Desynchronization Audio/Video MPEG2
Hi!!
I'm capturing some MPEG2 stuff with my DVB card. When I play it in VLC Audio and Video are perfectly synchronizated; nevertheless when I play it in VirtualDubMod audio is a little bit delayed. It's a different delay depending on capture length and channel, so I cannot fix it just delaying audio in the Interleaving section. My final aim is to compress video to MPEG4 and audio to AAC. What can I do?? Why MPEG2 plays OK in VLC and not in VDubMod? Any help is appreciated! |

Although VirtualDubMOD has playback ability, it is primarily a VIDEO EDITOR and shouldn't be relied upon as a player... |

You can automate it by using DGIndex to generate an Avisynth script from a template that contains a DelayAudio() call in conjunction with the __del__ macro. Here is an example template:
vidmpeg2source("__vid__") aud=mpeg2source("__aud__").DelayAudio(__del__) AudioDub(vid,aud) This will serve the audio and video together into VirtualDub and in sync. |

Yeah!! fccHandler's MPEG2 Plugin for VirtualDub works nice!
No desync before and after the compression, perfect!! |
