• Anomalie #4321 : Conformité des Message-Id de envoyer_mail

  19 avril 2019, par jluc -

  Cependant cet $uniq sert aussi à construire d’autres éléments du mail, notamment les lignes qui séparent des parties du mail. Je ne sais pas si un gênera ou pas ces autres éléments. À défaut il pourrait y avoir un $uniqid avec le et un $uniq comme l’actuel.

• ffmpeg hevc h265 4k 10 bit

  14 juillet 2017, par Ali Jose

  I want to be able to encode 4k videos in TS files having video codec as HEVC at constant bitrate 20 Mbps, dolby audio (2 channel front L & R). This is the spec sheet as provided from my client http://159.8.5.10:3001/download/4k-specs.xlsx Im using this code :

  I used this code at first to produce a sample which conforms to their spec sheet, however the playback was not smooth neither on my side nor on their side :

  ffmpeg -i input.mov -pix_fmt yuv420p10le -c:v libx265  -b:v 19.5M -minrate 19.5M -maxrate 19.5M -muxrate 20M -x265-params "level=6.2" -r 50 -s 3840x2160 -c:a ac3 -b:a 384k -minrate 384k -maxrate 384k -channel_layout 3  output.ts

  the produced sample is found in the following link : http://159.8.5.10:3001/download/two_mns_sample.rar

  The client sent me this sample, he told me it is provided by another supplier and it is approved by their end (it matches their spec sheet and plays smoothly in their broadcast software), the sample is found under the following link : http://159.8.5.10:3001/download/approved-4k.rar

  Then the client sent me another sample, they also said that it is approved by their side (matched their specs and plays smoothly in their broadcast software) found under the following link : http://159.8.5.10:3001/download/approved-4k-2.rar

  When examining well the second approved sample, I noticed that it doesnt meet the spec sheet 100% but the differences are minor (level @ 5.1 instead of 6.2 and dolby 5.1 instead of dolby Stereo... so minor differences) but as they described, it played back smoothly in their broadcast playback. So we can understand from that that they are a bit flexible.

  My 4k source file is an mov Prores 4444, 23.97 fps, 10 bit depth, 444 chroma subsampling, variable bitrate (around 950 Mbps). To find out more info about the input file, please go to this link (MediaInfo txt export) : http://159.8.5.10:3001/download/4k-original.txt

  This is a 2mns sample trimmed clip from my original file (couldnt upload the whole source file since its 800 GB !) : http://159.8.5.10:3001/download/original-2-mns.mov

  I need an ffmpeg code that can generate a sample that complies to their specification sheet and can be played SMOOTHLY in their technical department, it was mentioned they are using 4k playbox technology (maybe airbox but it was not clear, but what we can assure is that they use good instrument for broadcast, they dont go for below average instrument/software), I need to send them samples that they later check and play on their playback system and get approved.

• ffmpeg not working for some reason correctly on linux with discord bot [closed]

  12 juillet 2020, par billybob joe

  Does anyone have any experience getting a discord music bot working with ffmpeg on linux, I switched over from my windows vps to linux ubuntu 18.04 and installed ffmpeg which was a one line command "sudo apt-get install ffmpeg". Everything worked fine when I run the discord music bot on my windows vps and local pc. However when I do so on my linux vps the bot works fine, except the music commands. The bot will join the channel and just stay green and will not output any errors at all. It also does not crash, and will continue to run.
