Cowon d2

It has taken some effort to figure out what format video can be displayed on the D2.

There are two places that files can be dropped, the video folder or the flash folder. If the file is not in a proper format, it doesn't even appear in the list of options in the media player.

things that work

• bible lesson in WMV format dropped in VIDEO folder (nice small file size)

090111_902wbl_wm_225k_1047.wmv: Microsoft ASF

VLC describes this format:

Stream 0

Codec: wma2

Type: audio

Channels: 2

Sample rate: 32KHz

Bits per sample: 16

Bitrate: 32 kb/s

Stream 1

Codec: wmv3

Type: video

Resolution: 320x240

• bible lesson in AVI format dropped in VIDEO (the web pages calls this Mpeg 4 video, requires Divx codec)

090111_902wbl_divx_video_1047.avi: RIFF (little-endian) data, AVI, 320 x 240, ~30 fps, video: DivX 5, audio: MPEG-1 Layer 3 (stereo, 24000 Hz)

Here is what VLC says about this file format:

stream 0

codec: dx50

type: video

resolution: 320x240

framerate: 29.97

stream 1

codec: mpga

type: audio

channels: 2

sample rate: 24000 Hz

bitrate: 56 kb/s

things that don't work

• bible lesson in ipod quicktime mp4 format

090111_902wbl_ipod_video_1047.mp4: ISO Media, MPEG v4 system, version 2

• youtube videos in flv format (tried putting them in both flash and video folders)

Atlantic_Salmon_Webcam.flv: Macromedia Flash Video

So why is there a flash folder, if flash isn't recognized? The technical specs don't mention flash videos.

According to the published specs, these are the only video file formats supported:

AVI : MPEG4 ~ 2Mbps, 320x240, 30fps, MP3 audio
WMV : WMV9 ~ 768kbps, 320x240, 30fps, WMA audio

This works if I start with a Flash movie as the source

:sout=#transcode{vcodec=WMV2,vb=800,scale=1,acodec=mp3,ab=128,channels=2}
:duplicate{dst=std{access=file,mux=asf,dst=presto.wmv}}

However, if I start with a DVD VOB, it crashes VLC

• encapsulation: asf/wmv
• video codec: wmv2
• audio codec: mp3
• result: unknown

This also works if I start with a Flash movie as the source. This crashes VLC if I use a DVD VOB as the source.

• encapsulation: mp4
• video codec: mpeg-4
• audio codec: mpeg audio
