Greetz from Munich Sebastian </pre> Sebastian 2012-05-12T18:27:53 http://comments.gmane.org/gmane.comp.video.mencoder.user/12909 <pre>No problem, this is a note of appreciation.  I've just completed my first encode driven by "goddammit, this time I am going to get it right!", and the result is fantastic. The avi is visually superior to the ISO it was encoded from, more detailed, and I've compared them frame by frame.  True, I can bring out that detail in the ISO too by fiddling with the brightness and contrast in mplayer, but with the avi I don't need to.  What an excellent app, can't thank you guys enough.

The audio gradually going out of sync with the video. I'm only having this problem with M4V files. I'm using the following mencoder command: "input.mp4" -of lavf -lavfopts format=asf -vf harddup -ovc lavc -oac lavc -lavcopts acodec=wmav2:vcodec=wmv2:autoaspect:keyint=25:vqscale=2:vqmin=2:aglobal=1:vg lobal=1 -mc 0 -ofps 25 -o "output.wmv" While transcoding, I get the following warning several times: [wmv2 &lt; at &gt; 012521a0]warning, clipping 1 dct coefficients to -255..255 The properties of input.mp4: &gt; General Format : MPEG-4 Codec ID : M4V File size : 415 MiB Duration : 53mn 15s Overall bit rate : 1 090 Kbps Encoded date : UTC 2012-05-03 22:06:07 Tagged date : UTC 2012-05-03 22:58:38 &gt; Video ID </pre> Wietze 2012-05-05T11:40:23 http://comments.gmane.org/gmane.comp.video.mencoder.user/12907 <pre>I used my typical pullup routine on a 60 fps interlaced video that resulted in lots of duplicate frames, so I suspected faulty telecining for the source. Next I tried feeding it to ffmpeg specifying -r 29.97 and -deinterlace. I expected to see duplicates of every 5th frame, but what I found was a pattern of thirteen with duplicates at 5, 10, and 13. Does that identify the original frame rate of the source video? Normally the sources I capture are originally 24 fps, what could the original frame rate of this source be? Thanks. Laine Lee </pre> L. Lee 2012-05-05T03:51:43 http://comments.gmane.org/gmane.comp.video.mencoder.user/12903 <pre>How important are B-frames and does a video really need them? "MEncoder's libavformat muxing is presently broken and can generate INCORRECT files in the presence of B-frames. Moreover, due to bugs MPlayer will play these INCORRECT files as if nothing were wrong!" If I encode using -of lavf, the above is displayed. So, I would set bframes=0 thinking this must be the correct procedure. But I am now wondering if a video is suffering in quality due to zero B-frames in the video. Also, in MPEG-2 files, I notice they have - 99% of the time - BVOP. I think I remember it stands for bidirectional video object plane. Is this just another name for B-frames? </pre> Sylvester 4 2012-05-04T03:23:48 http://comments.gmane.org/gmane.comp.video.mencoder.user/12901 <pre>Hello everyone, I have 2 questions on MenCoder: 1) Is it possible to change filter parameters while something is going?

I've used mencoder for quite a while to encode h264 videos, and now I'm looking to test VP8. Unfortunately, I'm having trouble figuring out how to pass the libvpx-specific options over to ffmpeg to do the encoding. Here's a somewhat shortened version of command I'm working with: mencoder SC_0010B.VOB -o SC_0010B.vp8 -oac copy -ovc lavc -lavcopts threads=8:vcodec=libvpx:vbitrate=1000:subq=6:o=qmin=0,qmax=60,mb_threshold=0 -vf hqdn3d=2:1:2,harddup That seems to work fine as far as producing a VP8-encoded video (I'm not worried about the audio at this time). However, I also want to pass the following options, as documented in ffmpeg's man page under "libvpx encoder AVOptions:" cpu-used=0,auto-alt-ref=1,lag-in-frames=16,quality=good Unfortunately, I can't figure out how to make that work. If I add them to the o= argument, I get "Your options /&lt;SNIP&gt;/ look like gibberish to me pal". If I add them to -lavcopts directly, I get "Error parsing option on the command line: -lavcopts", I'm not sure h</pre> Jared 2012-04-08T16:26:25 http://comments.gmane.org/gmane.comp.video.mencoder.user/12890 <pre>I'm encoding directly from a DVD, and I would like to know how do I include a subtitle that is not hardcoded into the main movie.

Recently I updated and something broke. Of course, I didn't capture what version I was using before (if svn has that kind of history, I'd dig it out). Anyway, from researching the problem, it appears this may fall into the realm of ``This was never supported and if it worked at all it was by accident; consider yourself lucky that it worked that long.'' If so, then I won't bother trying to figure out when the error was introduced. In some hits I've seen, it looks like trying to use -oac copy with AC3 was unsupported, but I think those were posted prior to me having an actual working binary at some point. So, onto the error. I have a vob file ripped from a DVD. If I try to do something like: mencoder -quiet -endpos 00:03:00 -oac copy -ovc copy -o a.avi a.vob I get this: MEncoder SVN-r34790-4.6 (C) 2000-2012 MPlayer Team success: format: 0 data: 0x0 - 0x41bac000 libavformat version 54.2.100 (internal) MPEG-PS file format detected.

I am trying to convert Geovision AVI files (from a CCTV system) into MPEG4 or any other format that can be played without needing access to Geovision's software. I'm using Ubuntu 10.10 (x86, 32 bit) and MPlayer 1.0rc4-4.4.5 from the Maverick repositories. The Geovision files can be viewed with mplayer without any problems. But when I try to use mencoder to convert or copy out the video, I get "duplicate frame" errors as shown below in the sample attempt to extract a few seconds of video. An output file is created, but it is always 4108 bytes in size and contains no video. Two listings below - first, the errors from mencoder, and after that the output from mplayer when it successfully plays the Geovision file. Any suggestions on how to proceed?

These movies were found on removable media with dates in the spring of 1996. I think they were made on my PowerMac 7500/100, on those dates or not many years before. That would be with System 7.5.something. I think I made them using some standard recording software of such Macs. I think the video source was a S-VHS camcorder, connected to the Mac via a S-video cable; the audio came in through the Mac's microphone or an external microphone. In Mac filesystem terms, these movies have type/creator of MooV/ttxt. Each has a small resource fork, containing just one resource (of type MooV), and a large data fork. I have copied these files to modern systems, losing the resource fork along the way. I can play them with mplayer and QuickTime 7 on Windows Vista and MacOS 10.6 (also the current QuickTime on MacOS 10). Oddly, mplayer and QuickTime disagree about the frame rate.

However I'm responsible for a presentation of some animations, and every now and then I need to encode something. Recently I've received 6 minutes animation weighting 5GB, in 900x600 resolution, but the animation is quite static. What's funny, it does look good when played with Media Player Classic. Mplayer can play only two seconds, then stops. I need to make the file smaller. I managed to encode it to 76MB, but the problem is, I'm experiencing jittering during scene switch (fade-in, fade-out) and scrolling of whole view. Size is not that important (well, it can't be 1GB/s), but I really need smooth video. I'd rather like not to have compression artifacts.

The original frame rate is 15 frames/per second, and it takes 300 seconds to play the whole video. I want the video to play faster so that it takes less time to complete, so I change the frame rate using the following command: mencoder in.avi -o out.avi -ofps 100 -ovc copy However, out.avi still take around 300 seconds to complete, even though out.avi does have fps of 100fps according to the info displayed by mplayer. What command options should I use if I want the output video to be complete in 50 sec? Thanks.

The command that works so far is this: ffmpeg -y -i %in -threads 4 -deinterlace -f mpegts -r 25 -vcodec mpeg2video -s vga -aspect 16:9 -maxrate 1800k -b 1500k -qmin 3 -qmax 5 -buf\ size 4096k -mbd 2 -bf 2 -flags +4mv -trellis -aic -cmp 2 -subcmp 2 -g 300 -acodec libmp3lame -ar 48000 -ab 128k -ac 2 %out However since I would like to serve this from a Mediatomb UPnP instance, it needs to be transcoded with at least 25 FPS. On my 4 core 2.6 GHz server the transcoding happens with ~13 FPS. Is it possible to speed this up? Does mencoder have a better/faster alternative for the above line?
