What actually happened?

HLS.js gets stuck and not download AAC segments again.

I am not able to reproduce the issue. The stream buffers and plays to the end for me.

Your logs show the stream buffering to the end despite empty audio segments. After buffering the entire stream and making the end:

base-stream-controller.ts:362 [log] > [stream-controller]: Loaded fragment 19 of level 0
bce2e1ca-b561-483f-a343-1fb4b0a90892:948 [log] > [transmuxer.ts]: Flushed fragment 19 of level 0
base-stream-controller.ts:1356 [log] > [stream-controller]: FRAG_LOADING->PARSING
base-stream-controller.ts:1356 [log] > [stream-controller]: PARSING->PARSED
base-stream-controller.ts:492 [log] > [stream-controller]: Buffered main sn: 19 of level 0 [0.000,84.400]
base-stream-controller.ts:1356 [log] > [stream-controller]: PARSED->IDLE
buffer-controller.ts:520 [log] > [buffer-controller]: video sourceBuffer now EOS
base-stream-controller.ts:1356 [log] > [stream-controller]: IDLE->ENDED

We then see a stall with a buffer for only 6 seconds.

gap-controller.ts:219 [warn] > Playback stalling at @5.949698 due to low buffer ({"len":0.06504000000000065,"start":0.00077,"end":6.014738})

The steps provided do not produce this behavior.

There is " DISCONTINUITY " tag in a/v playlist and the duration of stream is 84 seconds . I test it with native safari and hls.js v0.14.17 , and they can play to the end . With v1.2 , only play 6 seconds and freeze . I think it may be related to the logic of the silent frame compensation.

#EXTINF:5.991, 99.aac #EXTINF:2.000, 100.aac

#EXT-X-DISCONTINUITY #EXTINF:5.991, 99.aac #EXTINF:2.000, 100.aac ..... #EXT-X-ENDLIST

Files are the screen recording of v1.2 and v0.14.7

The second audio segment in each discontinuity does not have an ID3 timestamp. These segments samples should be appended right after the the previous segments and we do in older versions. However, if you seek into these segments we have trouble calculating start PTS (this is an issue in 0.14 as well). While testing this I also discovered an issue with how audio stream controller waits for init PTS from video. It does not reset waiting data on seek. #4847 fixes these issues.
