| /** |
| * The following API around MediaCodec and MediaFormat is based on the |
| * NDK one provided by Google since Android 5.0. |
| * |
| * Differences from the NDK API: |
| * |
| * Buffers returned by ff_AMediaFormat_toString and ff_AMediaFormat_getString |
| * are newly allocated buffer and must be freed by the user after use. |
| * |
| * The MediaCrypto API is not implemented. |
| * |
| * ff_AMediaCodec_infoTryAgainLater, ff_AMediaCodec_infoOutputBuffersChanged, |
| * ff_AMediaCodec_infoOutputFormatChanged, ff_AMediaCodec_cleanOutputBuffers |
| * ff_AMediaCodec_getName and ff_AMediaCodec_getBufferFlagEndOfStream are not |
| * part of the original NDK API and are convenience functions to hide JNI |
| * implementation. |
| * |
| * The API around MediaCodecList is not part of the NDK (and is lacking as |
| * we still need to retrieve the codec name to work around faulty decoders |
| * and encoders). |
| * |
| * For documentation, please refers to NdkMediaCodec.h NdkMediaFormat.h and |
| * http://developer.android.com/reference/android/media/MediaCodec.html. |
