[Ffmpeg-devel] Get 1 frame bitstream without decoding.

[Ahmad Zaidee bin Abu]

Hi all,
 
How do I get bitstream (frame by frame) of compressed video without decoding it?
I see example as below has frameFinished indicator, to indicate the end of frame, but 
how do I get the whole 1 frame without decoding (bitstream) or passing the frameFinished ?
 
while(av_read_frame(pFormatCtx, &packet)>=0)
{
// Is this a packet from the video stream?
if(packet.stream_index==videoStream)
{
// Decode video frame
avcodec_decode_video(pCodecCtx, pFrame, &frameFinished, 
packet.data, packet.size);
// Did we get a video frame?
if(frameFinished)
{ ... }
 
Thanks in advance.
