[FFmpeg-devel] ffv1 to h264 : "Error while decoding stream #0.0"

[Janne]

Hey,

I'm transcoding from mencoder ffv1 (w/ pcm audio) output to mp4 (h264
& libfaac) with ffmpeg but it halts (non-idle) to errors (see below).
There's no problems with smaller files though.

Here's the ffmpeg command commented:

ffmpeg -i ffmpeg-input-file-1.8Gb.avi \
-s 320x240 -r 30 -b 900k -vcodec h264 \
-acodec libfaac -ab 96k -ac 1 -me_method full  -y \
output_file_which_halts_at_123Mb.mp4

The mencoder command to produce the input file above:

VF="pp=ac,hqdn3d=9:9:9,eq2=2.6:1.24:0.1"

mencoder mjpeg_file_from_camera.avi \
-oac copy -ovc lavc -lavcopts vcodec=ffv1:vstrict=-2 \
-vf pp=ac,hqdn3d=9:9:9,eq2=2.6:1.24:0.1 \
-o ffmpeg-input-file-1.8Gb.avi


Any ideas how to correct or proceed? My goal is to compress mjpegs
from my camera to mp4 with h264 & aac and us the video filters of
mencoder (hqdn3d especially). Mencoder seems to be somewhat unreliable
to produce files that have video and audio in sync (except if you use
lavc codec for both video and audio).
