|Linux Video and DVD Players:
There are plenty of Linux Video applications for playing and editing various video file formats, codecs and media (VCD, DVD).
Trouble with a particular codec is often resolved by upgrading to a newer version of the player or choosing a different player.
I find that the system default is NOT always the best choice.
DVD,-RAM provides 4.7 GB per side storage. The average DVD
movie can hold up to 5GB of data. There are currently 6 forms of copy
protection which apply to DVD's.
CSS: Content Scrambling System is used by the entertainment
industry to provide copy protection. Each CSS licensee possesses one
key (of an available 400) which is stored on the CSS encrypted DVD.
Most DVD's are encoded with Macrovision copy protection.
CSS can employ CPPM (Content Protection for Prerecorded Media). This
adds the concept of renewability and revocation. CPRM (for recordable
media) support is supported by all DVD recorders released after 1999.
Each blank recordable DVD has a unique 64-bit id. When protected
content is recorded onto the disk, in can be encrypted with a cypher
derived from the disk ID. During playback, the disk ID is read and used
to generate a key to decrypt the contents of the disk. If copied to
another disk, the id will be absent or incorrect and thus not
DTCP (Digital Transmission Copy Protection) allows for the exchange of keys between players, digital TV's and other devices.

|Nonlinear Video Editing Software:
Fully integrated video editing GUI suites are available for Linux.
The integrated GUI environment tends to be developed independently of the libraries which support the various codecs.
I find that choosing the library which is at the foundation of the application is ultimately what defines the experience.

[Potential Pitfall]: AVCHD MTS format video gets out of sound-video sync when output by the video editor even though the input MTS file was in sync.
It also seems like many of the video players like vlc can't even play the MTS video format without the sound and video being out of sync.
I find that mplayer will play the video and sound in sync but its related mencoder program does not seem to convert MTS to an output file and format which remains in sync.
Luckily ffmpeg seems to do the trick.
Try: ffmpeg -i 00038.MTS -f avi -b:v 16000k -b:a 192k 00038.avi
This will result in a much smaller file size and there is some notable reduction in video quality.
Also: ffmpeg -i 00038.MTS -f avi -vcodec mpeg4 -b:v 17104k -b:a 384k 00038-ffmpeg-2.avi
(What I specified for my Sony Nex-5 MTS video format.)
- -i = input file
- -s = size eg "-s = 1280x760" Place after input file specification.
- -f = format, appeared neccessary
- -b:v = videobitrate A larger number inflates the file size. A low number decreases the file size but also reduces quality
- -b:a = audiobitrate

|View TV/Listen to FM radio on Linux: (w/ Hauppauge WinTV PCI)
||Hauppauge model 447 WinTV PCI card: This PCI card integrates
a cable ready (also aerial, satelite, video, S-video) television tuner
(125 channels), video capture and an FM radio tuner.
The product includes an infrared remote and a color video camera.
(Newer versions also ship with headphones with mic and volume control)
It is based on the bt 878 Brooktree chip-set.
I installed a Hauppauge model 447 WinTV PCI card and Kudzu
detected it upon system boot and made the appropriate system configuration
changes. No further system configuration changes were required.
Kudzu added the following line to the file /etc/modules.conf:
- alias char-major-81 bttv
The following devices are supported by the WinTV card:
- /dev/radio - FM radio
- /dev/vbi - TV call sign data
- /dev/video0 - TV
How to generate devices if they did not get generated properly:
[root prompt]# mknod /dev/video0 c 81 0
[root prompt]# mknod /dev/video1 c 81 1
[root prompt]# mknod /dev/video2 c 81 2
[root prompt]# ln -s /dev/video0 /dev/video
The following modules are loaded:
- videodev.o: The video4linux device module
- bttv.o: Driver for the Hauppauge card.
- i2c.o: Interface for bus to framegrabber.
- tuner.o: Tuner module to switch chanels.
- msp3400.o: Stereo
I then installed speakers on the audio output of the WinTV card and the
cable TV coax to the cable TV/antenna input.
Audio may be configured one of three ways:
- Connect speakers directly to the WinTV "Line Out" connector. (Use amplified speakers.)
- Connect the WinTV "Line Out" to your sound card "Line In" connector on the
rear of your computer.
- Use the "internal" connector provided to internally connect the WinTV card
to the internal "Aux In" on the sound card. This connector looks like the
connector which connects the CD to the sound card internally.
When using this method use the sound controls provided in KwinTV.
Note: The graphics card displays the image generated by the WinTV card.
Thus they must communicate together. The graphics card must support
"Primary Surface Mode" (write to graphics card display memory. Modern video cards do.) or your
computer must have loads of memory to hold the video image.
Video capture/encoding using Real Producer:
YoLinux Real media tutorial: Real Producer video capture/encoding - Using the Hauppauge WinTV PCI card
TV Viewing Software:
Tested on Red Hat 7.1. My preference is KwinTV. I have read that deficiencies
in the i2c.o driver necessitate that only one application access the Hauppauge
card at a time or risk eeprom damage.
I installed Red Hat (7.1) RPM kwintv-0.8.5-5
Using kwintv: (The following directions are USA broadcast specific. Other broadcast standards are supported by KwinTV)
That is all there was to it! It was so simple. KwinTV can perform image file
to a series of PPM image files (View with xv), video capture to an AVI file
(View with xanim) and capture snapshots to a JPEG, PNM or PNG file.
- KwinTV home page
- Start kwintv: /usr/bin/kwintv
- Scan stations: (Not necessary)
- "Program" + "Widard" (Next)
- Select "NTSC" (Next)
- Unselect "Scan whole frequency band" and select "USA cable" (Next). If using an antenna select "broadcast".
- Select "Start". After scan is complete select Next.
- Select "Finish"
- Configure channel selection:
- "Program" + "Browser"
- Select leftmost icon which is "Add new program"
- Select a channel
- Set "recieving region" to "USA [cable]" (USA residents)
- Set "input video format" to "NTSC" (USA residents)
- Set "input source" to "Television"
(Note: Set to S-Video to view input from color video camera
which comes with the Hauppauge WinTV PCI card or S-Video camcorder. )
- Assign it a "program name" (i.e. NBC, CNN, etc)
- Select "OK"
- Keep adding new programs till your viewing selections are complete.
- Up/Down arrows change channels.
- KwinTV channel configuration file: $HOME/.kwintvrc/default.ch
- Use your camcorder as your video source and then you can use KwinTV
to video capture (channel 3/4) the analog input to AVI.
- TV viewing software uses /dev/video0
- To exit the application type the letter "q" for Quit.
- The BT848 chipset converts the input from the TV tuner to a digital
YUV 4:2:2 sampling (24 bit RGB) for display by the VGA graphics card.
- Want to play your console video game and display on your computer?
Plug the output of the game console into the Composite Plug on the TV card.
Radio Shack can sell you an adaptor for Left/Right audio of the console
to the Line-in plug of the sound card.
- VCR's and camcorder will also be able to feed the TV card.
[Potential Pitfall]: KwinTV supports
infrared remote controls but I could not get it to work.
See: Linux Infrared Remote Control (LIRC) Project
While playing with XawTV I messed it all up and the screen setting
was too dark. To fix this condition, launch KwinTV and select
"Program" + "Browser..." (or the program browser icon).
Select the channel and select the edit icon.
Then select the options tab and reset the contrast/hue/brightness/color.
- Zapping: (Easier to use but less capable than KwinTV. Unfortunately it is also more buggy.)
It's that simple. The advertised video capture and image capture did
not work for me. The closed captioned text worked well.
- Zapping home page
- Download: Zapping, a Gnome TV viewer download page
- Install: rpm -Uvh zapping-0.6.0cvs-1.i386.rpm mp1e-1.9pre1-1.i386.rpm
- Select "Settings" + "TV Channels"
- Select "us-cable" (or appropriate setting)
- Select "Search for available channels in the current country"
This scans and loads the channels into the GUI.
- Select "OK"
Obtains station call sign info/id from device: /dev/vbi0 (cool feature)
[Potential Pitfall]: Over time it tends
to operate slower and slower if attempting video capture. (Bug)
It will eventually hog the full resources of your computer.
[Potential Pitfall]: Often exits
poorly leaving processes running. Kill processes before restarting.
- XawTV: (NOT recommended)
Not pretty (in fact it's ugly) but it is complete.
I found that it was not very reliable and behaved flakey at times as it
responded strangely to the controls.
i.e. contrast/hue/brightness settings would suddenly and randomly go
to zero upon a
channel change and I would loose the picture, tuning would be inacurate and
fuzzy, the window would scroll etc.
- XawTV Home Page
- Download: XawTV
Includes the /usr/bin/radio console program which works with
the Hauppauge WinTV/radio card.
- Start program: /usr/bin/xawtv
- Press "Enter" (Enter/Carraige Return)
- Press right mouse button to bring up menu. Do it again to toggle it off.
- Select "TV Norm" and select option "NTSC". If the screen scrolls out of frame do this again to correct the picture.
- Select "Frequency table" and select option "us-cable"
- Select "Channel Editor" (or press letter "e")
- Change channels by selecting the UP or Down arrow.
Note: Cursor MUST be in the "Channel" data entry field or
in TV viewing screen.
- Give the channel a name (i.e. Fox-TV) and select the "Add" button.
I do NOT recommend this TV viewer!!
Configuration file: $HOME/.xawtv
Video capture file sizes:
||One Min video
- NTSC frame ratio: 4:3 or 640x480 resolution at 30 full frames/sec (60 half frames/sec interlaced).
- NTSC displays 480 horizontal scan lines (The NTSC standard
refers to 525 total including non-visual data such as closed caption
text and 511-525 blank. Theoretical resolution: 720x525. Theoretical
bandwidth: 27 Mb/s uncompressed.)
- Video devices often degrade the 480 scan lines to:
- VHS video tape: 240
- S-VHS: 420
- Broadcast Cable: 330
- Satelite: ~400
- DVD: 500
- Laserdisc: 420
- PC quality video: (typically)
- NTSC: 352x240
- PAL: 352x288
- Movie Theater frame ratio: 16x9 at 24 frames/sec
- HDTV: 1080 horizontal lines x 1920 vertical lines (1920x1080)
- PAL/SECAM: 4x3 frame, (x625 theoretical total), 25 frames/sec, 50Hz, 50 half frames/sec interlaced.
- Broadcast NTSC MPEG-2: 720x486, 15Mbits/s
- Hauppauge video capture 320x240 (Want to do better, go HD digital and firewire)

Applications for TV cards with an FM tuner onboard:
- DengerinRadioFM: Simple, allows station presets.
- http://oss.mdamt.net/radiofm/ - DengerinRadioFM Home Page
- Execute: /usr/bin/radiofm
- Configuration file for preset stations: $HOME/.radiofm
- radio: Part of xawtv-3.34-1 TV viewing RPM. Text console program. It works. See radio man page.
- Gnomeradio: Gnome desktop radio
Did not try these:
- fmtools - programs for Video for Linux radio cards
- gTuner - GNOME radio controller
The Hauppauge XC77B/44x Webcam:
The webcam which ships with the Hauppauge model 447 connects to the cature
card with an S-Video connection. This should be superior in bandwidth to a
USB attached webcam.
Test the webcam: I used kwintv and Zapping.
This test will allow one to view video from the webcam on the desktop.
- Select from the tool bar "Program" + "New".
- Select from the pull-down menu "Input source" - "S-Video"
- Watch yourself on kwintv.
- Zapping: Change the pull-down selection on the tool bar from "Television"
For capturing video for Real Media streaming see the YoLinux tutorial on
If trying to find a power connector which is compatable with the Hauppauge
VCM77 video camera, use the
Radio Shack TA-910-5272.
(DC inline jack OD 5.5mm x 2.5mm)
This is a special order part. I found that my computer would not
boot properly when the Hauppauge power cable was used in-line with the PS/2
Beware of the little "universal" power supplies which can provide multiple
voltages. Use a volt meter on any voltage supply first!!! I fried a camera
believing the voltage setting on one of these cheap power supplies. It
was putting out twice the displayed voltage!!!
The only voltage I trust is the PC power supply.
It can supply 3.3, 5 and 12 volts. The Hauppauge video
camera requires 5 volts. The outer cylinder is negative while the center
post is a positive 5 volts. The red wires from a PC power supply are typically
5 volt lines.
Newer versions of the model 447 ship with the Pixera PXG-100 (N-NTSC or P-PAL)
which uses a different power connector.

Installs the following packages (Ubuntu natty): ekiga libopal3.6.8 libpt2.6.7 libsrtp0
This tutorial covers Gnome Meeting 0.85.1 on Red Hat Linux 7.2.
Gnome meeting is compatable with Microsoft NetMeeting.
GnomeMeeting supports audio, video, text chat and audio only conferencing over the internet.
It requires connecting to an ILS server to allow each video conference user
to locate each other and negotiate acceptable protocols.
(A default is provided.)
Red Hat/CentOS/Fedora: (Four RPM's were installed)
- Use Kwin TV to set the defaults on your video card. Gnome meeting does
not do this well. You may end up transmitting CNN by mistake
instead of your own video. The Hauppauge card seems to use the last setting.
Using KWinTV, you need to set the S-video input as a channel - the lowest
Do this by first tuning to the lowest channel and then add a new channel
set to be the S-video input. This will set channel 1 to be the S-video.
(KWinTV: "Program" + "Browser...". Select the "Add new program" icon.
Select "Input video format"=NTSC, "Input source"="S-Video" and assign
it a "Program name" i.e. "Camera". Then select "OK".)
Exit/Quit KWinTV and then set Gnome meeting to channel 1.
("Edit" + "Settings" + "Device Settings" and set "Video Channel" to "1".)
- Configure Gnome Meeting: "Edit" + "Settings":
- Configure "Personal Data": Select ("Edit" + "Settings") + "Personal Data"
Enter data and select "Update".
- Configure "Directory Settings": I used the default ILS Directory argo.dyndns.org then select "Update" to notify the LDAP server.
(Alternate ILS: gm.uk.linux.org)
- The default in Gnome Meeting is video turned off. To turn it on select:
("Edit" + "Settings") + "Codecs Settings".
Select the tab "General Settings".
Depress the button "Video Transmisson" before connecting to the LDAP video
- "Device Settings": Set "Video Format" to "NTSC" for the
USA crowd. PAL for the Europeans. The "Video Channel" should be set to
that matching your S-Video chanel set in KWinTV as described above.
- Select the Gnome Meeting "Book" icon to bring up the LDAP server browser
- select the pull-down menu and select the ILS server argo.dyndns.org
and select "Refresh".
- Right click to pick the person to connect to.
GnomeMeeting screen shot
- Audio mixer must have the mic un-muted. (/usr/bin/gmix)
- My headset also has a microphone mute button on the cord - check it.
- Slow networks will require one to reduce the number of
frames sent per second (i.e. 1 or 2) or reduce video quality in order
to preserve audio rates.
- Firewalls are said to be a potential problem according to the GnomeMeeting FAQ.
Note for Microsoft Windows XP users: Start Netmeeting: "Start" + "Run" + conf.exe
