Hi Stroller, |
27 |
I subscribed to a trading service that provides 6 1/2 hour videos |
28 |
of the day's market action with audio commentary for each trading day |
29 |
of the week. I like this trader who does the commentary so after the |
30 |
market closes I'd like to review what he thought about the day's |
31 |
action. These files are available only in wmv format. They play fine |
32 |
inside of a Windows VM using Windows Media Player on my Gentoo box but |
33 |
I'd prefer to be able to review them in Linux using xine or some other |
34 |
app. |
35 |
|
36 |
The quality of the video and audio isn't real high to begin with. 6 |
37 |
1/2 hours and they only run about 50MB each. I don't think converting |
38 |
to mp4 would cause me much concern. Additionally if they are mp4 I |
39 |
could watch them on my Kindle Fire. |
40 |
|
41 |
So far I've been unsuccessful with the mencoder suggestion. I'll |
42 |
keep plugging away as I think I'm done with trading today anyway. Big |
43 |
move. Caught most of it. Good to take a few minutes off. |
44 |
|
45 |
Cheers, |
46 |
