示例1: GetRecordingFrameRate
float PVRClientMythTV::GetRecordingFrameRate(MythProgramInfo &recording)
{
// MythTV uses frame offsets whereas XBMC expects a time offset.
// This function can be used to convert the frame offsets to time offsets and back.
// The average frameRate is calculated by: frameRate = frameCount / duration.
float frameRate = 0.0f;
if (g_bExtraDebug)
{
XBMC->Log(LOG_DEBUG, "%s - Getting Framerate for: %s)", __FUNCTION__, recording.Title(false).c_str());
}
// cmyth_get_bookmark_mark returns the appropriate frame offset for the given byte offset (recordedseek table)
// This can be used to determine the frame count (by querying the max byte offset)
long long frameCount = m_db.GetBookmarkMark(recording, LLONG_MAX, 0);
if (frameCount > 0)
{
if (g_bExtraDebug)
{
XBMC->Log(LOG_DEBUG, "%s - FrameCount: %lld)", __FUNCTION__, frameCount);
XBMC->Log(LOG_DEBUG, "%s - Duration: %d)", __FUNCTION__, recording.Duration());
}
if (recording.Duration() > 0)
{
// Calculate frameRate
frameRate = (float)frameCount / (float)recording.Duration();
if (g_bExtraDebug)
