Full Version: mp3/mp4
my mum bought a 1gb usb. i am not really sure if it is mp3 or mp4 because it reads on the case mp34 and the 4 is kinda slighted downwards. as mentioned in the manual it should have a option as movie mode, but i am shocked not to find that icon in the display. i have tried softwares such as WinAVI MP4 Converter but unfortuntely have not been sucessful in playin. the person whom my mum bought this from said that this could play visual media. i would be grateful if any1 could help me fix this problem.

Chinese MP4/MTV Player is a flash based Digital audio player, mostly manufactured in China, capable of viewing images, videos, and text files. Although commonly called MP4 players, they are unable to play MP4 format videos and are limited to proprietary file formats such as MTV, DMV, MPV and AMV. They are a kind of the S1 MP3 Player.
[edit]
General features
Picture viewing:- JPG, BMP and some others depending on model.
Video: AMV or MTV and other file formats depending on model.
Music: MP3 and others depending on model.
EBook viewing and Text (normal ascii .TXT format).
Phone Book facility: format in which they are created depends on the model.
Built-in FM Tuner on some models
Voice and Radio record.
Games. Depending on model.
Each directory can hold upto 99 items (anything higher depends on model).
Devices may and in some cases, must be charged via the computer's USB port while on.
Software on Micro disk with drivers for Windows 98 and below
Battery life of several hours, though differing depending on usage (e.g, playing video gives lower battery life than audio)
[edit]
Design
Some are tiny (1.2 inch screens) and very light weight without internal speakers. Others are more robust in design (1.5+ inch screens) with additional facilities like built-in speakers and two earphone sockets. Most players feature a 65k OLED display which produce brighter color images than LCD displays, though the image quality is generally quite poor. Normally supplied with micro Stereo Ear phones, USB lead and driver disk (and possibly charger). Some may also be supplied with a special carrying case. It should also be noted that the covers of some players is of low quality and the screen parts of these covers crack easily. There are many complaints about this issue all over the world.
[edit]
Operations
In general, it is simple to operate with some buttons with multiple actions, like play, stop, Enter etc. (in one writer's experience of one player, the MENU button usually invokes both menus and navigates into folders, with the PLAY button completing an operation). Some have additional buttons on the side of the player, while others stick to a 'Star' configuration at the bottom of the screen, with a single selection button or Joystick in the center of the Star.

Supported File formats
[edit]
MTV Video Format
The MTV Video format was created to allow video playback capabilities on inexpensive mp3 players without increasing the cost of those players. The format operates by displaying a series of raw image frames while playing MP3 audio.
The MTV format consists of a 512 byte file header, followed by alternating image and audio frames. While the audio frames are encoded with MPEG1 Audio Layer 3 (aka MP3), the image information is stored in uncompressed raw format, according to the player's display hardware specification.
During decoding of the video stream, the audio frames are passed to the mp3 hardware decoder, while the memory pointer of the display hardware is simply adjusted to the next raw image within the video stream. While this concept does not require additional * hardware for the decoding process, it leads to huge memory requirements as no compression is applied to the image information. For this reason the storage capacity of an MP4 player is effectively much less than that of a player that decompresses files on the fly.
[edit]
AMV Video Format
When playing AMV formats, there is clearly some image de/compression taking place, as can be demonstrated by a simple calculation (AMV video format). The image compression is, however, low by modern standards (around 4 pixels/byte, compared with over 10 pixels/byte for MPEG2/DVD). With a resolution of 128 x 96, and a frame rate of 12 fps, a 30 minute file will be around 80MBytes in size.

ACT Audio Format
some MP4 players have the ability to record relatively low-quality sound through an inbuilt microphone, or directly from their FM receiver. This sound is generally recorded in WAV format, or ACT format)-].
