• ffmpeg - how to pass all streams audio/tmcd, etc from input->output unchanged

  22 avril 2021, par QRrabbit

  Please help me, with hopefully specific ffmpeg arguments to include in my video encoding.

  


  My work is only related to video stream, so this is the only one I'm changing.
I receive a .mov file(s) that have already been pre-compiled for a specific broadcaster, some of those selfcontained videos have 4 streams (1 video, 2 audio, and some other timecode stream). Others have up to 17 streams : 1-video, 15-audio streams and the final one is unsupported tmcd.

  


  My process pipeline includes only re-encoding/re-processing video stream, and everything else I need to pass along to the output file - all other streams without any changes or alterations.

  


  During this step of encoding, I insert icon.png into position 5:21 from sec 2-3, from 4-5, and from 6-8. To achieve this, I use map option, so my encoding string looks like this :

  


  ffmpeg -i in.mov -i icon.png -i icon.png -i icon.png
    -filter_complex "  [0][1]overlay=5:21:enable='between(t,2,3)'[v1];
                      [v1][2]overlay=5:21:enable='between(t,4,5)'[v2];
                      [v2][3]overlay=5:21:enable='between(t,6,8)'[v3]" -map '[v3]' -map 0:a
    -c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6
    -c:a copy -c:s copy -y out.mov


  


  The problem is that the out.mov only shows with 2 streams instead of 17 (1-video, and 2-audio). All other 15 streams are truncated completely.
Reading some other stackoverflow posts I found a way to transfer all other streams, is by using -map 0 :

  


  But as I tried adding -map 0 on my last line :

  


      ...
    -map 0 -c:a copy -c:s copy -y out.mov


  


  but this doubles the number of streams from 17 to 34 - also double in output file size.
If I remove map '[v3]' -map 0:a from my original encoding string and only include -map 0, I get correct number of streams, but, of course icon.png is not getting inserted at the right time. What should I do ?

  


  If there's a way to re-map my -filter_complex to overlay images without using this -map option ? Or, be specific at what each -map referring to ?

  


  If not, what other arguments/parameters can I use, if such option even exists, to copy all streams, subs and all other audio, potentially some other signal for audio impairment, if such exists.

  


  Please help, so I can finally wrap my output and submit my work.

• Use Google Analytics and risk fines, after CJEU ruling on Privacy Shield

  27 août 2020, par Joselyn Khor — Privacy
  EU websites using Google Analytics and Facebook are being targeted by European privacy group noyb after the invalidation of the Privacy Shield. They filed a complaint against 101 websites for continuing to send data to the US. 

  “A quick analysis of the HTML source code of major EU webpages shows that many companies still use Google Analytics or Facebook Connect one month after a major judgment by the Court of Justice of the European Union (CJEU) - despite both companies clearly falling under US surveillance laws, such as FISA 702. Neither Facebook nor Google seem to have a legal basis for the data transfers.”

  

  The Privacy Shield previously allowed for EU data to be transferred to the US. However, this was invalidated by the Court of Justice of the European Union (CJEU) on July 16, 2020. The CJEU deemed it illegal for any websites to transfer the personal data of European citizens to the US. 

  They also made it clear in a press release that “data subjects can claim compensation for inadmissible data exports (marginal no. 143 of the judgment). This should in particular include non-material damage (“compensation for pain and suffering”) and must be of a deterrent amount under European law.” Which puts extra financial pressure on websites to take the new ruling seriously.

  Immediate action is required after Google Privacy Shield invalidation

  The Berlin Commissioner for Data Protection and Freedom of Information therefore calls on all those responsible under its supervision to observe the decision of the ECJ [CJEU]. Those responsible who transfer personal data to the USA - especially when using cloud services - are now required to immediately switch to service providers in the European Union or in a country with an adequate level of data protection.

  As the ruling is effective immediately, there’s a pressing need for websites using Google Analytics to act, or face getting fined.

  What does this mean for you ?

  If you’re using Google Analytics the safest bet is to stop using it immediately. 

  "Neither Google Analytics nor Facebook Connect are necessary for the operation of these websites and could therefore have been replaced or at least deactivated in the meantime."

  If you still need to use it, then you’ll need to inform your visitors via a clear consent screen. This banner needs to make clear their personal data will be sent to the US, and to educate them about any potential risk related to this. They will then need to explicitly agree to this. 

  Another downside of cookie consent screens is that you may also suffer a damaging loss of visitors. After implementing cookie consent best practices, the UK’s data regulator the Information Commissioner’s Office (ICO) found a 90% drop in traffic, “implying a ninety percent drop in opt-in rates.”

  With an acceptance rate for such consent screens being lower than 10% your analytics becomes guesswork rather than science. 

  Looking for a privacy-respecting alternative to Google Analytics ?

  Privacy compliant Matomo Analytics is one of the best Google Analytics alternatives availalble. 

  With Matomo you’re able to continue using analytics without facing the wrath of both the GDPR and the CJEU. Matomo On-Premise lets you choose where your data is stored, so you can ensure no data is processed in the US. 

  Matomo is privacy-friendly and can be tweaked to comply with all privacy laws. Including the GDPR, HIPAA, CCPA and PECR. The benefits of this include : not needing to use tracking or cookie consent screens (like with GA) ; and avoiding fines because no personal data is collected. You also get 100% accurate data and the ability to protect your user’s privacy.

• On-the-fly transcoding using derolf/transcoder

  8 septembre 2015, par user1811678

  https://github.com/derolf/transcoder

  I need to transcode locally and playback locally in my project, no other external connection to the server.
  It is a good source of doing on the fly transcoding by ffmpeg.

  In my case i have to transcode it to mp4 as it could perform faster.
  However i run into following problem, and i need some help in here to fix it.
