Reproduction Steps

Hi, I happened to notice that this if statement doesn't always account for e.g. ~/directory/*.jpg:

    if (mpctx->playlist->num_entries > 1 ||
        mpctx->playing->playlist_path)
        MP_INFO(mpctx, "Playing: %s\n", mpctx->filename);

ffmpeg -i etc/mpv-icon-8bit-128x128.png test.jpg
xxx@Chimera:~/src/mpv$ ./build/mpv --no-config ~/src/mpv/*.jpg
● Image --vid=1 (mjpeg [Baseline] 128x128)
VO: [gpu-next] 128x128 yuv444p
V: 00:00:00 / 00:00:00 (0%)

Works alright with png:

xxx@Chimera:~/src/mpv$ ./build/mpv --no-config ~/src/mpv/etc/*.png
Playing: /home/xxx/src/mpv/etc/mpv-icon-8bit-128x128.png

### Expected Behavior

Ideally it would show Playing: with the filename.

### Actual Behavior

Doesn't show the filename seemingly with just mjpeg.

### Log File

[test.log](https://github.com/user-attachments/files/27247073/test.log)

### Sample Files

<img width="128" height="128" alt="Image" src="https://github.com/user-attachments/assets/6f7283f7-57af-439e-8cdc-fe044aa91435" />

### I carefully read all instruction and confirm that I did the following:

- [x] I tested and confirmed that the issue exists with the [latest release version](https://github.com/mpv-player/mpv/releases/latest) or newer.
- [x] I provided all required information including system and mpv version.
- [x] I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of `--log-file=output.txt`.
- [x] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
- [x] I attached the full, untruncated log file.
- [x] I attached the backtrace in the case of a crash.

Search the source for the shown playlist condition and reproduce the behavior with ./build/mpv --no-config ~/src/mpv/*.jpg, comparing it with the PNG wildcard case. Update the relevant behavior so the MJPEG wildcard invocation prints the filename, then verify both reproductions and any nearby tests.
