OGG to MP4 Converter

The tool performs offline transcoding from OGG Vorbis or Opus to an MP4 container. It outputs an MP4 file with an AAC audio track by default and an optional video stream. This is useful when the destination platform mandates MP4 or when you want to create video assets from audio.
\n
How it works conceptually: detect input audio codec and metadata; if a video track is requested, generate a simple generated video stream (color background with waveform) or wrap the audio in an MP4 without a visible video. The encoding settings (audio bitrate, sample rate, channels) are configurable; the duration is preserved.
\n
Who benefits: podcasters, video editors, social media publishers, and QA engineers who need consistent media packaging. Unique value: offline processing, explicit control over codecs and streams, and batch processing while avoiding cloud latency or transfer costs.
\n
Core features: input validation, optional video generation, metadata mapping, error handling, and detailed outputs such as duration, size, and codecs. Use cases include publishing audio as video, replacing platform-only formats, and archiving legacy files.
