Hi, I wanted to combine 12 flash video files (from youtube) into a single avi file. So I did cat at Zachar*.flv > Zach_all.flv $ mencoder Zach_all.flv -o Zach_all.avi -forceidx -ovc copy -oac pcm The output shows skipping frames, and missing aspect information, as you see below. What do I need to do to fix that, so thet when I am transcoding into .avi, I do not get these skips and missing aspect info?

Help with MPG video encoding
by Walter Belhaven 20 Apr '13

20 Apr '13

Hi, I've got a question on how to get the best possible MPG encoding of a movie source, "at any price" so to speak -- i.e., as many bits as the encoder needs to get the highest possible video quality. It appears to me that the MPG encoding process is introducing artifacts that are present regardless of the amount of "free reign" I give to the encoder with respect to quantization, bitrate, and the like. My bottom line question is thus: "Are these artifacts inherent in MPG encoding, or am I just not twiddling the knobs and dials on the encoder correctly?" Here's all the details ... My source is a mixed hard- and soft-telecined "movie" at 1080/60i that I'm trying to tanscode to 480/24p, soft telecined to 480/60i, for ultimate burning to an NTSC DVD-Video. When I use mencoder to inverse telecine, crop out the crud, expand back to the original letterbox ratio (it's 2.35:1, not 16/9), and 'encode' the video with HUFFYUV (422P), the resulting video looks stunning, with no 'blocking' artifacts to speak of. This, of course, is as expected. But when I encode the video in MPG2 or MPG4, even with vqscale=1 or vqscale=2, I see sometimes severe blocking in the resulting video. Is this because the chroma is being subsampled vertically and horizontally (4:2:0), or is it because 'vqscale' is (perhaps necessary but) not sufficient to get "maximum quality at any price" encoding?

Puzzle - Frame skipping and audio
by Joseph Eoff 08 Jun '11

08 Jun '11

Hi. I've found that mencoder works really well for digitizing the tapes from my analog video camera. With the cropping and deinterlacing mencoder does, the resulting clips look really good on the computer screen. I recently bought a new digitizer - the old one was ten years old and just gave up the ghost. The new digitizer connects via USB and has a built in sound card. I would rather connect all of my video camera cables to just the digitizer box instead of connectig the video the digitizer and the audio to my sound card, so I changed my normal configuration to use the new sound card instead of taking the default and using the sound card built into the computer. Recording with the sound card explicitly set causes frame skips - LOTS of frame skips, to the point that the resulting video is completely useless. At first I thought is was a problem with the new digitizer, but the same thing happens if I specify the sound card built into the computer. The normal capture looks like this: mencoder -tv driver=v4l2:width=720:height=576:input=2:outfmt=i420:norm=pal:immediatemode=0:forceaudio -oac mp3lame -lameopts cbr:br=128 -mc 0 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8000 -vf crop=700:542:12:16,pp=lb,harddup -o capture.avi tv:// That command uses the new video digitizer on /dev/video0 and the sound card built into the computer. mencoder -tv driver=v4l2:width=720:height=576:input=2:buffersize=256:outfmt=i420:norm=pal:immediatemode=0:forceaudio -oac mp3lame -lameopts cbr:br=128 -mc 0 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8000 -vf crop=700:542:12:16,pp=lb,harddup -o capture.avi tv:// This one explicitly sets the same audio source, but skips like mad and produces a completely unusable video: mencoder -tv driver=v4l2:width=720:height=576:input=2:buffersize=256:outfmt=i420:norm=pal:alsa:adevice=hw.0:immediatemode=0:forceaudio -oac mp3lame -lameopts cbr:br=128 -mc 0 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8000 -vf crop=700:542:12:16,pp=lb,harddup -o capture.avi tv:// Does anyone see what I'm doing wrong to make mencoder skip when explicitly setting the audio source?

audio issue,
by Sw＠g 28 May '11

Hi all, I am using mencoder to record a webcam for security reason and wanted to record audio also, the issue I have is that when adding the audio into the mix the ended video is really fast. it seems the audio is having some issue. Please see below for information the command used, and the output. Many thanks for your time and assistance, command: mencoder tv:// -tv driver=v4l2:width=800:height=600:fps=15:device=/dev/video0:forceaudio:adevice=/dev/audio1 -ovc x264 -oac mp3lame -lameopts abr:br=128 -o cam_`date +%F_%T`.avi terminal output: $ mencoder tv:// -tv driver=v4l2:width=800:height=600:fps=15:device=/dev/video0:forceaudio:adevice=/dev/audio1 -ovc x264 -oac mp3lame -lameopts abr:br=128 -o cam_`date +%F_%T`.avi MEncoder SVN-r33159-4.5.2 (C) 2000-2011 MPlayer Team 162 audio & 359 video codecs success: format: 9 data: 0x0 - 0x0 TV file format detected.

x264encopts is not an MEncoder option
by Ovidio Pirvu 23 May '11

23 May '11

Hello list I have just updated mencoder from the daily Mplayer / Mencoder Launchpad repository and now encoding is botched. The error message is "*-x264encopts is not an MEncoder option*". Seems like a compilation error. Has anyone else bumped in to this?

Something to try if you have a Roku XD/S, Hauppauge HD-PVR, Mac OS X, EyeTV 3.5, and either an iPad or an iPhone 4
by L. Lee 15 May '11

15 May '11

Most, but not all of the requirements are in the subject. Here are all. Hardware: Roku XD/S Hauppauge HD-PVR either an iPad (1 or 2, it has been tested only with iPad 1) or an iPhone 4 (These Apple devices aren't required, of course, but that compatibility is what the conversion targets) Software and other: Mac OS X Snow Leopard EyeTV 3.5 Netflix or Crackle MEncoder (of course) I think this only works if you set up the Hauppauge to capture from your Roku with RCA instead of S/PDIF (I can't use S/PDIF with my Roku, Hauppauge and EyeTV because there is a a problem with stuttering during capture, and nobody at EyeTV has been able to help yet). If you have all that, the steps are simple. 1. Capture something from the Roku using EyeTV such as an HD Netflix stream. 2. Use the export command in EyeTV to create a single native h.264 video file containing both sound and picture. 3. Drag the exported file onto the icon of the AppleScript application linked for download below. 4. Wait for the Terminal to open and finish the conversion. The converted file is created in the same folder as the dropped source file. 5. Transfer to the iPad or iPhone 4. http://rowdyspace.utsa.edu/users/mek985/Public/plex/720p_Roku_to_iPad.zip The output is 1280X720 Baseline level 3.1, 24 fps. There are a lot of prerequisites for building MEncoder in Snow Leopard with x264 support, but once they are met, my build configuration command is "./configure --cc=gcc-4.2 --disable-live".

Cojoin two videos into one.
by Ivan Sy, Jr. 12 May '11

12 May '11

Hi everyone, this is my first post and I hope there's a magic behind this. i have a script that uses pwcview to pipe the video output to mencoder. That worked for me just fine. However, I am getting another camera and i'll use the same script using the new camera as the video device also piping the output to mencoder. This results to two video files. There's no problem with that. But, Is there a way that I can combine both videos into one? What im hoping to achieve is not to append VideoB to VideoA, but to have both on one video. On the left side will be feed from CameraA and the right side is feed from CameraB and saved in one file. Its like a split screen video of some sort - and if feed from any of the camera is shut, then it will just have a black blank screen on its side. Thanks!

ac3 channel mapping
by Rolf Ernst 11 May '11

11 May '11

Googled and googled but couldn't find the info or syntax for the channel mapping: I have ac3 audio in my input file and just want to downsample the bitrate, essentially leave the channel mapping in place. First of all, mencoder is a bit confused and thinks it is 2 channel but mediainfo clearly says six channels. That aside, I let it guess the channel assignments but it clearly gets it wrong. Mediainfo says that this is my channel assignment: Front: L C R, Side: L R, LFE (of course, I do not know whether this is correct but generally pretty reliable). What do I have to specify for -channels? Or do I specify -pan? Anyhow, how do I get the channel assignment right? -- /re* *

Any suggestions? Thanx
