If you don't have time to read the details below, here is a quick tip :
The values on the 2nd line must be around 0 in normal circumstances.
(otherwise there might be a problem with codecs or signal reception)
Details:
DIRECTSHOW RELATED COUNTERS:
Frame Rate: the average frame rate achieved.
higher is better (some codecs limit this value at 25 fps while some others let it to be higher)
Jitter: Expresses the average time between successive frames delivered to the video renderer.
lower is better (normally should be 0)
Dropped: the number of frames dropped by the renderer.
lower is better (normally should be 0)
* These values (Frame rate, jitter and dropped) are taken from the renderer. Some codecs might cause renderer to return wrong values.
V Requests: Video sample requests of the video codec. -1 means codec stopped. The value should always be increasing after tuning to a channel. This could stop increasing if channel is scrambled/ couldnt be descrambled or there is no video/audio data incoming or codec crashed ("Reset DirectShow" or retuning to the channel might help in most cases)
A Requests: the same as above , for Audio
DS Resets: How many DirectShow-resets have been occured due to buffer overflow.
STREAM/SIGNAL RELATED COUNTERS:
Packet Losses: How many continuity errors detected on the incoming stream. This is the reason for most of the picture freezes and glitches. Caused by weak signal level or a warmed up tuner (!)
Signal Losses: How many signal losses detected? (actually "how long", this value displays the amount of signal loss in seconds)
T.Breaks: Time stamp breaks. How many timing-breaks have been detected on the video and audio streams. i.e. gaps and wraps in PTS/DTS values. This could happen and quite normal. there could be a problem only if this value goes up too fast.
Received TS: How many TS packets received. This should normally display an increasing value after tuning to a channel, otherwise it means there is a problem in getting the data from the driver, maybe tuner is not capable to demodulate the signal or DD is not capable to process the data on this TP (not a regular DVB stream?)
The value you see next to red/blue buffer bars (gauges) is the total number of the packet sent to video and audio codecs.
have fun!
