Bug Report Local .mp4 files produced by OBS are missing keyframes

[Deleted123]

Following the last 5 updates to OBS, which made local .mp4 files produced by OBS to crash VLC, I have been using ffmpeg to convert the files into playable ones using the following command line:

ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mp4

This has been working fine until 3 days ago, when a new update apparently screwed up the encoding process, which rendered my local recordings useless.
After the update, upon using the aformentioned code, I get the following errors:

E:\My Recordings\Captured>

I need to mentioned that the output file only contains the audio track, not the video track, which suggests that the .mp4 files produced by OBS after the last update(s) lack keyframes.

This always happens with recordings longer than 2 hours.

 

[Lain]

I was unable to replicate. I would suspect your settings are involved. We didn't particularly change the MP4 code, nor did we stop writing keyframes to MP4 files.

Please include an OBS log file as well.

Since making another post would just be pointless, and since I have already captured your attention, I would like to point out that the file naming function derps out on me.
Using the following code for the file naming, it is completely discarded:

E:\My Recordings\Captured\$Y$0M$0D-$0d$0m$0s.mp4

Despite the fact that I am using that code there, it doesn't respect the naming policy, and just uses the default one.

 

[Deleted123]

The issue has been resolved with a quick reinstall. In the past 2 weeks I have been using binaries of a different version than the one installed, thus the discrepancy in the registry/file versions.
That was probably the issue with my encoding process.

Having said that, there still remains 1 issue: file naming... still does not work the way it is set up.
Using this code:

E:\My Recordings\Captured\$Y$0M$0D-$0d$0m$0s.mp4

Defaults to this naming policy:

2014-09-07-2336-03

 

[Jack0r]

Using $T will give you:
2014-10-07-2350-28
In your code you had: 20140907-$0d3603.mp4 because there is no $0d.

I am also having a problem to reproduce your keyframe problem. In the recent time I made several recordings for 3-4 hours, with high and low bitrates, different settings and encoders, and did not encounter a single problem with the files :/

 

[Deleted123]

Thank you Jack0r, for pointing that out. It's amazing how little things can slip past someone's eyes.

* The issue is that the video track is completely black. The OBS's settings were the same for both v0.365b and v0.637b.
Today I installed the old v0.635b and I have no issues with recording long videos.

I probably should add that:

2200 kb/s

[d2014]

Same here.

Win7 X64
OBS x32

Bitrate 3000kb/s
AAC 128 48kHz stereo

720p/25, aero deactivated

preset veryfast

Audio works fine, video is not present. Same ffmpeg error as above.
I did not clean the settings after going from 0.635 to 0.637

 

[Deleted123]

The way I'm avoiding this issue, is to record in .FLV format, and then use this piece of code (saved as .BAT):

:: cmd /k "cd /d %~dp0"
@echo off
@title Converter: ffmpeg -i ?.flv -c copy -copyts ?.mp4
ffmpeg -i %1 -c copy -copyts %1.mp4

To convert the files, I simply drag the files on top of the .BAT file.
Don't forget to install ffmpeg library on your machine.

I can record videos up to 12 hours in length without a problem, and if OBS crashes in the process, the files are still accessible, and it only takes around 1 minute to convert a 1 hour long video.

In the 0.638b update Palana added a fix that hopefully fixes the MP4 corruption, but in general ViccroyHD does what I would recommend anyone that needs the recorded files no matter if Power goes out or OBS crashes.
FLV files will simply work and can be easily converted.
