Unplayable mpeg ts after converting mp3 to mp4 with image and then converting mp4 to mpeg ts

Description

I am having issues converting an mp3 to an mp4 with a single watermark image and then converting that mp4 into mpeg ts for streaming.

I have a folder out on dropbox containing the mp3 as well as a shell script to demonstrate the problem as well as my debugging. You can get it here: https://www.dropbox.com/sh/r4zc39y68gwzt7f/AAD6X2i_JbAU6nASeXBt90mXa?dl=0

Note: all of the below commands are in the test_bug.sh

What I have observed is that if I convert the mp3 to mp4 with single watermark image then the resulting mp4 has a duration that is a little longer than the original mp3.
If I then try and convert this mp4 to mpeg ts then the last segment will not have an audio stream. ffprobe verifies this.

## Second experiment

I then modified my process to not include the watermark image. I found the resulting mp4 had a shorter duration than the output of first attempt. I then converted
it to mpeg ts and saw it was one segment less. All the segments had an audio stream and played just fine in vlc and quicktime.

ffmpeg -i mack_the_knife.mp3 -shortest out2.mp4 > third.log 2>&1
ffmpeg -i out2.mp4 -vcodec libx264 -bsf:v h264_mp4toannexb -strict strict -flags -global_header -dcodec copy -acodec copy -q:v 0 -map 0 -f segment -segment_list play2.m3u8 -segment_time 10 -segment_list_flags +live -reset_timestamps 1 -segment_list_entry_prefix 'http://localhost:8000/' ./%06d_2.ts > fourth.log 2>&1

# of note there is no 11_2.ts
ffmpeg -v warning -i 000010_2.ts -f null - > verify_good_segment_3.log 2>&1

This suggests to me that my mp3 is fine. The image is just an image so I don't know why it would change things so much.

## Third experiment

The mp4 duration changing concerned me. I then altered the first situation to specify the exact duration of the mp3 as reported by ffprobe.
The resulting mp4 had a duration closer to the mp3. I then converted the mp4 to mpeg ts and saw it was one segment less than the first attempt. The file was playable.

Please always test current FFmpeg git head before reporting issues here.
Either use -vcodec copy or the bitstream filter, I don't think using both is supported.
What are you expecting to find in the last segment?
