore and Tusky for example. Tusky does not display any preview at all, which isn’t great, but you can still play the audio file by clicking on the file name.

Screenshot of a post in the Semaphore Fediverse client. A Play button appears above the audio file.
A screenshot of the same post in the Tusky app. No media preview appears, but you can view the image and listen to the audio file by tapping on the media name.

So PSA: if you publish videos or audio files on the Fediverse, remember to post them on their own with no other attachment if you want them to be displayed properly on Mastodon!

This is tracked in this GitHub issue: Allow posts to have mixed media attachments (images AND video/audio)
