Recording 1080p 60fps Crashes FFMPEG Encoder #3254

Closed HurricanePootis closed 1 year ago

HurricanePootis commented 4 years ago

Platform

Operating system and version: Arch Linux 5.7.12 OBS Studio version: 25.0.8-1

Expected Behavior

I set the level to 4.2, which proclaims that it supports up to 1080p 60fps output, and it should record/stream at 1080p 60fps

Current Behavior

OBS tells me encoder overload after a second of recording/streaming at 1080fps 60fps.

Steps to Reproduce

  1. Open OBS
  2. Use FFMPEG Vaapi as output
  3. Set level to 4.2
  4. Set output to 1080p 60fps (I use a bitrate of 6000)
  5. Record/Stream
  6. Crash

Additional information

I installed a custom patch to OBS that allowed me to record with h.265 through Vaapi, and I was able to record at 1080p 60fps with that.

Please provide the GDB backtrace of the crash.

HurricanePootis commented 4 years ago

Please provide the GDB backtrace of the crash.

I am not sure how to do a GDB backtrace of a crash. Sorry.

kkartaltepe commented 4 years ago

Until a backtrace is provided there is nothing we can do to help here, since this is likely a crash in your graphics drivers vaapi impl.

HurricanePootis commented 4 years ago

After some fiddling around, I managed to core dump obs-ffmpeg when it was overloading, and I got this when I ran the coredump through gdb coredump If I did something, please let me know. This was my first time doing something like this.

kkartaltepe commented 4 years ago

im not really sure what process you followed, but it looks like you are loading from a core dump which doesnt match the executables so there are no symbols... GDB recommends you use /home/borowski/obs-studio-portable/bin/64bit/obs-ffmpeg-mux to source the symbols perhaps you instead tried /home/borowski/obs-studio-portable/obs-plugins/64bit/obs-ffmpeg.so ?

Preferably run OBS in gdb to produce a usable backtrace with accurate symbols.

HurricanePootis commented 4 years ago

Is this good? second take

kkartaltepe commented 4 years ago

Are you sure that obs is not crashing? What if you attach gdb to obs instead of the muxer?

HurricanePootis commented 4 years ago

Because a coredump wasn't generated for ffmpeg.

@hdemiray This is regarding FFmpeg VA-API, which is Linux-only.

I'm experiencing the same issue. Crash when recording, but no crash when streaming. (FFmpeg VA-API).

fish: “obs” terminated by signal SIGSEGV (Address boundary error)

The stack trace elements before entry #4 all belong to the signal handler.

This is from an old version and was fixed long ago. Unrelated to the actual issue.

I'm experiencing the same issue. Crash when recording, but no crash when streaming. (FFmpeg VA-API).

Provide a stack trace please.

And all of your settings please.

Lepidos commented 3 years ago

obs

Lepidos commented 3 years ago

Is there any other way I can view the settings? OBS crashes on startup prompt if I choose optimize for recording. h264_vaapi is also not working for Recording

abbasmaheryar commented 3 years ago

h264_vaapi and hevc_vaapi is not working for me either. i'm running drivers from mesa-git, an AUR package. I'm using an rx 580 on Arch Linux

kkartaltepe commented 3 years ago

Provide a stack trace from gdb.

abbasmaheryar commented 3 years ago

Provide a stack trace from gdb.

I ran obs with gdb, but when I click record, instead of crashing due to a segfault, the program hangs and I am forced to kill the gdb process.

I don't know if this will be useful, but here is the output from running strace . Pardon me for providing such a large stack trace, but I am pretty sure you can find what you are looking for at the very last few lines of the file.

Here are my settings: pic-window-210228-1940-54

This is probably something different, and starts somewhere between FFmpeg 4.2.4 and 4.3.1. Resolution, FPS, or other settings don't seem to matter. With 4.2.4 I'm getting an invalid argument message, and with 4.3.1 or 4.4 this segfault (first time I'm trying out VAAPI with OBS Studio; it does seem to work with plain FFmpeg).

Here's a snippet of the same with some more symbols:

Once I've done some more looking into it, I'll open a separate issue, if still necessary.

Closing as this has been determined to be a dependency issue with specific versions of FFmpeg. Additionally, Custom FFmpeg Output is a scenario that we very much discourage.
