Help with FFMPEG

[wes93]

Hello to everyone!!! i need some help!!
I have some chinese cameras that use H265 codec for audio and video and i need to use a chinese app to see the video.
The app is really small and inside the folder there are only two DLL for decoding.
did someone help me to add this dll to ffmpeg? also in linux if is possible?
I think i need the HW_H265dec_Win32D.dll
From what i have seen seems that the audio si G711
{"id":101,"enabled":true,"audioInputChannelID":1," codecType":"G.711alaw"}
Thanks a lot
Stefano

Please post a sample clip.

No one is going to blindly load a DLL from some unnamed "Chinese Camera."

[wes93]

Thanks a lot for your reply.
The dll is included in this app: https://support.zositech.com/hc/en-us/articles/115002996247-Ipcamsuite-V1-2-26-8

I don't have understand at what i need to do the video
Thanks a lot
Stefano

Please post a sample clip or at least a MediaInfo report.

Since these are apparently security cameras the files may also be encrypted.

[wes93]

Thanks again for yoru reply.
I don't know if is correct because i don't have media file but a direct stream so i have do this:

[jagabo]

When are you going to post a sample video from your camara?

[wes93]

Jagabo thanks a lot for your reply.
I have seen that my camera have direct stream link, i have adapted the steam.socket.py so i have this two output files.
The g711 is for audio and h265 for video, if i convert with SOX the g711 i have the soud but with noise. i have attached also the file converted is the Wav

[jagabo]

I was able to remux the "dump" file to MKV with ffmpeg:

ffmpeg -y -f:v hevc -i "both.dump" -f:a mulaw -ar 44100 -sample_fmt s16  -i "both.dump" -map 0:v -map 1:a -c copy output.mkv

The video plays properly but the audio does not. That's the best I could do.

[wes93]

Thanks a lot for your reply!!
Do you have some suggestion for the audio?
Regards
Stefano

[jagabo]

The values I got for the audio came from ffprobe:

ffprobe -f:a mulaw both.dump

Input #0, mulaw, from 'both.dump':
  Duration: 00:01:52.68, bitrate: 352 kb/s
    Stream #0:0: Audio: pcm_mulaw, 44100 Hz, 1 channels, s16, 352 kb/s

But I was never able to get anything recognizable on playback. Even if ffmpeg reencoded the audio. I also tried using -f:a alaw and different sample rates.

[wes93]

So the only way is hacking the DLL i think
Really thanks a lot for all your help

[Budman1]

The wav and the g711 ile have the same duration and byte count. Is it possible that is the sound file? Potplayer plays the h265 file ok.

[wes93]

@Budman1
Thanks a lot for your reply and help!!
Yes the G711 is the audio and the WAV is the G711 file converted with Sox, but the problem is that there is some audio noise...
Thanks again
Stefano

or VLC Player.

Unfortunately the camera doesn’t have the RTSP protocol

But thanks a lot for you help and suggestion
