ProRes / DNxHR conformed outputs are unplayable in the browser
(HTML5 video: MEDIA_ERR_SRC_NOT_SUPPORTED). The library was
referencing the ProRes original as the only source.
After the asset row is inserted, queue an H.264 proxy build the same
way services/mam-api/src/routes/assets.js does on ingest:
proxyQueue.add('generate', {
assetId,
inputKey: outputKey, // the conformed mov / mp4
outputKey: `proxies/${id}.mp4`,
});
The proxy worker writes the H.264 mp4, updates assets.proxy_s3_key,
and from then on /assets/:id/stream prefers the proxy over the
original. The library player can decode it natively.
Failure to enqueue is logged but doesn't fail the conform job — the
asset still exists and can have a proxy re-queued later.
