Hello!
I'm not sure wheter it was discussed somewhere, but didn't find anything. I was playing with movie recording today and I've noticed that while movie is being recorded the temporary file is created in the appropriate directory (A/DCIM/current_photos_dir). It is called MVI_XXXX.TMP.
I was wonder, what kind of data are stored there, and it seems to be simmilar to MOV QuickTime file but without a header. It contains no "mvhd" strings. I was not playing much with hexeditor.
Since I was thinking about extracting sound data from there I opened this file with an Audacity (an open source sound editor) as a raw audio data. And it was (just like MOV file) a movie sound alternating with nois (video data?).
I'm thinking now, whether we could read this files on the fly during the video recording and add a volume meter to the OSD?
We could also modify this file on the fly, but I'm not sure, whether camera would allow to open this file, while it is already opened. I didn't do this yet, did anyone?
PS. Does anybody know, where in memory could I search for sound data?
