PIPE to FFMPEG?

[dromicron]

it is possible to pipe to ffmpeg to make live hls output?

[atuctuc]

yes, i would also appreciate it if it could redirect the output to a unix pipe!!

@nilaoda how to use live pipe options?

@nilaoda how to use live pipe options?

For example:

set RE_LIVE_PIPE_OPTIONS="-c copy -f flv rtmp://your-streaming-server-url/your-stream-key"

N_m3u8DL-RE.exe --live-real-time-merge --live-pipe-mux "http://path/to/a.mpd"

This will change the command line used for mixing streams and output it to the server you specify. You can also output it as HLS segments by set specific value of RE_LIVE_PIPE_OPTIONS.

On Linux, If you only want it to take effect on a specific command line:

RE_LIVE_PIPE_OPTIONS="..." ./N_m3u8DL-RE ...

@nilaoda Very thanks!

[Shporterator]

I noticed that in this mode, temporary files are not deleted after completion. The folder remains
The command looks like this. Maybe I did something wrong?

RE_LIVE_PIPE_OPTIONS="-c copy -f mpegts pipe:1" /home/N_m3u8DL-RE --log-level off --tmp-dir /tmp --no-log --ffmpeg-binary-path /home/ffmpeg --decryption-binary-path /home/mp4decrypt --key 0:0 "$URL" -H "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36" --del-after-done true --mp4-real-time-decryption true --live-keep-segments false --live-real-time-merge true --live-pipe-mux true --thread-count 3 -sv best -sa all

And I also noticed that errors in the image periodically freezes if you use this method. I can't figure out what this is related to yet. I tried different versions of ffmpeg, the result is the same

@Shporterator have you figured this out? noticed this too

[Shporterator]

have you figured this out?

No.
Do you have any problems with the video when using this method?

[liimee]

And I also noticed that errors in the image periodically freezes if you use this method.

what do you mean by periodically freezes? the stream/pipe stops?

[Shporterator]

what do you mean by periodically freezes? the stream/pipe stops?

During the loading of new fragments, the image stops for a few seconds, the sound continues to work normally.

[liimee]

I think that happens to me too... the video fragment loads way slower (pauses for a moment) than the audio

[nilaoda]

You can try set a smaller value for --live-wait-time

[Shporterator]

Problem remains

[nilaoda]

@Shporterator Then there's nothing I can do. 🫠

[Shporterator]

Then there's nothing I can do.

Very sad

[Shporterator]

Then there's nothing I can do.

This problem is absolutely with any streams, which makes this new feature useless:(

Yep i have the same problem, fo now just do this, maybe you do the same as me for now

N_m3u8DL-RE.exe
--save-dir stream
--del-after-done true
--save-name tNoticias
--tmp-dir temp
"url"
--live-real-time-merge true
--live-wait-time 5
--mp4-real-time-decryption true
--live-pipe-mux
-sv best
-sa all
--key xxxxxxxxxx:xxxxxxxxx
--use-system-proxy true
--custom-proxy http://xxx.xxxx.xxx.xxx:3128

FFMPEG

ffmpeg.exe
-re
-i stream/tNoticias.ts
-c copy -f hls
-hls_time 5
-hls_list_size 4
-hls_flags delete_segments
C:/wamp64/www/bin/m3u8/tNoticias.m3u8

Now working grate no jittler or audio loss or stuck, perfect!! thanks!

To me the problem seems to be the output
Vid 1920x1080 | 5499 Kbps | 50 00m38s/00m55s 16/23 Recording 69% 0.00Bps(1) ⣟
Aud 129 Kbps | ita | 2CH 00m38s/00m55s 16/23 Recording 69% 0.00Bps(1) ⣯
Can we suppress easily?

Edited: Yes I confirmed, I changed pipe:1 to pipe:2 I sent the stdout to dev null and finally I resent stderr to stdout and evrything is working!!! Therefore is the contamination of the std out that create the problem

Could you share the full command that you used to make this work?

[alphalneo]

Sure, I am using linux

RE_LIVE_PIPE_OPTIONS="-c copy -f mpegts pipe:2" /MYPATH/N_m3u8DL-RE --log-level off --no-date-info --no-log True THEURLOFYOURSTREAM --del-after-done true --mp4-real-time-decryption true --live-keep-segments false --live-real-time-merge true --live-pipe-mux true --thread-count 3 -sv best -sa all --concurrent-download --save-dir pippo_FOLDER 2>&1 >/dev/null

The output is N_m3u8DL-RE is done on STDERR, I am sending the SDTOUT to a devnull and I am sending the STDERR to STDOUT

[alphalneo]

Waiting for a solution, for now I solved in this way
modify this line
var progress = AnsiConsole.Progress().AutoClear(true);
which you can find in 3 files
with this
var progress = AnsiConsole.Progress().AutoClear(true).AutoRefresh( DownloaderConfig.MyOptions.LogLevel != LogLevel.OFF );

[alphalneo]

Thank you!

@nilaoda is it possible to change the pipe file location (RE_pipe_dc3a37d4-9ef7-482f-975a-e6a6fa6579bf) to another folder instead of /tmp ?

Latest Actions version supported RE_LIVE_PIPE_TMP_DIR environment var.

[JohnTrabusca]

@nilaoda It still creates to the default /tmp after setting the new path per example: /tmp/ramdisk

Not sure if I'm doing something wrong.

[nilaoda]

@JohnTrabusca

RE_LIVE_PIPE_TMP_DIR="/data/my_temp" ./N_m3u8DL-RE xxx

[JohnTrabusca]

After setting and doing a stat to that file (RE_pipe) in the given path in logs, it cannot be found.

Hello. There is such a link mpd...

https://vs12.vcdn.biz/ea7c2a50874e06892616c81fed8764f1_mgg/vod/mpd/b/450_900_1350_1500_2000_5000/u_sid/0/o/176166551/rsid/8a209735-8af0-46f9-afc9-5aae98954316/u_uid/1546846946/u_vod/4/u_device/cms_html5/u_devicekey/_site/u_srvc/2741/te/1760354712/u_did/web_ufUvWAJW4hh3VWBsJtUHNwHAi8JtabBU/wtrmrk/0/manifest.mpd

The program N_m3u8DL-RE 0.2.0 Beta normally downloads temporary video mp4 files 142 pieces (each size 10.0 MB), adds the disputed one 143 piece and the last one has a file size of 1.5 GB. Collect together the mp4 files have a size of - 2.11 GB with a duration of 01:15:38, although it should be 1.39 GB with a duration of 00:49:59 (only the video without sound and subtitles)

Here are the options available on the command line - N_m3u8DL-RE "%mpd%" --check-segments-count:false --save-name "02" --key 7d91116c8f0b95b8db4953f1f26e6aa2:5a4491ef67bc263c0 125c5914322dfba

yt-dlp - this program load normally video size 1.39 GB

There is a problem with this option RE_LIVE_PIPE_TMP_DIR="/tmp/channel", the pipe file keeps being created in the /tmp/ folder and N_m3u8DL-RE looks for that file in /tmp/channel/, that's why it gives an error
/tmp/channel/RE_pipe_f2eee6bf-6068-43aa-b36a-ac8bca0e5677: No such file or directory
