The incoming data received by the client can be an incomplete frame (or may
be more than one frame, since the data is not organized as the same as you
wrote at server end), so you can not decode it directly.
Use function av_parser_parse2() first to get complete frame one by one from
the incoming da
Hi Qinfan,
Thank you very much for your hints!
I monitored the sending frames and the receiving frames, and they are the
same. In fact, at the server end, I generate frames one by one, and encode
it, then send it. Therefore, at the client end, they must be received one
frame by one frame. So I th
Hi,
If i am right, got_picture_ptr should be zero in my case because i send one
frame each time. While there are bad pointers in picture->data, do you have
any idea?

I guess the data may be audio frame, not video frame. The data should be
filtered before sending at the server end.

Thank you Hung, Nguyen Viet ,
I've added these 32 bits headers, but it does not work. my program at
server end is something like this:
int saveFrame(void *ctx, unsigned char *pixels, int frameWidth, int
frameHeight, unsigned char **out, int *len)
{
Ctx *c = (Ctx*)ctx;
// convert RGB colorspace i
Hi,
It seems you got some mistakes in your code.
1- In your conversion colour space code, not all stride is frameWidth. For
YUV420p, stride for Cr, Cb is frameWidth/2
2- After you call x264_encoder_encode, you should call x264_nal_encode
3- When send data to ffmpeg h264 decoder, remember that is a
Thank you very much sir!
I solved my problems according to your suggestion!
While I have to point out that:
1. for the four bytes header, it is automatically added if we set
*param.b_annexb
= 1*, and 0 while add the size of frame, so we don't need to add it
manually. (Don't forget to set *param.b_
