OSError: [Errno 32] Broken pipe

[youngboy52]

Hi, I followed your Pre-Requisits to build my own environment, but when I tried to generate videos using the following script: python render_video.py --expname NAME_OF_TRAINED_MODEL --size MODEL_OUTPUT_SIZE --identities NUMBER_OF_FACES, it reported errors in video writer:

Have you met the same problem? looking forward to your reply~

Hi @youngboy52,

I have not encountered this problem, but it looks like the issue is stemming from ffmpeg, not the StyleSDF code base.

I encountered the same problem. And then I run the command reported in the error message:

~/Environment/anaconda3/envs/pytorch3d/bin/ffmpeg -y -f rawvideo -pix_fmt rgb24 -s 1024x1024 -i - -pix_fmt yuv420p -crf 10 ~/Work/Avatar/StyleSDF/evaluations/ffhq1024x1024/final_model/videos/sample_video_0_elipsoid.mp4

And then I encountered the error:

And my solution is to replace the ffmpeg file under the ~/Environment/anaconda3/envs/pytorch3d/bin/ with the file ffmpeg downloaded from https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz.

Then the code works :)

The solution works for me. Thx!
