That’s it! FFmpeg is ready to use!

Standard shell and should work on any decent OS. I’ll describe the steps for Linux, but everything is pretty Of questions on StackOverflow about getting newerįFmpeg releases working on Android. I needed to use FFmpeg concat demuxer, introduced in FFmpeg 1.1. There are a lot of partial and/or out-of-date how-to out there on how to get However,įFmpeg is a C software, meant to be used as an executable, and not officially Software, you have a single name which comes directly to you: FFmpeg. : Persistence will eventually pay off, I confirm and believe it.When you have to manipulate audio or video on Android, being used to open-source After testing, it takes about 1-2s for video transcoding for about 10s, so the processing efficiency is still acceptable. But compared to the time it takes to add a watermark, it's just a drop in the bucket. This operation may be time-consuming, it is recommended to do an asynchronous or sub-thread processing. ts for a segmented synthesis, so I processed this video source during the transcoding process. My processing is because I need a video file ending in. StringBuilder sb = new StringBuilder( "ffmpeg") No encoding is done for the video source, resulting in too large source data. When I searched it, I found that it was a problem with my video source. So the cause of the problem did not lie on the command line. Later I found that the processing speed of this command was still very fast during the process of searching the data. At first I thought it was because ffmpeg had requirements for the performance of the mobile phone. It might take several minutes or even longer, which is unacceptable. Because I modified the underlying video source data in the process of version iteration, the video file generated afterwards was unusually slow when using this command. This code is a normal ffmpeg command to add watermark.append( " -vcodec libx264 -profile:v baseline -preset ultrafast -b:v 3000k -g 25")
