Android的媒体codeC HEVC支持的分辨率 [英] Android MediaCodec HEVC Supported Resolutions

问题描述

有谁知道支持的分辨率是Android的媒体codeC的解码HEVC什么时候？

Does anyone know what the supported resolutions are for Android MediaCodec when decoding HEVC?

经过反复试验，我发现了以下工作：

Through trial and error I've found that the following work:

640x272
720x304
960x400
1280x528
1920x800
2560x1072

和以下别：

512x216
3840x1600

有没有官方文件？

Is there any official documentation?

推荐答案

我怀疑有任何官方文档 - 在实践中，你也许可以依靠的事实，即由CTS工作测试的决议，但其它决议可以表现在任何方面。

I doubt that there is any official documentation - in practice, you can probably rely on the fact that the resolutions that are tested by the CTS work, but other resolutions can behave in any way.

媒体codeC来看对HEVC ，我猜你与它只有拿到了SW德codeR设备测试。实际上我想，真正的硬件去codeRS会更有能力或更兼容，比SW德$ C $铬。 （这听起来可能有悖常理，但是这是特别EN codeR，这是非常有限的H264 SW历史情况）。

Judging from Android MediaCodec for HEVC, I guess you're testing with a device which only has got the SW decoder. I would actually guess that the real HW decoders would be more capable or more compatible, than the SW decoder. (This may sound counterintuitive, but this is especially the case historically with the H264 SW encoder, which is very limited.)

第一非工作分辨率具有的高度是不会被16整除（所有工作决议具有宽度和高度由16可分割），而另外一个可能是过大。这是否假说似乎托起，如果你测试更多的决议？

The first non-working resolution has a height that isn't dividable by 16 (all the working resolutions have both width and height dividable by 16), while the other one might be "too large". Does that hypothesis seem to hold up if you test more resolutions?
