splitting a file with -f segment options causes all per stream metadata to be lost

[Prakash]

Summary of the bug:
when splitting a video using -f segment the resultant output looses all the per stream metadata.
How to reproduce:
ffmpeg -i anyvideo.mp4 -c copy -metadata:s:v rotate=90 output.mp4
ffmpeg -i output.mp4 -c copy -map 0 -f segment output%d.mp4
ffprobe -show_streams -i output0.mp4

the segmented output no longer as the "rotate=90" metadata. it is gone. So if you have videos taken by cell with rotation metadata, it is lost after segmenting.
Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Notice that the rotation metadata is lost after segmenting.

[Michael Niedermayer]

I see a "TAG:rotate=90" in the ffprobe output, if i run the commands here, so i assume this has been fixed

[Carl Eugen Hoyos]

Fixed since FFmpeg 2.4
