Expanding a bit I copied one of the files to a test directory to play |
25 |
with. It seems smplayer will actually play the audio but won't display |
26 |
video. midentify gives some data. When I look at the ffmpeg info it |
27 |
seems to me it's also having trouble with the video portion. At least |
28 |
it seems to understand the audio portion. |

I'm guessing the pivot point here is the video format code: |
31 |
|
32 |
ID_VIDEO_FORMAT=MSS2 |
