Android的媒体codeC的HEVC [英] Android MediaCodec for HEVC

问题描述

我在寻找到使用Android的媒体codec类脱code HEVC。有没有对项目做任何的例子？

I'm looking into using the android MediaCodec class to decode HEVC. Are there any examples of projects that do this?

在present我配置去codeR具有以下内容：

At present I configure the decoder with the following:

AMEDIAFORMAT_KEY_MIME: "video/hevc"
AMEDIAFORMAT_KEY_MAX_HEIGHT: 4320
AMEDIAFORMAT_KEY_MAX_WIDTH: 8192
AMEDIAFORMAT_KEY_HEIGHT: 1600
AMEDIAFORMAT_KEY_WIDTH: 3840
AMEDIAFORMAT_KEY_FRAME_RATE: 24
AMEDIAFORMAT_KEY_PUSH_BLANK_BUFFERS_ON_STOP: 1

在使用这个设置，我没有得到任何视频输出。我也试着设置 CSD-0 ， CSD-1 和 CSD-2 到VPS，分别为SPS和PPS，但没有运气。

When using this setup, I get no video output. I've also tried setting csd-0, csd-1 and csd-2 to the VPS, SPS and PPS respectively, but have had no luck.

我得到在控制台下面的错误，但已经保证了它是不相关的：

I get the following error in the console, but have been assured it is unrelated:

01-19 15:40:36.048: E/OMXNodeInstance(17230): OMX_GetExtensionIndex OMX.google.android.index.storeMetaDataInBuffers failed
01-19 15:40:36.048: E/ACodec(17230): [OMX.google.hevc.decoder] storeMetaDataInBuffers failed w/ err -2147483648

我发现， dequeueOutputBuffer 总是返回 1 。看来，已排队通过 dequeueInputBuffer 将返回指数queueInputBuffer 他们是从获得前dequeueOutputBuffer 。

I have found that dequeueOutputBuffer is always returning -1. It appears that dequeueInputBuffer is returning indices that have been queued by queueInputBuffer before they are obtained from dequeueOutputBuffer.

有没有人设法去$ C C HEVC视频的Andr​​oid？

Has anyone managed to decode HEVC video on Android?

推荐答案

这个问题似乎是与分辨率 - 512x216没有工作，给了上述症状，但1920x800的罚款。我问过<一个href="http://stackoverflow.com/questions/28068537/android-media$c$cc-hevc-supported-resolutions">another什么是支持的分辨率问题。

The problem seems to be with the resolution - 512x216 didn't work and gave the above symptoms, but 1920x800 worked fine. I've asked another question about what resolutions are supported.
