java - Can you record two MediaRecorder video streams at once? -


we looking @ writing android app , need create 2 copies of video record. each 1 require different settings (dimensions, etc). 1 'high quality' version (1280x720, high bitrate) , 1 'low quality' version (480x360, lower bitrate). both mp4 files.

we have found using mediarecorder record higher quality version , using ffmpeg convert video afterwards lower quality version excruciatingly slow. getting speeds of 6 minutes 22 second video converted!

so possible have 2 instances of mediarecorder @ once stream captured , encoded file on-the-fly, saving need encode after it's completed?

alternatively there other suggestions how can achieve this, or maximise ffmpeg's performance?

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
