Hi, I have recently decided to try VLC again for the first time in about six years. The main feature of interest is Replay Gain support, which I already take advantage of for my music library in Winamp, and I also want to use it for my video library. Winamp works with Replay Gain data from MP4 video files, but it's not very good as a video player. VLC is a much better option.
I have been unable to get VLC's Replay Gain feature to work for MP4 video files or MP3 audio files. VLC fails to read Replay Gain metadata from MP4 and MP3, but for some reason it does read this metadata from FLAC files.
For MP4 and MP3 files, using extreme values on the "Replay preamp" setting does nothing to audio volume. This setting only affects audio for which Replay Gain metadata has been retrieved. However, audio volume is affected by changing the "Default replay gain" setting, which only affects audio for files that have no Replay Gain metadata. It's clear that VLC is failing to read the Replay Gain metadata from MP4 and MP3 files.
Also, when I play an MP4 or MP3 file, the Metadata tab of the "Current Media Information" window is completely blank. When I play a FLAC file, the Metadata tab shows various fields, including Replay Gain values. Replay Gain values also appear in the Codec tab.
Every media file I've tried properly show their tags in the General Tab of the information window, including MP3 and MP4 files. It's "advanced" metadata that VLC is failing to read, and this causes the feature I want most to be unusable. Any help with this issue would be appreciated.
