SOLVED: Can not play and TrueHD file when transcoding

[raujaku]

Hello,

I have transcoding enabled via QSV and it seems to work until I try to run a file with TrueHD.

According to logs there is an error dealing with anylzeduration and probesize. Following the suggestions here, Ive changed both but it does not seem to make a difference.
I think the error is more of a nusaince error.

Code:

[matroska,webm @ 0x56393b07cf00] Could not find codec parameters for stream 4 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (500000000) and 'probesize' (5000000) options
Input #0, matroska,webm, from 'file:/data/movies/A Bug's Life (1998)/A Bugs Life (1998) [imdb-tt0120623][Remux-2160p][PQ][TrueHD Atmos 7.1][HEVC].mkv':

Beyond that I am at a loss. Any help would be appreciated.

TLDR; to speed up the library scan process, ffprobe is configured to not read an entire file. If the file has so many audio and subtitle tracks that the default probe size doesn't reach those tracks, that will result in this message.

This is a non-issue. The only consequence is that when you click on "Media Info" for the video it won't list all the audio and subtitle tracks that the probe size couldn't reach.

Oh wow, I did not think I would receive a response that fast. I've added my logs to the main post. So it is a nusaince error then. I don't understand why it won't play the video then, keep getting "This client isn't compatible with the media and the server isn't sending a compatible media format." when trying to play.

The codec parameter error is unrelated.

What resolution is your display that you are trying to play on. I'm betting 1080P. If so, the transcode output is 4K.

Code:

Stream #0:0: Video: h264, qsv(tv, bt709, progressive), 3840x2160 [SAR 1:1 DAR 16:9], q=2-31, 114929 kb/s, 23.98 fps, 90k tbn

Depending on the client, you should have an option to set a "maximum transcode resolution".

What client are you trying to play on, btw?

[raujaku]

4k testing on Firefox.

If i try the same file on Apple TV also on 4k display; it just shows a block screen with a red x.

Does your TV support HDR? The output is also HDR10.

Also, Firefox should be able to handle downscaling the video to whatever resolution.

Yes, The TV supports HDR and it will play the file fine if I use any other file codec that is not TrueHD or DTS 7.1 log from running Dolby Digital Codec.
