Downloaded video is out of sync

[Mrachan]

I am running this command to download some live stream:

./N_m3u8DL-RE https://live4-ott.izzigo.tv/out/u/dash/DE-PELICULA-HD/default.mpd --key 70a3ab1ea3c45dd570da2a660ae5eeda:0a9db0e08d0b737e6 a64ecaed525d4cb -M format=mkv --live-record-limit 02:00:00 --live-real-time-merge --use-shaka-packager --live-pipe-mux

The resulted mkv and ts file have audio out of sync. When looking at the media info, I see video frame rate is 30 fps and audio is 23.438 FPS (2048 SPF).
I also see:
21:41:41.079 INFO : Selected streams:
21:41:41.080 INFO : Vid *CENC 960x540 | 2670 Kbps | video=2670000 | avc1.4D401F | 31 Segments | ~01m02s
21:41:41.080 INFO : Aud *CENC audio_147682_spa=147200 | 147 Kbps | mp4a.40.5 | es | 2CH | 31 Segments | ~01m01s

Can you help me fix that?

Which version are you using right now?

It came to me that when I was recording (downloading) HLS-stream live, the video and the audio didn't match perfectly.
And in the latest v0.1.6-beta the problem I mentioned has been fixed.

Also, try 'not adding' the -M format=mkv command, and just use mp4decrypt instead of shaka and see what's coming out.

I am using N_m3u8DL-RE (Beta version) 20230412

I will try your suggestions and let you know.

Edit:
I still have the audio sync issues.

Why not?

Can you fly?

Can you please refrain from those ridiculous answers? You are saying it is not possible without saying why? And I said in my message I can download the stream, but the audio isn't synced with video. So it is clearly possible.

Again, you are posting a nonsense messages without giving details. I didn't ask to download me that stream. Why are you doing that?

Also, I find out that sometimes the audio is in sync (same command).

So after some digging I noticed that the audio has 2s more than the video, so I just removed them when merging manually.

i suggest not use "--live-pipe-mux" , and use -M format=mp4 , not mkv, and append this "--append-url-params --mp4-real-time-decryption".
