HEVC(H.265) compliance streams

I've encoded a testsuit for HEVC compliance streams (HEVC test vectors/conformance streams).
Hope it may help SW/ASIC decoder & stream analyzer tools improve decoding capabilities and robustness.

Your valuable suggestions and prompt feedbacks encourage me to make it perfect.

Should you have any questions, plz leave a message. Thank you !

Can you please translate everything on that site to english? Yes, i could use a translator, but for the majority, chinese isn't very helpful on an english forum.

I believe that he has already translated them into English. You can read the English translation below the Chinese part.

No, he clearly has Chinese and English mixed up on his page text, there's no translation at all.

HEVC(H.265)官方给出的compliance test sequence/clip都很有针对性,从这次test sequence(一致性测试码流)的种类和数量看出,ITU在HEVC(H.265)上面吸取了H.264的一些经验教训,鼓励各个组织和公司提交方案和特征流,以此为基础,努力提高官方码流的覆盖度。

本人一直在研究视频编解码,深刻地明白:无论是软件解码还是ASIC,一组好的码流集对于提高语法验证的覆盖度(coverage)的重要意义。 出于兴趣,自己开发了一组HEVC/H.265的一致性测试码流,供大家免费使用,但请注明出处(商业和研究用途尤请注明):

Sorry for the ambiguous description first.

For non-Chinese readers, I believe the English description is enough for understanding what the suit is, so plz don't care about what the Chinese Part says.

But, I will translate the whole text into English soon.

What I expect is your comments on the compliance test suit, not the Language. Thank you ~

We can only comment on something if we fully understand it first. And since I clearly don't understand it, without having to use an external translator, even though I have a good understanding of the technical background, I won't bother, as will probably other people, too. Which is a shame.

Just a friendly advice, it has nothing to do with your work or your contribution at all.

Thank you for your kindly advice. I've translated the whole text into English, hope it can help improve the capabilities of SW/ASIC HEVC decoder.

This suit is very helpful to test HEVC analyzer tools, such as Zond265, Elecard HEVC Analyzer, and CodecVisa.

compliance test sequences and clips offered by ITU official are quite specific, it apparently learned some more from H264, you could tell from the sort and quantity of the compliance test sequences, and ITU encourages organizations and companies to submit schemes and test sequences, and tries to maximize the coverage of the official sequence based on them.
I've been doing the research about video en/decoding, trying to improve the coverage of the syntax elements, I know how much a decent test sequence means to it, software decoding or ASIC, and so I made a compliance test stream for H265 out of curiosity, it's free but leave a note about the source if wanna use it to research or do commercial developments

just,... for the record, I'm American and I'm not Asian, Chinese is not my native language obviously, so no correctness guaranteed.
