SSR produces a nearly empty file #227

Open unfa opened 10 years ago

unfa commented 10 years ago

I guess it's just the header.

My MKV file after about an hour of recording is 3,4 kB is big. Can't hide I'm not happy with this. It happened before when I used other programs like Kazam.

Any idea what can cause this?

I have no SSR log, but here's the hexdump of produced MKV file:

It happens to me when I tell it to record audio but I don't have the appropriate audio system running. (that is, I use JACK, and when I don't have qjackctl open it does that.)

MaartenBaert commented 10 years ago

When you start the recording in SSR, SSR will actually wait until both the video and audio input start before it starts writing. This is necessary for synchronization. If your audio system never starts (for whatever reason), then you will end up with an empty file.

You can avoid this by making sure that the timer on the recording page is actually running before you continue. Maybe I should show an error message when the inputs take more than 10 seconds to start, that would also avoid problems like this

unfa commented 10 years ago

I guess even some bigger message could be good - like a red flashing box in a corner of the screen or something - so it can't be overlooked.

Yes an explicit warning that nothing is recording would be a very, very good thing. There's nothing worse than finishing the hard recording work only to realize that it's all wasted and gone. The program could for example check every second if the output file is growing in size or not (it seems to check this already maybe just monitor it for sanity).

I wonder if sound notifications help with this?

There are sound notifications for all error messages (but not warnings). So a normal error would already trigger the notification.

unfa commented 10 years ago

Yes, but the sound notifications seem to leave their mark in the recording, so it's not suitable for no-editing production like simple screencasting.

What do you mean, leave their mark? There's a delay before the recording start, the notification should not be recorded.

unfa commented 10 years ago

They were clipped but still audible on my test recording.

MaartenBaert commented 10 years ago

I guess it depends on the delay of the entire audio system. The current delay is sufficient for me, but maybe the ALSA-to-JACK bridge you're using adds an additional delay.

What can i do ?

MaartenBaert commented 10 years ago

Can you send me the log file in .ssr/logs? It may contain more information.

The 'total time' is running so your inputs are OK. I suspect there's a muxing problem. I've recently made some changes to the muxing code that should improve compatibility with newer versions of libav (such as those used by Ubuntu 14.10, maybe Debian uses them too, I can't tell without the full log).

tannx commented 10 years ago

@MaartenBaert

This my full log of running ssr 0.3.0

MaartenBaert commented 10 years ago

You are using a version of libav that's so new it hasn't arrived in Arch Linux yet, so I haven't actually tested it. First, try recompiling the very latest SSR from the master branch. It contains a number of improvements related to libav compatibility (I do most of my testing with ffmpeg) which may be enough to solve your problem.
