ffmpeg Question RTSP to HLS

[Brucek2839]

Hello,
I am starting to master the use of ffmpeg and have run into a error with the following script.  The RTSP stream works fine in ffplay.  From the script is looks to connect to the camera but I am stumped by the no output file error.  Any assistance would be appreciated.
Thank you,
Bruce

Sorry your FFmpeg line is truncated

Code:

ffmpeg -v verbose  -i rtsp://admin:12345@192.168.1.138:554/Streaming/Channels/1?transportmode=unicast  & profile=Profile_1 -vf scale=1920:1080  -vcodec

- add quotes around the URL that you add that you use in the batch file that works with ffplay
- the last parameter is typically the filename, but you can use the dash (-) to send it to standard output for the extra.
- remember to not use -v verbose with the extra.

As well as needing quotes around the url, it looks like you've got some extra spaces in there too.

"rtsp://admin:12345@192.168.1.138:554/Streaming/Channels/1?transportmode=unicast&profile=Profile_1"

[mvallevand]

I also noted the thread title, you don't want HLS you want -f mpegts

to test your batch file

webcam.bat | ffplay -i pipe:

Martin

[Brucek2839]

Added the Quotes and took out the extra spaces and this is what I get now..

Why don't you just zip up webcam.bat, attach it and we can look at it properly?

Martin

[Brucek2839]

Martin,
Sounds like a great idea. Thank you,,,


ffmpeg -v verbose -i "rtsp://admin:12345@192.168.1.138:554/Streaming/Channels/1?transportmode=unicast&profile=Profile_1" -vf scale=1920:1080 -vcodec

[mvallevand]

Is that zipped and attached?

Martin

[Brucek2839]

that is all of it...

[mvallevand]

But is is not what I asked for.
