The following instructions have been tested on Ubuntu 16.04 LTS 圆4.ġ) Create a local directory (your linaro directory) that you will use to install the linaro cross-compiler (example: /sd1/linaro)Ģ) Download the linaro gcc cross-compiler from this link to your linaro directoryģ) With your linaro directory as the current directory, run the command: To perform the build, you need an Intel-based computer running Linux. This tutorial describes the steps needed to build a static binary for FFmpeg that can run on an ARMv7 Linux platform (typically a NAS or a single-board computer). In order to stream data into a video element, you need to create a MediaSource object, and wait for the sourceopen event to fire.Edit: updated this tutorial for FFmpeg 4.1. Finally, when n completes the remaining files are emitted and the stream completed (closed). In order to stream the output, an interval time polls the file system for the transcoded output, emitting the data as events via subscriber.next. When run, FFmpeg writes files with an incremental index ( 0.mp4, 1.mp4, …) to the mem file-system. The n has a different configuration than the previous example in order to create a segmented output, with suitable transcoder settings.
The above code uses the same FFmpeg.wasm setup as previously, writing the file to be transcoded into the memory file system.
