 |
|
I am trying to encode a video using mencoder:
| Code: |
mencoder /home/user/documents/videos/Survivorman\ Season\ 1/102SonorannDesert.mp4 -oac lavc -lavcopts acodec=ac3:abitrate=96 -ovc lavc -lavcopts vcodec=mpeg4:vqscale=5:vpass=2:aspect=4/3:vbitrate=512 -of lavf -lavfopts format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -o /home/cvance/Desktop/out.mp4
|
and I get the following output:
| Code: |

I wish I knew more about what the error means, but I get no information. Can anyone help me figure out what is wrong? |

I wish I could do just an avi, but I need mpeg4 for my ipod. ffmpeg works well for it but it cannot decode my realplayer files, which I need. Mplayer can play rmvb files so I assume, naturally, that it can decode it as well. I tried moving the -lavcopts into one line as such:
| Code: |
mencoder /home/cvance/documents/videos/Survivorman\ Season\ 1/102SonorannDesert.mp4 -oac lavc -ovc lavc -lavcopts acodec=ac3:abitrate=96:vcodec=mpeg4:vqscale=5:vpass=2:vbitrate=512:autoaspect -of lavf -lavfopts format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -o /home/cvance/Desktop/out.mp4
|
I still get the same error:

Is the command line that you posted for your first encoding pass? If so you should change vpass=2 to vpass=1. |

| Yes, that was the solution, but I need to do an experiment with 1 vs 2 pass encoding to see if the additional overhead is worth the increased efficiency. |
