[FFmpeg-user] Memory usage growing when using ffmpeg. Is this expected?

[Guilherme de Oliveira Costa]

Hi,



I am using ffmpeg record a video from a webcam, but the memory usage is very high, and keeps increasing with video length.

For example, I use an embedded device with 64 MB of RAM, and when I recorded a 30 minute video, I was left with 2MB of RAM in the last minutes of the recording.

I used valgrind to check for memory leaks, but I only found a 24 byte leak when the program finishes. Is this memory consumption expected for ffmpeg?

This is the ffmpeg command I used:

ffmpeg -f video4linux2 -s 320x240 -t 00:00:10 -i /dev/video0 out.mpg

Regards,
