Thanks to a major refactoring of theffmpegcommand-line tool, all the major components of the transcoding pipeline (demuxers, decoders, filters, encodes, muxers) now run in parallel. This should improve throughput and CPU utilization, decrease latency, and open the way to other exciting new fe...
FFmpeg is primarily a command-line application, which means you'll interact with it through the terminal or command prompt. If you're new to the command line, consider reading about thedifferences between GUI and CLIto understand the benefits of each approach. ...

fdkaac (optional, only if you need high efficiency for low bitrates <= 32k, http://wlc.io/2015/06/20/fdk-aac/ - caution: not official!) To check the dependencies, running following commands via command line should show similar output: $ php -v Copyright (c) 1997-2018 The PHP Group...
option on the command line multiple times. Each occurrence is then applied to the next input or output file. Exceptions from this rule are the global options (e.g. verbosity level), which should be specified first. Do not mix input and output files -- first specify all inpu...
PCIe bandwidth might become the bottleneck when using CPU filters. If possible, filters should run on the GPU. Several CUDA filters exist in FFmpeg that can be used as templates to implement your own high-performance CUDA filter. You can always track GPU utilization and memory transfers between...
Note: 4th Generation Intel® Core™ processors and Intel® Xeon® processor E3 v3 family have only one VIDEO metric If running software codecs, CPU load should be high and GPU load should be zero or low in all of these categories. As GPU work is started, especially for mpeg2_qsv...
