Question

Hi,

I m trying to use a HDMI capture card to get video and audio from HDMI camera output and stream camera feed to AMS.
There is no issue in streaming video from capture card to server. 
But the audio output which capture card is giving out is L-PCM audio format and while streaming this to server using ffmpeg, I m not getting any audio on the server.

Does anyone had such issue earlier with your capture cards and what is the solution to hanlde ALSA capture card devices... ?

Please help me out to get audio from my capture card.

Thanks in advance.
Sam

Hi Vatti,

Thank you for the great question!

Let me explain your issues:
We have already done some tests about ALSA devices before. Which FFmpeg command are you using? Are you sure you added the AAC codec for the audio? 

Please check this link for detail -> https://trac.ffmpeg.org/wiki/Capture/ALSA

Best Regards,
Selim
