[FFmpeg-user] About hls option "hls_init_time" and "hls_time"

[xyzero]

Hi all:
I use the lastest ffmpeg 3.4.2 to transcode a HLS live streaming with the 
command :
"ffmpeg -i /2011/03/17/20110311090142995200.wmv -c:v h264 -flags +cgop -g 25 
-hls_init_time 1 -hls_time 10 -hls_list_size 0 -hls_flags temp_file -b:v 800K 
/hls_tmp/out.m3u8"
and the m3u8 file was written as
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:2
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:1.00,
out0.ts
#EXTINF:1.00,
out1.ts
#EXTINF:1.00,
out2.ts
#EXTINF:1.00,
out3.ts
#EXTINF:1.00,
out4.ts
#EXTINF:1.00,
out5.ts

It seems that "-hls_time 10" has no effect with the option "-hls_init_time" at 
the same time.
Does anyone meet the same problem before?

Thanks and best regards.

[FFmpeg-user] A question about adding delay in a live streaming

[xyzero]

Hi all:
I want to add a 5s delay in a live streaming such as rtmp, and I use ffmpeg 
command as follows
"ffmpeg -re -i rtmp://live.hkstv.hk.lxdns.com/live/hks -muxdelay 5 -c copy 
-f flv rtmp://localhost/rtmp/test"
The result is the delay has no effect.
If I change the command param "-c copy" to "-c:v h264 -c:a aac", then it works 
correctly in 5s delay.
Delay in a live streaming must need transcoding?
If transcoding is unavoidable, how to use min CPU load to add the delay?
Thanks!

[FFmpeg-user] An error in decoding RTMP (h264&aac) live streaming

[xyzero]

Dear Sir / Madam:
I use ffplay to play a RTMP live streaming (url is 
"rtmp://live.hkstv.hk.lxdns.com/live/hks").
After 16819 seconds of receiving, the decoding function returns error, and 
the error info is as follows.
Or it can be easily happened when use "$ ffmpeg -ss 16750 -i 
rtmp://live.hkstv.hk.lxdns.com/live/hks -f null - "command.
I tried ffmpeg version 3.0, 3.1, 3.3, and it has the same problem. I hope 
you can tell me where is wrong or how to slove this problem.
    Best wishes,
xyzero
