(SCS11.7.0) Video playback woes

[adamhawes]

Hi,

SCS 11.7.0-x64 on Windows 8.1. The Windows install is pretty-much vanilla with all current updates installed. I installed SCS with LAV filters and they appear to be installed correctly. Video driver and renderer are left at the default settings (TVG/auto). Video file is MP4 - H.264 (640x480) with AAC audio, but LAV filters seem to support that combination.

I have a show with a 4x4 USB audio device connected. I have a device map for ASIO (BASS) that works great for all my audio-only cues. Video cues do not map to the USB device though. Their sound is rendered to the headphone socket on my laptop. In a pinch I could feed this to the mixer too but that's a bit of a hack that I'd rather avoid - the headphone output on my laptop is quite noisy. There are no options on the video cue to route to the external device. My device options are "Default" and "Mute". I guess I could extract the audio separately, run it in parallel and mute the video. That will probably create some lip-sync issues though.

The video also renders full screen even though I have asked to scale it to 50%.

Tech starts during the week, show opens in a week. Any hints would be hugely appreciated.

I've emailed you details of a new version that I hope will fix the video size issue. Unfortunately, all the video playback libraries I've tried (including TVG) only support DirectSound, not ASIO.

Hi Mike,

Thanks for the reply. I'll test out the links you emailed me and report back. I have DirectSound drivers for my interface but they only showed 2 channels on my desk system (Windows 7). It might be OK on my laptop. This is OK for the current show so I'll give it a go and see how it works.

Thanks,
A

Yes, some audio interfaces that primarily support ASIO just support 2 channels of DirectSound.

Hi Mike,

The test binaries fix my scaling issue and also the audio issue using ASIO. I was all set to select DirectSound but when I tested the video to see if it has scaled I got audio out my USB interface without making any changes.

Looks like I'm a happy camper.

Thanks for the quick turnaround.

I'm having the same scaling issues. Can you send me the fix you sent the OP?
