T2S breaks video/audio capturing in progress – Politepix /forums/topic/t2s-breaks-videoaudio-capturing-in-progress/feed/ Tue, 23 Apr 2024 15:02:39 +0000 https://bbpress.org/?v=2.6.9 en-US /forums/topic/t2s-breaks-videoaudio-capturing-in-progress/#post-1015633 <![CDATA[T2S breaks video/audio capturing in progress]]> /forums/topic/t2s-breaks-videoaudio-capturing-in-progress/#post-1015633 Fri, 15 Feb 2013 09:13:02 +0000 HarryS Hi,

First of all thanks for providing the OpenEars framework.

I use T2S to inform the user on special events during video recording. This means I have a video / audio capturing session active (AVFoundation) and want to issue some short texts when reaching certain locations. Problem is, every time I issue a message using say:withVoice:, the capturing session is stopped. The error I receive is “Recording Stopped”. Reason I can certainly think of is the Audio devices (actually output) are used / changed while the capturing session uses it as well (actually input) – which in turn makes iOS stop the capturing session.

Any idea on a work around? Does T2S maybe claim more privileges than necessary (particularly Audio input)? Is it possible to disable and audio input / mic access (I do not use speech recognition).

Thanks for your thoughts and insights.

Is T2S referring to OpenEars’ text to speech, or is that another framework you are also using?

It is a FlintController created during app startup, receiving the say:withVoice: message. So for T2S the simplest solution you can think of. I have the latest framework version installed.

TTS is the conventional term (wanted to let you know so if you need to ask questions elsewhere folks will immediately know what it’s about). You’re correct, FliteController is reasserting a PlayAndRecord audio session and you’re right that it only needs playback if you have no use for speech recognition. What you can try is to change the audio session that AudioSessionManager asserts and then recompile the framework and see if it helps. You’ll make the change in AudioSessionManager.m. If you look around line 271 of that file you’ll see a commented-out list of audio session types, and you’ll basically want to do a search and replace for kAudioSessionCategory_PlayAndRecord, replacing it with the other audio session types you want to try as the audio session that FliteController reasserts before its playback. You could also comment out invocations to AudioSessionManager in the framework and see if it just does the right thing without any interaction with the audio session.

I just replaced kAudioSessionCategory_PlayAndRecord by kAudioSessionCategory_AmbientSound – which seems to be the least exclusive setting for TTS – and recompiled the framework. Worked immediately.

Thanks for the fast and qualified support!

I’m sorry, this doesn’t sound like an OpenEars issue. Video playback during TTS isn’t designed to be supported by OpenEars and the programming problem being encountered is with the video and network API — the contribution of the TTS to it sounds like maybe it is blocking a thread you are also using for your other two operations, but there is no way of knowing based on the information being given.
