![]() ![]() It has no process for checking the answers or analyzing them and I'd rather not ask it how confident it is because that's just not what I care about. We can check our answers, we can spit out bullshit like it does but then take the time to check them. I omitted the n,v, and a values in the concat filter, as they are by default 2,1, and 0 respectively.Īnother way to visualize this filter in an imperative style would look like this: filter_complex "concat eq=brightness=0.3" ![]() The correct way to write the filter, if the intended use is to discard the audio, would be: That being said, this filter isn't correct, as the value is never used or mapped, so the filter would fail. This value is then mapped to the output video using -map. For reference, 0 represent no change to the brightness. The eq filter then takes the video returned by concat, and adjusts the value to a brightness of 0.3. The results are saved to the values of and for video and audio respectively. n specifies the number of segments, v specifies the number of output video clips, and a specifies the number of output audio clips. The first filter, concat, takes in a set of synchronized audio and video segments, concatenates them, and returns the resulting audio and video clips. , are values supplied by ffmpeg representing the video and audio streams of the 1st and 2nd inputs, in this case input1.mp4 and input2.mp4. Any value contained in brackets (), is a value that can be input or output by a filter. filter_complex specifies a series of filters that accept inputs and return outputs. * hstack_qsv, vstack_qsv and xstack_qsv filters * filtergraph syntax in ffmpeg CLI now supports passingįile contents as option values, by prefixing option name with '/' * ffmpeg CLI new option: -fix_sub_duration_heartbeat * hstack_vaapi, vstack_vaapi and xstack_vaapi filters * ffmpeg CLI new options: -stats_enc_pre, ![]() * QSV decoding and encoding for 10/12bit 422, 10/12bit 444 * WBMP (Wireless Application Protocol Bitmap) image format * VAAPI decoding and encoding for 10/12bit 422, 10/12bit 444 HEVC and VP9 * Add new mode to cropdetect filter to detect crop-area based on motion vectors and edges * ffmpeg now runs every muxer in a separate thread ![]() * ffmpeg now requires threading to be built * ddagrab (Desktop Duplication) video capture filter ![]()
