hd codecs doesn't work with bless or abattercamera this is mentioned earlier anyway you can create a script file which replaces all the dsp libraries and libgstdsp.so before launching the app and re put the hd codecs again after exiting it but you need to get the old ones uninstall hd-codecs then backup the original ones including libgstdsp.so then reinstall hd-codecs then gather the newly installed libraries to a folder or so and create that script don't forget to point to that script file by modifying the .desktop file just like what i did hope it helps
