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.

Fixed.

This unfortunately means that many files are impossible to access, will try to fix.

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.

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 :

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.

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.

Audio in the sample you provided will be fixed soon: It contains AAC audio.

I have tried all the audio encodings, It also not right.
