MKVextractGUI: extracted video result in .h264 format instead of .mp4

[shichi00]

Is there any way to extract my MKV videos to its original raw format (.mp4)?

The problem is: I muxed an MP4 video to an MKV. But it became .h264 after demuxing.
I need to get back the original .mp4 file from before it was muxed as an MKV.

Thanks to anyone who can help.

mp4 and mkv are containers that can contain different video and audio streams. .h264 is just the video stream.

You can use yamb or mp4muxer to mux/make a mp4 from .h264 stream (it might work directly from the mkv container also).
