In the "Even More Information" view from MediaInfo.DLL, this is reported as the overall bit rate. The only bitrate ffProbe's reports is 533294 (without specifying whether this is supposed to be audio, video, combined, or something else). In this case, the audio bit rate matches the one reported in the File Properties. However, MediaInfo.DLL reports a video bit rate of 439316 bps and an audio bit rate of 64000 bps. This video bit rate seems to coincide with the Video Data rate of 0kbs reported for the file on the Details tab of the Properties window for the file. Is there a reliable way to determine whether the BPS from MediaInfo.DLL is actually meaningful and correct?Ĭ) For one WEBM file, ffProbe shows a video bit rate of 0 as well as an audio bit rate of 0. (In the case of this file, ffProbe reports a bit rate of 9200, compared to 0, as reported by MediInfo.DLL). Another (AMR) file has a similar thing, where MediaInfo.DLL reports a BitDepth of 14. So I'm wondering if maybe MediaInfo.DLL is just seeing the WMA format and blindly assuming 16. I think that probably ffProbe is correct because the Audio codec is wmav2, which apparently uses a very low quality lossy compression that probably makes bit depth meaningless. My understanding is that BPS and bit depth are just two different names for the same thing, but ffProbe is unable to determine a BitDepth. Any thoughts on whether the slight discrepancies between ffprobe's output and MediaInfo.DLL's output are significant, or how to evaluate which one is more accurate?ī) For one WMV file, MediaInfo.DLL reports a Bits Per Sample of 16. Observations and questions:Ī) Most of the differences were small variations in the lesser significant digits of various numeric values (bit rate, duration, frames per second), but I had no way to determine which one was actually more accurate. Usually commercial software or games are produced for sale or to serve a commercial purpose.I wrote some logic to compare information from ffprobe vs. Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited. In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces. In some cases, ads may be show to the users. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. Open Source software is software with source code that anyone can inspect, modify or enhance. Freeware products can be used free of charge for both personal and professional (commercial use). Freeware programs can be downloaded used free of charge and without any time limitations.
