Hi,
I am writing DirectShowMP4 decoder filter using UMC::Mpeg4VideoDecoder (IPP 5.2 beta along with the correspondent media samples).
The problem is that MPEG4VideoDecoder::Init() always returns UMC_NOT_FIND_SYNCWORD
I checked the first frame data which is passed in
BaseCodecParams *lpInit. At the beginning I have 0, 0, 1, 182, which looks like the start marker of the frame. Maybe the problem is that my decoder filter is connected to MP4Splitter.ax.
When I play my ".m4v" files using UMC::AVSync it works fine. But in debugI see that the first frame of the same file which goes to MPEG4VideoDecoder::Init()is differ, it starts with 0, 0, 1, 176, etc...
I appreciate any advise
Anton
PS. I play m4v files which I creates using UMC::MPEG4VideoEncoder. First, I tried to forget about DirectShow and use UMC::AVSync for replay in my application, but UMC::AVSync::SetPosition method doesn't work at all I don't know why.
