Why does my OGG file have silent gaps?
+
Silent gaps almost always mean that the MP4 file had a multi-track audio layout (commentary, alternative languages, surround backchannels) and we selected the wrong stream. Use the advanced "audio stream" option to explicitly choose stream 0, 1, etc., or re-mux all streams to a multi-track OGG container if OGG supports it.

+
MP3 plays universally. AAC / M4A plays on Apple and almost all Android. OGG / Opus needs a recent player on iOS but plays fine in Chrome / Firefox / VLC. The advanced device preset picks the OGG codec most likely to play on your target system.
