• ffmpeg adding 6 secs of black frames in the beginning of a file

  7 août 2014, par user3842039

  Trying to convert a .mov file (h264 and pcm) generated in Mpegstreamclip (MacOS) and the result is strangely out of sync with around 6 seconds of black frames at the beginning. I have tried many differente audio and video codec and the result is the same even with a -vcodec copy and -acodec copy. Below the return of ffmpeg (git version compiled today - 06/08/2014) :

• ffmpeg concatenation after using drawtext filter

  12 août 2016, par Sven Hoskens

  I’m fairly new to ffmpeg, but after a few days of searching on this issue, I’ve completely hit a brick wall. Any help would be appreciated.

  My use case : Our client wants to upload videos for multiple regions. Each video will be the same format, 1920x1080, mp4. For each region, they want to add a different image at the end of the video, for a few seconds. This image contains their logo, some additional info, and a variable code. They will enter this code alongside the uploaded video. The image stays the same, so is already present on the server.
  So basically, I have an input video, a video of an image, and a small code. I need to add this code to the video of the image (in a predefined position), and then I need to add the resulting video to the end of the input video. Once that is complete, I just need to output the video in 1920x1080 and in 1024x576.

  I have tried several things, but the concatenation step always fails with the manipulated video’s.

  Attempt 1

  In my first attempt, I used ffmpeg to create a video from an image, and add the text in the designated area.

  ffmpeg -y -f lavfi -i image.png -r 30 -t 10 -pix_fmt yuv420p -map 0:v -vf drawtext="fontfile=HelveticaNeue.dfont: text='GLNS/TEST/1234b': fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=7: x=179: y=805" imageVideo.mp4

  This command creates a .mp4 video of the correct size, with a duration of 10 seconds, and adds the text ’GLNS/TEST/1234b’ in the correct location.

  Next, I use the following command to concatenate the two videos. Both have the same resolution and codec.

  ffmpeg -f concat -safe 0 -i config.txt -vf scale=1920:1080 outputHD.mp4 -vf scale=1024:576 outputSD.mp4

  config.txt contains following :

  file my_input_file.mp4
  
  file ImageVideo.mp4

  This concatenation works with regular videos. However, when I use it with ImageVideo.mp4 (the one created by the first command) I get this error log :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f86dc924600] Auto-inserting h264_mp4toannexb bitstream filtereed=0.509x

  Error while decoding stream #0:1: Invalid data found when processing input
  
  
  
  #this goes on for a few hundred lines

  The resulting output is identical to the input video, but does not contain the desired image video at the end.

  Attempt 2

  Since the above attempt didn’t work, I tried concatenating a video I let our designer make of the image with Adobe After Effects. This video was also saved as a .mp4 with the H264 codec. If I concatenate the input video and this one, I get a correct result. However, as soon as I add the code in the designated area with this command :

  ffmpeg -i new_image_video.mp4 -vf drawtext="fontfile=HelveticaNeue.dfont: text='GLNS/TEST/1234b': fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=7: x=179: y=805" -c:v libx264 imageVideo.mp4

  I get this error :

  The resulting output is identical to the input video, but does not contain the desired image video at the end.

  One thing I have noticed : When I inspect the video files on mac (Get info) they always contain these lines at ’More info’ :

  Dimensions: 1920 x 1080
  
  Codecs: H.264, AAC
  
  Color profile: HD(1-1-1)
  
  Duration: 01:42
  
  Audio channels: 2
  
  Last opened: Today 11:02

  However, the video’s which pass through the drawtext filter have this :

  Dimensions: 1920 x 1080
  
  Codecs: AAC, H.264
  
  Duration: 00:10
  
  Audio channels: 2
  
  Last opened: Today 11:07

  As you can see, there is no color profile entry, and the codecs have switched places. I assume this is related to my issue, but I can’t seem to find a fix for it.

  PS : The application will run in a php environment (Symfony). I noticed the concat command wasn’t available in the Symfony bundle for ffmpeg, so I’m using the regular terminal commands. I’ll execute these using php.

  EDIT
  Attempt 3

  On advise of a coworker, I tried converting the video to .avi and reconverting to .mp4, in the hopes this would lose any corrupted or extra info included by the drawtext filter. This spits out a completely different error.

  Kia ora from the marketing team !

  Marketing team ? That’s right ! You haven’t heard from us in the past, but we’ve been working in the background to create a better experience for you, our dedicated Matomo community.

  Kia ora ? Well, that just means “hello” in Maori, we’re based in New Zealand you see.

  The Matomo marketing team has some really exciting projects in the works we wanted to share with you, but first, there’s someone I want to introduce :

  Meet Joselyn from the Matomo Marketing team

  Meet Joselyn, one half of the Matomo marketing team and our Digital Marketing and Communications Specialist. Joselyn has come on board to help us communicate more frequently and effectively as we continue our mission to be the #1 free open source analytics platform in the world. Please take it away, Joselyn !

  “Hi everyone ! The team here at Matomo have been doing an incredible job passionately driving the cause for user privacy and data ownership and uniting that with a love for digital analytics. It’s exciting being a part of a team unafraid to push on with their hearts on their sleeves and their values at the forefront of everything they do. I hope to bring to light all the fantastic things happening in our world of web analytics as well as across the globe.

  

  Our online world is fascinating when we think about what we can achieve with analytics, but there’s room to improve. We see newer technologies, but old ways of working which don’t take into account a person’s safety online. So we hope to champion a new future which looks set to be much more meaningful. Ensuring you get the best experience, but also feel protected with the knowledge that we get it. Your data and privacy isn’t for sale.

  I also hear you guys, the community, have followed Matomo since the beginning, which is wonderful ! I hope you’ll be able to join us as we grow and learn. We’ve got so many thrilling things to share with you. The highs, the lows and everything in between. Cheers !”

  Thanks Joselyn ! On top of working to engage the community and new users, Joselyn will also be keeping the rest of the Matomo team on our toes getting the inside scoop on what’s happening within the Development and Support teams ; as well as giving you behind-the-scenes access to what’s going on here at Matomo. We have a big vision and with so many things happening right now, we want to get you involved as much as possible.

  It may sound a bit clichéd but I’m saying it anyway – without your help, Matomo wouldn’t be here today.

  Help us choose a logo

  So first of all, we want you to say thank you and second we’d be delighted if you could help choose our new logo ! As you may already know, we changed our name from Piwik to Matomo at the start of the year. Though it was fun using a cool font (Aileron Heavy btw) as a quick fix for our name change, it was a temporary solution. The Matomo team has been involved in the direction of creating a new logo, but now we’re stumped ! We have three different concepts to choose from so please help us out !

  A new website for Matomo.org !

  Other exciting marketing projects include a new website design (yay !) – to everyone gasping nervously…don’t worry, nothing in what we offer is changing. We are and always will be a freely accessible open source analytics platform, just wanted to quickly clear the air on that one !

  We also have some video projects in the works to make the Matomo experience better for everyone and there are even rumours a brand video that tells the Matomo story is on the way ;)

  What next ? With Joselyn on board and loads of exciting projects happening, it won’t be long until you hear from us again, so keep an eye out for our next update as we reveal the winning Matomo logo.

  Be sure to follow us on Facebook, Twitter and Github – we promise to be more active than what we have been !
