Audio support #44

Open snowway opened 1 month ago

snowway commented 1 month ago

This project is great and the API is very user friendly, but when I converted the original video, I found that the audio information was lost. can anyone help me?

hi, luckily i am having a similar use case. you have to use ffmpeg4-sys to decode the audio separately. in the midterm, it would be wise to contribute to video-rs to have this functionality. check this blog post: https://subvisual.com/blog/posts/real-time-video-processing-with-rust-ffmpeg-opencv/

unrelated but do you have an idea on how to cut video using this library? would it be possible to preview video in real time? there lacks examples or i lack knowledge.

Hi @snowway would you like to collaborate on an audio encoder? I have an 8 day deadline.

Unfortunately, audio is not supported right now. Any contributions would be greatly appreciated though.

kaixoo commented 1 month ago

Could easily contribute if I get indication on where the change should be made, etc. at least for basic formats like mp3. Do you have Discord or matrix?

Probably the easiest way would be to add an AudioDecoder interface next to the existing decoder.
