[FFmpeg-user] HEVC 4k stream dump in mkv container

[gf]

Hi!
I'm trying to dump a "UHD/4k" Astra 19.2° TV demo channel transport stream
from my Sat>IP tuner into an mkv container.
Complete ffprobe output for the stream: http://pastebin.com/DU2q9bfZ
short version:










*Input #0, mpegts, from
'http://192.168.178.20/?src=1&freq=10995&sr=22000&pol=h&m
<http://192.168.178.20/?src=1&freq=10995&sr=22000&pol=h&m>sys=dvbs2&pids=110,120':Duration:
N/A, start: 17414.528133, bitrate: N/AStream #0:0[0x78]: Audio: aac
(HE-AACv2), 48000 Hz, stereo, fltp, 74 kb/sStream #0:1[0x6e]: Video: hevc
(Main 10), yuv420p10le(tv), 3840x2160, 50 fps, 50 tbr, 90k tbn, 50 tbc*

Putting it into an mkv-file with this command *ffmpeg -i
"http://192.168.178.20/?src=1&freq=10995&sr=22
<http://192.168.178.20/?src=1&freq=10995&sr=22>*
*000&pol=h&msys=dvbs2&pids=110,120" -c:v copy -c:a copy -bsf:a
aac_adtstoasc -t 1600 test.mkv*

returns this output: http://pastebin.com/PL4mCtza

Error message at the end:

*Could not write header for output file #0 (incorrect codec parameters ?):
Invalid data found when processing input*

However, if I change the container format to mp4, everything works as
expected.
So I'm not sure what's going on here?

Thanks for reading!
