Problem playing subtitles from HDHomerun Recording

[BillOatman 596]

After recording something using the HDHomerun, it plays back fine both video and audio.  

However when selecting a subtitle (this is the only one in the dropdown):

When I select Play I see:

MediaInfo shows:

I have attached debug server and ffmpeg logs.

Hi.  There is a particular format of closed captions that Exoplayer simply doesn't "see" and we have not yet figured out why and how to work around it.

This should only be a problem on some of your channels

Yes we are looking into it. Thanks.

Thanks for the quick response and information. That one station is the only one that comes in on my homerun at the moment (I have it in a terrible location). So I looked for a stream to record not from my homerun.  I tried about 20 different ones, some sports, some news etc.  I played it in Emby and went to turn on CC.  Each stream only showed EIA_608 as an option, and every one got the "Unable to load subtitle" error.  So at least in my case, the bolded above seems to be reversed.

Until you get it sorted out I'll try extracting the subs and get them into a SRT file and see if they play that way.  If I get anywhere I'll post back. I have a friend who wants to use my server but since she is deaf, it is not really possible at the moment (at least live TV or recordings).

Edit:

Using ffmpeg -i option only on the recorded .ts file shows this:
Input #0, mpegts, from 'Wheel of Fortune S40E93.ts':
  Duration: 00:34:59.71, start: 18856.833167, bitrate: 9673 kb/s
  Program 3
  Stream #0:0[0x31]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, top first), 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn
  Stream #0:1[0x34](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, 5.1(side), fltp, 384 kb/s

So ffmpeg sees no subtitles or closed caption either. Yet MedioInfo does.
VLC also does:

If anyone knows a way to extract these as srt file(s) that doesn't involve uploading the video file anywhere, please let me know.

Might work. YMMV

Hi, yes we are looking into the original issue. Thanks.

I am finishing up testing of a app that can be run by Emby after recordings are complete that uses Whisper AI to generate a subtitle SRT file for the recording. Once I am happy with it, I plan on making it open source and provide executables as well.  I'll post in the utilities area on here after that happens.
