2 months ago The high pitched audio is due to ads in the live stream. The twitch ads are spliced into the stream at a different audio sample rate than the stream audio is. This causes issues when ffmpeg tries to copy the audio track over to the post processed file. The only true solution to this is to not have any ads which is accomplished by:
- Using your twitch token (need to be subscribed to the channel or have turbo)
- Use a stream proxy (Admin > Settings).
You have your twitch token populated in Admin > Settings? And you're either subscribed to the channel or have turbo? If so, can you post the full output from the "running streamlink" log from the API container? You will need to enable debug logging with the DEBUG=true environment variable. Be sure to blank out your twitch token, I just need to see the full command.
What the log line looks like:
{"level":"debug","channel":"fl0m","cmd":"https://twitch.tv/fl0m best,best --force-progress --force --twitch-low-latency --twitch-disable-hosting -o /data/temp/44719661531_04bbff4c-61ba-11ef-b1fd-0242ac1a0006-video.mp4","time":"2024-08-23T20:41:45-05:00","message":"running streamlink"}
Another possible fix-you can try updating the "Video Convert FFmpeg Args" in Admin > Settings removing -c:a copy and replacing with -c:a aac. This will re-encode the audio stream. Reportedly this works for some streams, so maybe worth a shot?

I have been using ganymede for a while, first on a weak NAS, then a windows machine because it had more processing power. Got tired of running docker on windows, so yesterday I installed proxmox and fired up ubuntu VM with docker to run my containers..
While moving to the new machine I naturally upgraded to v3.0.1 Started with a new docker compose file, and no config file. Only copied the ganymede database to a local folder, and mounted the vods folder from the nas with smb. Tested archiving a live stream last night, for 30 min, no issues at all!
Today there was a 6.5 hour stream, and in the ganymede player the sound is slightly high pitched and gets out of sync with the video. If i play the same mp4 file with a local video player, the sound seems to stay synced when skipping around, but is still high pitched. Almost seems like its running at x1.1 speed. Streamer sounds like Mickey Mouse.
In the logfiles there is a warning about "Non-Monotonous DTS in Output Stream", suspect this might be the reason for the issues. But I don't know what is causing it, if its related to the new config, OS, virtualization, or the upgrade to 3.0.
Edit: Did some further investigation and a few other streams I archived after the upgrade also has the same error, its just not noticeable when watching the video.
Also noticed that streamlink detected an ad in the start of the stream, the first 10 sec of the vod there is the twitch window with "preparing your stream". Shouldn't be any ads on this channel. Added auth-token during setup. ffmpeg and streamlink arguments are left default: -c:v copy -c:a copy --twitch-low-latency,--twitch-disable-hosting
FFprobe for the vod
