I’ve got an HDHomerun for liveTV configured in jellyfin and am seeing something strange. I don’t know if it’s a bug or if the OTA channel provider is deliberately messing with the tags associated with their signal to force it to stream in low quality.
On most regular HD channels where the image looks good, in the transcoding log I’ll see the following variables:
DisplayTitle - will be something like “720p MPEG2VIDEO SDR” or “1080i MPEG2VIDEO SDR” , matching what the station is broadcasting in.
It’ll also have a valid BitRate, BitDepth, Height, Width, AverageFrameRate, etc.
On one channel (the DFW Fox affiliate) the image quality is awful in Jellyfin (but fine using the HDHomeRun App.) I see several differences with the variables.
DisplayTitle will be “144p MPEG2VIDEO SDR”. The BitRate, BitDepth, Height, Width, fields will all be zero or null.
I’m assuming one of two things
1) Jellyfin doesn’t like the formatting of something and cannot configure ffmpeg appropriately.
2) The TV station is deliberately inserting false data into their stream so certain types of device (IE, not actual televisions) artificially cripple the image quality.
Hoping someone has run into this before and has a solution/workaround.
