I have a VOB file that I need to convert to something playable on a Sony Walkman NWZ-E344.
The walkman wants an ASF container, resolution of 320x240 (or less), wmv9 codec, wma 2 codec, 30 frames per second, video bitrate of less than or equal to 768k.
I cannot seem to get a mencoder (nor ffmpeg) encoding line to work.
Here's some data on a video that works:
$ ffmpeg -i Butterfly.wmv
....
[wmv3 @ 0x29707c10]Extra data: 8 bits left, value: 0
Seems stream 1 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, asf, from 'Butterfly.wmv':
Duration: 00:00:08.21, start: 5.000000, bitrate: 1126 kb/s
Stream #0.0: Audio: wmav2, 44100 Hz, stereo, s16, 96 kb/s
Stream #0.1: Video: wmv3, yuv420p, 320x208, 768 kb/s, 29.97 tbr, 1k tbn, 1k tbc
mplayer -identify Butterfly.wmv

"What did you do?" the man holding the flashlight asked.
"I put down a spider," he said, wondering why the man didn't see; in the beam of yellow light the spider bloated up larger than life. "So it could get away."
