[ANNOUNCE] new MPEG muxer in cvs
by Nico Sabbi 18 Jun '06

18 Jun '06

Hi, I have just finishing committing the new code of the MPEG muxer. It's almost completely different from the old one, hopefully much better :) What has changed: - variable muxrate (made badly) has gone - the dreaded APTS < SCR is fixed - images don't freeze anymore nor play at seemingly lower framerate - seeking has largely improved (no more need to wait for audio and video to sync) - the code has been largely generalized, so extending it and adding suport for subs/ multiple audio streams is much easier - all constraints on timings and buffering sizes will be respected, provided that the muxrate is big enough What's still to fix: - it's still possible to have some occasional buffer under and/or ADTS < SCR (strictly related to each other), especially when muxing to xvcd and/or with a large number of b-frames. If this happens the muxer will raise the muxrate and report it, so if you remux using :muxrate=N the problem should vanish; - occasional buffer overflow an/or pts >> scr will be fixed in the next few days Strongly advised: - when encoding video (e.g. without -ovc copy) _always_ use -vf softskip (btw, I have and had a lot of problems with harddup, so I don't use it); - using -ofps is generally quite bad (with the old muxer, too), better use -speed newfr/oldfr (eventually resampling audio) Please, report eventual problems.

Using mencoder to convert files to iPod
by Anthony N. Frasso 02 May '06

02 May '06

I originally sent this message to mplayer-users, but realized it might be more applicable here: Hello, and thanks for your help in advance. I'm attempting to use mencoder to convert movie files I have on my computer to a format that can run on my Video iPod. I am using Mac OS X 10.3, and have installed Xcode 1.5. I've been able to build mplayer using the MPlayer v1.0pre7try2 source, available on the web site. However, I don't seem to have installed the libavformat containers. When I run mencoder -of help, I get the following output: MEncoder 1.0pre7try2-3.3 (C) 2000-2005 MPlayer Team AltiVec found CPU: PowerPC File not found: 'frameno.avi' Failed to open frameno.avi Available output formats: avi - Microsoft Audio/Video Interleaved mpeg - MPEG-1/2 system stream format rawvideo - (video only, one stream only) raw stream, no muxing Exiting... (error parsing cmdline) While these errors bothered me, I went ahead and tried to run the following command: mencoder movie.avi -o movie.mp4 -of lavf -oac mp3lame -ovc lavc. The resulting video does not seem to play. Can anyone here help me figure out what I am doing incorrectly? Thanks again, Anthony Frasso anf4(a)cornell.edu __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Extracting DVD-audio?
by Jay Summet 29 Apr '06

29 Apr '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a friend who has a lot of "I Love Lucy" DVD's, which each have a DVD audio track of the I Love Lucy radio show on them. I can play the radio show on my DVD player, and by using xine and navigating through the menu's, but I can't figure out how to play the audio using mplayer (or extract it to an MP3 via mencoder). Can somebody give me an example command line to play DVD-audio on DVD's? (and explain to me how to find the audio in the first place? e.g. figure out what number to use to extract the audio?) I've tried things like "dvd://#" with lots of different numbers, but that just shows the videos on the DVD's.

help with simple task: crop, scale, encode
by Molle Bestefich 29 Apr '06

29 Apr '06

Hi I'd like to take an input file from a PVR, crop it, scale it to half size, and MPEG4 encode it. It's for a buddy on Windows, so I chose AVI and MSMPEG4v2. First try: # mencoder input.vob \ -vf crop=700:428:8:74 \ -vf scale=350:-2 \ -ovc lavc -lavcopts vcodec=msmpeg4v2 \ -oac mp3lame \ -vo null -of avi -o output.avi It dies with "-vo is not an MEncoder option". Ok, fine (although -vo is in "man mencoder", hmm).

Sound recording problem with SAA7134 TV card and alsa
by Martin Collins 26 Apr '06

26 Apr '06

I am getting strange and unwelcome behaviour when recording from my VCR via the composite input and associated audio sockets on my new MSI TV@nywhere saa7134 TV card. I am using the saa7134-alsa module, not my soundcard. The card has three audio sources: Video,0 - tuner Line,1 - ? Line,2 - composite fly-leads Regardless how my mixer is set mencoder always (initially) records sound from the tuner source, not the audio sockets. Once recording has begun if I toggle the correct source in the mixer then the correct sound is recorded. Most bizarrely, if I start recording (tuner sound), toggle the source (composite sound), then press play on the VCR; mencoder reverts to recording the tuner sound. I have to toggle the source again. It looks like audioid should select the source but when I use it I get no sound at all until I press play or toggle. I am using Debian 2.6.15 and mencoder cvs from today. mencoder -v tv://$1 \ -tv driver=v4l2:device=/dev/video0:input=1:alsa:width=720:height=576:\ chanlist=europe-west:channels=26-BBC1,33-BBC2,23-ITV,30-CHN4,37-CHN5,40-VCR:\ adevice=hw.1:audiorate=32000:amode=1:forceaudio:immediatemode=0:norm=PAL \ -endpos $DURATION \ -ovc lavc -lavcopts vcodec=mjpeg:aspect=768/576 \ -oac pcm \ -mc 0 -noskip \ -vf harddup \ -fps 25 \ -o $3.avi MEncoder dev-CVS-060426-15:17-4.0.3 (C) 2000-2006 MPlayer Team CPU: Advanced Micro Devices Duron/Athlon 4/MP/XP Palomino (Family: 6, Stepping: 2) CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE 91 audio & 204 video codecs init_freetype get_path('font/font.desc') -> '/home/martin/.mplayer/font/font.desc' Font /home/martin/.mplayer/font/font.desc loaded successfully!

Hello. I'm using Gentoo, and has the latest x264 ebuild installed (20060409), but the latest cvs of mplayer can't seem to find it. A few days ago I had no problems activate x264 support. Setting --enable-x264 --with-x264libdir=/usr/lib64/ and --with-x264incdir=/usr/include/ doesn't help. bug? or am I doing something wrong again? Fredrik Eriksson

Filter large dots
by Marco 24 Apr '06

24 Apr '06

Is there a way to filter large dots quickly appearing and disappearing? I'm talking about large (more than 3px) dots with irregular shape. Sometimes they have the shape of a single hair. They are usually present in just a single frame. This kind of noise is very common with old tapes remastered in dvd format. I tried hqdn3d, but I think that it should be used for different noises. Thanks, Marco

Hello. My friend recently sent me a quicktime movie file from his university. I'm supposed to be doing the audio soundtrack for him but I can't get his file to open in anything on my G4. I've been trying various incantations to convert the file on my BSD desktop machine but nothing really seems to work. I can sometimes get output that's watchable on the BSD desktop, but when copied to my PPC G4, it doesn't work at all. I get various strange results such as a completely blank, white movie (Quicktime speak for 'I don't know what this file is) or an empty, black window with extremely strange proportions. MplayerOSX usually gives up on the files entirely and refuses to play them. I've tried this: $ mencoder attemp3.Copy2.mov -o attemp3.Copy2.avi -ovc lavc -of avi -nosound The resulting file plays properly on the BSD desktop but not on the G4, in mplayer or Quicktime Player. The file before conversion: $ file attemp3.Copy2.mov attemp3.Copy2.mov: Apple QuickTime movie (modified) $ mplayer -identify attemp3.Copy2.mov QuickTime/MOV file format detected. -------------- MOV track #0: 183 chunks, 406 samples ID_AUDIO_ID=0 Audio bits: 16 chans: 2 rate: 44100 Audio extra header: len=80 fcc=0x77617665 MOV: Found alac atom (36)!

I would just like a plain MPEG or AVI format, 320x240. My (mostly uneducated) guess is that there's a lot of crap left in the stream by the Avid software that he's using and this is causing problems for either mplayer or Quicktime. One method would be to strip all the video down to some appropriately raw format and re-encode it to some clean, open format. Unfortunately, this is beyond my range of expertise, I'm a musician, not a video editor... Any help would be appreciated.
