Subtitles cannot be copied in copy/conversion process

[bivinix]

Using Windows 10 64-bit with:

ffmpeg version N-93863-g58d167bcd5 Copyright (c) 2000-2019 the FFmpeg developers

built with gcc 8.3.1 (GCC) 20190414

Attempting to copy/convert a Blu-Ray sourced video, which is broken up into many M2TS files. When processing, I get hundreds of messages like this:

Non-monotonous DTS in output stream 0:2; previous: 291274410, current: 291274408; changing to 291274411. This may result in incorrect timestamps in the output file.

The resulting file has the audio/video tracks but the subtitles show up as "Data: bin_data" streams.

My command-line looks like this:

ffmpeg.exe -y -i "00370.M2TS" -map 0 -c:v copy -c:a copy -c:s copy test.m2ts

This can be reproduced with the first tile in the playlist (as described in the command line above). It is about 200MB.

The "bin_data" streams also generate an "unsupported codec" warning in ffprobe.

You need to provide a sample for this.
