Recording with Correct FPS in Android (120FPS CamcorderProfile Not Working) -

-



i'm using following code request phone (lg g5) record using high speed high quality profile, specifies 120fps , 720p.

    camcorderprofile mprofile = camcorderprofile.get(camcorderprofile.quality_high_speed_high);      mmediarecorder.setaudiosource(mediarecorder.audiosource.mic);     mmediarecorder.setvideosource(mediarecorder.videosource.surface);     mmediarecorder.setoutputformat(mediarecorder.outputformat.mpeg_4);     if (mnextvideoabsolutepath == null || mnextvideoabsolutepath.isempty()) {         mnextvideoabsolutepath = getvideofilepath(getactivity());     }     mmediarecorder.setoutputfile(mnextvideoabsolutepath);     mmediarecorder.setvideoencodingbitrate(mprofile.videobitrate);     mmediarecorder.setvideoframerate(mprofile.videoframerate);     mmediarecorder.setvideosize(mprofile.videoframewidth, mprofile.videoframeheight);     mmediarecorder.setvideoencoder(mediarecorder.videoencoder.h264);     mmediarecorder.setaudioencoder(mediarecorder.audioencoder.aac);

unfortunately frames per second specified ignored. video coming out @ around 25fps! can fix this?

thank you!!

on platform, media_profiles.xml defined capability of video/audio encoder. take qc msm8998 example:

   <encoderprofile quality="high" fileformat="mp4" duration="30">   <video codec="h264"          bitrate="42000000"          width="3840"          height="2160"          framerate="30" />    <audio codec="aac"          bitrate="156000"          samplerate="48000"          channels="2" /> </encoderprofile>

i think may cause video around 25fps.

according http://www.theandroidsoul.com/lg-g4-hacks-improve-camera-performance-60-fps-recording/, seems increase fps modify phone's config file possible.

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
