TI-Sitara FFmpeg Codec과 SDK 구조 및 성능 (참고용)

1. Sitara에서 제공해주는 FFmepg Codec

Sitara인 경우, Hardware Codec이 존재하지 않기 때문에, Soft Codec인 FFmpeg을 사용을 한다.
OpenMax에 FFmpeg을 추상적으로 연결하여, 한번더 걸쳐 사용도 가능하게지만,
Gstreamer에서 FFmpeg도 직접 지원되는 것 같다.

FFmpeg을 보니, LGPL, GPLv2, GPLv3 그리고, 다른 licenese를 가지고 있어 좀 복잡한것 같다.
법적인 Lincese는 아래를 참조하자
(사실 Chip 업체에 물어보는것이 제일 빠른것 같다, 골치 아프다)

  • 상위 정보에 대해서 

상위 정보는 아래의 사이트에서 가져왔지만, TI가 wiki를 최신정보로 인해 삭제하고 있는것 같아,
언제 삭제할지 몰라 그대로 많은 부분을 가져왔다. TI에서도 언급을 했지만, 참고용으로만 사용하라고 했으며,
성능도 역시 신뢰를 할수가 없다.
그리고, Gstreamer 사용법도 소개가 되었지만 역시 SDK가 변경이 되면서 version 달라지면서 동작이 제대로 안되는 부분이 있다.
