Video 'buffering' and no ffmpeg log - xenoexclusive - 2024-08-16
Hello everyone.
I'm currently having a peculiar issue with a video file I cannot get to the bottom of. One of my files is playing correctly for the first 7 minutes or so, and then alternates between playing and pausing for 5-10 seconds at a time. I would obviously love to upload a log, but for some reason unbeknownst to me no ffmpeg log is being generated. This error is occurring on the Android TV app. This same file plays all the way through on the Android Mobile app (albeit without the ability to seek without a 'source error' and subsequent crash).
I wish I could provide more information than this but I'm lost without a ffmpeg log.
Does this just sound like potentially a somehow corrupted video file? Even though it plays (without seeking) on the mobile app?
Any help would be greatly appreciated.
Kindest regards.

Can you share the main server log via pastebin? If there is no ffmpeg log then it probably isn't transcoding or remuxing.
Also what kind of Android TV device is this? What server version are you running and what version of the ATV client are you running?
RE: Video 'buffering' and no ffmpeg log - xenoexclusive - 2024-08-16
Would you like the main server log in its entirety or purely before and after a playback attempt?
The device is a Sony A95K, latest server version 10.9.9 and latest 0.17.3 for ATV. All other episodes in this series (so far) work, and are the same specifications.

In its entirely. We aren't just searching for a specific problem. The full logs also gives me a general idea of the health of your setup, seemingly unrelated messages may point to the root cause, it also gives me an idea of how things are configured so I'm not bombarding you with questions.
The fact that only one episode is problematic and that the A95K (nice tv) is probably directly playing the file, the file is probably corrupt to some degree. But I'd still like to see the log regardless.
You can try remuxing the file. Sometimes the video and audio is fine, but the container is malformed. So remuxing essentially generates a new container with the same video and audio.
This command is for Linux, but should also work on Windows and Mac (just change the ffmpeg and media path). And it should work regardless if it is a MKV or MP4.
Code: /usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/path/to/your/problem/video.mkv" -map 0 -codec copy newFile.mkv

Alright here we are.
As it's a new day and the log isn't gargantuan, I will just post it directly here. Hope that's okay. I have deleted the file and am reacquiring it now so will attempt to remux once this is complete and get back to you.

RE: Video 'buffering' and no ffmpeg log - TheDreadPirate - 2024-08-16
If you are reacquiring the file, test the new file first.
RE: Video 'buffering' and no ffmpeg log - xenoexclusive - 2024-08-20
I have tested a redownload of the file and the problem still occurs. I have attempted your command:
Code: /usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/path/to/your/problem/video.mkv" -map 0 -codec copy newFile.mkv
This fixes the pausing/buffering but brings the dreaded purple/green tint. Very confusing.
Out of curiosity, I tried changing my bandwidth limits. Setting the bandwidth limit well above the actual limit resulted in no change. Setting a very low limit resulted in a blank screen and a timeout. Just in case this information is pertinent.

Can you show me the media info for the original file?

The quality selector only comes into play when you select a bit rate lower than the video's native bit rate. If you have, for example, a video with a 10Mbps bit rate and you select 15Mbps nothing will happen. If you select 8Mbps that will trigger a transcode since it is lower than the video's native resolution.

Apologies is this doesn't come out right. Am on mobile and can't access PC for a few hours.
In regards to your statement re: bandwidth limits, that's exactly how I thought it works. Which was why I was confused that setting it below the bitrate resulted in no playback at all. But I'll tackle that problem separately.
Edit: once I have access to my machine for better navigation, I'll compare this media info with other episodes in the series (which all work and are from the same group).
RE: Video 'buffering' and no ffmpeg log - TheDreadPirate - 2024-08-20
When you remuxed the file, did you use .mkv or .mp4 on the new file? I think with Dolby Vision 5 it should stay in a MP4 container.
