macos - How to interleave audio video in ffmpeg library ...
https://stackoverflow.com/questions/12142562/how-to-interleave-audio-video-in-ffmpeg-library

I am using av_interleaved_write_frame () to write the file. but it is too time consuming. So i want to replace it with av_write_frame ().
use ffmpeg to convert interleaved raw yuv/pcm to ...
https://video.stackexchange.com/questions/27518/use-ffmpeg-to-convert-interleaved-raw-yuv-pcm-to-compressed
I'm always impressed how smart FFmpeg has been designed so giving this a go. Can I use FFmpeg to convert part of a file to a compressed video file w/audio? The file I have consists of YUV420 frames interleaved with (floating point) audio PCM. So raw video & audio. I would like to convert part of it, so would want to give an offset into the file.

You can select the output format of each frame with ffmpeg by specifying the audio and video codec and format. For example to compute the CRC of the input audio converted to PCM unsigned 8-bit and the input video converted to MPEG-2 video, use the command: ffmpeg -i INPUT -c:a pcm_u8 -c:v mpeg2video -f crc -.

Interestingly, FFmpeg converted the MP3 audio to AAC and muxed the file without so much as an informational message. Just for fun, I converted audio.mp3 into a wav file and tried this: ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a copy muxed.mp4. As before, FFmpeg converted the WAV file to AAC and produced the muxed file.

[FFMPEG] Non-Interleaved AVI in Concatenate - VideoHelp Forum
https://forum.videohelp.com/threads/396128-%5BFFMPEG%5D-Non-Interleaved-AVI-in-Concatenate
AVI = Audio Video Interleave. I don't know if ffmpeg is telling you the input is non-interleaved or if it's the output, although interleaving requires a bit more "overhead" so if the file size has grown it suggests the input was non-interleaved but the output is interleaved. You can join AVIs with VirtualDubMod or VirtualDub2 and control the ...
