[02:06] <piercedwater> Can someone help me figure out why ffmpeg isn't using full cpu? Here is my command: ffmpeg -threads 4 -vcodec h264 -i /media/spot/Halloween\ 2.mkv /media/spot/test.mp4 [02:08] <iive> shouldn't it be libx264 ? [02:08] <piercedwater> i shows libx264 in -codecs, but it is still slow when i use it [02:09] <piercedwater> actually [02:09] <piercedwater> it is listed on -encoders [02:09] <piercedwater> but is not found when i try it with -vcodec [02:10] <piercedwater> Unknown decoder 'libx264' [02:13] <JEEBsv> that's because you're setting it before the -i [02:13] <JEEBsv> before the -i = for decoding [02:13] <JEEBsv> after the -i = for encoding [02:14] <piercedwater> ffmpeg -threads 4 -i /media/spot/Halloween\ 2.mkv /media/spot/test.mp4 -vcodec libx264 [02:14] <piercedwater> still ~ 20 fps [02:14] <piercedwater> i get >100 with handbrakecli in linux [02:15] <piercedwater> hmm [02:15] <JEEBsv> set a preset? [02:15] <JEEBsv> preset sets the defaults that control speed VS compression [02:15] <JEEBsv> default is 'medium' [02:16] <JEEBsv> http://mewiki.project357.com/wiki/X264_Settings#preset [02:22] <piercedwater> Unrecognized option 'preset' [02:22] <piercedwater> workswith vpreset [02:22] <piercedwater> but still slow [02:25] <JEEBsv> then you have an old ffmpeg [02:25] <JEEBsv> and/or libx264 [02:27] <JEEBsv> anyways, go and check what handbrakecli is doing, check that your ffmpeg/libx264 isn't any older than that handbrakecli you have and try to match preset-wise, and maybe with some other settings :P [02:27] <JEEBsv> after all [02:27] <JEEBsv> handbrake on the background is using ffmpeg [02:27] <JEEBsv> and libx264 via it [02:27] <piercedwater> k [02:30] <piercedwater> ty [02:41] <CodeOfficer> I took a widescreen vid on my iphone4s that I want to shrink down a bit, when i run ffmpeg with these options its not keeping the aspect ratio. thoughts? [02:41] <CodeOfficer> ffmpeg -i IMG_0314.MOV -s 640x480 -aspect 16:9 IMG_0314-640x480-16-9.MOV [02:42] <CodeOfficer> oh, duh [02:42] <CodeOfficer> wow i need sleep [02:42] <CodeOfficer> pretend i wasnt here [03:12] <Shazzamy> I have a .TOD video file that came from a JVC Everio camcorder. I'm trying to find the best settings to use that will provide the best quality file conversion. Mac OS X 10.6.8, ffmpegX (ffmpegX v0.0.9y Jan 26, 2008) [05:18] <beastwick987> Could anyone assist me? I installed FFMPEG from the debian multimedia repositories, but it appears it cannot find my libx264 parameter (even though this version is compiled with x264 support). I have libx264-dev installed. I am running Debian SID. I have read a lot of documentation, at this point I am lost. [06:09] <shevy> Hmm. When I have an .avi file, I want to add an audio track to it [06:09] <shevy> that audio track is from a foo.mp3 file [06:15] <shevy> how can I list all available options to -vcodec [06:19] <composite> anyone know how to change the speed of an mp4 and make a new file? [06:37] <Kuukunen> shevy: -codecs [06:42] <shevy> thanks Kuukunen works nicely [12:14] <rgl> is tehre a way to pipe multiple images into stdin and have a webm video file on the output? [12:14] <Mavrik> hmm [12:14] <Mavrik> not likely [12:14] <Mavrik> maybe you should try "mjpeg" as input... but I doubt it's possible [12:15] <cbreak> if ffmpeg can't do it natively, mplayer can read image sequences and output it in a format ffmpeg can likely read [12:15] <cbreak> (mf://\*.png -vo yuv4mpeg ...) [12:16] <Mavrik> ffmpeg can read image files [12:16] <Mavrik> but not piped from something else [12:16] <cbreak> well, then you can use ffmpeg to convert it into something that can be piped :) [12:17] <Mavrik> I'm figuring he doesn't have files if he's asking that question ;) [12:17] <cbreak> depending on the format of the image data, it might be easy to just write yuv4mpeg output directly [12:18] <cbreak> in a program I worked on recently I use ffmpeg internally to pipe raw audio/video into a different process [12:18] <cbreak> works nicely [12:19] <cbreak> but it was a pain to get working nicely :) [12:21] <rgl> humm will look at yuv4mpeg [12:22] <cbreak> as the name says, it uses yuv and not rgb, not sure if there's a way to change that. [12:22] <cbreak> or the color subsampling [16:09] <hallowicked> Could somebody tell me is it possible to change the way the logfile prints or add TEXT to it [16:10] <Mavrik-> logfile? [16:10] <hallowicked> yes [16:10] <hallowicked> like normally it would print like [16:11] <hallowicked> frame=56265 fps= 49 q=30.0 size= 365582kB time=00:31:15.97 bitrate=1596.4kbits/s [16:11] <hallowicked> can i make that say text instead of just this [16:11] <Mavrik> huh [16:11] <Mavrik> as far as I know that's hardcoded [16:12] <hallowicked> ok like this [16:12] <hallowicked> WWE.Vengeance.2006.DVDRip.x264 (res:576x432 crf:19.0 dur:35:00 fps:29.970 SIZE:445.83MB br:1490 Kbit/s) [16:12] <hallowicked> possible to make the log print like that [16:12] <Mavrik> no [16:12] <Mavrik> you'll have to pipe output to some script that can reformat it [16:12] <hallowicked> hmm could u point me into a direction to doing that [16:19] <hallowicked> Mavrik, got nething bud? [16:19] <Mavrik> well, that depends on your OS, you're knowledge of scripting or programming languages etc. [16:19] <hallowicked> windows is os [16:19] <hallowicked> and my knowlege is very small but if sent to the right track i can figure it out with google i think [16:20] <Mavrik> hmm [16:20] <Mavrik> hallowicked, you'll have to find out how to read stderr output of ffmpeg and reformat it [16:20] <Mavrik> don't know much about windows scripting/programming [16:20] <Mavrik> you can also use something like python/etc to start ffmpeg and grab it's output [16:20] <Mavrik> but... it's probably more work than it's worth [16:20] <hallowicked> right [16:21] <hallowicked> what about ina batch file if i put text will that change anything [16:21] <hallowicked> right now im exactly getting [16:21] <hallowicked> frame=85412 fps= 49 q=28.0 size= 552319kB time=00:47:28.51 bitrate=1588.4kbits/s [16:21] <hallowicked> which is great after a week of work to get that sent to my irc channel [16:21] <hallowicked> WWE.Vengeance.2006.DVDRip.x264 (res:576x432 crf:19.0 dur:35:00 fps:29.970 SIZE:445.83MB br:1490 Kbit/s) [16:21] <hallowicked> that is ideal [16:49] <omeone> Is anyone there? [16:52] <omeone> please( [17:05] <omeone> Nagy, are you alive? [17:09] <omeone> I understand. It's a Sunday morning in USA [17:19] <Nagy> I'm alive [17:22] <newl> whew [17:25] <omeone> ops... [17:26] <nadav> Hi [17:26] <omeone> I have problem: I use OpenCV to write videos... [17:26] <nadav> Any1 has experiance with Compiling bambuser ffmeg on an Android device [17:26] <nadav> ( using windows OS ) [17:27] <omeone> but when I try to write video to named pipe, I get another result [17:27] <newl> nadav: have you tried mingw (or cygwin) environment> [17:28] <nadav> yup, I am using cygdrive [17:28] <nadav> I mean cygwin [17:28] <nadav> I get "arm-linux-androideabi-gcc is unable to create an executable file" [17:29] <nadav> "C compiler test failed" [17:29] <newl> you probably need all the rest not just the gcc - install mingw it seems to be superior for this kind of thing [17:30] <omeone> I already posted my problem here: http://stackoverflow.com/q/8952997/1161481 [17:30] <omeone> As I know OpenCV uses ffmpeg to read/write videos, wright? [17:30] <nadav> using processmonitor I can C that there is no path mis-match, all env vars seem 2 B ok... ( as far as for the filesys hierarchy ) [17:31] <nadav> AFAIK, OpenCV is independent of ffmpeg, OpenCV is for machine vision kind of stuff while ffmpeg is more of a compression/streaming lib [17:32] <omeone> but OpenCV can't write videos without ffmpeg... [17:33] <nadav> correct, if U want to encode video ffmpeg isyour friend [17:34] <nadav> if U want machine vision, eg. text extraction, no need for ffmpeg, only OpenCV [17:34] <omeone> you haven't seen my link http://stackoverflow.com/q/8952997/1161481 [17:35] <newl> that opencv must really eat up cpu [17:36] <omeone> As I know, OpenCV uses ffmepg to write videos. When I'm trying to write video in a named pipe it getting corrupted (sorry for English) [17:37] <nadav> write the file to the disk and have apache read it from the disk [17:37] <nadav> R U using Linux ? [17:37] <omeone> yep [17:37] <omeone> I need an-fly upload [17:37] <omeone> *on fly [17:38] <nadav> I am more of the windows guy though I know it is possible with Apache [17:40] <omeone> Maybe, ffmpeg encodes video in a different way for named pipes??? [17:43] <omeone> Or ffmpeg rewrites some data which has been written (named pipes don't allow that) [17:44] <nadav> ffmpeg get a raw video image and encodes it to whatever format U want [17:45] <omeone> OpenCV only allows me to select a codec... [17:46] <omeone> next interesting thing: in a "corrupted" video opened in hex-editor I can see this:"Lavf53.3.0" [20:18] <mape> Hi, is there any way of dumping a series of frames into images in multiple formats while making sure they have the same %d ? Ie making one thumb and one full size. [20:20] <Mavrik> mape, try specifying several outputs [20:21] <mape> Mavrik: won't adding more -s overwrite the previous one? [20:21] <Mavrik> -s? [20:21] <Mavrik> -s seeks the input [20:22] <mape> -s sets the size? [20:22] <Mavrik> er, sorry [20:22] <Mavrik> saw -ss -_- [20:22] <Mavrik> mape, basically you have to do something like [20:23] <Mavrik> ffmpeg -i <input> -codec:v <whatever> -vf scale=320:240 output1.jpg -codec:v <whatever2> -vf scale=640:480 output2.jpg [20:23] <Mavrik> you need to repeat the whole encoding setup after the first output to define a second output [20:23] <mape> hmm k [20:23] <Mavrik> I'm not sure if it works with images though :) [20:25] <mape> it does seem to work as in it is outputting two files with different sizes but the % doesn't seem to match. [20:26] <mape> or that might just be me missing -r.. [20:26] <mape> Indeed it was, Mavrik thanks for your help :) [20:27] <Mavrik> ^^ np [20:47] <iiu7> Trying to convert from AAC2 to what would work, but I keep getting this error whether I'm trying AC3, MP3 or something else. http://pastebin.com/zcmA3nQE [20:47] <iiu7> What's the deal with that? [20:48] <Mavrik> usually the command line helps [20:49] <Mavrik> it seems timestamps on input (or output?) are wrong [20:51] <iiu7> ffmpeg -i foo.mkv -map 0:0 -vcodec copy -acodec ac3 bar.mkv [20:53] <iiu7> I get the same error if I use -acodec copy [20:53] <Mavrik> hmm, that shouldn't happen really [20:54] <Mavrik> which ffmpeg version? [20:54] <iiu7> ffmpeg version git-2012-01-02-0af34c4 [20:55] <iiu7> I build it about a month ago. [20:56] <iiu7> The file I have has x264 as video, but then it has 2 audio streams 1 is ac3 and 2 is aac2, I just need to remove the second audio stream hence the "-acodec copy" for -map 0:1. [20:56] <Mavrik> I suggest you try to find out which stream confuses the muxer and try to reencode it [20:57] <iiu7> How do I do that? [20:58] <iiu7> I get the "in stream 0: 83 >= 42" error, but does that even make sense? [20:59] <Mavrik> iiu7, try your command with -vn [21:00] <iiu7> Disabling the video with "-vn" works! [21:00] <Mavrik> hm [21:01] <Mavrik> if you try to reencode the video does it fix? [21:02] <iiu7> How do I do that? [21:06] <iiu7> If I use " ffmpeg -i foo.mkv -map 0:0 -vcodec libx264 -acodec ac3 bar.mkv" and just re-encode with x264, then it works, but I don't know if that's actually the same as "copy", or if it is then again compressing using x264. [21:26] <leuhmanu> hello [21:26] <leuhmanu> somebody for an strange ffmpeg -f image2 issue ? [21:30] <leuhmanu> I have make an ugly script to convert all motion capture in a video http://paste.pocoo.org/show/538909/ [21:30] <leuhmanu> It works but sometime I get : captures/Sunday-S04//h34-%05d.jpg: No such file or directory [21:31] <leuhmanu> It should be captures/Sunday-S04//h34-%05d.jpg: No such file or directory [21:31] <leuhmanu> oups [21:32] <leuhmanu> it should be ../../**h34-%05d.jpg [21:32] <leuhmanu> Any ideas ? [21:36] <leuhmanu> Or maybe there is an other way to do it ? [21:38] <relaxed> leuhmanu: the problem is your script and not ffmpeg [21:39] <leuhmanu> my script ? and you know why ? [21:40] <leuhmanu> date are ok in the tmp file [21:40] <leuhmanu> and it's ok if I comment ffmpeg and add an echo [21:42] <newl> leuhmanu: it is always the script [21:42] <leuhmanu> but where ? :( [21:43] <relaxed> leuhmanu: From looking at the script it appears you're new to bash scripting. Reading this should help: http://mywiki.wooledge.org/BashGuide [21:48] <newl> leuhmanu: what is the url to the pastebin [21:48] <leuhmanu> I had no external resource when I did that ... [21:48] <leuhmanu> http://paste.pocoo.org/show/538909/ [21:49] <leuhmanu> but thanks I will look again the basic [21:50] <newl> you don't need to save the results of the grep of the one file to a tmp file and ... [21:51] <leuhmanu> yes indeed, but witout google :) [21:51] <newl> maybe say what you want to do - that script was obviously made without any external input ;) [21:51] <leuhmanu> in fact I have lot a picture in a folder [21:54] <leuhmanu> like 13h27-00001.jpg ... 13h27-00010.jpg 15h23-00001.jpg ... 15h23-00010.jpg etc [21:54] <leuhmanu> and I wanted to make a video of each **h** [21:55] <leuhmanu> and one of all the picture [22:06] <newl> lc=`ls *-00001.jpg` [22:06] <newl> echo $lc [22:09] <newl> use basename to get the $b [22:09] <newl> ffmpeg -y -r 15 -f image2 -i $lc $b.avi [22:11] <newl> you 'done < .... ' is a heredoc and is <<< not just < btw [22:16] <leuhmanu> mhhh [22:16] <leuhmanu> thanks I will look :) [22:16] <mape> Is there any way of getting ffmpeg to produces as high quality gif animations as 'convert'? Seems pix_fmt rgb24 makes them look horrid [22:19] <newl> leuhmanu: looks like you want all the *-00001.jpg in one 1.avi? ...... *-00010.jpg 10.avi ?? [22:19] <relaxed> mape: I don't think so. [22:19] <mape> Ok [22:20] <mape> Too bad, convert does a good job but takes forever [22:21] <leuhmanu> newl: no, all .jpg in one .avi and for each xx.xx another one [22:21] <leuhmanu> but I have found a way with mencoder for the first part [22:25] <newl> in your script you are only grepping for 00001.jpg [22:25] <leuhmanu> yes and then is use the %05d [22:25] <newl> if you want . pastebin the ls of the files you want in each avi - i'm kinda confused [22:27] <newl> i think i get what you want get each xxhxx and then make avi of each [22:28] <newl> each xxhxx can be 00001 -> 000010 [22:31] <newl> more for ya for i in *-00001.jpg; do [22:31] <newl> that will get the xxhxx so you won't need the tmpfile [22:33] <leuhmanu> hum now it's work [22:33] <leuhmanu> with the same script as before but with change [22:34] <leuhmanu> http://paste.pocoo.org/show/538955/ [22:34] <newl> <<< :) [22:34] <leuhmanu> nop :) [22:34] <leuhmanu> anymay thank a lot [22:35] <leuhmanu> but yes indeed I remember now the <<< versus < :/ [22:36] <leuhmanu> have a nice night/day, bye [22:47] <b_jonas> Can you help me figure out how to use -map or something? I have five input files, and I want to concatenate one audio track from each like 0.1,1.1,2.1,3.2,4.1 to a single audio file. All five input files have two audio tracks. [22:48] <b_jonas> I can't figure out how to make ffmpeg encode more than one track. [00:00] --- Mon Jan 23 2012
