Description
User sabkaraja uploaded a Hikvision recording for which H.264 video can be decoded with FFmpeg, audio fails. May be G.728, I was unable to find a modern, working decoder to test.
Bitrate is 16kb/s, packet size is 80 bytes.

You don't see a "Big Story" logo when playing the file?
No, I can't play it with QuickTime
I don't think the file was meant to be played with QuickTime but in any case this is the FFmpeg bug tracker, I believe you have to report QT issues somewhere else.
I tested FFmpeg and MPlayer, both show the video successfully.

This is my isuue:
I use Hikvison to record video, but when I use the command line:
d:\wnmp\videoTools\ffmpeg.exe -i 20150327215559_ch01.mp4 -vcodec copy -acodec copy ab.mp4
the it output :
missing header.....

Please upload your sample to http://www.datafilehost.com/ or read https://ffmpeg.org/bugreports.html (there is no filesize limit).
You will easily find my email address either in git, the FFmpeg homepage or using Google but if you send me the sample, I will upload it.

Thank you for the sample. What is the name of your camera?

Could you provide samples with different audio codecs?
Reading the manual, there should be an Audio Settings Interface when you select "Configuration" >
"Video / Audio" > "Audio" in the camera interface. Could you provide samples for all audio encodings (should be "G.711 ulaw", "G.711alaw", "G.726" and "MP2L2")?
Audio in the sample you provided will be fixed soon: It contains AAC audio.

Sorry, I just have G.711alaw now, the sample is here: http://www.datafilehost.com/d/8c02ecd3

The samples you uploaded should be fixed since f8413f74a1847db161a3443b1740b2659cd48753 and 036079ce34311547be5940c5d856db5498fae029
More unsupported samples, particularly G.726 are very welcome!
