Windows 7 64bit on i7 HP DV7
Demux a MP4 file into .h264 and .aac files. (the default)
Converted .aac file to .MP3 format by ffmpeg. (MP3Gain works with MP3 not aac)
Normalized .MP3 file by MP3Gain. (Sound track too loud in original MP4 file.)
Mux the same files back.
Play time prolonged by nearly 1 whole minute, making the subtitle and vocal out of sync.
Checked the play time in .h264 and .aac/MP3 are matching to the original MP4 file play time.
The problem obvious is in the muxing process. Abandoned. Looking for other more productive programs. |
