  What is Google Analytics data sampling and what’s so bad about it? - Joselyn Khor Piwik
  What is Google Analytics data sampling, and what’s so bad about it? Google (2019) explains what data sampling is: “In data analysis, sampling is the practice of analysing a subset of all data in order to uncover the meaningful information in the larger data set.”[1] This is basically saying instead of analysing all of the data, there’s a threshold on how much data is analysed and any data after that will be an assumption based on patterns.Google’s (2019) data sampling thresholds: Ad-hoc queries of your data are subject to the following general thresholds for sampling: [Google] Analytics (...) -- Analytics Tips, Development

  On considère qu'un auteur sans mot de passe ne peut pas se loger, par exemple parce qu'il ne sert qu'à signer des articles (mais n'est pas une vraie personne qui se connecte au site). Mais c'est quelque part pas très cohérent, car on ne peut pas supprimer un mot de passe sur un compte existant… Il faut juste être sûr que personne ne pourrait profiter de cette modif pour venir détourner un compte, avec les différents cas moisis (login vide, email vide etc).

  Ah ok, dans ce cas ça peut faire le job en attendant. Un souci avec le code généré par contre : si HTML5 est activé, les ancres nommées avec un attribut name sont dépréciées (), il faut utiliser des ids. Mais amha l'ajout de l'attribut id devrait être direct dans le core, sans avoir de plugin a activer. L'ajout d'une icône/lien peut être déporté dans un plugin peut-être, mais ça ne mange pas de pain de l'avoir dans le core aussi je trouve (si c'est optionnel).

  How to stream with ffmpeg via http protocol - Boehmi Newest 'ffmpeg' Questions - Stack Overflow
  I'm currently doing a stream that is supposed to display correctly within Flowplayer. First I send it to another PC via RTP. Here, I also checked with VLC that the codec etc. arrive correctly, which they do. Now I want to expose this stream to Flowplayer as a file, so it can be displayed, via something I used in VLC: http://localhost:8080/test.mp4 for example. The full line I got is: ffmpeg -i input -f mp4 http://localhost:8080/test.mp4 However, no matter how I try to do this, I only get an input/output error.

  Why does FFMPEG report the wrong duration? - Adrian Lynch Newest 'ffmpeg' Questions - Stack Overflow
  I have an oldish build of FFmpeg that I can't easily change. We use FFmpeg to find the duration of video and sound files. So far it has been working wonderfully. Recently on an uploaded file, FFmpeg has reported a 30 second file as being 5 minutes 30 seconds in length. Could it be something wrong with the file rather than FFmpeg? If I use FFmpeg to convert to another file, the duration is restored. In case it matters, ffmpeg -i 'path to the file' produces: FFmpeg version Sherpya-r15618, Copyright (c) 2000-2008 Fabrice Bellard, et al. libavutil 49.11. 0 / 49.11. 0 libavcodec 52. 0. 0 (...)

Couting packets might have worked for CBR streams (when muxrate was specified) but it only took into account the packets of a service (or the packets of the PCR stream lately), so even that was problematic for multi program streams. The new code works on actual timestamps for both CBR and VBR streams. For VBR streams the behaviour of the old code is simulated by selecting a PCR interval which is the highest multiple of the frame duration but still less than 100 ms. (...)

This patch solves this problem and selects a stream to become PCR for each service, preferably the video stream. This patch also moves pcr calculation attributes to MpegTSWriteStream from MpegTSService. PCR is a per-stream and not per-service thing, so it was misleading to refer to it as something that is per-service. Also remove *service from MpegTSWriteStream (...)

  I currently used the following command to make a video out of some 200 images, from here, this forces the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps, and from here, when outputting H.264, adding -vf format=yuv420p or -pix_fmt yuv420p will ensure compatibility so crappy players can decode the video. : ffmpeg -r 1 -i img%03d.png -r 24 output.mp4 -pix_fmt yuv420p Now I thought this will simply take the frames and stack them one after another.

  file1.wav is 25 minutes long. file2.wav is 20 seconds long. File2.wav delays to the end of the file1.wav and the two are "amixed" together. The delay works perfect and overlays into the correct location at the end of the 25 minute file1.wav file. My problem is the blending of the two clips together -- I believe the dropout_transition (even though it's set to 0) still creates an audible undesireable "dip" before and after file2.wav overlays onto file1.wav. Is there a way to ensure that no "dips" happen at all? The two clips are well-balanced with either using mixing software so I don't (...)

  cbs_mpeg2: Fix parsing the last unit There is one way to find out if avpriv_find_start_code has found a start code or not: One has to check whether the state variable contains a start code, i.e. whether the three most significant bytes are 0x00 00 01. Checking for whether the return value is the end of the designated buffer is not enough: If the last four bytes constitute a start code, the return value is also the end of the buffer.

The return value of avpriv_find_start_code points to the byte after the byte containing the start code identifier (or to the byte after the last byte of the fragment's data if no start code was found), but cbs_mpeg2_split_fragment needs to work with the pointer to the byte containing the start code identifier; it already did this, but in a clumsy way.

  The most efficient way to generate mp4 video containing looped boomerang-alike video file? - B. Palka Newest 'ffmpeg' Questions - Stack Overflow
  I've developed an Android app that allows user to create boomerang-alike mp4 video. This video consists of 10 still images being played back and forth quite fast. I know that such video (boomerang effect) can be easily looped from single video file while playing it, but I really need to create a mp4 video that would essentially contain already prepared boomerang video. The output video can be downloaded and played by user on any external player (over which obviously I don't have any control). For that purpose currently I create a video from images in a loop. The loop starts from 1st (...)

  Handling executables dependency on github - Max Paython Newest 'ffmpeg' Questions - Stack Overflow
  I am currently building an open-source project with Python for educational purposes, and I am going to add it on Github. It uses ffmpeg library as 64-bit compiled exe (I am on windows), by calling the executable with command line arguments within the code. My question is that, how to handle the situation of other people try to use my code (let's say customers, even there are none). Because they would also need the ffmpeg executable. Including ffmpeg executable to Github repo (Seems wrong, also would fail on multi-platform). Add a dependency control in the beginning of code, informing the (...)

  avcodec/mips: [loongson] refine process of setting block as 0 in h264dsp_mmi. - Shiyou Yin git.videolan.org Git - ffmpeg.git/rss log
  avcodec/mips: [loongson] refine process of setting block as 0 in h264dsp_mmi. In function ff_h264_add_pixels4_8_mmi, there is no need to reset '%[ftmp0]' to 0, because it's value has never changed since the start of the asm block. This patch remove the redundant 'xor' and set src to zero once it was loaded. In function ff_h264_idct_add_8_mmi, 'block' is seted to zero twice. This patch removed the first setting zero operation and move the second one after the load operation of block. In function ff_h264_idct8_add_8_mmi, 'block' is seted to zero twice (...)

  How to convert an ffmpeg texture to Open GL texture without copying to CPU memory - Lucas Zanella Newest 'ffmpeg' Questions - Stack Overflow
  This ffmpeg example demonstrates how to do hardware decoding: https://github.com/FFmpeg/FFmpeg/blob/release/4.2/doc/examples/hw_decode.c At line 109 it does this: /* retrieve data from GPU to CPU */ if ((ret = av_hwframe_transfer_data(sw_frame, frame, 0)) I want to avoid this because it takes time. Therefore, I need a way to reuse that decoded video, which is in GPU memory, to redo color conversion. How to transform the decoded texture in GPU memory to texture in Open GL without getting it back to CPU memory like in the code above? If the above is not possible, how to do color (...) -- https://github.com/FFmpeg/FFmpeg/blob/release/4.2/doc/examples/hw_decode.c
