Hi Karen, find comments inline.

Placing the archive operation before all distribution operations will result in _no_ distributed track getting archived. Only source material will be put in the archive. That's probably not what you want. > Is that the same as omitted distributed source-tag in the archive operation's > source-tags configuration? > > ref: http://opencast.jira.com/wiki/display/MH/The+Episode+Service > <operation id="archive" > fail-on-error="true" > exception-handler-workflow="error" > description="Archived"> > <configurations> > <configuration key="source-tags">engage,-publish</configuration> > </configurations> > </operation> Yes. > If information about distributed media is omitted from Archive, can media > still be retracted from distribution channels? No because then the retraction workflow operation handlers do not know that something got distributed. > MH-9237, "Episode Service fails making archive of media package after > distribution to YouTube" http://opencast.jira.com/browse/MH-9237 > has a nearly identical stack trace to > MH-9172, "archive operation fails with null pointer exception after streaming > distribution" http://opencast.jira.com/browse/MH-9172 > We thought MH-9172 was because the stream media is RTMP. Is it possible that > this was because the RTMP link did not end with a file extension? MH-9237: YouTube generates URLs without a "file extension". Currently the MediaInspectionService cannot deal with this. MH-9172: Your first guess is correct. Streaming media cannot be downloaded so archiving fails.
