According to this SO answer, you cannot upload video directly into a playlist. It's normal that when uploading video, it will redirect to your channel. Once it's uploaded in the channel, you can now put it in the playlist.
If the video is already uploaded, you can follow this Adding a video to a playlist documentation. You can add a video to a playlist by using a VideoEntry object.
Here's a sample code retrieves a VideoEntry object with a known entry ID and then adds it to the playlist corresponding to the PlaylistListEntry object. Since the request does not specify a position where the video will appear in the playlist, the new video is added to the end of the playlist.
$postUrl = $playlistToAddTo->getPlaylistVideoFeedUrl();
// video entry to be added
$videoEntryToAdd = $yt->getVideoEntry('4XpnKHJAok8');
// create a new Zend_Gdata_PlaylistListEntry, passing in the underling DOMElement of the VideoEntry
$newPlaylistListEntry = $yt->newPlaylistListEntry($videoEntryToAdd->getDOM());
// post
try {
$yt->insertEntry($newPlaylistListEntry, $postUrl);
} catch (Zend_App_Exception $e) {
echo $e->getMessage();
}
