How to bulk convert .264 files from camera?

Question

Video

There is a Chinese camera with alik. It writes in some incomprehensible .264 format, which is not played by ANYTHING except native software, and it is also played by PotPlayer by some miracle.
There is a native converter in the kit, but it is not automated in any way, you have to select each file manually, and the camera writes fragments for 15 seconds.
Tried Movavi video converter, AVS video converter, ffmpeg - no use.
Well, I actually attach the sample: https://yadi.sk/d/2Y-hTCTOkbxaqQ
If someone has ideas, I will be grateful.

Answer 1

Sometimes the title of the video does not contain the correct indications about the codec.
ffmpeg can handle this if you tell it which decoder to use.
For your video, for example:
ffmpeg -c h264_cuvid -i A200911_034607_034621.264.mpg result.mkv it
remains only to choose the output format, and it is possible to check whether the audio track is copied
