Open a suitable local sample
Choose a file you are entitled to use and confirm VLC can begin reading it. A local sample avoids mixing account authentication into a first inspection of container and codecs. Keep its identity private if it contains personal material. VideoLAN’s desktop documentation describes checking codec information through the Tools menu; the precise appearance can vary with the Linux package and interface build.
Record the relevant track fields
Open Tools and Codec Information where that menu is present. Note the video and audio track identities and any displayed picture dimensions, rate or channel details relevant to your question. Do not copy only the overall filename extension. A container can hold multiple tracks, so identify the one actually selected when comparing results. A label supplied in the file is useful evidence but is not an independent quality assessment.
Keep source properties separate from output
The information panel concerns the media interpreted by the player. The television’s current HDMI mode is another stage in the chain. A 4K output setting does not establish that the source file contains original 4K detail, and a decoded audio output does not necessarily retain the compressed codec name. Keep the source report beside the display or audio-path report rather than substituting one for the other.
Share a small redacted summary
For a compatibility question, provide the Linux distribution, VLC version/package source and the relevant track fields. Crop private file paths, titles or other identifying metadata if they are unnecessary. If the file fails before information appears, say so; an empty panel does not establish that the file contains no audio or video. Preserve the original file and avoid repeated conversions before the intended target format is understood.
Questions, answered
Is the filename extension enough for a codec question?
No. Inspect the actual tracks where possible. The extension describes a label or container, while the video and audio codecs can require separate compatibility checks.
