Streaming to STDOUT remains empty

[Niklas Mollenhauer]

We're trying to stream the output to ffplay.
However, it seems that the video stream remains empty. When piping the output to a file, the resulting file is empty, too.
Streaming to an MKV fifo works. When starting the program with -debug, there is a lot of output.

I'm not familiar with the code base, but it seems to me that videowriter remains unused when passing -mkv=false.

de-ip-hdmi/main.go

Lines 57 to 61 in 632f157

 	go DumpChanToFile(videodis, videowriter) 
 } else { 
 	videowriter = os.Stdout 
 } 
  

As a blind guess, I think the line go DumpChanToFile(videodis, videowriter) should actually be placed below the if/else block (line 61).

If this is not the problem, how can we narrow the problem down?
