Hi,<br> Has anyone come into this kind of problem? The stream duration is 75s on PC, and if only play audio or video on ARM platform, the duration is 75s too. However, if play Audio and Video together, the duration is 70s, the audio has additional noise like electrical spark, da da da da. I print all the alsa-lib function
<span style="font-style: italic;">snd_pcm_writei</span> return, no error. If using osssink as audio sink, duration is right. The following are my cmd line:<br><b style=""><span lang="EN-US">Audio
