I've been using ffdshow since they days of DivX -) as a substitute for codec packs with malware. Always thoroughly test a new build, and don't upgrade unless you want to solve a specific problem. I have noted a few regressions (some fixed by Clsid). Developer Clsid still provides limited support over at Doom9, and has changed/fixed the behavior of the codec at my request a couple of times. However, with current operating systems and data formats it will remain useful. Older revisions also include other encoders from ffmpeg, which however were difficult to understand and configure.įfdshow development has now been discontinued. Includes two lossless encoders for intermediate renders (huffyuv and ffv1). The OSD can be shown on screen (with the frame number or other parameters for reference), but not included in the grabs. ![]() It is possible to capture frames anywhere in the processing chain: as decoded, with subtitles, resized, with a diagnostic OSD. Still frame (screenshot) grabbing functionality, which becomes invaluable when comparing different versions of a video. Built-in subtitle renderer draws captions directly onto the picture, without requiring a special renderer or interaction between separate filters, which sometimes fails due to incompatibilities. Output configuration, such as the color space or number of channels, or post processing, apply to all formats. Unified framework for all the supported formats. Older versions of Windows are supported in earlier revisions, with somewhat reduced functionality. Relatively small size for the number of supported formats make ffdshow a good choice for installation on any Windows computer. Wide choice of post processing options, some which can be activated interactively via a hotkey. And don't use a constant quantizer, use a rate factor instead (CRF): this can spare some bitrate by using slightly coarser quantization where finer is really not necessary to preserve enough quality.Video and audio decoder for DirectShow (media players) and VFW (VirtualDub). If you use a quantizer as low as 15, why do you use the "very slow" preset? You will probably not notice an obvious difference to results of faster presets. ![]() You pay for the speed with a higher bitrate to preserve enough quality. If you use a HEVC codec which works on your GPU, the scope will be smaller, the encoding will be less efficient, despite being possibly faster. ![]() This requires a wide scope, comparing several frames in the past and future around the currently encoded frame. The advantage of x265 is that it is a quite complex video codec which is able to search thoroughly for similarities in the video which can be used to encode efficiently. If anything uses the GPU, it is not x265 but a different HEVC codec.īecause x265 does not use your graphic chipsets, it won't benefit from a system with SLI = two graphic chipsets working in parallel. Again, and again, and again: The x265 implementation of a HEVC video codec uses the CPU only. ![]()
