MPEG2 (MPEG2P) rendering crashes

dzhou_tac — Mon, 11 Jan 2010 20:34:23 GMT

Hi,
I have a video clip, it is MPEG2 (MPEG2P) stream type. It can be rendered without error under MS-MediaPlayer. But when it is rendered with simple_player.exe, it triggered an exception:
An unhandled win32 exception occurred in simple_player.exe [3856]

I also use my own code with IPP data reader, splitter, and decoder. But in the middle of the stream, it seems missing some macro-packets (with less resolution in the middle of s few frames). But it ends properly.

The simple_player displays:
Video Render: DX
-RenderFormat: YV12

Stream Type MPEG2P
Video Info :
-Video Type MPEG2
-Resolution: 720x576
-Frame Rate: 25.00

Any suggestions? If you need the clip for testing, I can send it to you.
Thank you,
david.tac

David,
the list of fixed problems doesn't contains such issue.Probably this is an unknown issue.
Could you attach the stream you are using and the options of command line?

Gennady,

The Intel_T90.pgm crashes at or near the end.

Intel_dish301.ts audio repeats for every decoded frame. Something like: AA BB CC, while it shuold be A B C.

Thank you

The command option is:
-L "C:tempPlaylist0.txt" -v dx
the Playlist0.txt contains the stream file to be played.
