ffmpeg Invalid argment while running example.ts #170

axacheng · 2021-11-29T12:23:17Z

Hi boony

First of all, thanks you for developing this awesome node library, it'd be very useful for me and make my life easier to build a live streaming cache CDN. However, by some reason, I cannot make it work as I'm not sure the server side issue or ffmpeg decode issue. I got Unable to find a suitable output format for 'cam' this error mesg and node process got exited. I didn't see any 'cam' keyword in my code and your rtsp-video-recorder, so I assume it might be came from ffmpeg ?

Could you please verify it for me ?

Thank you so much.

Hello, @axacheng
I am glad to see it's useful for other people )

So, as for your issue, I am not sure what can be the root cause of it. I didn't have a chance to find something similar so far. The most closer error message is:

09-23 09:29:41.525: E/Home(31343): [NULL @ 0x41f7f420] Unable to find a suitable output format for 'ffmpeg'
09-23 09:29:41.525: E/Home(31343): ffmpeg: Invalid argument

Just finger to the sky... Let's check whether your ffmpeg response the same if you query it directly.
Try:

ffmpeg \
    -rtsp_transport tcp \
    -i rtsp://USERNAME:PASSWORD@finallyhome.tplinkdns.com:6666/stream2 \
    -reset_timestamps 1 \
    -strftime 1 \
    -strftime_mkdir 1 \
    -hls_time 600 \
    -hls_list_size 0 \
    -hls_segment_filename %Y.%m.%d-%H.%M.%S.mp4 \
    ./playlist.m3u8

Also, I am not sure about your DESTINATION variable. Try to use absolute path instead of relative.

Let me know how is it going.

axacheng · 2021-12-01T15:39:23Z

Hello Boonya

Thank you for quick reply. I tried to run ffmpeg command from terminal and I got output file with current timestamp as well as playlist.m3u8 file. Everything just worked from ffmpeg command!

From my last thread, I used DESTINATION="." for environment variable but I just used absolute path now. DESTINATION="/home/axa/" , but still got same error - cam:Invalid argument. I don't know where to set cam argument and not sure what suitable output format meant from npm run example command output ~

Could you let me know what ffmpeg version you use and what nodejs version is ?

Thank you

boonya · 2021-12-01T15:45:02Z

Interesting.
Actually I tried it with latest nodejs which is 16 currently, but couple of minutes ago I tried to run it under 10.24.0 (which I see from your logs) and it works as. expected.

boonya · 2021-12-01T15:54:22Z

I have it tested on my Macbook Pro M1 where (nodejs 10.24 & nodejs 16.13) ffmpeg version installed:

I have an idea!
Try to pass additional env variable TITLE with value which does not contain spaces and any special characters.
Lets see what we get

E.g.

export TITLE="test-cam"

Here is the "cam" word you may be experiencing this issue about.

axacheng · 2021-12-01T16:11:16Z

boonya · 2021-12-01T16:14:15Z

Yep, I got the issue

So, temporary workaround is to assign you own TITLE with no spaces inside.

axacheng · 2021-12-01T16:15:33Z
