Re: [FFmpeg-user] Play video and simultaneously record audio
I've written a summary into my book in chapter 3.16 (but chapter numbering may change in future): http://www.astro-electronic.de/FFmpeg_Book.pdf Book contains obsolete info about v360 filter, please fix it. Done. Many new examples for the v360 filter added to chapters 2.48 to 2.55 http://www.astro-electronic.de/FFmpeg_Book.pdf Michael ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

I'm probably gonna add at some point mask option which will fill unused pixels with max alpha values. To make stitching possible with multiple flat(or any other projection format) inputs, this would also make possible to replace all alpha values with custom picked color by using overlay filter. > > Some suggestions for documentation: > -- "perspective" needs better description what it is.

Re: [FFmpeg-user] V360 filter
Paul, Single-fisheye is done as output only currently, user need to set both h_fov and v_fov. I'm just testing the new single fisheye options and as far as I have tested, everything looks good. Would it be possible to add an option for filling the unused area with a user-defined color, instead of the default black? Some suggestions for documentation: -- "perspective" needs better description what it is. I don't know. -- "ball" is the same as when the whole 360° environment is seen as a reflection in a mirror ball Michael ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Could you please give me a hint where to find the exact equations of transformations made when converting 10bit yuv to 16bit RGB/sRGB in the output PNG file?
