Comment (by John Coiner):

 To reproduce, use the attached file and run:

 {{{
  $ ffmpeg -re -i sample_input_ffmpeg_bug_10148.ts -codec copy -f hls
 -method PUT
 'https://upload.youtube.com/http_upload_hls?cid=<<YOUR_STREAM_KEY>>&copy=0&file=out.m3u8'
 }}}

 (Is there an option to capture HLS output to local files? That'd work too;
 certainly uploading to YouTube should not really be necessary to check
 this. Just upload to any webserver that accepts PUT/POST.)

 This upload a few HLS chunks. Only the first chunk is independently-
 decodable, all others are missing their SPS/PPS due to the bug. With the
 suggested fix, all chunks include SPS/PPS.
