youtube-audio/video uploader

hello i require two tasks in this project , both of them are very similar. i have created software on my site where i allow users to record video and audio through my website and then upload it to youtube then it shares/embed the link on the post ( which is good so far ) except that it share the video with ( privacy set to Public "because that is the default settings on youtube for new uploaded videos") ------------------------ *) i want to add a line or two lines of code where i can change this into "unlisted" , so it can only be embedded or watched through my website only. ---------- --- Secondly :- --------------------------- **i am not sure if it's possible or not** i know youtube doesn't allow users to upload audio files , but i kind need to Record audio only and share it on youtube just like the video recorder above so for that i was thinking , maybe record the video and attach an "image/gif/small animation" on a certain directory on my site ( example public_html/video ) and that image be on the whole video along with the audio file . ofcorse set the video to be Unlisted privacy too just like the video above. ------------------------- i know youtube have a lot of templates , codes and api to help you finishing the project for example ([login to view URL]) so let me know if you are interested and whither you can get the job done or not also if Second part is possible ? and i will share my code with you so we can start working.
