MediaPlayer does not receive stream metadata.

Hi and welcome to devnet,
You should also add the exact version of Qt 6. As Qt 6.5 switched the multimedia backend to ffmpeg.
The OS version would also be useful.

@SGaist Qt6.5, Linux Distribution (Manjaro KDE). ffmpeg can display meta (ICY metadata from command ffmpeg -i %stream%), but MediaPlayer can't display it...

@Driglu4it, sorry for Qt6.5 Linux Neon Developer Edition*
Which release of 6.5 is it ?

Hi,
I can confirm this regression is still present in Qt 6.9.3 on Linux.
I am streaming Internet Radio (ICY/Shoutcast). The underlying FFmpeg backend clearly logs the metadata (StreamTitle), so the data is definitely arriving. However, neither QML (MediaPlayer.metaData) nor C++ (QMediaPlayer::metaData()) exposes this data.I have tried iterating through all available metadata keys (0-20) and requesting the raw "StreamTitle" key explicitly in C++, but it returns empty strings.
FFmpeg Log (Success):
Input #0, aac, from 'https://mp3.ffh.de/ffhchannels/hqeurodance.aac': Metadata: StreamTitle : Jam & Spoon - Angel StreamUrl : 90004532Qt/QML Debug Log (Failure):
qml: --- DEBUGGING METADATA MAPPING --- qml: Direct 'StreamTitle': "" qml: Direct 'icy-name': "" qml: Found data at ID [10]: 00:00:00 (Duration) qml: Found data at ID [12]: AAC (Codec)It seems the FFmpeg backend in Qt Multimedia is parsing the ICY headers but failing to populate the
QMediaMetaDatadictionary for live streams.Has anyone found a workaround using standard Qt APIs, or is the only solution to implement a parallel TCP socket to sniff the headers manually?

@Niclas-Eisenhut hi and welcome to devnet,
Can you also confirme this with the latest 6.10 release ?
