Thank you again! :D

1 - Since mencoder and ffvfw both uses libavcodec what differences are you specting find out?
2 - Does mencoder.exe perform same work that ffvfw.dll? 3 - Could ffvfw GUI (control panel) to be used for mencoder.exe (some like rename mencoder.exe to ffvfw.dll)? |

@vmesquita,
More trouble with MencoderME v0.21 GUI. It now hangs up my system using 1 pass or 2 pass. I decided to take my settings from MencoderME GUI and create them in a batch file. Everything ran without any problems. There were some strange results thought. I used dvd2avi (.d2v), avisynth v2.54 motion adapative script (.avs), MakeAVIS or FakeAVIS (.avi) as input to batch Mencoder. Then I used 1cd KVCD target and MakeAVIS filter. I used CalcuMatic to get the bitrate for a 92minute movie for 1 80min CDR with 64 kb audio. The bitrate was 1122. So far no problems. I changed vrc_buf_size=327, vrc_maxbitrate=2500, and vbitrate=1122. My predicted video file size should be 754MB and audio 42MB. I started the batch file and 1 hour 30 minutes later the mpeg-1 file is done. There were some strange results. 1.. During the batch run the following message repeated over 40+ times [mpeg1video@ 0x908410] rc buffer underflow 0mb A-V: 0.000 [0:0] [mpeg1video@ 0x908410] warning, clipping 1 dct coefficients to –255..255 [mpeg1video@ 0x908410] warning, clipping 1 dct coefficients to –255..255 2.. The actual video file size of 448MB was way off from predicted size of 745MB. Is there any way to get this accurate?? Comments: The picture quality was very good this time and the entire movie was there with a file size of 448MB. This batch test was 1 pass. I’d like to try 2 pass and compare quality and file size. I see advantages with batch as being easier to intergrate with a automated process. If there were a batch program with commandlines for MakeAVIS this would be very easy. -BP |

I got similar errors displayed. But I didn't use a batch file. I used a single command line, for test purposes. -kwag |
For some reason, this messages make the GUI hang, no idea why. Well, at least we know this. I'll try to find a stream that generated this kind of message when being encoded to MPEG1. Actually I didn't do any MPEG1 tests till now.
EDIT: @BP The undersize problem should have to do with that "can't quantisize less than this" problem. Maybe we should use a slower scplx_mask with mpeg1. This needs to be tested. So far most optimization was done with MPEG2. EDIT2: I think I found the MPEG1 problem. The messages to the error output stream (stderr in C++) were not being redirected. I already added this for the next version and now the GUI is showing "[mpeg1video @ 0x940380]warning, cliping 1 dct coefficents to -255..255" and continuing. I hope this fix works for everyone. :D |
@Kwag,
BTW, in calculating Bitrate, I checked Moviestacker, CalcuMatic, MPEG-1 bitrate calculator, MEncoderME GUI and the DVD movie jewel case. CalcuMatic was the most accurate: DVD Movie: The Transporter Movie Time: 92 minutes 8 seconds CalcuMatic: Time: 92 min 8 sec Moviestacker: Time: 90 min 20 sec MEncoderME GUI: Time 90 min MPEG-1 bitrate calculator: Time: 90 min 22 sec Note: In some of these programs a .d2v file is being read to get the time and this may be why bitrate varied from 1073 to 1158. If file size prediction relies on an accurate bitrate, CalcuMatic is a winner :wink: -BP |
@vmesquita,
Why not let the batch process display these messages instead of capturing this display to a window. I wanted to add some suggestions and wish options to MEncoderME v0.2x next release :wink: 1) Select output file name 2) Extend audio bitrate range to include 64, 80, 96, ....etc 3) PC Shutdown check box This would add a shutdown program at the end of the batch file 4) Movie Time is not showing correctly where is it derived?? 5) target 1cd KVCD should be changed for vrc_buf_size=327 BTW, what does Overhead represent (i.e. multiplex size) EDIT- If it's possible could a batch file be created and saved for execution so I can retry the run in batch. This is handy for debugging. Otherwise I have to re-enter everyhing in MEncoderME to try again :) Thanks -BP |

Another suggestion:
A button to clear log . |

Hi everyone,
0.22 is out! What's new: - preview filters/crop options/resize using MPlayer throught a nice preview button - Crop added. Now overscan is possible. - Deinterlace via KernelDeint added - Clear Log button - MPEG1 crashing should be solved. - command-line is saved as "encode.bat" Get it here: http://www.jltoca.uaivip.com.br/files/MencodeME022.zip You also need to put a mencoder and mplayer (for preview) binary in the same folder. You can use this one: http://www.jltoca.uaivip.com.br/file...40423-0019.zip |
Você é uma máquina de programação do car****!!!!
(Translation: You are a fuc....(friendly sense) programing machine!!!!) :D :D :D :D :D :D :D :D Note: Edited by Mod. due to used terms in Portuguese |
Hi Prodater,
I'm sorry but I had to edit your post. Not that we see so many Portuguese speaking members, but we have to keep our maners. Anyway now that it's fixed I have to say :arrow: I completely agree with you :!: :lol: VM really is #$%#% programming machine :D I just hope he keeps his pace. Soon we'll have a GUI with all sexy options of MEncoder :wink: Thanks V: you're da man :!: :D Cheers |
@ rds: :wink:
@ VM: Not really very important but, did you forget mplayer in you dist file? |

Hi all,
This new mplayer that comes with 040423-0019 by VMesquita is funny. Sorry VM. You're probably not responsible for that :wink: Anyway it seems it's now using OpenGL to play my movies. But it is way slower than previous builds and it says it is doing a YV12 :arrow: RGB colorspace convertion. Well sometimes to take a step forward they have to take a step backwards...the price we pay for building technology :lol: And my VGA card is already a bit outdated: nVidia TNT2 :( Anyway I always wondered: how do they put that nice icon on mplayer executable file :roll: :?: Eheh. I guess I'm not cut out for compilings :lol: Cheers |
