问题 I am using webrtc for video calling in android. I am simultaneously screen recording after call is connected in sender end. I am getting this error log in sender end. Receiver end voice is not hearing when screen recording is started using MediaRecorder. I think webrtc is not streaming audio to receiver end when media recorder is started using microphone.

问题 MediaRecorder is crashing my app when I set the output file to a custom directory. If I set it to Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC) , it works completely fine. My Code: recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setAudioEncodingBitRate(16*44100); recorder.setAudioSamplingRate

问题 I want to make a recording where, I get multiple audio tracks from different mediaStream objects (some of them, remote). Use the getAudioTracks () method and add them to a mediaStream object using addTrack (). At the moment of passing this last object as a parameter for mediaRecorder I realize that it only records the audio track located in position [0]. That gives me to understand that mediaRecorder is capable of recording a track by type, is there any way to join these tracks into one to

问题 Background : I need to play each webm file individually which are created by MediaRecorder According to Brad’s suggestion, we need to split the data on the cluster element 0x1F43B675 , and prepend everything before the first cluster to a later cluster I have splitted the data on cluster instances, and made a webm file with header(data before first cluster) and splitted data. For this what I am doing inside the ondataavailable of MediaRecorder API, // below statements would be executed from
