私のプロジェクトでは、Symfony2.3 で Sonata Media Bundle を使用しています。YouTube プロバイダーsonata.media.provider.youtubeをオーバーライドすると。すべて正常に動作しています。エラーも何もありません
/Web/uploads/media
サムネイルは生成されませんが、管理ダッシュボードに表示されます:
/uploads/media/default/0001/01/thumb_9_default_small.jpg.
方法はわかりませんが、sonata.media.provider.youtubeをオーバーライドしないと、サムネイルが生成されます
/web/uploads/media/
お気に入り ：
/web/uploads/media/default/0001/01/thumb_9_default_small.jpg.
どうしてか分かりません ？

'rel' => 0,
// Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay
// when the player loads.
'autoplay' => 0,
// Values: 0 or 1. Default is 0. In the case of a single video player, a setting of 1
// will cause the player to play the initial video again and again. In the case of a
// playlist player (or custom player), the player will play the entire playlist and
// then start again at the first video.
'loop' => 0,
// Values: 0 or 1. Default is 0. Setting this to 1 will enable the Javascript API.
// For more information on the Javascript API and how to use it, see the JavaScript
// API documentation.

// JavaScript API. See the JavaScript API documentation for details.
'playerapiid' => null,

// Keyboard controls are as follows:
// Spacebar: Play / Pause
// Arrow Left: Jump back 10% in the current video
// Arrow Right: Jump ahead 10% in the current video
// Arrow Up: Volume up
// Arrow Down: Volume Down
'disablekb' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables the "Enhanced Genie Menu". This
// behavior causes the genie menu (if present) to appear when the user's mouse enters
// the video display area, as opposed to only appearing when the menu button is pressed.
'egm' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables a border around the entire video
// player. The border's primary color can be set via the color1 parameter, and a
// secondary color can be set by the color2 parameter.
'border' => 0,
// Values: Any RGB value in hexadecimal format. color1 is the primary border color, and
// color2 is the video control bar background color and secondary border color.

'color2' => null,

// effect on the Chromeless Player. Note that you must include some extra arguments to
// your embed code for this to work.
'fs' => 1,
// Values: A positive integer. This parameter causes the player to begin playing the video
// at the given number of seconds from the start of the video. Note that similar to the
// seekTo function, the player will look for the closest keyframe to the time you specify.
// This means sometimes the play head may seek to just before the requested time, usually
// no more than ~2 seconds
'start' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables HD playback by default. This has no
// effect on the Chromeless Player. This also has no effect if an HD version of the video
// is not available. If you enable this option, keep in mind that users with a slower
// connection may have an sub-optimal experience unless they turn off HD. You should ensure
// your player is large enough to display the video in its native resolution.
'hd' => 1,
// Values: 0 or 1. Default is 1. Setting to 0 disables the search box from displaying when
// the video is minimized. Note that if the rel parameter is set to 0 then the search box
// will also be disabled, regardless of the value of showsearch.
'showsearch' => 0,
// Values: 0 or 1. Default is 1. Setting to 0 causes the player to not display information
// like the video title and rating before the video starts playing.
'showinfo' => 0,
// Values: 1 or 3. Default is 1. Setting to 1 will cause video annotations to be shown by
// default, whereas setting to 3 will cause video annotation to not be shown by default.

// Values: 1. Default is based on user preference. Setting to 1 will cause closed captions
// to be shown by default, even if the user has turned captions off.

// Values: 'window' or 'opaque' or 'transparent'.
