inject these in your constructor:
\Magento\Catalog\Api\Data\ProductAttributeMediaGalleryEntryInterface $MediaGalleryEntry,
\Magento\Framework\Api\Data\ImageContentInterface $imageContentInterface,
During product creation I do something like this:
$mediaGalleryEntry = $this->_mediaGalleryEntry;
$mediaGalleryEntry->setLabel($name);
$mediaGalleryEntry->setTypes(array("image","small_image","thumbnail"));
$mediaGalleryEntry->setStoreIds($storeIds);
$mediaGalleryEntry->setMediaType('image');
$mediaGalleryEntry->setPosition(0);
$imageContent = $this->_imageContentInterface;
$imageContent->setName($name);
$imageContent->setType($imageType);
$imageContent->setBase64EncodedData($imageData);
$mediaGalleryEntry->SetContent($imageContent);
$product->setMediaGalleryEntries(array($mediaGalleryEntry));
