H264 video can not read after downloaded with rtmpdum

[kakin]

Hi,
I have a trouble with my downloaded video using rtmpdump command, no video application can read it.
This is my command

rtmpdump.exe -r rtmp://221.132.35.145:38000/live/51/51_1 -o test.flv -v

I attached with my downloaded video.
Can anyone help me please!

What does mediainfo say? Open the flv and check the video and audio codec.

Ps.: recommendation: extract video with flvextract, then multiplex the video with MP4box into a mp4 container.

Dear Selur,
Can you explain me the detail of using mediaInfo, flvextract and MP4box?
I had downloaded them into my PC. Run flvextract I had 2 more file "test.264" and "test.txt", but I don't know how to multiplex the video with MP4box into a mp4 container.
Thanks!

[Selur]

test.264 is the video stream, the txt contains some additional infos about the input file.

mp4box -add "path to the .264 file" "Path to new mp4 file"

should to the muxing using MP4box

about mediainfo, using the command line version of mediainfo:

mediainfo --Full "Path to file"

produces the output I posted above.
