Crash in BSplayer with libmpeg2 / ffdshow

[Flag]

The problem has always been present in all versions of BSplayer but actually I use BSplayer Pro v.2.26.956 (with Athlon XP, Windows 2000 Pro, NVidia 6600 GT)

Whenever I want to use libmpeg2 for decoding MPEG or MPEG2, the player crash with an invalid floating point operation.

That problem arise only when using BSplayer. With other players, like Windows Media Player 6.4 or Media Player Classic (with ffdshow doing the decoding) for example, libmpeg2 works wonderfully.

MPEG/MPEG2 decoding with libavcodec (ffdshow) don't show that problem but when coming time of doing DVD decoding, libavcodec doesn't work well (that is a problem with ffdshow because it behaves the same with any player) whereas libmpeg2 does a great job.

Don't tell me to use another MPEG2 decoder. I know I can do that but I prefer the settings available in ffdshow that are not in other decoders. For DVD decoding, libmpeg2 should be the right choice. It's just that with the very specific combination of BSplayer and ffdshow, with MPEG-2 and DVD decoding activated, I get a crash. Until it get fixed, I have to use another player for DVD decoding :(

Just in case, I tried changing the video rendering mode but got no change.

I've had no problems with ffdshow 'beta3' together with BSPlayer 1.36. I'm using a single core processor, so maybe it would crash only on dual.

You should give the details about your system for comparaison. Do you have an INTEL CPU? What OS?

BTW, an AMD Athlon XP is a single core CPU.

I have Pentium 4 '506' w/o HT at 2.66 GHz, GA-8I915P Duo motherboard, 2 GB DDR2 RAM at 200 MHz, ATI Radeon X550 with Catalyst 7.1, WinXP SP1.

ffdshow 2007-07-01 (build 1324). It is being used to watch VOBs and MPEG-2 in Matroska, but not DVDs.

I got ffdshow beta3 (stable) also and BSPlayer 1.38. Things are working well.

I tried with ffdshow 'beta3', "beta 4" and "beta4a". I get the very same problem. BSplayer crash every time I select libmpeg2 for MPEG/MPEG2 decoding. That doesn't happen with any other player (with ffdshow doing the decoding).

Beside that problem, if I select libavcodec for MPEG2 decoding and the DVD decoding check box in ffdshow, BSplayer reads well MPEG2 files (including VOB files) when opened directly but for some reason, if I ask BSplayer to open the same file through the "open DVD" feature, it reads it in a very jerky way.

Could those problems be related to the CPU (AMD Athlon XP) ??

[J7N]

Yes you are right. Here it also opens some DVDs like at half the framerate (jerky way).

And wich is the DVD decoding filter used ? (DVD source)
