Description
Hi All!
My original ffmpeg command is very complicated, so I reproduce this bug with a much simplier command, here it is:
ffmpeg -i 720.mp4 -c:a aac -ab 64k -c:v mpeg4 -b:v 1800k -r 25 -g 100 -f hls -hls_time 4 -hls_list_size 5400 -hls_flags +delete_segments+append_list+omit_endlist playlist.m3u8
output:

As you can see the first segment is 4.064 sec long, which is wrong.
Thank you!

Because the audio pts and duration, maybe you can try without audio
comment:4 by , 7 years ago
Thank you!
Yes it is working without audio.
I'm a bit stucked here, because i need the audio. The original sources are two IP cams:
ffmpeg -rtsp_transport tcp -thread_queue_size 512 -i rtsp://X.X.X.X:555 -rtsp_transport tcp -thread_queue_size 512 -i rtsp://X.X.X.X:556 -filter_complex "[0:v]scale=736:552,crop=w=222:h=552:x=288:y=0[outside];[1:v][outside]overlay=shortest=1:x=5:y=5[pip]" -map [pip] -map 1:a -c:a aac -ab 64k -c:v h264_nvenc -cbr 1 -b:v 1800k -maxrate 2000k -r 25 -g 100 -bf 2 -refs 4 -no-scenecut 1 -strict_gop 1 -profile:v high -pixel_format yuv420p -preset default -f hls -hls_time 4 -hls_list_size 5400 -hls_flags +delete_segments+append_list+omit_endlist test.m3u8
I tried to play with setpts, without success
The weird thing is that one of the cams returns this:
Duration: N/A, start: 0.000000, bitrate: N/A
but the other:
Duration: N/A, start: 0.241000, bitrate: N/A
Is it normal?
Can you please suggest something, what I should try to make this work with audio?
THX!
upload your test 720.mp4 please
