Stopping Capture #43

Open samek opened 9 years ago

samek commented 9 years ago

Hi, When trying to capture from DeckLink Quad from all 4 channels at once (4 bmdcapture processes) They all except one stop after couple of minutes.

I get "Stopping Capture" message from the bmdcapture.

I'm using Ubuntu 12.04.4 LTS with 10.3.1 SDK and latest version of bmdcapture.

Is this a known issue ? Is there any way to know what is stopping the capture ?

Possibly you do not have enough cpu/bandwidth.

It looks like it's related to the pipe file / and reading it with ffmpeg. Since it runs (bmdcapture) into /dev/null for quite some time now.

CPU is not a problem since there are 48 cores on the system.

If you use ffmpeg you lose support from me.

Please test with the latest version of avconv and make sure that you aren't maxing out your cpu.

You get the source, free support is given as goodwill (paid support is another option, mind you).

I have no time nor interest to support people using something different from what I use for free.

I'd be glad if you stop telling me what I should or should not do of my spare time.
