ACVHD .m2ts stream copy

[dizzysaurus]

Hi All,

I'd like to move the video and audio streams from AVCHD .m2ts mpeg2 ts files to mpeg4 .mp4/.m4v containers.

Is there a way to do this without re-encoding the video? I just want to copy the streams!

Thanks!

latest svn of ffmpeg almost gets there:

Any pointers on those errors at the end?

Tried this, but I'm not sure about the outputs:

xporthdmv -h 2007-09-0200000.m2ts 1 1 1

ffmpeg -y -f h264 -r 29.97 -i bits0001.mpv -i bits0001.mpa -vcodec copy -acodec copy test.mp4

AC3 is not allowed in MP4 container therefore I suggest MKV. Use MKVmerge instead of ffmpeg.

[bond]

he said he wants .mp4. in this case you need to reencode the audio into the aac format

Heh, looks like I got moved.

It was pretty easy to copy streams from m2ts -> xport -> mkvmerge. However I found that mkv doesn't seek very well, are there settings to enable faster seeking or indexing?

With .mp4 seeking is near instant (on a recent PC), but with mkv, it seems to take 10 to 40 seconds to seek, depending on how far into the video I go.

How does one enable fast seeking in .mkv? Also, .mp4 will be much more widely supported, correct?

Many Thanks
