Run Command/Process in Background but return the return code
14 juin 2019, par techsavyI am Looking to run ffmpeg via subprocess, start the command in the background but return a return code so that further steps can be taken based on that return code. (stdout, stderr) = metadata.communicate is throwing all sorts of errors perhaps due to the process still being run.
metadata = Popen(['/home/linuxbrew/.linuxbrew/bin/ffmpeg', '-i', '/mnt/sniops-ffmpeg/' + str(content.get('asset')), '-i', '/mnt/sniops-ffmpeg/' + str(content.get('asset')), '-lavfi', 'libvmaf=model_path=/opt/vmaf/model/vmaf_4k_v0.6.1.pkl:psnr=1:ssim=1:log_fmt=json:log_path=/mnt/sniops-ffmpeg/vmaf_scores/blackmonday_test1.json', '-t', '00:00:20.00', '-f', 'null', '-', '&'], stdout=PIPE, stderr=PIPE) -
Permission denied when trying to call ffmpeg on heroku
1er décembre 2013, par chuck wI have a rails 3.1 web app on Heroku (cedar) that that allows users to post stories with photo and video attachments using the paperclip gem (3.5.1). Uploads are stored on s3. This has been working 100% for many months.
I have recently added video transcoding and thumbnailing to my dev machine with the paperclip-ffmpeg gem (1.0.1) and ffmpeg running locally. This is also working.
I've followed these instructions to build and install ffmpeg on heroku, and I've altered my Heroku app's path so that it reads as follows :
PATH: bin:vendor/ffmpeg/bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/binand my app's LD_LIBRARY_PATH so that it reads as follows :
LD_LIBRARY_PATH: vendor/ffmpeg/lib:/usr/local/libFinally, I've vendored ffmpeg into my app with the following structure :
When I commit and push these changes to Heroku and POST a story that has a video I get the following output on Heroku logs :
