Unsupported media type

Error message

Unsupported media type

What it means

In `native_get_media_info` (src-tauri/src/platforms/bluesky/mod.rs:41), the post had an embed but `extract_media(embed)` returned None because the embed type is one the downloader does not handle (e.g. `record` quote embeds, `external` link cards, or multi-view embeds without a direct media variant). Only image and video embeds are recognized.

Solutions

1. Only use this downloader on posts with native images or video attached.
2. Extend `extract_media` to unwrap `app.bsky.embed.recordWithMedia` and recurse into quoted records.
3. Log `embed.$type` in the error message to make unsupported types diagnosable.
4. Fall back to the ytdlp generic path which may support the embed type.

Example fix

// before
let media = extract_media(embed).ok_or_else(|| anyhow!("Unsupported media type"))?;
// after
let media = extract_media(embed).ok_or_else(|| anyhow!(
    "Unsupported media type: {}",
    embed.get("$type").and_then(|t| t.as_str()).unwrap_or("unknown")
))?;

const SUPPORTED: [&str; 2] = ["app.bsky.embed.images", "app.bsky.embed.video"];
fn embed_supported(embed: &serde_json::Value) -> bool {
    embed.get("$type").and_then(|t| t.as_str())
        .map(|t| SUPPORTED.contains(&t))
        .unwrap_or(false)
}

When it happens

Trigger: The post's `embed.$type` is not `app.bsky.embed.images` or `app.bsky.embed.video` — for instance a quoted-post embed, an external website card, or `recordWithMedia` whose inner structure extract_media doesn't unwrap.

Common situations: Trying to download a quote post where the media belongs to the quoted record; posts linking to an external video host; new Bluesky embed types introduced after this code was written.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
