Hi there, since dyas i am trying to figure out, what the right cmdline options are, i searched the web, tried various settings, but with no success... I used mencoder to render avis - but since i use vlc and thus ffmpeg, there has to be a solution. my previous mencoder setting - still working but with 1 audio track: audio: 'mencoder "'.$PARSEFILE.'" -ovc frameno -o frameno.avi -oac mp3lame -lameopts br=128:cbr:mode=3 -af resample=48000:0:2 -srate 48000'; 1 pass: 'mencoder "'.$PARSEFILE.'" -oac copy -vf pp=lb -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:autoaspect:vbitrate=1000:vpass=1:threads=2 -o "'.$out 2 pass mencoder "'.$PARSEFILE.'" -oac copy -vf pp=lb -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:autoaspect:vbitrate=1000:vpass=2:threads=2 -o "'.$out works plus qaulity is for tv okay.... can anybody help me translate that into ffmpeg lingo? i am using linux and only linux.... my first start was : 1 pass: "ffmpeg -v 2 -y -i $PARSEFILE -b 1200k -bt 4000k -vcodec mpeg4 -pass 1 -an $WRITEFILE.avi"; 2 pass "ffmpeg -v 2 -y -i $PARSEFILE -b 1200k -bt 4000k -vcodec mpeg4 -pass 2 -acodec libmp3lame -ac 2 -ar 48000 -ab 128k $WRITEFILE.avi"; but that didnt work - filsizewise I dont want to do h264 encoding. That works but a) is slow as grandma (which is nothing bad) b) filesize is not satisfying c) decoding cost cpu and doesnt work with vlc (dont ask here - ista fact).. so does anybody have a suitable 2 pass ffmpeg string? Thanks in advance NJ

fixing huge audio-delay

Hi, I'm having trouble with a video: The sound comes to early, roughly 120 seconds, which I can't adjust in mplayer since it only allows 100 seconds difference between audio and video. So I tried fixing with ffmpeg, but I failed. I have tried -itsoffset and -ss, but to no avail. What's wrong? Below is one of my several attemts.

FFMPEG question
by eowen＠wkag.com 06 Apr '10

06 Apr '10

I'm a fairly new user to this program, and have a problem that I can't seem to solve involving converting an animated AVI file into an MPEG using FFMPEG 0.5. I'm capturing weather radar images, then converting them into an AVI file which animates them. That process works perfectly and I end up with an AVI file that is approximately 105 megabytes every time. When I try to convert this AVI to MPEG using FFMPEG, I end up with a file that is only about six MB, has very poor resolution and obviously skips parts of the sequence. I've experimented with the batch commands for a couple of months and nothing seems to change this. The command I'm using is as follows: FFMPEG -i <input filename> -s 640x480 -r 25 -b 1200 -sameq -y <output filename> I've also experimented with a smaller bit rate but it makes no difference. As I said, this command sequence gives me a file about 5% the size of the original AVI and the quality is very bad. Any help would be appreciated. (And yes, I know that you can build an MPEG directly from the images, but i figured I'd better get THIS down before I talked the mysteries of "foo".)

footage converted to XDCAM422 (Mpeg2) becomes darker in quicktime

I read a few posts in the archives indicating that Quicktime applies some sort of magic gamma correction. Is this what's happening here? Is there anything I can do to tweak this on the command line? I observed two more things which might be worth noting: - if I convert to MJPEG and import into FCP or play in quicktime it doesn't look as dark. - if I export a PNG still frame from the original video it also looks much darker than the same frame played in ffplay Is there anything wrong with ffplay's display of the colors or ffmpeg's conversion? Shall I post this in roundup with sample files? Regards, Robert

Regarding Memory leaks

I have used ffmpeg's swscale library to resize the desktop captured image. I used the source for ffmpeg that is ffmpeg-checkout-snapshot.tar.bz2(6,303 KB) file. Are memory leaks possible by using above version of ffmpeg? Thanks

Right steps to avoid violation FFMPEG license
by t.katochin＠gmail.com 06 Apr '10

06 Apr '10

I also need the answer. This comment of Mr. Devid Kempers is not the official comment of the ffmpeg licenser. (right?) Therefore, I doubt that starting FFmpeg.exe might correspond to the following matters. > But if the semantics of the communication are intimate enough, exchanging complex internal data structures, that too could be a basis to consider the two parts as combined into a larger program.

Newbie needs help encoding stuff for iPod
by michaellud＠googlemail.com 05 Apr '10

05 Apr '10

Hi to all of you. First of all I want to tell that I am a newbie at video encoding stuff. So there are a lot of things I don't know of and don't be aware of. Please be so kind and respect that when answering just because everyone needs to get started somehow. I really would love to know good places of RTFMs for ffmpeg-encoding stuff, if you have some stuff/links to enjoy! ;-) So reading is not the problem at all, mostly it's just about understanding the stuff... ;-) For now I tried to encode some videos in HD what most of the time worked out quite fine. Now that our kids got two ipods nano (5th gen) from us, I thought it might be useful to give them some sort of videos like the moonbear (in germany it's "The Mondb?r") and stuff like that. So I could convert a sample video extraction with XMedia recode (newest version) which plays nicely on the ipods. But as I don't want to do stuff with windows, I would love to do this encoding for the ipods with ffmpeg. In the meantime I compiled ffmpeg on my own Ubuntu 9.10 virtual machine. This is what I tried and what doesn't work at all and I have absolutely no clue why. Maybe you can help me?? --------------------------------------- root at nw-vmw-dec:/DATALINK/mediathek1/VideoDB-TRANSCODING4/Der-Mondbaer# ffmpeg -y -i Der-Mondbaer-02-Schatzgraeber.avi -f mp4 -acodec libfaac -ab 160k -ac 2 -aspect 16:9 -s 640x480 -vcodec libx264 -vpre ipod640 -b 1350k -bt 1350k -r 30.0 Der-Mondbaer-02-Schatzgraeber.mp4 FFmpeg version SVN-r21822, Copyright (c) 2000-2010 Fabrice Bellard, et al. built on Feb 14 2010 19:14:56 with gcc 4.4.1 configuration: --disable-ffplay --disable-ffserver --disable-network --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-avfilter --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-libfaac --enable-libfaad --enable-pthreads libavutil 50. 9. 0 / 50. 9. 0 libavcodec 52.54. 0 / 52.54. 0 libavformat 52.52. 0 / 52.52. 0 libavdevice 52. 2. 0 / 52. 2. 0 libavfilter 1.17. 0 / 1.17. 0 libswscale 0.10. 0 / 0.10. 0 libpostproc 51. 2. 0 / 51. 2. 0 Input #0, avi, from 'Der-Mondbaer-02-Schatzgraeber.avi': Duration: 00:12:12.00, start: 0.000000, bitrate: 1209 kb/s Stream #0.0: Video: mpeg4, yuv420p, 640x352 [PAR 1:1 DAR 20:11], 25 tbr, 25 tbn, 25 tbc Stream #0.1: Audio: mp3, 48000 Hz, 2 channels, s16, 32 kb/s [libx264 @ 0x20a8600]broken ffmpeg default settings detected [libx264 @ 0x20a8600]use an encoding preset (vpre) Output #0, mp4, to 'Der-Mondbaer-02-Schatzgraeber.mp4': Stream #0.0: Video: libx264, yuv420p, 640x480 [PAR 4:3 DAR 16:9], q=2-31, 1350 kb/s, 90k tbn, 30 tbc Stream #0.1: Audio: aac, 48000 Hz, 2 channels, s16, 160 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height root at nw-vmw-dec:/DATALINK/mediathek1/VideoDB-TRANSCODING4/Der-Mondbaer# --------------------------------------- Warm regards from germany, Michael
