print("Pafy Vid Created!")
audio = vid.getbestaudio()
print("Pafy Audio Created!")
try:
 // self.FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
 self.vc[ctx.guild.id].play(FFmpegPCMAudio(Song['source'], **self.FFMPEG_OPTIONS), after=lambda _: E.set())
 print("Playing Music!!!")
except Exception as ex:

Wrong video duration reported after concatenating video files in BASH script
13 novembre 2012, par BenjenI am trying to merge three video files (each 16 seconds long) into one file using ffmpeg. Since they are in mpeg format I am simply trying to concatenate them into one file using
cat
command. The problem is that when I run the resulting file (video.mpg
) it is reported as being 16 seconds long (same as the first concatenated video). Interestingly when I play the file in VLC, I can watch the whole 48 sec of video, even though the video progress bar also only reports up to 16 secs.It almost seems like the file "properties" (e.g. duration, etc) are not updated after the additional two videos are added using the
cat
command.Would appreciate any suggestions on how I might solve this.
The following is the relevant section of the BASH script I have created :
mkfifo intermediate1.mpg
mkfifo intermediate2.mpg
mkfifo intermediate3.mpg
ffmpeg -i "./tmp/final01.mp4" -qscale 1 -y intermediate1.mpg < /dev/null &
ffmpeg -i "./tmp/final02.mp4" -qscale 1 -y intermediate2.mpg < /dev/null &
ffmpeg -i "./tmp/final03.mp4" -qscale 1 -y intermediate3.mpg < /dev/null &
echo "[audioforge] Stitching files "
cat intermediate1.mpg >> ./tmp/video.mpg
cat intermediate2.mpg >> ./tmp/video.mpg
cat intermediate3.mpg >> ./tmp/video.mpg
# Convert back to mp4 format.
ffmpeg -i "./tmp/video.mpg" -qscale 1 -y "./tmp/video.mp4" -
Using FFMPEG to stream from one computer to another on the same network
23 juin 2021, par Andy BMy problem


I have a device with cameras, and I can access the video from those cameras via RTP over RTSP.


I have an Ethernet cord going from the device to my computer, and I can see/record the video from the device using FFMPEG or VLC. I just use
rtsp://<ip of="of" device="device">/path/of/stuff.extension?camera=<number></number></ip>
like the user's manual says.

This works great, but ultimately, I want to stream this video to another computer on the same network. I have tried many different things, but nothing seems to work.


Theoretically, this FFMPEG command should work, but I'm messing up somewhere and I don't know why or where.


ffmpeg -rtsp_transport tcp -i rtsp://<ip of="of" device="device">/path/thing.extension?camera=1 \ 
-f mpegts udp://<ip of="of" computer="computer" i="i" want="want" to="to" send="send" it="it">:<some port="port">
</some></ip></ip>


In VLC on the other computer, I want to be able to just go into VLC and start a network stream that looks like
udp://@<ip address="address">:<port></port></ip>


What I thought would work, but doesn't


If the camera device has IP
A.A.A.A
, and the computer getting and streaming the video isB.B.B.B
, and the computer I want to watch the streamed video on isC.C.C.C
then is the following correct ? Because it does not work for me...

Computer A :


ffmpeg -rtsp_transport tcp -i rtsp://A.A.A.A/path.ext?camera=1 -f mpegts udp://B.B.B.B:10001



Computer B (in VLC) :
udp://@B.B.B.B:10001
