H.264, H.265, etc. benchmarks? #65
Description
I think it might be helpful to have benchmarks related to the input video compression standard. I believe it would be helpful for me. I am tempted to just use H.265+ but if I knew dvr-scan processed one minute of H.264 a lot faster than one minute of H.265+ I might use H.264 instead.
Most technologies have pros / cons. H.265 compresses a lot more than H.264. Ditto for H.265+ vs H.265. That’s an advantage. But is it possible dvr-scan is much slower to process a minute of H.265 than a minute of H.264? Are there any tests answering the question?
If not already dvr-scan benchmarks comparing H.264 / H.264+ / H.265 / H.265+, I would suggest something like the following: For each standard, make a typical surveillance video file. Tabulate file size, minutes of video, time for dvr-scan to process file, output avi file size.
I understand each input video file is somewhat different. Different frames per second. Different scene. Different activity. So perhaps no “typical” file. And dvr-scan run time depends on the cpu. But I think a comparison might still be useful, because we don’t care so much about a 10% difference or something like that. Instead, we want a much larger performance difference, such as 100%. The benchmark we are looking for, I believe, is: # of seconds dvr-scan takes to process one minute (or other interval) of video
I may be totally off. I am ready to be corrected. But in general, benchmarking is helpful for many purposes. And especially for this kind of long-running application.
