  oups, correction :
  la propagation du env melangeait les parametres du menu avec le env, ce qui entrainait des effets indesirables.
  On isole le env dans une entree env du contexte du menu, et on expose aussi le menu dynamique

• How to get memory location in C# while using structure of C [on hold]

  12 août 2017, par Nirmal

  I am using C# to record a video from IP camera and I am using libavcodec57 library for that. So if I need to write or read any property of a structure I need to use Marshal class in C#, like

  int width = Marshal.ReadInt32(in_codecctx, 40);

  In above in_codecctx is of type IntPtr which points AVCodecContext structure in C. So there are many properties in that like width, height etc and to read I need to use above line of code and for that I have to know the address of that property in the memory, which is base address of structure plus offset to that property. Base address I know but how to find actual offset of any property.

  One way is, I need to create same structure in C# which is defined in libavcodec library and use below code, this will give me offset of width from structure defined in C#.

  Marshal.OffsetOf(typeof(AVCodec.AVCodecContext),"width")

  But this needs great efforts and still not accurate as it gave me some wrong values.

  This link is for structure I need to use, is there any way to identify the offset of width and height, if yes how ?

• creating simple DVD structure ?

  24 mars 2016, par Rambo Actionha

  I’m trying to make a DVD builder using C# , and I know that DVD’s have a specific structure which I tried to find and I couldn’t see any thing helpful , however , I found some half-completed posts about this structure , which indicate the following :

  • all DVD videos must be in ’.VOB’ format
  • all DVD Videos must be in a folder named "VIDEO_TS" and DVD audios in a folder named "AUDIO_TS" (specifically)
  • "VIDEO_T" and "AUDIO_TS" must be burned to a DVD disk that follows a special filesystem called [UDF][1]

  My question is If I managed to convert my video to suitable ".VOB" format , then I burn it to a disk after adding it to those folders , would it be playable in any DVD player ? I mean is this enough to have a simple DVD disk , and if it wouldn’t .. what would be the simplest DVD structure I can make ( without menus and chapters and other extra stuff ) ? any links related to DVD would be great
