problem while streaming to vlc

[digish_gabhawala]

I am streaming mp4v-es data over RTP and trying ot display the same via VLC player on windows system.

Actually, while sending data, I am fragmenting my VOP of around 4000-5000 bytes to parts of 1400 bytes each and then I am sending that with same timestamp till all fragments are sent.

While playing on VLC, i am getting proper video on top 30% of the screen and remaining part is not proper.

At last there is log-trace from VLC player,


Can anyone please help me that whether i am fragmenting frames correctly? or should I do something else? I am also adding PES header while sending first frame. in PES header, I am putting size as whole frame. Is it correct?

I am not getting what should i do for

illegal dc vlc
or
Error at MB:
kind of messeges?

should I send mpeg4es data directly like this or should I wrap it in mpeg2ts? Please help me as I am new to this field.

Thanks in advance,
Digish
