for past couple weeks co workers , me have been working on trying captions on our clients youtube video's through v3 api. after week able captions upload fine but, youtube give message in ui "track content not processed" , doesn't display caption's upload. however, can download original format upload; know file uploaded successfully.

we able sync flag work tells youtube run through transcript , set timings video but, doesn't work. returns telling syncing when go ui video shows caption track name , give's message "track content not processed.". we've used hours had , we're working on our own time solve problem still no luck.

has ran problem before? if so, able work?

i post snippet of code below shows upload portion of our script.

# insert video caption. # create caption snippet video id, language, name , draft status. $captionsnippet = new google_service_youtube_captionsnippet(); $captionsnippet->setvideoid($videoid); $captionsnippet->setlanguage($captionlanguage); $captionsnippet->setname($captionname); $captionsnippet->setisdraft( true );  # create caption snippet. $caption = new google_service_youtube_caption(); $caption->setsnippet($captionsnippet);  // setting defer flag true tells client return request can called $client->setdefer(false);  // file content's of uploaded file $file = file_get_contents( $captionfile['tmp_name'] );  // create request api's captions.insert method create , upload caption. $insertrequest = $youtube->captions->insert("snippet", $caption, array(    'sync' => true,    'data' => $file,    'mimetype' => 'application/octet-stream',    'uploadtype' => 'multipart' )   );   echo '<pre>'; print_r( $insertrequest ); echo '</pre>';  // // read caption file , upload chunk chunk. $status = $insertrequest; fclose($handle);  // if want make other calls after file upload, set setdefer false $client->setdefer(false);
