Convert with ffmpeg2theora context menu item

Here's a simple registry file that when imported will add a menu item to your right click menu. This makes it easy to simply right click on a video file and click "Convert with ffmpeg2theora". The file will be converted using the default ffmpeg2theora parameters and the resulting file will be in the same directory as the source.

The requirement is that you have ffmpeg2theora.exe (named exactly that) in your c:\ directory.

1. Download ffmpeg2theora
2. Rename it from ffmpeg2theora-0.25.exeto simply ffmpeg2theora.exe
3. Copy the file (ffmpeg2theora.exe) to your c:\ directory.
4. Download the zip below containing the registry file and double click on the registry file to add it to the right click menu.
5. Test it out on a sample video file.

Download here (Convert with ffmpeg2theora.zip)


The file simply contains
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\ffmpeg2theora]

[HKEY_CLASSES_ROOT\*\shell\ffmpeg2theora\command]
@="C:\\ffmpeg2theora.exe %1"


Also attached is a reg file that will remove the context menu.

Example commands are at the end of this post.


ffmpeg2theora 0.25+svn16605 - Xiph.Org libtheora 1.1 20090822 (Thusnelda)

Usage: ffmpeg2theora [options] input

General output options:
-o, --output alternative output filename
--no-skeleton disables ogg skeleton metadata output
-s, --starttime start encoding at this time (in sec.)
-e, --endtime end encoding at this time (in sec.)
-p, --preset encode file with preset.
Right now there is preview, pro and videobin. Run
'ffmpeg2theora -p info' for more informations

Video output options:
-v, --videoquality [0 to 10] encoding quality for video (default: 6)
use higher values for better quality
-V, --videobitrate encoding bitrate for video (kb/s)
--soft-target Use a large reservoir and treat the rate
as a soft target; rate control is less
strict but resulting quality is usually
higher/smoother overall. Soft target also
allows an optional -v setting to specify
a minimum allowed quality.

--two-pass Compress input using two-pass rate control
This option requires that the input to the
to the encoder is seekable and performs
both passes automatically.

--first-pass Perform first-pass of a two-pass rate
controlled encoding, saving pass data to
for a later second pass

--second-pass Perform second-pass of a two-pass rate
controlled encoding, reading first-pass
data from . The first pass
data must come from a first encoding pass
using identical input video to work
properly.

--optimize optimize video output filesize (slower)
(same as speedlevel 0)
--speedlevel encoding is faster with higher values
the cost is quality and bandwidth
- 0: Slowest (best)
- 1: Enable early skip (default)
- 2: Disable motion compensation
-x, --width scale to given width (in pixels)
-y, --height scale to given height (in pixels)
--max_size scale output frame to be within box of
given size, height optional (%d[x%d], i.e. 640x480)
--aspect define frame aspect ratio: i.e. 4:3 or 16:9
-F, --framerate output framerate e.g 25:2 or 16
--croptop, --cropbottom, --cropleft, --cropright
crop input by given pixels before resizing
-K, --keyint [1 to 2147483647] keyframe interval (default: 64)
-d --buf-delay Buffer delay (in frames). Longer delays
allow smoother rate adaptation and provide
better overall quality, but require more
client side buffering and add latency. The
default value is the keyframe interval for
one-pass encoding (or somewhat larger if
--soft-target is used) and infinite for
two-pass encoding. (only works in bitrate mode)
--no-upscaling only scale video or resample audio if input is
bigger than provided parameters

Video transfer options:
--pp Video Postprocessing, denoise, deblock, deinterlacer
use --pp help for a list of available filters.
-C, --contrast [0.1 to 10.0] contrast correction (default: 1.0)
Note: lower values make the video darker.
-B, --brightness [-1.0 to 1.0] brightness correction (default: 0.0)
Note: lower values make the video darker.
-G, --gamma [0.1 to 10.0] gamma correction (default: 1.0)
Note: lower values make the video darker.
-Z, --saturation [0.1 to 10.0] saturation correction (default: 1.0)
Note: lower values make the video grey.

Audio output options:
-a, --audioquality [-2 to 10] encoding quality for audio (default: 1)
use higher values for better quality
-A, --audiobitrate [32 to 500] encoding bitrate for audio (kb/s)
-c, --channels set number of output channels
-H, --samplerate set output samplerate (in Hz)
--noaudio disable audio from input
--novideo disable video from input

Input options:
--deinterlace force deinterlace, otherwise only material
marked as interlaced will be deinterlaced
-f, --format specify input format
--inputfps fps override input fps
--audiostream id by default the first audio stream is selected,
use this to select another audio stream
--videostream id by default the first video stream is selected,
use this to select another video stream
--sync use A/V sync from input container. Since this does
not work with all input format you have to manually
enable it if you have issues with A/V sync
Subtitles options:
--subtitles file use subtitles from the given file (SubRip (.srt) format)
--subtitles-encoding encoding set encoding of the subtitles file
supported are utf-8, utf8, iso-8859-1, latin1
--subtitles-language language set subtitles language (de, en_GB, etc)
--subtitles-category category set subtitles category (default "subtitles")
--subtitles-ignore-non-utf8 ignores any non UTF-8 sequence in UTF-8 text

--nometadata disables metadata from input
--no-oshash do not include oshash of source file(SOURCE_OSHASH)

Other options:
-P, --pid fname write the process' id to a file
-h, --help this message
--info output json info about input file, use -o to save json to file

nbtstat host not found - nbtstat problem

I encountered an issue when using nbtstat (netbios over tcp/ip) on a local network. On some computers, it seemed to work and others, it didn't. Unfortunately, google didn't help much so that's why I've decided to create this blog entry. I am using Windows XP. I was able to ping the machine and even remote desktop into it, but nbtstat didn't work.

This was the error message I was getting for nbtstat -a

Node IpAddress: [10.0.1.26] Scope Id: []
Host not found.

The address or remote name used in the nbtstat failed to return the host name or IP address.

Solution
I found the solution by doing a little tinkering.

1. Enable 'File and printer sharing' in the Firewall exceptions. This will open Port 139.
.


I still have the same problem with a Mac OS X machine I have. I'm not as experienced with Macs, so if anyone has any suggestions, let me know in the comments below.

Context Menu item - Run with Mono

Here's a very simple registry file you can import that will add 'Run in Mono' to your Windows Explorer context menu. Just right click on an executable and select the item. It will open the application using the mono.exe virtual machine.

You must modify the change the filepath in the run-with-mono.reg to point to your mono location. (Open the .reg file in notepad to make the changes.)

DOWNLOAD HERE (run-with-mono.reg)



Here's the finished result. I have not tested this extensively, so please report any problems here.

Unable to ping a computer on the network

If you have a problem pinging a networked computer, then it's likely a firewall issue. Sometimes a Windows service pack update may make the computer unable to be pinged by other computers. If the computer is still able to use the network, then try these things.

1. Try disabling the Windows firewall temporarily.
2. Are you able to ping the computer now? If so, then we know it's a firewall issue. Re-enable the firewall.

You may simply need to allow ICMP traffic in your firewall. ICMP enables a computer to be pinged.





Only the first setting needs to be enabled for pinging. The rest are optional and be kept disabled. More information about the other settings can be found at techtarget.com

You can enable ping on the command line by typing the below in the command line (start->run: cmd)

netsh firewall set icmpsetting 8 enable

Adobe InDesign - missing plugins Conditional Text.InDesignPlugin and WorldReady.InDesign

If you try to open up a CS4 InDesign file in Adobe CS3 or CS2, you'll get an error message saying "Unknown plugins prevent opening this file" or something of that sort. Those plugins are new features to InDesign CS4 and can not be used on CS2 or CS3. Simply because it's displaying that message, does not mean that those plugins were used on that file. It's just an error message that says the your version of InDesign (such as CS3) can not open up the file (CS4).

For some reason, this message pops up instead of telling you the file was created in a newer version of InDesign (Illustrator does tell you in a clear, user-friendly message).

The solution:
There's just two solutions, both of which aren't ideal.

1.) Request the sender to export the file as a INX format (InDesign Interchange) so that you can open up that file in previous editions of InDesign. If your local library or a friend has Adobe CS4 installed, you can open it up then as export in INX format. If the file contains features only available in CS4, then read on to the next step.
2.) Upgrade to Adobe CS4. If the file contains the new features from CS4, there's no other option.

Here's some discussion.

• Save Down From InDesign CS4 to CS3 with INX
  
• Unknown Plugins prevent opening files
