Truncated videos in multi input multi output ffmpeg command
1er août 2019, par Bhupendra FatnaniI am trying to copy videos from a CCTV DVR server (6 channels) using rtsp. How do I optimize my ffmpeg command ?
Below is the configuration :
ffmpeg version : ffmpeg-4.1.4-win64-static
CPU : Intel Core i7-8650U @1.9 GHz 2.11 GHz
RAM : 16 GBWhen I try to download from 3 channels, the videos seem to download fine, but when I use >=4 channels simultaneously, the video from channel 1 truncates almost after about 5 secs, and the output files are much smaller from channel 2 to 4, channel 5 video output has no issues.
For e.g. here are the output file sizes according to channels.
Channel 1 : 1.7 MB (truncated)
Channel 2 : 27.5 MB (approx 5 secs video loss in the beginning)
Channel 3 : 28.5 MB (approx 3-4 secs loss)
channel 4 : 29.5 MB (approx 2 secs loss)
Channel 5 : 30 MB (no issues found)Below is the command I am trying to use to download.
ffmpeg -rtsp_transport tcp -thread_queue_size 1024 -i rtsp://<input url="url" 1="1" /> -thread_queue_size 1024 -i rtsp://<input url="url" 2="2" /> -thread_queue_size 1024 -i rtsp://<input url="url" 3="3" /> -thread_queue_size 1024 -i rtsp://<input url="url" 4="4" /> -thread_queue_size 1024 -i rtsp://<input url="url" 5="5" /> -map 0 -vcodec copy -t 60 -y outputfile1.mp4 -map 1 -vcodec copy -t 60 -y outputfile2.mp4 -map 2 -vcodec copy -t 60 -y outputfile3.mp4 -map 3 -vcodec copy -t 60 -y outputfile4.mp4 -map 4 -vcodec copy -t 60 -y outputfile5.mp4
Below is the actual output :
