In YouTube, there are many videos of tamil public talks available. They are on literature, history, politics and more.

Though the uploaded did not choose the license, who owns the copyright?

The speaker

The Video recorder

The event organizer

The venue owner

The public

I want to make podcasts using those talks. I attend few events and record the same talk myself as audio.

Now there is no difference between my recording and the one on YouTube.

Now is it OK to upload my audio files to archive.org in a CC license?

If the license of a public event is any one of public license, shall I rip the audio from YouTube talks of public events, and release in a CC license?

Share your thoughts.

Thanks.
