Hello I'm using google's grafika library to create a custom camera app and so far I managed to do everything I want except adding audio to the videos. I searched all over the internet for a similar example but I couldn't find answer to my problem. I tried adding another mediaCodec for the audio, one more CircularEncoderBuffer for the audio too and also adding 2 more parameters to the EncoderThread for the audio mediaCodec and the audio buffer to no avail. When I attempt to start recording I receive a dozen frames and the buffers drain them but afterwards the app freezes with no error and I can't go back to the previous screen or exit the preview by any means.
Has anyone tried adding audio to the continuous capture before ? Do I need another thread for the audio mediaCodec and if so how do I mux the video and audio afterwards ? Do I need a second CircularEncoderBuffer or I should somehow use only 1 to store both audio and video ?
I'm not sure what part of my code will be useful for you guys so I won't add any for now, but if you tell me what you need I will immediately update my question with code sample.
