 Summary of the bug:

 Trying to use ffmpeg to do a real-time stream copy of a stream that
 contains a HEVC video stream and three audio streams.  No matter what I
 do, ffmpeg will copy the three audio streams with no problem (verified by
 using mediainfo) but it refuses to copy the HEVC video stream, even though
 it acts like it is doing it.  Even using a syntax that specifically maps
 the video stream, such as

 ffmpeg -i infile.ts -c:v copy -map 0:0 -c:a copy -map 0:1 -map 0:2 -map
 0:3 outfile.ts

 does not help.  I get all the audio streams but no video.  If I specify
 anything other than copy after -c:v then it works but it is too slow to
 use in real time.  My eventual goal was to try to add the "Display aspect
 ratio : 16:9" attribute to the video stream metadata (otherwise the video
 is half height) but obviously that can't happen until the video stream
 gets copied.  I've seen this issue in at least three different versions of
 ffmpeg (4.4, 6.0, and the nightly version shown below). More info on this
 issue is at
