Hello,
Ok. I have to explain my problem in more details:
I use the example code from the dranger-tutorial. How I said, it works for
ordinary mpeg2-ts-files. My own readFrame - method looks like the following:
bool CAVFile::readFrame(int& filenr, AVPacket* packet)
{
if (filenr == -1)
filenr = mSelectedFileIndex;
if (filenr != mSelectedFileIndex)
{
setSelectedFile( filenr );
}
if (av_read_frame(mPFormatCtx, packet) != 0)
{
...
}
return true;
}
As you can see, I use the av_read_frame-function to get all the frames. Later
I proof, if it is a videoframe with the streamID.
if (packet.streamID == mStreamID)
...
Only with ts-files containing a h.264 coded videostream I get these curious
errormessages (down below). Do I have to do more than described by the
drangertutorial? I can't find any errors and mplayer seems to work ok with my
ts-file.
Thanks.
regards,
Sven
