[FFmpeg-user] Transcoding PCM to AAC

[Mauricio Ulargui]

Hi,
I'm transcoding several old videos to MP4/AAC/H264, most of them were recorded using digital cameras. I'm getting an error with those that have PCM audio, below is an output detail. Any suggestion/ideas?
 
ffmpeg -i "video.AVI" -acodec aac -strict experimental -vcodec h264 "video.mp4"
