passing bytebuffer to ffmpeg

[kjhari02]

Hi All,

I'm trying my hands on ffmpeg and am stuck on how I pass the
bytebuffer to the ffmpeg method avcodec_decode_audio3.

The method declaration for is 'avcodec_decode_audio3' is

avcodec_decode_audio3(AVCodecContext *avctx, int16_t *samples, int
*frame_size_ptr, AVPacket *avpkt)

Has anyone done this before.

Can someone throw some light on this?

Regards,
Hari

If your ByteBuffer has an array backend (you created it by the wrap()
static method) you can pass the byte[] array to native code and access
it by JNI's GetByteArrayElements/ReleaseByteArrayElements. Keep in
mind that you should sum the return value of avcodec_decode_audio3 and
keep calling that function until the sum reaches avpkt->size. That's
because in some scenarios there can be more than one audio frame in
one AVPacket.
