Use with the ffmpeg command-line tool Internal hwaccel decoders are enabled via the -hwaccel option. ffmpeg is a whole lot of encoders and decoders and filters in one software package. The image supports Hardware acceleration on x86 pay close attention to the variables for the examples below. Note that it's considered more of a tool to test the DXVA functions in the decoding libraries (so it can be tested without an external player) than an actual useful user feature. The command line used is. Container. 265 by QSV hw-encoder you need instruct ffmpeg to use hw-accelerator 'qsv' by '-hwaccel qsv', apply HEVC hw-encoder by 'c:v hevc_qsv', in addition you need load hevc plugin (see the example command line). Commands running in the shells in 1 and 2, to the left: (a). If you are using the Mesa driver on an AMD device, some MPEG-4 part 2 streams may be supported if you set the environment variable VAAPI_MPEG4_ENABLED to 1, but it's not enabled by default because the implementation is incomplete due to API constraints. To set the language of the first audio stream:avisrunyard@gmail. Example output below. If set to vaapi , it will send the hardware surfaces into the filter chain without copying back to normal memory, so that hardware filters can act on them directly. 264デコーダはベースラインプロファイルのみをサポートしてもよい)。. y4m -c:v hevc_amf -quality quality -usage transcoding -b:v 8M -bufsize 16M -maxrate 12M output. mkv" -s 1920:1080 -aspect 16:9 -vf scale=out_color_matrix=bt2020nc:out_h_chr Another very useful way to use ffmpeg is for hassle-free conversion between different media formats.

For example, the desired 8M bitrate encoded as 98M. •• Add an exclusion for ffmpeg. The nvcuvid resize option can be used when transcoding from one input to one output stream with different resolution (1:1 transcode). I've looked at OS X's VDA acceleration, but it seems as though you need to do some extra work in the application to support the different hwaccels, but I haven't found any nice examples on how to do it. 2.
