Note that most modern browsers limit the maximum number of simultaneous HTTP connections. Thus, if you show a lot of renditions simultaneously (e.g., thumbnails in an asset list), strongly consider using the mode argument to limit the number of simultaneous HTTP connections. Please be careful that you do not cache the fallback image as the requested image.
In rare cases, the generation of a rendition might fail. In the old transcode system, an asset streamer URL would not be returned in this case. In the new transcode system, an asset streamer URL is returned in this case, but the asset streamer request returns an HTTP 502 error. If the mode is set to getFallbackImageIfUnavailable, a fallback image is still returned in this case.
If you are using the SDK, be aware that the default HTTP client used by the SDK has a timeout of 100 seconds. Thus, if you request a rendition that takes more than 100 seconds to become available with the INewAssetStreamerService.GetAssetDownloadStream method, your request will time out before the rendition is returned. To disable this timeout, use the following setup in your application startup logic:
