various compile hiccups

[frueter]

I managed to compile successfully but ran into the following issues:

• www.nasm.us is offline so I could not download nasm-2.15.05.tar.bz2 elsewhere
• ffprobe_lib.cpp:105:35: error: ‘av_mallocz_array’ was not declared in this scope; did you mean ‘av_malloc_array’?
  to fix I renamed the av_mallocz_array to av_malloc_array
• ffmpeg_stream.cpp:573:42: error: ‘AV_CODEC_FLAG2_DROP_FRAME_TIMECODE’ was not declared in this scope
  to fix I declared it with value 1 (not sure if that is the correct thing to do though)

I'm no coder but after the above I could compile and open xStudio ok.

re AV_CODEC_FLAG2_DROP_FRAME_TIMECODE. You probably got this because you were trying to compile with ffmpeg 6 instead of 5. AV_CODEC_FLAG2_DROP_FRAME_TIMECODE was deprecated and xstudio probably needs a re-write here to ensure dropframe/non-dropframe timecode is working properly under the hood.
