Comment (by pbennett):
I have some problems with this patch #13171.
* It is already possible to change the number of output buffers with the
setting !OmxVideoBuffers (e.g. -O !OmxVideoBuffers=15 on the command
line). We could if needed add it to the setup GUI or change the default
value to 15.
* The criteria for failure and fallback. The only time the !CreateBuffers
fails is if the malloc fails, and that will likely never happen. If it
causes low memory, the system will instead begin swapping, and then
performance will slow to a crawl. I do not think that fallback logic is
useful.
I have tried with -O !OmxVideoBuffers=15 and have not been able to see any
difference in performance.
