Sono in grado di riprodurre uno Streaming video con connessione server http in un SurfaceView. E stavo creando ContextMenu per la registrazione del video aggiungendo voci di menu StartRecording e StopRecording. Ma sono in grado di registrare una videocamera video chiamando mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);Come registrare video in streaming?
Qui voglio impostare la sorgente video come sorgente video in streaming. C'è qualche possibilità per farlo?
Ma voglio registrare lo streaming video mentre è in riproduzione. Puoi dirmi come registrare mentre sta suonando?
Si prega di fornire qualsiasi codice di esempio per questo problema?
Il mio codice di esempio riportato di seguito:
