[NULL @ 0x25fb220] ct_type:0 pic_struct:2
timestamp discontinuity -10080000, new offset= -14766634989
[hls @ 0x262ab20] Delay between the first packet and last packet in the muxing queue is 10020000 > 10000000: forcing output

after these messages sound lost and i have to restart ffmpeg to solve this problem

upload the source file please, and use file test again, maybe the problem is happened with udp input.

comment:3 Changed 2 months ago by krs_vital

today I managed to record what is obtained at the output (HLS) and the input (UDP) as well as a full report about the behavior of ffmpeg. All of this is in the archive from the link below, a little explain: when there is "Continuity counter error" ffmpeg is stopped at this error message for 10 seconds, then have HLS says that you have exceeded the limit of idle frames, the limit is just set to 10 seconds and then another voznikaet error PES packet size mismatch, then an error timestamp discontinuity 10104000, new offset -37818881300 and so on. At this time, the output HLS sound disappears. Only helps restart ffmpeg.

i made record this file with ffmpeg with report, link here:

I noticed that after 852 of the frame appears an error of this kind:

comment:8 Changed 2 months ago by krs_vital

yes, from file this error is absent!
but if to stream this file to udp with multicat (Shant_Premium.aux is needed for this tool)

/usr/local/bin/multicat -t 10 ./Shant_Premium.ts 239.192.100.100 (it reproduce udp input)

and then launch

ffmpeg -i udp://@239.192.100.100:1234 -c copy ./out.ts

this error appears!!

comment:9 Changed 2 months ago by krs_vital

I analyzed the incoming stream and realized that the problem occurs in cases where the flow disappears(the problem with the satellite signal) and appears again, in some cases ffmpeg cannot correctly decode the audio frame after the onset of flow and after that the sound on HLS output is not restored.

comment:10 Changed 2 months ago by cehoyos

I tested the following:

$ ffmpeg -i udp://@239.192.100.100:1234 -c copy -t 90 out.ts

and in another console

$ multicat -t 10 ./Shant_Premium.ts 239.192.100.100

The output file out.ts plays as good as Shant_Premium.ts with FFplay, I can hear audio for approximately 90 seconds.

Console output:

$ ffmpeg -i udp://@239.192.100.100:1234 -c copy -t 90 out.ts

ok, now try to test hls output instead ts with udp input.

ffmpeg -report -i udp://@239.192.100.100:1234 -c copy -sn -dn -f hls out.m3u8

lets se my changes of ffmpeg.c, it solve problem when signal down more then 10 seconds

this change duration after discontinuity PTS and DTS correcting, now it makes before

check this ffmpeg.c file please

comment:14 Changed 7 weeks ago by krs_vital

after many tests my ffmpeg.c file is wrong, but i found a sulution:

/usr/local/bin/ffmpeg -dts_delta_threshold 120000000 -dts_error_threshold 120000000 -buffer_size 8388608 -pkt_size 1316 -fifo_size 80000 -overrun_nonfatal 1 -copytb 1 -i udp://239.192.3.123:1234 -sn -dn -c copy -hls_allow_cache 0 -hls_ts_options mpegts_flags=+system_b -hls_base_url /ts/Fuel_HD/ -hls_list_size 5 -hls_time 5 -hls_flags delete_segments+omit_endlist -map 0 -ignore_unknown -strict -2 -use_localtime 1 -max_interleave_delta 120000000 -hls_segment_filename /hls/ts/Fuel_HD/stream_%s.ts /hls/pl/Fuel_HD.m3u8

input params:
dts_delta_threshold - 120 sec
dts_error_threshold = 120 sec

output params for muxer:
max_interleave_delta 120 sec

when all of stream scrambling or one of sound or video tracks disapears or scrambling for 10 seconds and more and after then restored (not scrambled or sound or video track in the stream apears again) and if dts_delta_threshold = 10 sec (by default) and muxer option max_interleave_delta = 10 sec (by default) then muxer do force output and this behavior leads to 2 problems:

  1. memory leak of ffmpeg from mux.c
  2. loss or lag in sound

im create a new ticket: https://trac.ffmpeg.org/ticket/6623
