ffmpeg- configure libamrnb not found, could not transform mpg2/mp4
by javaone9＠yahoo.com 24 Dec '08

24 Dec '08

Hello, We need to transform various video formats to flv video for web. After I install vlc player(which has many?audio/video libs)?on Fedora Core 10, then I downloaded ffmpeg. ? then run configure in ffmpeg directory: ? ./configure --prefix=/usr/local --enable-gpl --enable-shared --enable-libamr-nb --enable-libamr-wb --enable-libmp3lame --enable-libvorbis --enable-libxvid?? --enable-libx264 --enable-pthreads --enable-nonfree --disable-ffserver --disable-ffplay ? ERROR: libamrnb not found If you think configure made a mistake, make sure you are using the latest version from SVN.? If the latest version fails, report the problem to the ffmpeg-user at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.err" produced by configure as this will help solving the problem. ? I googled web, but could not find the libamrnb(wb) that for audio for mobile device. If I run ./configure without options, ffmpeg will not transform mpeg2 video (from sony camcorder), mp4 (from cell phone) to flv. ? Thanks for any help. Dave

"alac: expected 36 extradata bytes"
by stepheneliotdewey＠gmail.com 24 Dec '08

Can anybody help me figure out what this error message means? When converting a MOV file with unknown audio encoding to an MP4/H264 file with AAC encoding, I get the following message over and over. Also, the resulting file has a play time of over an hour, when the original file is only 5 minutes long: [alac @ 0xcc1c70]alac: expected 36 extradata bytes44 bitrate= 11.3kbits/s [alac @ 0xcc1c70]alac: expected 36 extradata bytes The command I am using is: ffmpeg -y -i [original filename] -v 1 -threads 10 -vcodec libx264 -deinterlace -flags +loop -coder ac -refs 5 -loop 1 -deblockalpha 0 -deblockbeta 0 -parti4x4 1 -partp8x8 1 -subq 6 -me_range 21 -chroma 1 -slice 2 -bf 3 -b_strategy 1 -level 30 -g 300 -keyint_min 30 -sc_threshold 40 -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.7 -qmax 28 -qdiff 4 -i_qfactor 0.71428572 -cmp 1 -s [new_width]x[new_height] -acodec libfaac -ab 192k -ar 48000 -ac 2 -f mp4 [new filename] Also, incidentally, if anybody knows of a good resource for learning about some of these switches, I'd appreciate it. I inherited this command from other programmers, and I cannot find all of the switches in the ffmpeg documentation, so it's hard for me to predict the expected behavior. Thanks folks! Stephen

edit list not starting at 0, a/v desync might occur, patch welcome

Hi, The current SVN throws an "edit list not starting at 0, a/v desync might occur, patch welcome" message for that video: http://www.doppelbauer.name/desync.mov The strange thing, VLC media player (based on libavformat/libavcodec) plays this video without problems, but transcoding the video results in a bad audio-video desync. Output below ("ffmpeg -i filename").

Polo > I have wanted to make a single binary of ffmpeg with all the libraries built in it, but I could never figure out how to do it. I did figure out another way to make ffmpeg more portable in binary form on Mac OS X. What I did is copy libMP3lame.dylib and libfaac.dylib, then place them in the same folder as ffmpeg. Then set the variable DYLD_LIBRARY_PATH to the folder where these three files were kept. This variable tells the dynamic linker where to first search for library files. This is what I suggest you do. 1) Use the otool command to find out what libraries your copy of ffmpeg needs. (ex. otool -L ffmpeg) 2) Use the terminal to copy these library files to a folder where ffmpeg is kept. 3) Make a script that changes the DYLD_LIBRARY_PATH variable to equal the path where ffmpeg and its libraries are kept. 4) Make the script executable. Every time you need to convert a file just execute the script, then send ffmpeg the commands it needs. If you don't know how to make executable scripts this web page should help: http://www.dreamsyssoft.com/unix-shell-scripting/intro-tutorial.php Hope this helps.

FFMPEG hooks
by reshmagude2003＠yahoo.co.in 23 Dec '08

23 Dec '08

Hello, I need to enable hooks while I compile ffmpeg in order to be able to add a watermark to a file. Do hooks get enabled by default when i build ffmpeg? Looking at the configure file in the latest svn version makes me think they do. Or Do i need to specifically set an option like --enable-vhook? Thanks in advance.

Building Standalone FFmpeg on OS X and Debian Hi, first of all, thanks a lot for the help. I want to make a standalone binary to use it on OS X and Debian, I follow this guide (http://code.google.com/p/vs4p/wiki/BackEndApps) and works great, but I want to make a single FFmpeg binary with all the libraries inside like the Win32 binary I found here: ( http://sourceforge.net/project/showfiles.php?group_id=205275&package_id=248… ) The main reason for this is because I want to upload it to a shared hosting where I can't have SSH access. I have two different hostings, one in OSX and one in Debian, I already try the FFmpegX binary but it requires different commands and doesn't have FLV support. So If you cold give me a URL to a bulletproof guide I will appreciate it. Again? Thanks a lot for your help. -- Rodrigo J. Polo

watch HDV while I capture and while I'm not capturing
by jayson.rahmlow＠gmail.com 21 Dec '08

21 Dec '08

Hi All, I want to use my laptop as a video monitor for my HDV camcorder, HV20. I read somewhere that you can pipe dvgrab while capturing DV to ffplay and watch it. But I haven't figured out how to do this with HDV. Also, it'd be nice to see the video without capturing it, so I can frame my shots. Does anyone know how I would go about doing this? I tried this: sudo dvgrab -f hdv -showstatus|ffplay -f HDV the capture works but ffplay says "unkown input format". I also tried m2t mst and hdv with the same results. thanks, jayson www.oldchildprojects.com -- www.oldchildprojects.com
