VDR starts each file with an I-frame:
bool cRecorder::NextFile(void)
{
if (recordFile && frameDetector->IndependentFrame()) { // every file shall start with an independent frame
if (fileSize > MEGABYTE(off_t(Setup.MaxVideoFileSize)) || RunningLowOnDiskSpace()) {
recordFile = fileName->NextFile();
fileSize = 0;
}
}
return recordFile != NULL;
}
