Hello all,
This is my first time posting to this list, so please forgive me if I break
etiquette.
I have a few "problem" WMVs that come through our system from time to time
that I am trying to get resolved. I've tried everything I can think of at
this point, and been all over the internet looking for solutions. We run two
transcodes on the files that come in: one preparing it for the web (flash
streaming media server), another preparing it for mobile (iPhone, Android,
etc). The odd thing is that the mobile works fine, while the web has
problems.
I'm going to list a few things down here now. Hopefully, some of it will
help make sense of what's happening.
1. MediaInfo dump from the offending WMV file
2. Complete web transcode log
3. Complete mobile transcode log
Thank you in advance for any help you may be able to provide. If I can do
anything else to help, please let me know.
James
