What is a good format for a video on the Internet?

Sunday, September 27th, 2009

I have a fairly large collection of videos that I be shot, should be made available over the Internet. Do we want to minimize the consumption of bandwidth, but at the same time I offer good quality. I am good with the video size 320×240, but would rather not be smaller than the walk. I do not know how Flash video codec, and prefer something more standard in the industry, such as MPEG4. Ffmpeg I am looking for very specific information about the Bitrate, Video and audio codec, container, etc. I have Linux available, so I can use mencoder, so I'm looking for good quality, especially for the transfer (not live), so I order special options for the convergence of video and audio coding sequences, etc. What is the best combination of quality, file size usage and availability (ie, all users can watch the video?) ? Delivery method is not so important, I can only give the video link, or I need a Flash Player.

Iphone – Converter MOV format movies

The goal is simple: with a copy of a movie from the local disk, the size, you fit on the iPhone display and implement appropriate codes to give you a good picture and sound quality. But first I want to stress that due to the size of the film to focus on the optimization of the compression itself. Write a script for this operation is useless – it is a line in the console: ffmpeg-i INPUT _File. Avi "-f mp4-vcodec mpeg4-maxrate 10000-b 7000-R 29th 97-qmin 2-qmax 5-bufsize 4096-g 300-acodec aac-ab 128k-s 480×320-aspect 4:3 "output_file. MOV "Of course you do not have the appropriate codecs (if already installed), and input file (done the movie) to.
# Apt-get install ffmpeg libfaac0 FAAC mpeglib libmpeg2-4
After a long process, and consumed enough, we get an output file. Then install the iPhone / iPod Touch with gtkpod, for example. Voila!
Synchronization of the agenda.
At this point, the procedure is more complicated. You must use the application's installation MNPlight Repository: http://movenplay. gforge. INRIA. fr / iphone. Application roles are described in the homepage of the project, I firmly believe that you should have no trouble understanding it. The application allows MNPlight Import and Export of phonebook format in Mozilla Thunderbird (Gmail), and the export / import format calendar in Google Calendar. It also has some other features that I personally have never used. I recommend visiting the website for more information.
Your MP3 ringtones for iPhone
Warning! This process only works with the iPhone with 1 1. 1 software. iPhone uses the AAC-encoded audio. Most of us have files to *. mp3, or *. OGG. The conversion itself is a complicated. First, to convert an audio file in *. WAV format with mplayer, which in turn next to the *. wav by the respective encoder (FAAC), which creates a performance M4A file. I wrote the script that automates the process described above:
# Bin / bash # night Sebastian 'http://night Auczak #. Corridor. pl # Convert mp3 ringtone on the iPhone
echo Enter the name of the mp3 file (without extension) "echo-n"> "IN OUT read =" `ls | grep $ IN. mp3 "" echo "convert MP3 to WAV: mplayer-vo null-vc null-ao pcm: fast: file = $ IN. FAAC out $ wav-b 128-c 44100-W $ IN. RM WAV $ IN. wav
You need the output file from *. will rename m4a to *. m4r and then add a space at the end before the file Extended, E. g.
Tone $ ls. $ Mv M4A audio. "m4a audio. m4r "Ringtone $ ls. m4r Now, let's iPhone 1st Download the corrected file MECA 2nd Install the corrected file in: / System / Library / Frameworks / Mecca. Framework / 3 M4r install the file in the directory / Library / Ringtones / 4 Restart the phone
The tone should be in the phone menu available.
OpenSource tools, as we see, can use iPhone, regardless of iTunes and Apple products.

How do I convert AVI files to DVD-Video format (VOB) with mencoder?

Friday, September 25th, 2009

I am new to Ubuntu Linux, which I have and mencoder too, and have synaptic version of MPlayer and MEncoder. When I write: mencoder-ovc help, then output these codecs will be available:
  copy – frame copy, without re-encoding. Does not work with filters.
  – Frameno special audio-only file of 3-pass encoding, see DOCS.
  RAW uncompressed video -. Use fourcc option to set format explicitly.
  nuv – Nuppel
  lavc – libavcodec codecs – best quality!
  vfw – VfW DLLs, read DOCS / en / encoding of the guide. html.
  qtvideo – QuickTime DLLs, currently only SVQ1 / 3 support.
  libdv – DV encoding with libdv v0. 9. 5
  xvid – XviD
  x264 – H. 264, encoding
Suggestions on how I look at things in a normal video player?
