Hello, I am a new user of ffmpeg. Want to know what is the command for doing A/V sync, where my encoded video is H.264 format and Audio is AAC format. I am using Msys for doing this. My requirement is the synchronization shall not exceed 100 milliseconds between the audio and video streams. What are the other aspects I should take care for doing A/V sync (what are the options should be used in the command)? Please help me...
Thanks, Ananya ________________________________________ From: [email protected] Behalf Ofsq.cheng Sent: Wednesday, March 16, 2011 1:11:28 AM To: Libav* user questions and discussions Cc: kumar.pavan463; [email protected] Subject: Re: [libav-user] how to synchronize the audio and video in .flv About A/V sync playback, please read ffplay.c, it's a good sample.
