mux multi mkv to mp4

[DKhanh]

I need to mux a lot of mkv (h264/acc) files to mp4 (just re-muxing).
I tried many tool such as yamb, mp4muxer, ... but they dont support on multiple files, while ffmpeg is not stable (usually it throw error for particular mkv); mp4creator and mp4box only accept raw format as input (so need to extract mkv first,--> waste time)

so anybody know a tool have ability to mux directly to mp4, and support on multi files?

Maybe something like mkv/avi to mp4, https://www.videohelp.com/tools/mkv-avi-to-mp4

yes, it's just something, not what i want.

mkv/avi to mp4 base on mp4box, mkvextract, beSweet, eac3to, mediainfo are used

it doesnt mux directly, it extract mkv then remux it, take two times to do 1 job. It also doesnt support multi files

ffmpeg or mencoder are your only solutions then.

I said that ffmpeg is not stable, I had run command

ffmpeg -i "input.mkv" -vcodec copy -acodec copy "res.mp4"

and it throw an error

[mp4 @ 03364700] Application provided invalid, non monotonically increasing dts to muxer in stream 0: -2 >= -2
av_interleaved_write_frame(): Invalid argument

And mencoder is not also better, I got the problem like this
