[FFmpeg-devel] VP6 Encoder Proposal- Seeking Feedback and Suggestions

[FFmpeg-devel] VP6 Encoder Proposal- Seeking Feedback and Suggestions

[SUBHANGANI JHA]

Hello FFmpeg developers,

I'm a 2025 Gsoc applicant and have submitted a proposal for implementing a
basic VP6 Encoder in FFmpeg. I understand the importance of community
engagement and am reaching out to introduce myself and seek any guidance,
feedback,or suggestions you might have on the idea or the approach .
While the proposal is already submitted, I'm highly interested in
contributing regardless of the outcome and would love to get more involved
with the FFmpeg development process .
If there are small tasks or bugs I could help with, or if there is any
documentation or suggestions for working with encoding pipeline in FFmpeg,
I would really appreciate being pointed in the right direction.


Looking forward to hearing from you and contributing.


Best regards,
Subhangani Jha

Iam not sure someone else has already replied
but if you (or someone else) is looking for suggestions there are many

some ideas that come to my mind
as you mention encoder.
a current example would be the FFv1 encoder
there are for example 3 different ways to code LSBs. These are in
3 patches on this mailing list. These could be compared in terms of
speed and compression. Though likely each patch would only apply
cleanly to a git checkout from around that time.

If you are interrested in this, i can look at and provide exact
links to the patches

thx
