[FFmpeg-devel] Re: [PATCH 0/3] tests: improve FATE coverage for film_grain_params, CNG, aderivative/aintegral

[Marcos Ashton via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

Hi Hassan,

Thanks for the suggestion! I submitted via the mailing list as that's what
the developer docs and the GSoC project page pointed me to is
code.ffmpeg.org now the preferred place for new patches? Happy to mirror
there too if it helps with review.

Marcos
