    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I am trying to encoding 1280x720 H264 at 14mbps.&lt;/P&gt;&lt;P&gt;Encoding content is write to SATA disk.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Normally encoding is going without any issue but When we do mouse movement and audio stutters during this time.&lt;/P&gt;&lt;P&gt;If we do encoding at lower 8 mbps , encoding content has a perfect audio. no effects on mouse movement. Everything works fine.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;What could be the reason behind this issue?&lt;/P&gt;&lt;P&gt;Does VPU load effect on another peripherals?&lt;/P&gt;&lt;P&gt;Or Higher data write rate to SATA disc creates the issue?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Check following debug message.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;ERROR: ENCODING SLOW &lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;W/AudioFlinger( 2375): RecordThread: buffer overflow&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;ERROR: ENCODING SLOW &lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 21 ms total 218 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 1852&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 40 ms total 258 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 3528&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 51 ms total 309 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 4498&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 10 ms total 319 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 882&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;I/FslCameraHAL( 2375): no buffer in v4l2, continue&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 31 ms total 350 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 2734&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 10 ms total 360 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 882&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 70 ms total 430 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 6174&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 37 ms total 467 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 3262&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): LEVEL: 1 FUNCTION: ProcessDataBuffer LINE: 293&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioSource::ProcessDataBuffer, GetOneFrameFromDevice Failed&lt;/P&gt;&lt;P&gt;W/audio_hw_primary( 2375): in_get_input_frames_lost 25 ms total 492 ms&lt;/P&gt;&lt;P&gt;I/OMXPlayer( 2375): AudioRecord lost bytes: 2204&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks&lt;/P&gt;&lt;P&gt;Saurabh&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
