[Libav-user] What is the correct way to read frames

[Oleg]

Yes, you need to flush decoder also.
You had errors while decoding because simple copying AVPacket's data and size no longer works(sorry, it was my fault). It should be like following:

uint8_t *orig_ptr;
ssize_t orig_size;

orig_ptr = pkt.data;
orig_size = pkt.size;

while (pkt.size > 0 && (size = av_decode_video2()) > 0)
{
	pkt.data += size;
	pkt.size -= size;
}

pkt.data = orig_ptr;
pkt.size = orig_size;

av_free_packet(pkt);
