When using libmp3lame with ffmpeg is there a way to use lame options?
Code:
ffmpeg -i foo -acodec libmp3lame foo.mp3
For example:- --vbr-new, --abr <bitrate>, -V (n) and -q <arg>
I think it is possible to pipe ffmpeg to lame then use the options.But is it possible to do it without a pipe.
Code:
ffmpeg -i foo -f wav - | lame --vbr-new -V 4 - foo.mp3
Is there a difference in quality between converting an audio file (e.g. *.wav) to MP3 using LAME or FFMPEG? Or do they produce the same results?

I use Kino to transfer dv from my camera and also use it for video editing, but there are very few GUI options when it comes to transcoding the edited files into, say, h264. Kino is using ffmpeg, and I know there are a plethora of options. For instance, here is the output of the logfile from a file I made with h264 and the best quality available in Kino.#options: 768x576 fps=25/1 cabac=0 ref=1 deblock=0:0:0 analyse=0x1:0 me=dia subme=8 psy_rd=1.0:0.0 mixed_ref=0 me_range=4 chroma_me=0 trellis=0 8x8dct=0 cqm=0 deadzone=21,11 chroma_qp_offset=-2 threads=2 nr=0 decimate=1 mbaff=0 bframes=0 keyint=300 keyint_min=25 scenecut=0(pre) rc=abr bitrate=2048 ratetol=2.0 qcomp=0.50 qpmin=2 qpmax=31 qpstep=3 ip_ratio=1.25 aq=1:1.00Frankly, I am not that impressed with the result, and would like to use settings that give a better result, e.g. adjusting bitrate and more passes
View 1 Replies View RelatedI'm writing a wrapper for FFMPEG and need help of a multimedia guru. The more I read about containers, formats and codecs the more confused I become, it all seems to be a pretty big mess. To convert a video file with ffmpeg you need to specify a few arguments for ffmpeg:
- input file
- some video/audio options (bit rates, sizes and so on)
- format (to force format)
- codec (to force codec)
- output file
My confusion is all about the format and output file extension. If I want to encode my file in MPEG-4, I'll use either 'libx264' or 'libxvid' codec. Then the encoded stream needs to be stored in a file. If I use '.mp4' as the output file, it'll be stored in that file. If I use '.mkv', the video will still be MPEG-4 but stored in a Matroska container. But what do I do with the format option? When I force the format to 'mp4', does it mean I don't have to enter output file, it'll be stored as '.mp4' anyway? Or if I use '-matroska' will I still have to put it into a container '.mkv'? Can I use a '-matroska' format but '.mp4' output file for example?
What's the difference between the format and output file in this context? Or what does forcing the format really do?
I bought un-managed VPS server for host a video sharing script. Server details

And that video sharing script needs "FFmpeg,Flvtool2,Libogg + Libvorbis,LAME MP3 Encoder" I searched google,forums,Articles. But i couldn't be able to find a way to install them on Centos
Ok, so I find myself ripping audio CDs frequently, which I then lame to mp3's to put on my media player. I usually define the --ta and --tl (artist and album) ID3 tags and batch encode each album, but don't bother with the track tags as I'd have to do each one seperately.
So, I'm working on a script to do all this for me, extracting info from 'pwd' etc. to fill in the blanks for --ta, --tl and --tt (track name). All is working well, except that I can't get sed to pass on the "" character to lame to escape spaces.
Here's what I've got so far: (trouble spot is bolded - no need to pay attention to the rest of it)
Code:
All this does is pass a 'space' on to lame, which it takes as an invalid argument.

A few days ago I setup a new slice, and now I want to use it to convert ULAW (μ-law) WAV files into MP3's.
If I would only install LAME this would give me an 'Unsupported data format: 0x0007'. Because LAME doesn't support ulaw encoded wav's only Linear PCM's.
I have read that one can use the Libsndfile and use it with LAME --fileio=libsndfile (or something like that) when 'MAKE'-ing Lame. In this case because of the additional encoding library sndfile Lame can read and encode the ulaw into mp3.
I have also read another solution is to first convert the ulaw-wav into a pcm-wav with sox, and afterwards convert the output into an mp3 with lame. This seems to be a lot of extra system resources.
I am looking for a hands on tutorial howto wget, compile, install and run LAME with Libsndfile on Ubuntu Lucid (commandline only) so I can encode incoming ulaw files into mp3's?

I've got a bunch of HD files in .mkv format that I want to convert to a format that the 360 will read (currently just trying .avi files) so I can stream the media to my xbox360. I'd rather avoid transcoding the entire file, so I tried unpacking the .mkv file into audio and video (and subtitle if necessary) and repacking said file into avi using ffmpeg. The repacking is where I am having the problem. Here's the commands I tried at first (it might look familiar):
Code:
mkvextract tracks file.mkv 1:temp_video.avi 2:temp_audio.ogg 3:temp_sub.srt
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy file.avi
However, I keep getting this annoying error:
Code:
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height Where stream #0.1 is the output audio stream to the .avi file. I think I have narrowed it down to the fact that the input streams are all 6 channel (5.1 surround sound) which mp2 doesn't support (the ffmpeg audio default) so I did this instead:
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame file.avi
I'm still getting the same error, but when I use
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame -ac 2 file.avi
to change the sound to stereo it works. Problem is I'd like to keep my media in surround sound. Any thoughts on how to get all 6 channels in the new mp3 file? I'm fairly certain that mp3s support 5.1. And after some messing around, I haven't found that my ffmpeg can transcode audio format from 5.1 back to 5.1. So since (I think) the 360 can play .ac3 files I decided to just copy both the video and audio file to the .avi file sans transcoding using
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec copy file.avi
however now about halfway through, I run into this error:
Code:

av_interleaved_write_frame(): Error while opening file I can't seem to find any solution to this problem anywhere online, does anyone know how to get around this?

It seems more and more people are encoding with the MKV container on bit torrent these days, and a lot of the shows I'm watching are starting to release almost exclusively with .mkv formatted videos. This is not a problem if I want to watch the shows on my computer but I've become accustomed to watching them on my PlayStation3 using my thumb drive. It seems the offical documentation for the PS3 includes a list of supported codecs [URL], but when I use FFMPEG to convert with libxvid video and aac audio in the MP4 container my PS3 says the output video is not supported. I've also tried most combinations of libxvid, libx264, mpeg4 for -vcodec and aac, libmp3lame for -acodec in several different container formats but nothing seems to work. I have found one option that always works:
Code:
ffmpeg -i inputfile.mkv -sameq -ac 2 outputfile.mpeg
I don't like doing it this way, however, as the output file is twice the size and the audio quality is terrible. If I don't reduce the audio channels to only two using -ac 2 FFMPEG throws an error (apparently MKV audio supports 6 channels). And preserving the video quality in MPEG video using -sameq produces too a large file (and I prefer to keep my files as lossless as possible). Ideally I want to save the files on an external HD I have but if a single episode of a show is 1.5 GB it's not very pratical.
Anyway, the PS3 docs say it supports h264 and xvid with aac audio, but apparently I'm doing something wrong. Has anyone sucessfully used FFMPEG to convert an MKV to MP4 for use on a PS3?
I have a .mkv container with proper video (h264/~6000kbps) and audio (DTS/1500kbps). For some reason I want to have similar quality but with another video and audio codecs. For video it goes well and ffmpeg is very helpful here, no problems. Also, I want DTS to become AC3/320-448kbps/5-6 channels. Commands like this:
Quote:
ffmpeg -i in.dts/mkv -acodec ac3 -ac 5 -ab 448k out.ac3
gives me not proper reordered sound in channels, so I hear center on the right, music on the left, etc.
Is there a way to make that properly with ffmpeg?
Also, I have a question about multi core encoding cause I have a quad processor. Ffmpeg seems not using them in all the way, I get something like 25% of CPU usage while encoding. Command -threads, even using the h264, does not make any extra load of cpu.
I'm making little animated bits in GIMP with the gap package. I can only get GIMP to encode the files as .avi. Problem here is that when I try to use any converter, it compresses 80MB files down to 1MB-4MB files and, unsurprisingly, the video quality is terrible. WinFF and ffmpeg (via terminal) output at a drastically reduced size. Is there some way to keep the files big/big-ish? I don't want to lose any detail.

View 2 Replies View RelatedI installed Audacity to convert an mp4 to an mp3. Now, I don't necessarily need Audacity to do this, but for the time being I'm more concerned with getting Audacity to work properly as opposed to getting an mp3 onto my iPod.
In Audacity, I went to Edit>Preferences>Libraries. For the MP3 Export Library, Audacity recognizes LAME, but under the FFmpeg Import/Export Library it says "FFmpeg library not found." I hit the Download button and read this page on how to install FFmpeg, noticing the warning about needing FFmpeg 0.5 or later on Linux.
I fired up Synaptic and searched for "ffmpeg," chose the vanilla version and installed it along with two dependencies which I don't exactly remember but I bet they were libavformat52 and libavdevice52.
Back in the Audacity Preferences window I chose the "Locate..." button to point to the newly installed libraries, but Audacity is not recognizing/installing them successfully. I've tried pointing to the following files:
/usr/lib/libavformat.so.52
/usr/lib/libavformat.so.52.36.0
/usr/lib/i686/cmov/libavformat.so.52

I have inserted all the filenames individually into the script but when I ran it I got too many errors and i was wondering if someone knew a quicker way to do it e.g. a script that would batch convert all .flv files in that folder to .mp3 format.
how can i merge two files with ffmpeg?
one is : /home/pt/t/pa1.flv
