[MPlayer-dev-eng] A/V sync issues or "too many video packets"

[Bart de Boer]

Dear list,

Sorry for posting this here. I know it's a user problem. But it seems 
nobody really knows what all the options do exactly. So here's my question:

How do I prevent mencoder from compensating for duplicate frames 
(causing A/V desync) without using (buggy?) options like -mc 0 and 
-noskip (which cause "too many video packets in the buffer" errors)?

Is it at all possible? I'm trying to come up with a proper commandline 
for converting H.264 mkv to mpeg4 divx. But all my attempts (and there 
have been many) either cause A/V sync issues or "too many video packets" 
errors.

Here's my latest unsuccessful attempt. Basically -mc 0 and -noskip give 
me good results for some mkv's (H.264 MKV HDTV recordings). But then 
causes "too many video packets" with others (H.264 MKV Blu Ray backups).



nice -n 17 mencoder ${inputFile} \
    -mc 0 \
    -vf softskip,harddup \
    -oac copy \
    -alang eng \
    -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=${vBitrate}:turbo:vpass=1 \
    -ofps 24000/1001 \
    -passlogfile ${logFile} -o /dev/null

Hope someone can help,
