Feat: Intial FFmpeg av1 codec support with dav1d

[anilbeesetti]

Need to look into why ffmpeg libdav1d software decoder can't play av1 videos

[fenjuly]

hi @anilbeesetti,

I greatly appreciate that you have open-sourced this project. I am using your project for software decoding playback. I have found that even after compiling the libdav1d decoder, AV1 format videos still cannot be played correctly. It seems like you have encountered the same issue. Have you managed to resolve it, or do you have any good suggestions?

Looking forward to your reply. Thanks!

Hi @fenjuly, thanks for reaching out. I'm haven't gotten time to look into this one. I'll try to work on this in the upcoming weeks and will also try other AV1 decoders to see if this issue occurs in those decoders too

Hi @anilbeesetti ,
I would like to update you on the progress of my latest investigation: I tried using the libaom library to play AV1 format videos and found that it works properly. If you agree, I can submit a pull request to modify the build script to replace libdav1d with libaom.

Hey @fenjuly, That would be great.
