• Audio along video processing together by opencv

  25 février 2015, par user3397178

  I am going to do some video processing so that I need my audio signal as well. I wanna develop a framework which extracts the frames of an input video file, processes (like tracking an object, etc) and then combines all frames together to have a new video. As I did it by means of Opencv, it is so straightforward. But as I know, OpenCV does not handle the audio signal along with video. The important point which I really have to do is to have a processed video along with sound. I would like to have the original sounds after processing in the new created video.

  I have heard that, I can do Audio processing with ffmpeg and video processing by Opencv, but I don’t have any opinions regarding that. It would be really appreciated if you give me a hint, a general overview or any possibilities for this task. Is is possible to integrate these two libraries (OpenCv, ffmpeg) together and do the mentioned task ? If so, how can I do that ? (any help, hint or suggestion is appreciated)

  thanks in advance
  Bests,

• how to add text to the video in android ?

  4 octobre 2024, par Sajad Norouzi

  In my app I record a video and I wanna overlay the url of my company on the right bottom of that video. I record video with MediaRecorder and there is no problem with the recording, but for adding text to the video I haven't been successful. I searched and found some library like FFmpeg and JavaCV which let user overlay a text on the video but I don't know if there is any way for using them in Android. after that found OnPreviewFrame which returns each frame of the camerapreivew. I want to get all frames after user touch record button and draw text using canvas to each frame and then save all those frame together until recording video stops, and videos duration are fix and 15 seconds. Is it a good solution ? if it is, how should I implement OnPreviewFrame function ? I know how to draw canvas but I don't know how to convert data[] to the bitmap.
