ffmpeg: Fixing delay during capture?

[esoul]

Hello

Well... I need some american news, to be up to date, so I capture it like so

ffmpeg -i http://tvemsnbc-lh.akamaihd.net/i/nbcmsnbc_1@122532/index_1296_av-b.m3u8 -c copy -t 4200 TRMS.mp4

The result can be played on VLC and Daum Potplayer without issues. There is no delay. But if I throw the ffmpeg output at avidemux, then there is a apprx. 500ms delay.

Is there a way to avoid this delay, be setting some option in ffmpeg? Using filters maybe? I think it should be possible, because I captured the stream with the Potplayer, without any issues.


Thanks a lot
Robert
