Hi,
I'm a n00b on a lot of things here: MPEG-2, FFMPEG and this forum

I also registed on another forum:
http://dvdripping-guid.berlios.de/fo...wforum.php?f=2 and I'm willing to hear about other good resources for MPEG-2 encoding under Linux.
My previous experience is MPEG-4 and Avisynth in Doom9, particularly automatic IVTC procedures. None of this needed for MPEG-2
Now let's get to the point.
From what I could check so far it seems that FFMPEG-based encodings are about 4 times faster than mjpegtools-based encodings, and quality seems nice too, compared with TMPGEnc. The main problem about FFMPEG current build is not respecting the maximum bitrate and still needs some improvement on motion estimation.
All of this is in Michael's TODO list:

Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
-------------------
- finish implementation of WMV2 j-picture
- H264 encoder
- H264 deblock filter
- H264 B frames
- H264 CABAC
- per MB ratecontrol (so VCD and such do work better)
- more optimizations
- simper rate control
- split h263.c
- mpeg2 encoding (after the ME impovements)
- format idependant quality parameter

It seems that Michael has a lot more work to do on the H.264 part and may be more interested in knowing better this new codec than to enable 4 times faster quality MPEG-2 backups using open-source tools that work according to specifications
I'd like to know if anyone has tried FFMPEG MPEG-2 encoding under FreeBSD, if there are any new developments on the max bitrate problem, and if there is any way to use a requantizer tool like M2VRequantizer to post-process the FFMPEG output that overlaps max bitrate.
Cheers to all,
Bilu
