media_files_src_bin uses same source-id for all videos in a folder

[Y-T-G]

It would be better if media_files_src_bin dynamically changed source_id for each video or image in a folder. It makes it easier to save them as different files using video file sink adapter which saves based on source_id.

Hello, the problem is not related to the source adapter. It does not change source id because it allows processing chunked files as a continuous object.

The problem is related to the sink adapter mostly, but we believe sinks are purpose built. So because the sink receives the information about the source files in meta, it can handle it properly. Just do not forget enable EOS-sending.

Another trivial option is to use a shell script around the source:

ls | while read f
do
  run source source-id=$f
done

@bwsw The video files adapter sink creates a .mov video file with the source-id as the name. So when processing another video from the same folder, it just overwrites the previous video with EOS. So how do I prevent that?

@Y-T-G it may be a bug.

There's a bug: when CHUNK_SIZE=0 the sink adapter creates only one file video.mp4 and overwrite it after each EOS.

@Y-T-G you can set CHUNK_SIZE to a large value and try again. We consider the report as a bug and fix.

@tomskikh let us fix that please.
