I'm reconstructing a video from a large amount of jepg files.
I'd like to keep a trace of original images' timestamp (at least every N minutes) Since there is no mainstream video container format allowing per-frame metadata, I could use a text overlay to keep track of the timestamp.
Timestamp is both "stored" in the filename and in the image exif data, and I would avoid copy/preprocess gigabytes of jpeg with ImageMagick.
Is there a way to combine mencoder mf://@file-list with an hypothetical overlay filter so that the timestamp of each image is encrusted?
(I'm not even sure that the ffmpeg text filter would fit the need)
Either ffmpeg or mplayer solutions welcomed.
