process freezes rtsp remux hls (cur_dts is invalid st:0 )

[jidckii]

Summary of the bug:
I park streams from ip cameras over rtsp and remux them to hls.
I have several cameras from which ffmpeg cannot do remux in hls or mpegts.
It looks like the process freezes and does nothing

I run approximately the following command

ffmpeg -loglevel debug  -rtsp_transport tcp -stimeout 10000000 -use_wallclock_as_timestamps 1 -copytb 1 -i rtsp://admin:123456@127.0.0.1:5554/profile2 -ss 1-vsync -1 -map 0:0 -c:v copy -map 0:1 -c:a aac -async 1 -f hls -use_localtime 1 -hls_time 2 -hls_list_size 5 -hls_flags delete_segments+second_level_segment_index -hls_segment_filename %M%S_%%03d.ts ffmpeg-index.m3u8 -report

there are a lot of such errors in the output

cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)

mux does not start, while it is possible to send ffmpeg to the SIGTERM process, then it ends and at the same time muxes the last data that was in the buffer. ts chunks and an index file appear in the directory.

I also recorded a minute fragment in TS format, errors are reproduced
