Hi, I am trying to run the command from the centos os but i am getting the following error.

1 file was 14 mb and 7 mb, Is there any file restriction or format should i need to pass. Please clarify.

**xvfb-run -s "-ac -screen 0 1280x1024x24" ffmpeg-concat  -t circleopen -d 750 -o opengl/javio.mp4 /home/captionsly/app/media/2/output/1/6990_output.mp4 /home/captionsly/app/media/2/output/1/9622_output.mp4**

Those file sizes should be fine.

Can you run those ffmpeg commands directly and see if ffmpeg throws an error?

ffmpeg -i /home/captionsly/app/media/2/output/1/6990_output.mp4 -y -pix_fmt rgba -start_number 0 "scene-0-%012d.raw"

ffmpeg -i /home/captionsly/app/media/2/output/1/9622_output.mp4 -y -pix_fmt rgba -start_number 0 "scene-1-%012d.raw"

These commands break the input mp4 videos into individual frames and it looks like ffmpeg is complaining that the conversion process is failing. This could be because of some random mp4 formatting issue, but it's impossible to tell without the source mp4 files.

Thank you @transitive-bullshit ,

I am using centos to run those commands as per https://www.npmjs.com/package/gl#how-can-headless-gl-be-used-on-a-headless-linux-machine

When i run these command in ubuntu it render fine. Is there any options need to be changed in xvfb-run -s "-ac -screen 0 1280x1024x24" The resolution part of my video is 1920x1080x24

these are the input mp4 files https://drive.google.com/open?id=1SR5_yNjSj97IUW0Uq_hqPRVKmjVe4uWq https://drive.google.com/open?id=1GWfLcEUf8FZnasVBvkz5To6P-dl5bCef https://drive.google.com/open?id=1N3Hyy3bviO98gWIYLjfawQNB_O45tsaR

I have tried this commands

ffmpeg -i app/media/2/output/1/2105_output.mp4 -y -pix_fmt rgba -start_number 0 "scene-0-%012d.raw"

Here is the output and could you please clarify whether the output was correct?

Same issue here - as far as I can tell I'm having issues during extract-video-frames execution. @transitive-bullshit can You please tell why do You have '-pix_fmt', 'rgba' output option? And are the changes inside https://www.npmjs.com/package/ffmpeg-concat/v/1.0.14 version? UPD: nevermind about version. I found that there were changes about audio :)

maksym-plotnikov commented 4 years ago

Also @transitive-bullshit why you're not using Yours https://github.com/transitive-bullshit/ffmpeg-extract-frames to extract frames? I see there are additional output options regarding fps and '-vsync', 'vfr'? Please can You tell me why do You need them there?

transitive-bullshit commented 4 years ago

@maksym-plotnikov I'm not sure; feel free to create a fork, experiment, and let us know your findings. 😄

capezzbr commented 4 years ago

In my case I'm having a similar issue when the temporary directory gets around 100GB

capezzbr commented 4 years ago

My solution was to invoke concat on a subset of the videos, then invoke concat again on the partial videos. For instance let's say that I have 100 videos, and I decide to process 10 videos at the time, I'll be invoking concat on video 1...10 then 11...20 until 91-100 and this will give me in output exactly 10 partial videos as result. At that point I can invoke concat on the resulting 10 partial videos generating the final video result of concatenating the 100 videos. This will help limit generating the temp files that will later fill up the /tmp directory, root of the issue for me.

capezzbr commented 4 years ago

Actually that didn't work. I've assumed that only the frames necessary for the transition between videos would be processed instead of all the frames. My new solution simply uses an external HD and limits the length of the video

transitive-bullshit commented 4 years ago

@capezzbr see https://github.com/transitive-bullshit/ffmpeg-concat/pull/23 for the approach you're describing.

Both approaches have their pros and cons. In particular, the more optimal approach that touches less frames requires more complex ffmpeg inputs and from lots of experience, ffmpeg tends to become unstable the more complicated your inputs and processing pipeline becomes. That's why it's not the default approach at the moment.

If you want to cut down on the temp space required, you can use the --frame-format png option to store each frame compressed instead of the faster uncompressed raw format that's the default.

transitive-bullshit commented 4 years ago

(or --frame-format jpg should work too)

capezzbr commented 4 years ago

@transitive-bullshit thanks for the context. I'd rather optimize for speed vs space, so I've opted to use an external disk for the temporary frames data. Also, it would be great if https://github.com/transitive-bullshit/ffmpeg-concat/pull/23 could be taken to a mergeable state and used as default way. That will both optimize time and space. Anyways really appreciate you taking the time to build this library, it works pretty well 👏
