Missing preview image in macOS WhatsApp client

[ianrobertlambert]

Issue Description:

When I attempt to share an MP4 downloaded using Cobalt on WhatsApp, I notice that it lacks a video preview. I have tried downloading videos with different codecs, but the issue persists. Interestingly, when I use other download tools, the WhatsApp video preview is present. I prefer using Cobalt for my downloads, and I'm wondering if there's any way to fix this issue?

Steps to Reproduce:

1. Download an MP4 video using Cobalt.
2. Share the downloaded MP4 video on WhatsApp.
3. Observe that the video preview is missing.

Expected Behavior: I expect the MP4 videos downloaded with Cobalt to include a video preview when shared on WhatsApp, similar to other download tools.

could you give me a sample link and tell me what platform this issue is present on (android/ios/web/etc)?

[ianrobertlambert]

• Any video I attempt to download from Reddit (example hosted on Reddit).
• Cobalt for Raycast (macOS).

i suppose the whatsapp client is on macos, right?

i didn't make the raycast extension and can't try it out (i don't have a mac), so you gotta help me pinpoint the issue yourself:

1. download something else (such as a youtube video) with raycast extension and lmk if preview issue is still present.
2. download the video from https://cobalt.tools and lmk if preview issue is still present.

please report back to me if anything changes or goes wrong!

Thanks for taking a look at this. 🙏

1. Downloaded a YouTube video using the Cobalt for Raycast extension and the issue still persists.
2. Downloaded a YouTube video using https://cobalt.tools/ and the issue still persists.

Notes:

• The WhatsApp client is on macOS.
• I downloaded the same video using another tool and there is no issue. The WhatsApp video preview works.
