FFMPEGX FINAL CUT PRO MAC OS X
So let's start with the easiest: Mac OS X To get HW acceleration working on OS you should just use the following: avcodec find decoder by name "h264 vda" Note, however that you can accelerate h264 videos only on Mac OS with FFmpeg P N L.

I will update the answer when I get my hands on Windows implementation as well.

How to use hardware acceleration with ffmpeg After some investigation I was able to implement the necessary HW accelerated decoding on OS X VDA and Linux VDPAU. How to use hardware acceleration with ffmpeg /questions/23289157/how-to-use-hardware-acceleration-with-ffmpeg FFmpeg 12.5 Computer hardware 12.3 Codec 11.4 Input/output 7 Encoder 6.6 Nvidia NVENC 4.3 Computing platform 4.2 Nvidia NVDEC 4 CUDA 3.9 Software 3.8 Video card 3.7 Advanced Video Coding 3.6 Hardware acceleration 3.4 Random-access memory 3.1 Transcoding 3.1 Application programming interface 2.9 Central processing unit 2.5 Rendering (computer graphics) 2.5 Data compression 2.3 Graphics processing unit 2.3 FFmpeg M K I offers access to many of these, with varying support. A common feature of many hardware / - decoders to be able to generate output in hardware surfaces suitable for use by other components with discrete graphics cards, this means surfaces in the memory on the card rather than in system memory this is often useful for playback, as no further copying is required before rendering the output, and in some cases it can also be used with encoders supporting hardware C A ? surface input to avoid any copying at all in transcode cases. And zero quality loss from the original RAW data that came out of the JVC.HWAccelIntro – FFmpeg /wiki/HWAccelIntroĪccelIntro FFmpeg Many platforms offer access to dedicated hardware I G E to perform a range of video-related tasks. Result = correct PAL ratio and resolution file with the fields doing what they should, all ready for you to import into your choosen Mac application. Now you can save your file as you wish, I have found MPEG4 on full quality loses zero data (I tested this extensively) but grows the file by around X4, but hey I have a great big hard drive so it does not bother me. > Change the height field (currently 540) to 576.

> In the properties window select the movie track it is the second one down on the top list called MPEG2 Muxed. > When inside Quicktime Pro hit command J (to open the properties window). > Open the file you wish to use in Quicktime Pro. > then drag your clips to your hard drive. So my advice to people using a 'PAL' JVC GZ MC500 with Mac OS X is: I am not sure if JVC intended anything by this odd behaviour or it is simply a foible of the MC500 / MAC interface ? It also occured to me that scaling the clips height from 540 to 576 and keeping the aspect ratio locked resulted in a 768 x 576 clip which is PAL with square pixels.
The scaling in quicktime merely 'reveals' all the information in the file It is worth pointing out that this scaling does not introduce any quality loss as it would appear that the files do actually contain 576 lines of vertical information it is just that they do not show correctly on a Mac. The clips from the JVC GZ MC500 dragged over to my mac (G5 / 10.4.2) appear as 720 x 540 25fps files (when opened in Quicktime Pro / Streamclip etc.)īut interestingly the fields appear screwy when viewd at this original aspect ratio (see image link below), but when stretched to 576 tall (in Quicktime player) the fields clean themselves up and hey presto! the clip appears normal and is the correct size/ratio.
