FFmpeg options ? Bad result on a standalone

[Umen Pich]

Hello friends,

I am not very familiar with the ffmpeg options, but apparently something wrong goes on, because when I convert to xvid by ffmpeg (WinFF frontend) the result misbehaves on my standalone player (RJ-1000).
Precisely - after playing for example the first 20 seconds it freezes the picture, while the sound goes on... then after another maybe 15-20 seconds the video will start playing OK (yes synchronized with the audio, which simply means that you skip parts of the video). Then after a while - the picture freezes again.
If I encode by using Virtualdub this problem never happens.
The problem is - I cannot always use Vdub, for example if the input is a .flv file.

Here is an example of the settings coming from WinFF:
"C:\Program Files\film_utils\WinFF\ffmpeg.exe" -threads 2 -i "C:\aaa\steven_jobs.flv" -r 30 -vcodec libxvid -vtag XVID -s 720x400 -aspect 16:9 -maxrate 1800k -b 800kb -qmin 3 -qmax 5 -bufsize 4096 -mbd 2 -bf 2 -flags +4mv -trellis -aic -cmp 2 -subcmp 2 -g 300 -acodec libmp3lame -ar 48000 -ab 128k -ac 2 "c:\aaa\\steven_jobs.avi"
pause


Any advice is very welcome !
Thank you!

use latest Virtualdub with flv plugin-it can load flvs
with other plugins, it can load wmvs, mpeg2 and mov. also has directshow plugin which lets you load practically everything
Linx to plugins(except directshow) are on the videohelp page for virtualdub.

I would try it without bframes (take off -bf 2 from the command line).

try with this
"C:\Program Files\film_utils\WinFF\ffmpeg.exe" -threads 2 -i "C:\aaa\steven_jobs.flv" -r 30 -vcodec libxvid -vtag XVID -s 720x400 -aspect 16:9 -maxrate 1800k -b 800kb -qmin 2 -qmax 5 -bf 1 -flags +4mv -trellis -aic -g 150 -acodec libmp3lame -ar 48000 -ab 128k -ac 2 "c:\aaa\\steven_jobs.avi"

shorter gop, less b frames, less qpmin

also has directshow plugin which lets you load practically everything

Including the .lnk shortcut files themselves.
