FFMPEG проблема записи потока

 ,

Добрый день! Настраиваю видео наблюдение. Софт: ос ubuntu, OpenRTSP+ffmpeg+motion В виду того что motion не дружит с RTSP, пришлось прикручивать ffmpeg, реализовал это таким образом motion считывает с камеры mjpeg поток, как происходит движение, срабатывает скрипт такого содержания

#!/bin/bash

# We are using two variables
# 1 — camera name
# 2 — directory name (where file will be stored)

# Generate filename
start=cam${1}
dt=`date +%Y%m%d%H%M%S`
FILENAME="${start}-${dt}.avi"
echo $FILENAME

if [ "$1" -eq 15 ]
then
 
/usr/bin/openRTSP -v -t rtsp://172.168.0.${1}:554/live/ch00_0 | ffmpeg -i - -y -r 10 -s hd720 -b 512k -vcodec copy /rec/$2/$FILENAME
fi
И начинается запись события в хорошем качестве, при чем учитывая то что я копирую поток, проц не нагружается. Все отлично работает с камерами AirCam, а вот с axis M1114 и axis M1031-w проблема, при воспроизведении записи скорость прокрутки не реально быстрая, в свойствах файла вот какие параметры: Скорость передачи данных: 369501кбит в сек частота кадров: 1200000

вывод ffmpeg при записи:

root@zm:/etc/motion# sh /root/bin/recordstart.sh 13 cam13
cam13-20131220095506.avi

Started playing session
Receiving streamed data (signal with "kill -HUP 11720" or "kill -USR1 11720" to terminate)...
[h264 @ 0x93adc40] max_analyze_duration reached
[h264 @ 0x93adc40] Estimating duration from bitrate, this may be inaccurate

Seems stream 0 codec frame rate differs from container frame rate: 2400000.00 (2400000/1) -> 25.00 (25/1)
Input #0, h264, from 'pipe:':

в общем как то так, подскажите как можно снизить bitrate? ведь это не реально bitrate=1994460.8kbits/s. Пытался настроить камеру, но ни какого эффекта это не дало.

Замени ffmpeg на cat.

/usr/bin/openRTSP -v -t rtsp://172.168.0.${1}:554/live/ch00_0 > /rec/$2/$FILENAME

Не совсем понял что такое «Cat»
