You're right. I didn't mention it because I thought it wasn't related to this seeking "issue". I thought that seeking the audio stream wouldn't seek the video stream too.
Here the audio is MP3. And I don't know how audio and video were muxed together, this is a testing video file I took from my hard disk. But this is not important, because I want my library to be able to read a wide variety of formats, thus the muxing of this specific video file shouldn't be a criteria.

Yes, that's it. Thank you very much!
