Can somebody point me to a sample containing:
MaxCLL - Maximum Content Light Level MaxFALL - Maximum Frame-Average Light Level

It looks like that method of numbering versions has been changed to YEAR.MONTH

Hi Zenitram !
Many thanks for your continued work ! While going through my testfiles I found mediainfo recognising multichannel MPEG Audio Layer 2 streams (I got 4-CH, 5-CH, 6-CH as 5.1, up to 8 shall be possible) as 2 channel streams. I can supply some testfiles, if needed.

https://web.archive.org/web/20150208...at/mpeghdr.htm The so-called "MPEG Multichannel" extension uses a “channel matrixing scheme, where the additional channels are mixed into the two backwards compatible channels”, similar (but apparently not compatible to) Dolby Pro Logic. So, technically, this would still be a Stereo file, just with the signals for the additional "sourround" channels mixed into the actual two (Stereo) channels...

Ah, thank you, that clears it up and at the same time explains why these multichannel files can be decoded with a stereo decoder.
I found Center mixed 50/50 into L/R, SL into L, SR into R.

What are string codes for these items?
Code:
Mastering display color primaries : R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000 Mastering display luminance : min: 0.0050 cd/m2, max: 4000.0000 cd/m2 Maximum Content Light Level : 1529 cd/m2 Maximum Frame-Average Light Level : 380 cd/m2

What is equivalent of
Code:
Transfer characteristics : PQ Code:
--transfer <string> Specify transfer characteristics from bt709, unknown, reserved, bt470m, bt470bg, smpte170m, smpte240m, linear, log100, log316, iec61966-2-4, bt1361e, iec61966-2-1, bt2020-10, bt2020-12, smpte2084, smpte428, arib-std-b67. Default undef

It would be much easier for user if you used well known values like in x264/x265 documentation. In this case smpte2084 instead of PQ,
bt2020nc, bt2020c instead of BT.2020 non-constant/constant. Code:
--colorprim <string> Specify color primaries from bt709, unknown, reserved, bt470m, bt470bg, smpte170m, smpte240m, film, bt2020, smpte428, smpte431, smpte432. Default undef --transfer <string> Specify transfer characteristics from bt709, unknown, reserved, bt470m, bt470bg, smpte170m, smpte240m, linear, log100, log316, iec61966-2-4, bt1361e, iec61966-2-1, bt2020-10, bt2020-12, smpte2084, smpte428, arib-std-b67. Default undef --colormatrix <string> Specify color matrix setting from undef, bt709, fcc, bt470bg, smpte170m, smpte240m, GBR, YCgCo, bt2020nc, bt2020c, smpte2085, chroma-derived-nc, chroma-derived-c, ictcp. Default undef

Sure, as soon as you can prove that what x264/x265 do is "well known" for all people involved with colors. Spoiler: you won't be able to prove that, as I already had the opposite complain ("please use PQ wording, please use well know values, instead of this crazy SMPTE number") during some beta version. Ho, BTW, please hint x265 people to change their name, because they do HEVC, look at the URL here https://en.wikipedia.org/wiki/High_E...y_Video_Coding , "265" is not known by everyone, look it is not in the URL of Wikipedia English (but it is in the French version, funny isn't it?), why do they mislead people with "265" thing? (I use "HEVC" word, sorry "H.265" people) (A bit) more seriously, please don't do assumption that x265 people have the "real truth", they are not the center of the universe and they don't represent the industry as a whole (because the industry is not a whole), and in the case of "PQ" it is the "well known value" used by one of my sponsor, a lot known in this industry, and actually my policy is to try to avoid SMPTE number (side note: this is "SMPTE ST 2084", not "SMPTE 2084") when I can because they are difficult to memorize (and are less known than the BT ones), beside prioritizing American names (MPEG ones: AVC, HEVC...) other ITU names (H.264, H.265) when it is a joint venture with only different names in their respective standard bodies. Warning, in the next release there is a change in order to meet this policy, as I was not aware of "well known names" (remark: someone complained about the exact opposite of your remark when he indicated new names, because I was using SMPTE numbers, the ones used by x265, and not "well known names" from his point of view, he wanted me to replace by his "well known values"), I used SMPTE numbers 431-2 and 432-1 (funny isn't it that such numbers are difficult to differentiate? Worse, one is "RP" and the other is "EG" and 431 alone does not exist, it is 431-2) only because I was not aware of "well known names" and I'll replace them by "DCI P3" and "Display P3" (commit). summary: your "well known values" are not the "well known values" of some other people, and whatever I choose, someone will complain, this is not the first time and it will not be the last time, as MediaInfo is used by a lot of very different people in this industry, each "community" having different "well known value", when I choose a name I am sure another "community" will complain. I may add option "choose your community" in the future if people are crazy enough for paying for seeing their "well known values" instead of the ones I chose. PS: bt2020nc means exactly "BT.2020 non-constant", I just show something more "readable", why should I limit the display to a limitation of the command line? I may use "codes" (short names without spaces) internally in the future, but nothing says that I would use x264/x265 choices vs other tools choices. PPS: in an ideal world, everyone would speak the same language and everyone would use the same "well known values", unfortunately we are not in this ideal world so if you don't do any "translation", someone else will do the same remark about his need to have a translation between your values and his values.

Do you have a full list of "your well known codes" so I could translate them to "my well known codes" for x264/x265 use?
I just need to know that I pass correct codes to encoder. That's all.

I tested a few more files just to see if I could find more differences, only found two:
I got an old folder with 8 calibration mp4s. Online doesn't show x264 settings and nominal bitrate on 7 of them https://www.diffchecker.com/oUUJHGmc the 8th does correctly show x264 settings and nominal bitrate, it's the only one of them that is larger than 1MB, the rest are smaller than 1MB. This one doesn't show source duration and Source stream size online https://www.diffchecker.com/cgPO4RsV though in this case source duration and duration are the same so it doesn't matter much, though it would be nice to have the exact same output online if possible. I tested old youtube downloads, some old xvids, vobs from DVDs, some more recent x264 mkvs, hevc hdr video, TV recordings, and some more unusual video like vfr cellphone video, unusual framerates, various containers (mp4, mkv, ts, flv, m2ts), also besides video, some flac, mp3, png, gif and some other files, all had the same output as 17.12. btw I'm using Win 10 + chrome x64 |
