- Hello! I'm hunting for a ffmpeg expert to help me through an AV processing (Python) pipeline.
-
- The basic task is:
- - to receive a video track and an audio track
- - to insert a certain length of black at the start of the video track
- - if the audio is longer, to freeze the last frame of the video track until the audio has completed
- - to insert content into the audio track
- - to merge the audio track into the video track
-
- There are a couple of complications:
- - sometimes we receive just a video track, in which case we have to split off the audio Stream and use that
- - the content is ultrasonic, so it's important this information is not lost (I believe we can use .aac with .mp4)
-
- Initially I outsourced the task. I have a Python script that works. But it is slow, cumbersome, ugly.
-
- I've rewritten it cleanly. But I suspect ffmpeg is still not being used right.
-
- I'm looking for someone who is familiar with the API to review the ffmpeg calls.
-
- Also I've found https://github.com/kkroening/ffmpeg-python
-
- It might be nice to use that!
-
- Please send me a PM, or email pi!pipad!org if this sounds of interest.
