[FFmpeg-user] ffmpeg on low power hardware

[John Saturday]

Sorry but your rtsp stream (video and audio) is a very badly or
scrambled like with a Macrovision. Only work two step encoding:

ffmpeg -vsync 2 -async 1 -i "rtsp://.../stream.mp4" -f matroska -c:v
rawvideo -r:v 25 -c:a pcm_s16le stream.mkv

ffmpeg -vsync 0 -async 1 -i stream.mkv -f mp4 -c:v libx264 -b:v 1040k
-r:v 25 -c:a libfaac -b:a 128k output.mp4

See your stream errors:

ffmpeg -vsync 2 -async 1 -i "rtsp://.../stream.mp4" -f mp4 -c:v
libx264 -an -y /dev/null

No pain, no gain... That's all.
