[Libav-user] [libav-user] queuing of avframe

Sorry for formating, it was first message.

Hi

I want to realise AVFrames handling with queue.
My code is

int decode(AVCodecContext *codec_ctx, AVPacket *packet)
{
  AVFrame *frame = av_frame_alloc();
  if (!frame)
    return -1;

  int got_frame;
  int ret = avcodec_decode_video2(codec_ctx, frame, &got_frame, packet);
  if (ret >= 0 && got_frame) {
    /* Allocate buffer references */
    for (int i = 0; i < 3; i++) {
      uint8_t *data = frame->data[i];
      int size = frame->linesize[i] * frame->height;
      frame->buf[i] = av_buffer_create(data, size, av_buffer_default_free, NULL, 0);
    }

    enqueue(frame);
    return 0;
  }

  av_frame_free(&frame);
    return -1;
}

void someFunc()
{
  AVFrame *frame = dequeue();

  ...

  if (frame)
    av_frame_free(&frame);
}

Is it right?

Regards,
