How to implement filters？

[jd7352]

This is a great project and I have successfully experienced its power. Now I want to implement watermark or logo while transcoding, how can I pass parameters such as overlay coordinates, logo's url through program.yml ? Please give pointers, thanks!

I can successfully execute the following commands in the ~/ffmpeg_encore/ directory: ffmpeg -i input.mp4 -vf "movie=logo.jpg[logo];[0:v][logo]overlay" output.mp4 ffmpeg -i input.mp4 -filter_complex "movie=logo.png[logo];[0:v][logo]overlay" output.mp4

But entering the configuration through program.yml always returns an error. The configuration file is as follows:

`name: program description: my profile scaling: bicubic encodes:

• type: X264Encode suffix: 2069 twoPass: true height: 720 filter_complex: "movie=logo.png[logo];[0:v][logo]overlay" params: ss: 00:00:00 t: 00:00:10 b:v: 2069k maxrate: 3104k bufsize: 4138k r: 25 vsync: 1 pix_fmt: yuv420p force_key_frames: expr:not(mod(n,96)) profile:v: main level: 3.1 x264-params: deblock: 0,0 aq-mode: 1 bframes: 6 keyint: 192 keyint_min: 96 ref: 4`

filter_complex is not valid in encore encoding profiles, the correct keyword is filters. Also because of how the filter chain is put together by encore, in this case you will need to use a null filter to save the video input. You will also need to include the full path to your logo. So In your profile, you could use something like

    filters: ["null[my-filter-in];movie=/full/path/to/logo/logo.jpg[logo];[my-filter-in][logo]overlay"]

Also, instead of specifying the ss and t parameters in the profile you could set seekTo and duration on the job you post in.

marvelous! Following your method got the results I was hoping for, thanks a lot! In addition, the use of ss and t parameters in the configuration file is because I need to generate a 10-second video preview in a single transcoding task at the same time, my configuration should be correct (currently it works, I am in Simplified the configuration file behind when submitting an issue)?

Glad to hear your problem is solved!

Oh I see, with that use case it makes sense to use ss and t the parameters like that.
