Android - 360 video metadata
11 mai 2017, par XysSo with ffmpeg I’ve concatenated two 360 videos into one. The problem is that I lost all the 360 video metadata in the final video (so it’s not recognized as a 360 video anymore). If I use exiftool on the final video, I lack those metadatas :
- Spherical : true
- Stitched : true
- Stitching Software : Spherical Metadata Tool
- Projection Type : equirectangular
I’ve tried to inject those metadatas with ffmpeg, like this for example :
ffmpeg -i -metadata Spherical="true" -codec copy
I don’t get any errors doing that, but exiftool still doesn’t show the metadatas.
I know Google has a Python script that does this well, here .
But I would like to inject metadatas in my app as well, any help would be much appreciated,
thanks !

Why does ffmpeg h264 decoder stop decoding when certain type of packets are coming in the input stream ?
28 juillet 2018, par jamsmeI used av_read_frame to get the AVPacket from encoded h264 file. But when this packet (00 00 01 05 94 5a 33 e7 4d 6b d7 ad 13 86 ff 47 83 93 31 f1 e3 0a) is in the input stream (h264 video) ffmpeg decoder stops decoding frames for any subsequent AVPackets.
But if I skip this packet to provide to the decoder the next AVPackets decode just fine. What is wrong with this packet ? Or what is wrong with the ffmpeg decoder ?Below is the test stream for reference.

Converting PNG images to MP4 in Jupyter
15 mars 2020, par Steve HThis has had me going round in circles for hours, so I’m hoping one of you kind gents can help.
I am trying to learn more about data science and have followed this course on creating a population pyramid (https://www.viralml.com/video-content.html?v=WmyYyOtZwzs). There were a few problems in the code, which I rectified, but one has eluded me.
I am trying to convert a collection of images in the format anim_%d.png to an mp4 file using the code :
ffmpeg -framerate 10 -i "anim_%d.png" -pix_fmt yuv420p out.mp4
However, I get an invalid syntax error.
I have also tried :
avconv -f image2 -i anim_%d.png -r 76 -s 800x600 foo.avi
then :
ffmpeg -r 10 -i "anim_%d.png" -pix_fmt yuv420p out.mp4
But they all give a syntax error.
I am using Jupyter, via Anaconda on a Windows machine with Python 3.
Any help would be greatly appreciated.
Thanks
Steve
