Audio Problem

[chits007]

Hi ,
I put a MPEG2-TS which has AVC(h.264) video and AAC(ADTS) Audio .
Firstly the audio doesn't comes up.Do i need to install proper audio codecs.

For h.264 i installed a decoder so i am able to see video.


Next I have a TS file ,I extracted .264 data datat and then if  i create a TS stream from raw h.264  ,XMuxer pro  gave me the
   PES-Data_Alignment_ flag  is set to false
while in the orignal TS file it was set to 1 when a video start code was there.

Please shed some light on it.

Hi,

Yes, you need to install AAC audio codec.

Could you tell me what you mean under "PES-Data_Alignment_ flag"? Unfortunately this term is unknown for me.

Hi,
XMuxer pro should create  Mpeg2-TS compliant stransport stream from raw data.I have given XMuxer Pro a raw h.264 file and now i am trying to create a TS file.The software create Mpeg-TS file but it doesn't mark PES_ALignment bit.

Pes_Alignmnet_bit[See Page 35 of H.222 for more detail]-This flag tells that Video Start code immediately follow .

Unfortunately the XMuxer pro set this to 0 while in the orignal TS it was 1.

Thank you for your detailed explanation. Actually current version of Elecard Multiplexer not handles flags that you described. We'll fix this issue as soon as possible.

Sorry for inconvenience.

We've fixed Pes_Alignmnet_bit issue in the Elecard Multiplexer. After some testing we'll update it in all our products.
