  • Synchronization between camera video and inertial sensor data

    14 janvier 2013, par Dima Bobby

    I need to :

    write an Android real-time data logging application employing camera video and polling other sensor (accelerometer, gyro, compass) data at high rates e.g. 50 Hz and writing this information into file. As these data will later be used for navigation, precise synchronization between different data is extremely important.

    What I have done :

    implemented sensor polling in native code, so that less Java execution overhead is employed. Nonetheless, camera encoding is still in Java, for this I tried MediaRecorder and MediaCodec. In both cases data from inertial sensors and camera are not synchronized between each other, there is a varying delay of about 400ms and this is inacceptible. Moreover, I am pretty sure that encoding is HW accelerated. Now, to reach my goal I am considering about going for native implementation of video encoding using either OpenCV or FFMPEG (native code is expected to be more efficient).

    EDIT : I have even tried saving the image uncompressed as pgm file, but this way the image data get really huge in size and the FPS is really low, so we are losing data. I suspect that file writing process is the bottleneck in this case. Is there an efficient way to save raw data to file achieving high FPS ?

    Any hints what I should go for to achieve my goal ? I am using Android Jelly Bean with Asus Transformer TF700 Infinity.

  • lavf : add AV_DISPOSITION flags for WebVTT text track kinds

    lavf : add AV_DISPOSITION flags for WebVTT text track kinds

    There are 4 separate WebVTT text track kinds : subtitles (the default
    
if not otherwise specified), captions, descriptions, and metadata.
    
The WebM muxer needs to know which WebVTT text track kind this is, in
    
order to synthesize the correct track type and codec id.
    

    To allow a demuxer to indicate the text track kind of the input, a new
    
set of AV_DISPOSITION flag values has been added, corresponding to
    
each of the non-default text track kind values.

    Précision : alors que le logo devrait être dans IMG/logo/fichierdulogo il se trouve dans IMG/siteon10.png
    Il manque donc le dossier logo/.
