Jellyfin server freezes if playing special file

[plutonictoast]

Here is ffmpeg logs:

top shows cpu usage around 150% intel core 2 duo. Sometimes freezes the whole system.

Oh boy, that's a nightmare with dark mode. Can you upload that log to privatebin.net or pastebin?

Edit: This is just the audio transcoding, which is happening successfully. On a Core 2 Duo, it's not surprising you notice issues. When transcoding, ffmpeg will use all of the available resources at its disposal which is why it's a good idea to have a server be a server. I don't see any errors here at all.

Does playback work?

Does playback work?

Playback for other series works(without encoding). But exactly this series plays for some time and freezes whole server even through media player app(as I've seen without encoding).

I don't see anything special about the file. Could you provide the Jellyfin logs around this playback issue?

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -analyzeduration 200M -probesize 1G -fflags +genpts -i file:"/data/media/tv/Adventure Time (2010)/Season 01/Adventure Time - S01E01.mkv" -map_metadata -1 -map_chapters -1 -threads 0 -map 0:0 -map 0:1 -map -0:s -codec:v:0 copy -bsf:v h264_mp4toannexb -start_at_zero -codec:a:0 libfdk_aac -ac 2 -ab 256000 -copyts -avoid_negative_ts disabled -max_muxing_queue_size 2048 -f hls -max_delay 5000000 -hls_time 6 -hls_segment_type fmp4 -hls_fmp4_init_filename "9389ada2ec79c5936b0c7e0a1fb83da9-1.mp4" -start_number 0 -hls_segment_filename "/config/cache/transcodes/9389ada2ec79c5936b0c7e0a1fb83da9%d.mp4" -hls_playlist_type vod -hls_list_size 0 -y "/config/cache/transcodes/9389ada2ec79c5936b0c7e0a1fb83da9.m3u8"

Video is being copied, seen from -codec:v:0 copy and audio is being transcoded to AAC seen with -codec:a:0 libfdk_aac but there's nothing wonky going on here. The original audio is AC3 (Dolby Digital) so whatever client you're using is telling Jellyfin that AC3 is not a compatible format.

Do you see this same behavior on all the devices you use?

What are the full specs of the server? I imagine if you are using a Core 2 Duo, you also don't have a lot of memory.

What version jellyfin? Was having an issue myself with playing video when audio needed to be transcoded. Recent update fozed that and has been working since.
