Hello I'm having difficulties to replay recorded audio files in Firefox (same for Chrome). I dare to post this link where described the whole problem: https://stackoverflow.com/questions/53143428/html5-audio-video-tags-partially-not-working-with-camera-voice-recorder-source In general: In my HTML5 app the user can access the video and audio recorder from the mobile device itself. I catch this after recording and show it for replay purposes. The Firefox browser allows me to start the play button but there is no play length nor the audio file will be played. Any hints?
