ffmpeg comes with a tool to re-order the MP4 “atoms” (Seriously don’t ask what are MP4 atoms it’s geek for the sake of geek).
find the file in ffmpeg_src/tools/qt-faststart.c
compile with gcc
1 | gcc qt-faststart.c -o qt-faststart |
And run.
1 | /path/to/qt-faststart /path/to/src_vid.mp4 /path/to/output.mp4 |
NOTE: This only seems to work for h264 encoded videos (libx264).
