BCConvert Files

BCConvert greatly benefits from having FFmpeg.exe in its root folder.
FFmpeg will allow
BCConvert splitter:
-Create avi and mp4
-Decode older cameras audio
-Correct night mode frame rate

BCNetSDK:
-Create _BC_old_aviaud.mp4. _BC_old.mp4 video + _BC_old.avi audio
-Create _BC_old_mp4aud.avi. _BC_old.avi video + _BC_new.mp4 audio

FFmpeg.exe (eg 4.3):
https://github.com/BtbN/FFmpeg-Builds/releases   <<eg ffmpeg-n4.3.1-29-g89daac5fe2-win64-gpl-4.3.zip in bin folder


Get best raw h264 files from VisionNet 1.1.2.28 or similar(eg SwannView Link 2.1.2.27):

http://www.telran.co.il/images/SmartclientForWIN10--20160602.rar


BCConvert requires files in /BCNetSDK/ from clients x.1.2.x to use any BCNetSDK conversion methods:
BCNetSDK.dll
BCP2P_API.dll
hi_VoiceEngine.dll
IOTCAPIs.dll
playctrl.dll
RDTApis.dll

Get newest BCNetSDK dll's from Swannview Link 2.1.2.43 or iNewCam 1.1.2.46(or DvrWebClient.exe from browser interface on Reolink firmware):
Last surviving official links I know are of x.1.2.28:
https://www.dropbox.com/s/6silfyta0zcuy31/SwannView%20Link%20Windows%20v2.1.2.28.exe?dl=1
http://www.telran.co.il/images/SmartclientForWIN10--20160602.rar
2.1.2.27
http://esslsecurity.com/downloads/softwares/smartclient%20windows%20v1.1.2.27.zip

SwannView Link 2.2.2.8 and Reolink 7.2.2.x use BCSDKWrapper.dll and are not supported.

BCConvert.exe -i infile -o outfile

eg:
BCConvert.exe -i test.h264 -o test

BCConvert.exe -i test.h264 -o test -ffmpeginfps 12.5
BCConvert.exe -i test.avi -n -f 25 -d
BCConvert.exe -i test.264 -f 25 -d
BCConvert.exe -i test.264 -oldavi -newmp4

-i infile
If not set: first h264/264 in local folder will be searched for
Full path can be used

-o outfile
If not set: infile filename will be used. outfile extension will be stripped if entered
Full path can be used

-nosplit
Do not split H264 to raw files.

-nosplitclean
Do not delete raw files created by split.

-splith264vid
FFmpeg will use H264 infile as video source instead of raw.video

-splitfps <fps>
FFmpeg input video fps. If not set: Auto detect

-splitext <ext>
FFmpeg will create this file type. Eg "mp4" "avi" "mkv". If not set: mp4


-newmp4
Use BCNetSDK to create "new" mp4.

-oldmp4
Use BCNetSDK to create "old" mp4.

-oldavi
Use BCNetSDK to create "old" avi.


-avifps <fps>
fps is to correct BCNetSDK avi's that export with wrong fps.

-avidisa
Set avi audio to none. Worksaround BCNetSDK creating unplayable files for new cameras, but files will play no audio.


-noffmpeg
Disable all FFmpeg related features.


-l
Create log BCConvert_log.txt

-h
Show help

-v
Show version


If ffmpeg.exe is found in directory it will:
Convert raw h264 video to avi or mp4 (good for old cameras with no audio):
ffmpeg.exe -f h264 -i _BC_raw.video -y -c:v copy _BC_raw.mp4

Convert raw adpcm_ima audio to aac (good for old cameras):
ffmpeg.exe -f g729 -c:a adpcm_ima_oki -i _BC_raw.audio -y _BC_raw.aac
Convert raw h264 video + aac audio to avi or mp4 file:
ffmpeg.exe -f h264 -i _BC_raw.video -i _BC_raw.aac -y -c:v copy -c:a copy -map 0:0 -map 1:0 _BC_raw.mp4

Convert raw h264 video + raw aac audio to avi or mp4 file (good for new cameras):
ffmpeg.exe -f h264 -i _BC_raw.video -i _BC_raw.audio -y -c:v copy -c:a copy -map 0:0 -map 1:0 _BC_raw.mp4


Auto add audio to mp4 file (BCNetSDK - good for old cameras):
ffmpeg.exe -i _BC_old.mp4 -i _BC_old.avi -y -c:v copy -c:a aac -map 0:0 -map 1:1 _BC_old_aviaud.mp4

Auto add audio to avi file (BCNetSDK - good for new cameras):
ffmpeg.exe -i _BC_old.avi -i _BC_new.mp4 -y -c:v copy -c:a copy -map 0:0 -map 1:1 _BC_old_mp4aud.avi
