searched issues

I didn't find any issues for MOV. I found a mention of video-support in #2217:

We currently treat unrecognized video formats such as WMV as video attachments even though they can’t be played in Chromium.

But MOV files do play in Chromium

Feature Request Description

Play MOV video files in the Signal Desktop app.

Steps to Reproduce

1. send a MOV file to anyone, (e.g. to Note to Self)
2. open the chat on a Signal Desktop app (e.g. on Mac)

Actual Result:

There is no preview or play option in the app. The attachment can only be downloaded.

Expected Result:

There should be a video preview. And a play button to play it without leaving the app.
Here's how it looks like in the Android app:

Platform Info

Signal Version: v1.34.4

Operating System: macOS Catalina 10.15.6

Linked Device Version: Android 4.67.3

I came here while searching for a list of which video formats are presently supported by Signal-Desktop. I had the same result as above using an MKV file (video format h264) and I would like to know how to format videos to play in both Desktop and the App
mkvfile.zip

I would like to know the same. I attached an .avi file via the Signal Desktop, but it cannot play there and on iOS. It would be great to know the supported file types.

I was also curious; per the source code

const SUPPORTED_VIDEO_MIME_TYPES: MIMETypeSupportMap = { 'video/mp4': true, 'video/ogg': true, 'video/webm': true, };

should inline.
