decoding mpeg4 raw data with CMMFDevVideoPlay

[casual_kumar]

Hi,

I am trying to decode mpeg4 raw data with CMMFDevVideoPlay. I have used mime type video/mp4v-es. However, when I copy the packets into the decoder it leaves with KErrCurrupt.

Do the packets need to have RTP headers/footers for this mime type? I have configured the decoder with this header:
TVideoPictureHeader header = {0};
header.iProfile = 0;
header.iLevel = 3;
header.iVersion = -1;
header.iSizeInMemory.iWidth = 320;
header.iSizeInMemory.iHeight = 240;
header.iDisplayedRect.SetRect(TPoint(0,0),TSize(320,240));

Any ideas?

you may try profile-level id as 4 with video/mp4v-es, instaed of 3. if it is in form of video/mp4v-es.

As I understand the mime type that I have used corresponds to MPEG4 raw data (please do correct me if I am wrong).

While passing the raw data, should I put any headers/footers (RTP for example???) for the decoder to successfully understand the packet? Each packet is supposed to have one of I or P complete frames.

I changed
header.iLevel = 4;

still same currupt packet leave is occurring. I have selected a decoder enumerated with mime type in the following way
iDevVideo->FindDecodersL(_L8("video/MP4V-ES"), 0, decoders, ETrue);

does the string passed need to have any other info for selection of correct decoder?
