It'll be set to one if the decoder actually decoded a frame. Due to reordering there might be a delay before you start getting frames. This also means you have to flush the decoder when you're at EOF. > secondly, can i get information regarding number of bytes of decode > buffer > (AVFrame)? The decode function takes care of that for you. Just pass it a pointer to an AVFrame initialized by avcodec_get_frame_defaults(). To be precise, you have to allocate the AVFrame struct (as a stack var would be easiest) but lavc takes care of allocating the buffers it points to. /Tomas
