  2. play this wma file on Android，after skill audiobookshelf process
  3. server FFMPEG process is still running

Additional Notes

In this log file, I first used 'Close Player' to stop the playback, and it showed '[FFMPEG] Transcode Killed'. Then, I tried to stop the playback by killing the client process, but it did not show '[FFMPEG] Transcode Killed'.

Not sure if related, but I just I witnessed my homelab server's cooler start making an audible noise, went to check the logs and discovered this was related to audiobookshelf starting some transcoding work out of the blue.

Here are the logs - you can clearly see some interaction with audiobookshelf I had during the morning, before a very random work started around 16:32.

Did my Android app in the background requested something from the server to cause this? 🤔 If so, how can I make Android app stop doing what it was doing? In my case I didn't have that many files to process, so I just waited to this "Check files..." to finish some 10 minutes later.

@gmile commented on GitHub (Jul 20, 2025): Not sure if related, but I just I witnessed my homelab server's cooler start making an audible noise, went to check the logs and discovered this was related to `audiobookshelf` starting some transcoding work out of the blue. Here are the logs - you can clearly see some interaction with audiobookshelf I had during the morning, before a very random work started around `16:32`. <details> ``` Jul 20 09:52:22 nixos audiobookshelf[914]: [2025-07-20 09:52:22.171] INFO: [SocketAuthority] Socket Connected to /socket.io WSQ1E20qOWpyp1DdAAAB Jul 20 09:53:00 nixos audiobookshelf[914]: [2025-07-20 09:53:00.825] INFO: [SocketAuthority] Socket WSQ1E20qOWpyp1DdAAAB disconnected from client "root" after 38654ms (Reason: client namespace disconnect) Jul 20 09:53:11 nixos audiobookshelf[914]: [2025-07-20 09:53:11.858] INFO: Received ping Jul 20 09:53:12 nixos audiobookshelf[914]: [2025-07-20 09:53:12.041] INFO: [SocketAuthority] Socket Connected to /socket.io 859JX0Z40iprkEYKAAAD Jul 20 09:53:19 nixos audiobookshelf[914]: [2025-07-20 09:53:19.339] INFO: [PlaybackSessionManager] startSession: Closing open session "The Selfish Gene" for user "root" (Device: Pixel 8 Pro SDK 36 / v0.9.81-beta) Jul 20 09:53:25 nixos audiobookshelf[914]: [2025-07-20 09:53:25.738] INFO: [PlaybackSessionManager] startSession: Closing open session "The Real Anthony Fauci: Bill Gates, Big Pharma, and the Global War on Democracy and Public Health" for user "root" (Device: Pixel 8 Pro SDK 36 / v0.9.81-beta) Jul 20 09:59:25 nixos audiobookshelf[914]: [2025-07-20 09:59:25.322] INFO: [SocketAuthority] Socket 859JX0Z40iprkEYKAAAD disconnected from client "root" after 373282ms (Reason: ping timeout) Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.353] INFO: [PlaybackSessionManager] startSession: Closing open session "An Elegant Puzzle" for user "root" (Device: Pixel 8 Pro SDK 36 / v0.9.81-beta) Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.360] INFO: [STREAM] START STREAM - Num Segments: 3963 Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.367] INFO: [INFO] FFMPEG transcoding started with command: ffmpeg -seek_timestamp 1 -f concat -safe 0 -i /var/lib/audiobookshelf/metadata/streams/7788263f-10dd-4507-8be8-536fa5ea9eed/files.txt -y -loglevel error -map 0:a -c:a copy -f hls -copyts -avoid_negative_ts make_non_negative -max_delay 5000000 -max_muxing_queue_size 2048 -hls_time 6 -hls_segment_type mpegts -start_number 0 -hls_playlist_type vod -hls_list_size 0 -hls_allow_cache 0 -hls_segment_filename /var/lib/audiobookshelf/metadata/streams/7788263f-10dd-4507-8be8-536fa5ea9eed/output-%d.ts /var/lib/audiobookshelf/metadata/streams/7788263f-10dd-4507-8be8-536fa5ea9eed/final-output.m3u8 Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.367] INFO: Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.765] INFO: [adts @ 0x916d580] Scalable configurations are not allowed in ADTS Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.766] INFO: [out#0/hls @ 0x91537c0] Could not write header (incorrect codec parameters ?): Invalid data found when processing input Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.815] INFO: Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.816] ERROR: Ffmpeg Err "ffmpeg exited with code 183: " Jul 20 16:32:58 nixos audiobookshelf[914]: [2025-07-20 16:32:58.816] INFO: [Stream] Re-attempting stream with AAC encode Jul 20 16:33:08 nixos audiobookshelf[914]: [2025-07-20 16:33:08.837] ERROR: [STREAM] Transcode never closed...

@advplyr commented on GitHub (Jul 20, 2025):

Abs automatically falls back to transcoding the audiobook to an HLS stream when the device cannot direct play the audio file.

In this case the OP was playing a WMA file on android which is not supported so Abs transcodes to HLS

@advplyr I see. Then my issue is not related (or related only mildly). In my case, the primary issue is that something started to happen without me actively using the application (android) or server UI. Feel free to mark my comment as out of topic, I will create a separate discussing for this 🤔
