I am trying to use ffmpeg to convert an avi to mpg (mpeg 2). This command works on the CLI in Windows, but is failing on my Linux box. Can someone help me decipher what is wrong?

Command:

ffmpeg -i VIDEO_FILE_IN -hq -target ntsc-dvd -b 6000 -aspect 4:3 -s 720x480 -acodec mp2 -ab 224 -ac 2 -mbd 2 -qmin 2 -async 1 -y VIDEO_FILE_OUT

Error:

ffmpeg: motion_est.c:1961: ff_fix_long_p_mvs: Assertion `range <=256 || !(s->codec_id == CODEC_ID_MPEG2VIDEO && s->avctx->strict_std_compliance >= 0)' failed. Aborted

Thanks, Eric

Please post the *full* output messages on both platforms.

HaND,

1. I have a dvb-t tv interface. It works fine (on linux) with mplayer and xine, but i have not been able to find a way to let it capture to a mpeg file. cam some one be of help, pointing me to a good readme ? 2. using winXP with the same setup i got sono recordinmg losing some par of the stream, both on video and audio. playing back, either under windows or on linux, with any program althopught there are some errors in the video and gaps in the audio the overall recording remain in sync. I thred to use ffmpeg to recode in a more compact way, but i ended in having the audio without the gap, so gradually losing the sync with the video. Hov can i recode without losing sync ?

either mplayer -dumpstream -dumpfile recording.ts dvb://TV_CHANNEL or mplayer -oac copy -ovc copy -of mpeg -mpegopts format=dvd -o recording.mpg dvb://TV_CHANNEL -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Telefona con Email.it Phone Card, tanti minuti di conversazione con il massimo del risparmio, clicca qui Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=2687&d=7-11
