Updating VLC codecs on 0.8.6d

[loulou]

Hi,

I'm experiencing troubles in reading some HD mkv (h264 mostly) videos (either awful quality, either VLC crashing at launch) _with VLC_. I use VLC to stream the video which is read (Free's Freeplayer). My guess is that I can improve this situation with up-to-date codecs (typically because I already tried hard to play with the VLC command line options...) . Before going into the trouble of compiling the sources on windows of the current VLC version, I'd like to ask some questions:
- is it possible to use directly the plugin libraries for codecs from the snapshots of 0.9.0 into 0.8.6d? Is it meaningful at least (that is, there are improvements of these libraries in 0.9)?
- is the command line options of 0.9 backward compatible with 0.8.6?
- is there a way to compile VLC / VLC libraries to get the most of a given processor (in my case, Athlon X2 hence mmx/sse2/3dnowext support)?
- I've a h264/avc hardware decoder embedded in my graphic card (classical ATI radeon HD3450), but activating hardware overlay doesn't seem to improve anything on h264 decoding. Similarly, the card is supposed to offer hardware accelerator for divx/mp1/mp2 decoding, but no perf improvement. Is there something to do (possibly by means of compilation options) to use this processing unit for the decoding of videos? in 0.8.6? in 0.9?
- finally, in general, do you have any tricks to improve HD video decoding speed/quality/support? (I tested all of the ones I could find on the forum and wiki, nothing really improved my problem)

I also have a comment: for an unknown reason, decoding of mkv works on more files once I've installed the matroska pack. I assume only the splitter part is involved in this improvement, but anyway, do you have any hint why installing something influence video decoding support in VLC???

FYI, I run VLC 0.8.6d on a Win 2003 server, tested with no codec installed/ATI avivo codecs installed/avivo+matroska installed (current conf).

- No. Yes, it is.
- Yes, mostly
- Yes, but it is usually by default
- No. No and no. Ask ATI to open source their API
- yes, read this forum and read the good thread and use the latest NB.
