Hello, I'm new to Jellyfin and not very tech savy. I inherited a very cheap NAS that can't transcode properly. Until I can afford to upgrade I've been using it as server for a Jellyfin WebOs client and it works great except when transcoding.
I know image based subtitles need transcoding, so I only allowed "text based" in the config and I make sure I add a external srt file for the content that I want to have subtitles.
The problem is some videos seem to need transcoding and I can't understand why. As I saw in another thread you can see the transcoding reason in the logs, it says "PlayMethod=Transcode, TranscodeReason=VideoCodecNotSupported, AudioCodecNotSupported"
This video needs transcoding:
Video
Title: 1080p H264 SDR
Codec: H264
AVC: No
Profile: High 10
Level: 50
Resolution: 1920x1080
Aspect ratio: 16:9
Interlaced: No
Framerate: 23.976025
Bitrate: 5142 kbps
Bit depth: 10 bit
Video range: SDR
Video range type: SDR
Pixel format: yuv420p10le
Ref frames: 1
NAL: 0
But this one doesn't need it:
Video
Title: 1080p - HEVC - SDR
Codec: HEVC
Profile: Main 10
Level: 120
Resolution: 1920x1080
Aspect ratio: 16:9
Interlaced: No
Framerate: 23.976042
Bitrate: 2742 kbps
Bit depth: 10 bit
Video range: SDR
Video range type: SDR
Colour space: bt709
Colour transfer: bt709
Colour primaries: bt709
Pixel format: yuv420p10le
Ref frames: 1
They look the same to me except for the codec but I own lots of H264 videos and they don't need transcoding.
The audio for the transcoding video is this:
Audio
Title: Japanese - AAC - Stereo - Default
Language: jpn
Codec: AAC
Profile: LC
Layout: stereo
Channels: 2 ch
Bitrate: 316 kbps
Sample rate: 48000 Hz
Default: Yes
Forced: No
External: No
The audio for the non-transcoding video is this:
Audio
Title: Surround - English - AAC - 5.1 - Default
Language: eng
Codec: AAC
Profile: LC
Layout: 5.1
Channels: 6 ch
Bitrate: 320 kbps
Sample rate: 48000 Hz
Default: Yes
Forced: No
External: No
Any idea of what the problem could be?
