  4. I want to watch/preview video with multichannel sound (1080p60/ac3,6ch,48khz) from a set-top box.
    It should have almost zero delay on screen preview. Is this possible with this card and software like potplayer?
    Thanks, xxxxx

    sorry for the delay..
    if you have a Fast SSD harddisk and pc gen6 intel like i do (or fast pc) yes
    the important thing is the speed of your SSd write
    i record with no delay a setup box tv 1080p60/ac3,6ch,48khz with no problem
    if you use my tool and capture the sound at ac3,6ch and want to edit your video after, to cut some scene you will need
    the codec ac3filter_2_5b
    dowload here h+tp://www.ac3filter.net/wiki/Download_AC3Filter


    or you can download the software from magewell this software work with the chinese version but record sound is not 6ch 44khz
    "USB Capture Utility V2"

  6. I have bought one (AH234), it does not capture ac3. I don ´t know why? What preview software are you using? What filters are you using? Have you made special settings to hear ac3? Or do you hear 5.1 channel pcm and not compressed ac3 via your set-top box? Thx xxxxx

    does your set up box do 6 channel?

    check your recording with this sofware -> h+tps://mediaarea.net/de/MediaInfo
    here the result of my capture test


    remember i dont do piracy only personal use...

  9. fixed qp can be faster (i know plenty of people will argue with this but by fixing qp some time can be saved on crf decision), i would add NVenc and QuickVideo support and also i would AVC Intra profile to GUI.

    qp is quantization factor - fixed qp will quantize frames with same qp (technically if PB is allowed qp for I will be lower than for P and B will be higher by default) - it should speed up encoding as encoder will not calculate what kind of qp should be used to deliver desired quality i.e. crf. (technically crf takes into consideration not only quantization but also other factors like for example framerate, if you wish to save some bitrate you can set different qp for P and B frames
    --ipratio <float> QP factor between I and P [1.40] --pbratio <float> QP factor between P and B [1.30]

  12. My set-top box does ac3,6ch,48khz. If I use this settings I get no sound at all while previewing the video stream I use Potplayer or MediaPlayer Classic for viewing the video.

    do you have win 7 or win 10?
    have you tested with another pc?

    try this command to check your device in a batch file or dos window ->

    ffmpeg -list_devices true -f dshow -i dummy

    do you see= Digital Audio Interface (USB3.0 Capture Audio)

    ffmpeg -f dshow -list_options true -i audio="Digital Audio Interface (USB3.0 Capture Audio)"

    what do you see here?


    try to play with this setting for your device
    ffmpeg -y -f dshow -i audio="Digital Audio Interface (USB3.0 Capture Audio)" -acodec ac3 -ac 6 -ar 48000 -ab 1200k audio.mp3
    ffmpeg -y -f dshow -i audio="Digital Audio Interface (USB3.0 Capture Audio)" -strict -2 -acodec dca -ac 2 -ab 1200k audio.mp3


    when i change this device in usb (i have 4 port) the name change make sure you select the right one in capture audio name

    "Digital Audio Interface (USB3.0 Capture Audio)"
    "Digital Audio Interface (1- USB3.0 Capture Audio)"
    "Digital Audio Interface (2- USB3.0 Capture Audio)"
    "Digital Audio Interface (3- USB3.0 Capture Audio)"

    So the audio is there. I can hear it, too. The Chinese card doesn´t recognize it?
    Do you have a firmware patch or something like that?

    this command will capture 5 channel from your device and save it to wav separately, check after to see if your ear sound

    ffmpeg -y -f dshow -rtbufsize 2048M -video_size 1280x720 -pix_fmt yuyv422 -framerate 59 -i video="USB3.0 Capture Video":audio="Digital Audio Interface (USB3.0 Capture Audio)" -acodec ac3 -filter_complex "channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR]" -map "[FL]" front_left.wav -map "[FR]" front_right.wav -map "[FC]" front_center.wav -map "[LFE]" lfe.wav -map "[BL]" back_left.wav -map "[BR]" br.wav

    do you have voice only in front_left.wav and front_right.wav that mean 2 channel stereo

    do you have sound in the other 3 other wav

    i dont know how to upmix with front_left.wav and front_right.wav into the 3 other channel front_center.wav back_left.wav lfe.wav

    can ffmpeg do 2 channel up-mixing in 5 channel???

    4stereo.zip indeed no sound!

    my tv box in the setting i can chose

    -option 1 is 2 speaker out
    -option 2 is multichanel

    you need to tell your tv box setting audio what type of audio out you want....

    i select multichanel out, my tv not support 6 chanel i ear no sound but plug the device in computer and record...


    have you try this simple program easy to use! http://www.magewell.com/files/CaptureExpress_2806.zip

    do you record the sound with this application??

    Do you have HDMI 2.0b cable?

    if not maybe your device version does not crack your sound hdmi, you will need a "hdmi hdcp crack" but it crack digital to analog signal

    on aliexpress find "HDMI2HDMI" price $7 to 15$ try to buy the latest

  20. Hi my setup is working fine, I´ve got a 1x8 HDMI Splitter installed. I also changed the settings from the set-top box to multichannel layout before recording.
    If I hear the sound with the also installed Hauppauge Collosus 2 I can hear/record a multichannel sound. So the A/V signal is clean.
    The HDV-UH60 can´t record the same A/V source from the splitter which the Collossus does. The multichannel audio is broken, I think there is maybe a firmware fix out there for the HDV-UH60 to improve the recording abilities. If I use the above mentioned CaptureExpress tool with pre-selected multichannel input I can´t record/hear sound. (only stereo sound is fine)
    Below is the A/V tag from Potplayer, the audio stream is indicated as stereo 2 which wasn´t right. (it was multi-channel)
    Perhaps you know where to find a new firmware for my device?
    Thanks Michael

    you may try this!
    http://www.magewell.com/files/CaptureExpress.zip
    capture video and 2 channel

    in the same time use this ->http://www.magewell.com/files/MWCaptureSDK.zip
    XID_MultiAudioCapture.exe allowed me to capture 5.1 audio only no video

    you will need to merge those 2 file mkvtoolnix and create a mkv set audio 5.1 default

    Hello codebox, are you maybe still around here? Looks like both links are dead (first one downloads always broken content & second is dead), could you maybe reupload this tool?

    Thanks, tested also CaptureExpress, indeed a nice tool, but failed for multichannel audio
    I've also tried a lot of different ffmpeg commands, but still no joy.

    When grabber is connected, device is unable to detect Dolby support, so I had to connect an additional EDID updater inbetween to cheat the device.

    So probably it's the latest chance to do an attempt with your tool. If you could re-upload it, I'll be very grateful

    I've also asked producer, but for now no reply.

    I think that it might be possible, that device is even a direct Magewell clone, but with different firmware. For example MultiAudioCapture.exe (and most of new tools for Magewell) are unable to recognize this device at all.

    Maybe reflashing of firmware could change this, but no tools for that & no original firmware to be able to roll back if that will fail...

    It seems that getting multichannel audio with grabbers is still not a very popular topic...
