Description
Summary of the bug:
Muxing raw H264 content to mkv fails.
How to reproduce:
- Use Sample_7Ch-001.mkv (https://drive.google.com/open?id=17GvV7mOGPaLMaOmJuyZv7AfhRsdrBM-D)
and
ffmpeg -y -i "C:\Users\Selur\Desktop\Sample_7Ch-001.mkv" -map 0:0 -vcodec copy -an -sn -map_metadata -1 -bsf:v h264_mp4toannexb,filter_units=remove_types=6 "E:\Output\Sample_7Ch-001_11_35_02_4510_01.264"
to extract the raw video stream.
This works fine:

Since neither adding '-r 24000/1001' nor additionally adding '-fflags +genpts' and muxing the files using mkvmerge works fine I guess this is either a bug in ffmpeg or I need some help since I don't know how to do this properly.
=> If this is not a bug please tell me how to multiplex raw H.264 to mkv and m2ts.

adding '-f h264' and using:
ffmpeg -y -f h264 -r 24000/1001 -fflags +genpts -i "E:\Output\Sample_7Ch-001_11_35_02_4510_01.264" -vcodec copy -map 0:0 -bsf:v h264_mp4toannexb -vtag avc1 -aspect 177778:100000 -r 24000/1001 "E:\Output\Sample_7Ch.mkv"
doesnt't change a thing:
ffmpeg -y -f h264 -r 24000/1001 -fflags +genpts -i "E:\Output\Sample_7Ch-001_11_35_02_4510_01.264" -vcodec copy -map 0:0 -bsf:v h264_mp4toannexb -vtag avc1 -aspect 177778:100000 -r 24000/1001 "E:\Output\Sample_7Ch.mkv"

Yeah, H.264 timestamp generation is a desideratum for ages.
Btw: There is no need to use the h264_mp4toannexb filter if your input is already an elementary H.264 stream (because that is already Annex B).

Just for completeness and may be it helps with finding and fixing the bug.
Even if I don't feed ffmpeg with raw H.264 and use:
ffmpeg -y -r 24000/1001 -i "E:\Output\Sample_7Ch_videoOnly.mkv" -i "E:\Output\audioOnly.dts" -vcodec copy -acodec copy -map 0:0 -map 1:0 -aspect 177778:100000 -r 24000/1001 "E:\Output\Sample_7Ch-001.mkv"

Shouldn't the .mkv have the time codes needed and shouldn't ffmpeg be able to copy those and if mkv doesn't have the needed time codes, why does ffmpeg need them?
Sample_7Ch_videoOnly.mkv was created with mkvextract using:
mkvextract --ui-language en tracks "C:\Users\Selur\Desktop\Sample_7Ch-001.mkv" 0:"E:\Output\Sample_7Ch_videoOnly.mkv"
Funny thing is if I use FFmpeg for the extraction:
ffmpeg -y -threads 8 -i "C:\Users\Selur\Desktop\Sample_7Ch-001.mkv" -sn -vcodec copy -map_metadata -1 "E:\Output\Sample_7Ch-Sample_7Ch_videoOnly.mkv" -map 0:1 -sn -bsf:a dca_core -acodec copy -map_metadata -1 "E:\Output\audioOnly.dts"
the previous muxing call works.

forget that,
mkvextract --ui-language en tracks "C:\Users\Selur\Desktop\Sample_7Ch-001.mkv" 0:"E:\Output\Sample_7Ch_videoOnly.mkv"
does not create an mkv it creates a H264 raw with .mkv extension :/

For input elementary streams you need to specify format as an input option (-f before the -i)
eg.
-f h264 for AVC streams
