windows version - ffmpeg record not writing correctly

[t3therdev]

Which version are you using?

v0.13.1

Which operating system are you using?

OS

• [X ] Windows

Describe the issue

When getting inbound rtsp stream we are calling onpublish to record the stream to segments using this command:

runOnPublish: ffmpeg.exe -rtsp_transport tcp -i rtsp://localhost:$RTSP_PORT/$RTSP_PATH -vcodec copy -acodec copy -f segment -strftime 1 -segment_time 60 -segment_format mp4 ch3out%Y-%m-%d_%H-%M-%S.mp4

ffmpeg.exe is sitting in the same directory as the rtsp-simple-server.exe for testing.

The files are created properly and ffmpeg runs. But the videos will not play.

If i run the exact same command OUTSIDE of rtsp-simple-server, it works fine and file plays perfectly.

Describe how to replicate the issue

Replicate:
Push to the server, run onpublish command from above.
It saves the files and does everything, but the files won't play.

Do the same thing , but run the ffmpeg command (from the same folder as ffmpeg.exe and simpleserver) outside of rtsp simple server, it all works. (Of course change rtsp_port/path to the correct info).

for example:
ffmpeg.exe -rtsp_transport tcp -i rtsp://localhost:8554/ch3 -vcodec copy -acodec copy -f segment -strftime 1 -segment_time 60 -segment_format mp4 ch3out%Y-%m-%d_%H-%M-%S.mp4

Hello, i have various hypothesis about this.

First of all, try adding the -nostdin and -y flags to the ffmpeg command. In my personal scripts, i always use -nostdin and it allows to solve a lot of freezes and similar issues.

Second, i need to understand what you mean with "the videos won't play"

• they don't play in VLC? if that's the case, start vlc with the -vvv flag (verbose output) and report the output - maybe the SPS/PPS/iframes are missing and must be generated
• ffmpeg is stuck and doesn't go on? if that's the case, launch ffmpeg with the -loglevel verbose and report the output - maybe it could be a network problem
