Fix : AsyncImage cannot decode video thumbnail from URI

[jbsession]

Our URI does not have a file extension so we need to check for the MIME type then explicitly set the decoder for the request.

Also fixed play button image.

This will re-execute on every re-composition.
You should probably optimise with something like:

val videoDecoderFactory = remember { VideoFrameDecoder.Factory() }

    val folderThumbnailRequest = remember(context, thumbnailUri) {
        val mimeType = thumbnailUri?.let { MediaUtil.getMimeType(context, it) }

        ImageRequest.Builder(context)
            .data(thumbnailUri)
            .apply {
                if (MediaUtil.isVideoType(mimeType)) {
                    decoderFactory(videoDecoderFactory)
                }
            }
            .build()
    }

You probably want to optimise here as well:

val videoDecoderFactory = remember { VideoFrameDecoder.Factory() }

val mediaRequest = remember(context, media.uri, media.mimeType) {
    ImageRequest.Builder(context)
        .data(media.uri)
        .apply {
            if (MediaUtil.isVideoType(media.mimeType)) {
                decoderFactory(videoDecoderFactory)
            }
        }
        .build()
}
