Forwarding for compn: """ Re: Paul's question, I don't know exactly what filters were requested. I'll ask on vdd mailing list for answers. The requested filters were broadcast stuff.

The real world metric filters refers to a hypothetical, yet-to-be-written libavfilter wrapper for Netflix' VMAF perceptual metric [1]. It would work like vf_ssim or vf_psnr, but use VMAF. Output of individual metrics that (in aggregate) make up VMAF would be interesting also.

I'm in the CELLAR working group (working on Matorka, FFV1, FLAC) and am also an archivist and can speak to this. The MediaConch project via PREFORMA has some funds to sponsor FFV1 and Matroska development during this year. - Option to add CRCs to Top Level Elements in Matroska when muxing. http://trac.ffmpeg.org/ticket/4347 - Support for selecting an Ordered Edition in mkv: http://trac.ffmpeg.org/ticket/5698 - Bayer pixel format support in FFV1 - Support for additional color information in FFV1 to better handle lossless DPX->FFV1->DPX transfer while preserving characteristics such as if the sampling is logarithmic or linear. Probably others. Feel welcome to suggest a bounty or send questions to myself or Jerome Martinez .

I think these metrices refer to SSIM, VMAF etc... however I think we already have some of these. Not sure about the others, maybe compn can comment. -Thilo ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
