FLY2000 TV 影音同步大法?? use internal audio ADC at capture

引用:

Philips SAA7133, SAA7134, SAA7135 support audio decoding via internal audio ADC. The program FLY 2000 TV allows to capture audiostream via internal audio ADC. This allows to best syncronize audio and video. Also, these chips support hardware lock audio PLL to video stream. If you have this chip, always use this unique capability.

Question: At capture AVI, the audio and video streams not synchronized.
Answer: The causes of audio/video mistiming, because audio and video stream is captured two different devices - videodecoder and sound card. Try to set a sound format to PCM. Some sound cards, such as Sound Blaster Live! provide synchronisation only at sampling rate 48000 Hz. Select a videocodec and its parameters so that the CPU loading was not higher than 90%. Not recommended to set the highest priority in settings. Try different values of parameters "Interleaving", "Master stream AVI Mux". If these actions was not help, try to enable option "Auto adjust audio speed for match video speed". If you have Philips SAA7133-7135 chip, use internal audio ADC at capture - is a best result .

Philips SAA7133-7135 chip, use internal audio ADC at capture
可是他限制只可擷取32000Hz 16bit stereo
這是Philips SAA7133-7135 chip的限制還是 FLY2000 TV的限制??
