pl_mpeg + physfs = possible?

[Jarrod Davis]

Hi, I'm looking around for a video playback solution and considering pl_mpeg. Can it be made to work with physfs?? I'm currently using physfs to load resources from a zip archive, so I need to be able to also play the videos from this archive as well. At present I don't see a way to easily do it. Maybe I've overlooked something, please advise.

Thanks

Jarrod

This is absolutely possible!
It mostly comes down to using plm_create_from_memory and then handling the file read yourself using the physfs API.

For a little bit of a jumpstart, I went ahead and modified the video player example from this repository to use physfs instead, to demonstrate how to join these libraries better :)

@alichay Oh, sorry, just noticed your reply. Ok, I will check this out. Many thanks! 👍🏿

Actually, if you use the buffer interface, then you can read in chucks at a time and not have to load the whole thing into memory.

procedure plm_buffer_load(buffer: Pplm_buffer_t; user: Pointer); cdecl;
const
  LBufSize = 1024*2;
var
  LBuff: array[1..LBufSize] of Byte;
begin
  if PHYSFS_eof(Phys) <> 0 then
    begin
      if plm_get_loop(Plm) = 1 then
        PHYSFS_seek(Phys, 0);
      else
        plm_buffer_signal_end(buffer);
    end
  else
    begin
      PHYSFS_readBytes(Phys, @LBuff[1], LBufSize);
      plm_buffer_write(buffer, @LBuff[1], LBufSize);
    end;
end;
