Hi.
I am trying to implement H263VideoFileSink. But I can't really figure
what is really needed at H263VideoFileSink::afterGettingFrame.
I try to refer from H264or5VideoFileSink::afterGettingFrame.
However, it is different from H263 as H263 doesn't have SPropRecord or SPS.
There is H263plusVideoRTPSink which I may be able to refer to. However,
H263plusVideoRTPSink::doSpecialFrameHandling() is different from
H264or5VideoRTPSink::doSpecialFrameHandling(). So can't really figure
out what is need to be done.
Below is my H263VideoFileSink.cpp file code. H263VideoFileSink is
derived from FileSink
H263VideoFileSink::H263VideoFileSink(UsageEnvironment& env, FILE* fid,
unsigned bufferSize, const char* perFrameFileNamePrefix)
: FileSink(env, fid, bufferSize, perFrameFileNamePrefix)
{
}
H263VideoFileSink* H263VideoFileSink::createNew(UsageEnvironment& env,
const char* fileName, unsigned bufferSize, Boolean
oneFilePerFrame)
{
do {
FILE* fid;
char const* perFrameFileNamePrefix;
if (oneFilePerFrame) {
// Create the fid for each frame
fid = NULL;
perFrameFileNamePrefix = fileName;
} else {
// Normal case: create the fid once
fid = OpenOutputFile(env, fileName);
if (fid == NULL)
{
printf("H263VideoFileSink::createNew fid = NULL\n");
// envir() << "test";
break;
}
perFrameFileNamePrefix = NULL;
}
return new H263VideoFileSink(env, fid, bufferSize,
perFrameFileNamePrefix);
} while (0);
return NULL;
}
H263VideoFileSink::~H263VideoFileSink()
{
}
void H263VideoFileSink::afterGettingFrame(unsigned frameSize,
unsigned numTruncatedBytes, struct timeval presentationTime)
{
envir() << "H263VideoFileSink::afterGettingFrame called\n";
// Call the parent class to complete the normal file write with
the input data:
FileSink::afterGettingFrame(frameSize, numTruncatedBytes,
presentationTime);
}
