[原]开源的视频转换器，支持gpu，绝对好用ffmpeg的GUI==》dmMediaConverter最新版本2.3

dmMediaConverter is a crossplatform FFmpeg frontend (GUI) exposing some of its features. It is intended to be simple and easy to use but also to be able to achieve complex tasks. I have inspired myself from a lot of media converters like Handbrake, WinFF and MkvMergeGui. One feature was lacking from most of them, video stream copy (pass-through), that made me build this.

Main features:

• stream copy (video, audio, subtitle)
• stream conversion - almost any codec into:
• video - h264, h265, vp8, vp9
• audio - aac, mp3, flac, pcm, vorbis, opus
• subtitles - srt, ass, ssa, mov_text, dvdsub
• add multiple streams into one mkv, mp4  or any other container known by ffmpeg that accepts multiple streams (with or without reencoding). Supports multiple video streams in the same file. Also you can reorder stream position.
• stream profiles - create and apply audio and video profiles
• merge files with the same properties - no reencoding. Ex. Files made by a phone or camera.
• merge different kind of files (different codecs, resolution, etc) into one file. It chooses an output with the biggest width of all source files.
• split or trim a file by given time points (no reencoding)
• bulk convert files using stream profiles or manual settings (no filter options for manual)
• job queue - you can add multiple tasks into a job queue
• parallel jobs - you can run multiple jobs in the same time (multithreading)
• audio auto gain detect - it will parse the whole file and find the proper gain value (reencode)
• picture settings - with changes immediately displayed (reencode)
• scaling - change video resolution (use -2 to keep the aspect ratio)
• cropping and padding
• auto crop - detect best crop values for encoder
• rotate picture in 90 degrees increments
• grayscale
• deinterlace
• deshake
• burn subtitles (only text based for now)
• watermark
• manually add FFMpeg video stream filters
• video aspect correction - no reencoding
• write stream tags like language and title, also container title and creation time -  no reencoding
• copy, add or modify any metadata to stream and container.
• multiplatform
