I have the TV in the title. I would like to play the following file recorded on my mobile phone:

I use the following custom configuration file in addition to the standard Samsung-CD.conf file:

When I try to play the video, the TV returns an Unsupported format error. If I enter mp4 format in the UMS settings to Skip transcoding, it plays without any problem.

Here is my FFMpeg settings:

: UMS-FFMPEG.jpg (166.33 KiB) Viewed 8304 times

I see this line in Log:

Code: Select all

19:33:52 INFO  Process N:\!Programok\Universal Media Server\bin\ffmpeg.exe has a return code of -22! Maybe an error occurred... check the log file

What is missing from the configuration file or what is set wrong? Why does UMS want to encode with ffmpeg if it is a supported format?

Your phone is probably encoding to a higher level than your TV can decode.
That video is using [email protected] but as your TV is very old it might only be able to do 4.1

There is an option you set in the conf so higher levels are transcoded instead, but the default is 4.1 anyway.

Code: Select all

# The maximum H.264 level supported by the renderer.
# Default: 4.1
H264LevelLimit =

As you are getting an error message form FFmpeg something else could be wrong but I will need to see the logs to see what it is. See the section in red above.

The log file is here for ffmpeg error:

ums_dbg_2025-01-04-21-52.zip: (92.94 KiB) Downloaded 658 times

The solution was to increase the Level. I added this line to the custom config file and the video starts:

Code: Select all

H264LevelLimit = 5.1

It may have been added in a firmware update, although I couldn't find any official info about it, but the video works.

So I can now play the mp4 in question, but those videos that need to be transcoded (such as vp9 videos) may still have problems.

And here is VP9 log too (UMS not encoded over the TV):

There is an error about a colour range in the first video and an invalid argument.

Code: Select all

net.pms.io.OutputTextLogger   Stream #0:1[0x2](eng): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, reserved/reserved/smpte170m, progressive), 1920x1080, 16996 kb/s, 30.03 fps, 30 tbr, 90k tbn (default)

net.pms.io.OutputTextLogger [vf#0:0 @ 0000024f582e0500] Terminating thread with return code -22 (Invalid argument)

But don't know what is causing it.

That second video is transcoding as the resolution is too big for the TV so it is being re-scaled, but I think this is not working right as I have seen similar problems before with the filter_complex argument that does that scaling but don't know enough on how to fix.

Code: Select all

net.pms.io.ProcessWrapperImpl Starting "N:\!Programok\Universal Media Server\bin\ffmpeg.exe" -y -loglevel info -hwaccel cuda -threads 1 -i "H:\!Képeink2\kiki2\Zsu Honor 6\TOLVAI RENI-20250104-DEZ2Qkti6fD-Video by tolvaireni-00001.mp4" -filter_complex [0:v]scale=iw*min(1920/iw\,1080/ih):ih*min(1920/iw\,1080/ih),[0:v]pad=ceil(iw/4)*4:ceil(ih/4)*4:(ow-iw)/2:(oh-ih)/2 -threads 16 -bufsize 1835k -maxrate 24000k -g 25 -qmin 2 -qmax 5 -ab 448k -ar 48000 -c:a ac3 -c:v mpeg2video -f vob \\.\pipe\ffmpegvideo_129_1736024827797

Looks like the width and height values are swapped unless the video has been rotated.

Code: Select all

net.pms.configuration.RendererConfiguration Resolution 1080x1920 is too high for this renderer, which supports up to 1920x1080

I don't see an error with FFmpeg with this one but the connection is reset by the TV so it does not like something.

Code: Select all

net.pms.network.HttpServletHelper Sending stream with premature end: 131072 bytes. Reason: Connection reset by peer

Looking at your UMS.conf it still has old settings that have been moved, changed or not used anymore so must have been using UMS for a long time.
Might be worth doing a clean install and keep everything at defaults to see if transcoding will work properly, and if it does you can start restoring them to what you had them and see if anything breaks. Make a backup of "C:\ProgramData\UMS" just incase but would be better to do the settings by hand. This will also backup your custom conf for the TV.

I just did a clean install and only included the folder where the mobile videos are. I get the same ffmpeg -22 error, I attach the log.

I don't see an error with FFmpeg with this one but the connection is reset by the TV so it does not like something.

How can I set in the TV config file to not send the larger sizes and to encode the largest side to the highest resolution height or width of the TV?

Posted: **Mon Jan 13, 2025 6:27 pm**

MaxVideoWidth and MaxVideoHeight set the supported size of the video, any higher will need to be transcoded to be scaled down to fit.
The default value will be correct so you don't need to set them for this TV.

Code: Select all

# The maximum width and height supported by the renderer. 0 means unlimited.
# Both must be 0, or both must be higher than 0.
# Defaults: 1920 and 1080
MaxVideoWidth = 
MaxVideoHeight =

I compared the transcoding command in this one to the one I posted previously and it is mostly the same, the only difference is using the GPU and scaling but that was not the cause of the previous problem so I think this was right.

I think something must be wrong with the FFmpeg command arguments if it is still giving that error. Maybe some other setting would fix it.

I'll make an issue on Github so the devs can have a look.

Hmm it looks like there are at least 2 problems here.

The H.264 level support change will be merged in the next version of UMS.

But FFmpeg seems to have introduced a problem in v7 with color space defaults https://fftrac-bg.ffmpeg.org/ticket/11020
So that is up to them to fix
