FFMPEG 안드로이드 HW 인코딩 (MediaCodec)

안녕하세요. 도정진입니다.

벌써 2월 20일이 되었네요. 시간이 너무 빠르게 흘러갑니다. 정신없이 흘러가네요.

작년 중순쯤에 안드로이드에서 MediaCodec 을 통한 하드웨어 인코딩을 할 수 있지 않을까? 하는 고민으로 정보 서칭을 하며 이렇게 시간이 흘러왔습니다.

FFMPEG 에서 mediacodec 을 Enable 하면 빌드가 가능하다는 것을 알고 있었지만, 당최 미디어 코덱에 관련한 글은 어디에도 보이지가 않았습니다.

실제로 카카오톡으로 영상을 전송할 경우 인코딩을 누가 담당하는지 모르겠습니다만, 저화질로 인코딩되어 전송된다는 점... 실제로는 서버에 전송하여 인코딩이 일어나는지는 정확히 모릅니다.

카메라 데이터를 받아서 동영상 파일로 저장하는 것 모두 안드로이드쪽 미디어코덱을 사용하는 것으로 알고 있습니다. 이전에 U5PVR 에서 OMX 코덱을 검사할 때 MediaCodec Info 앱을 사용해본적이 있습니다.

https://play.google.com/store/apps/details?id=com.ellevsoft.mediacodecinfo

이 앱을 사용하여 OMX 코덱들을 살펴보면 아래처럼 나타납니다. 인코더가 존재하는 것입니다.

실제적으로 OMX.google.h264.encoder 는 SW 인코더이고 HW 인코더는 OMX.Exynos.AVC.encoder 입니다.

이 인코더를 실제 영상을 인코딩하는 데에 사용할 수 있지 않을까 하고 고민을 많이 했습니다. 고민하고 테스트한 결과를 지금 말씀드리겠습니다.

1. 쉴드 PLEX 서버 / Android Emby 서버

실제로 쉴드를 트랜스코딩용으로 구매하시는 분들이 굉장히 많습니다. 내부의 엔비디아 테그라 TX1 의 APU 를 통해 인코딩이 매우 잘 되기 때문입니다.

맥스웰 그래픽을 기반으로 PLEX 서버에서 인코딩이 매우 만족스럽게 작동합니다.

이전에도 어떻게 안드로이드 기반에서 인코딩을 진행할지 매우 궁금했습니다. 쉴드를 구매하고 나서 직접 테스트를 해본 결과 몇가지 코덱은 하드웨어 인코딩이 작동하지 않았지만, 특이한 점은 프로세스에 MediaCodec 이 올라온다는 점이였습니다.

그때 당시에는 왜 이렇지? 라는 생각을 많이 했었습니다.

최근에 오락실아들님이 Emby Server 의 Fork 버전을 올려주시면서 트랜스코딩에 MediaCodec 이 있는것을 보게 되었습니다.

그래서 Emby Server 를 실제로 설치하여 안드로이드에서 트랜스코딩을 해보게 되었습니다.

테스트 장비는 U5PVR 입니다. Emby Server 앱을 설치하면 그대로 Emby Server 가 동작합니다.

트랜스코딩 설정에서 하드웨어 디코딩 인코딩과 관련하여 코덱 선택을 할 수 있습니다.

2. 커맨드 라인 로그

트랜스코딩을 할 때 아래와 같은 프로세스가 올라옵니다.

실제 속도를 측정해 보기 위해 /data/data/com.emby.embyserver/files/ffmpeg 폴더 내부의 ffmpeg 를 실행하여 직접 사용해 보았습니다.

이 ffmpeg 는 libemby 라이브러리를 사용합니다. 이 라이브러리는 현재 안드로이드 6.0 7.0 8.0 을 지원하며, 안드로이드 9 에서는 테스트가 불가능합니다.

Encoder h264_mediacodecndk [H.264 MediaCodec NDK]:

General capabilities: delay

Threading capabilities: none

Supported pixel formats: nv12 yuv420p

h264_mediacodecndk_class AVOptions:

-mediacodec_name <string> E..V..... Name of the MediaCodec codec to use

-rc-mode <int> E..V..... The bitrate mode to use (from 1 to 2) (default vbr)

vbr E..V..... Variable bitrate

cbr E..V..... Constant bitrate

-mediacodec_output_size <image_size> E..V..... Temporary hack to support scaling on output

-is-rtk <boolean> E..V..... Whether the encoder is Realtek's (default auto)

옵션을 확인해본 결과 미디어코덱 지정 / vbr cbr 선택 / 아웃풋 사이즈 / 리얼텍 인지 확인하는 부분 이 있습니다.

실제로 -mediacodec_name 은 지정하지 않아도 알아서 잘 찾아서 선택합니다. 그런데 직접적으로 문제가 있는 부분은 -mediacodec_output_size 가 동작하지 않습니다.

쉴드에서 잘 동작하는지 모르겠으나 실제로 작동하지 U5PVR / 갤럭시S7 / 포코F1 에서 작동하지 않습니다.

3. 타 기기에서의 테스트

1. 갤럭시 S7

상기처럼 에러가 발생하며, 인코딩 부분은 libx264 의 소프트웨어 코덱으로 대체됩니다.

2. 포코폰 F1

해당 서버 앱이 안드로이드 9 라이브러리를 제공하지 않아서 트랜스코딩이 정상적으로 작동하지 않습니다. 따라서, 이 부분을 해결하기 위해 멀티롬 기능을 통해 포코폰F1 의 초기롬 안드로이드 8.1 을 설치하였습니다.

(멀티롬의 경우 운영체제 버전이 달라도 잘 작동하네요.)

상기에도 마찬가지로 mediacodec_output_size 옵션이 1280x720 으로 들어가고 있고, NDK 관련 로그에서도 1280x720 으로 확인되고 있습니다만, 영상 출력은 원본 소스와 같습니다.

혹시나 VP9 Apink4k 영상 테스트 해보았습니다. 힘들어합니다. 인코딩 출력도 3840x2160 이다보니 속도가 많이 떨어집니다.

4. 아쉬움

실제로 하이실리콘 CV200 제품의 경우 VPU 에서 하드웨어 인코딩을 지원합니다만, 이게 OMX 쪽으로 연동이 되어있지 않은것 같습니다. 정말 아쉽습니다.

그리고 아직 ffmpeg 에서 미디어코덱을 완벽히 지원하지 못하고 있습니다.

혹시 버전이 낮아서 발생하는 문제인지 체크를 하기 위해, NDK 로 ffmpeg 를 빌드해보고 있습니다.

차후에 개선된 글로 찾아뵙겠습니다.

감사합니다.
