Could not find tag for codec h264 in stream #0 (mp4)
18 août 2019, par TabsNotSpacesI’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.
I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.
ffmpeg 4.1.4

ffmpeg conversion of jpg to mp4 fails due to to jpg frames change
14 janvier 2019, par Sebastien DamayeI’m trying to compile a set of jpg (camera screenshots taken every 5 seconds) to a mp4. The ffmpeg command works fine but the resulting mp4 is missing some images. I noticed that the "holes" are created when the jpg "frames" is changing from 1 to 3 in the jpg sequence (see below result of
file
that showsframes 1
for the 1st jpg andframes 3
for the 2nd one) :$ file 20190110060113.jpg

ffmpeg
, it sows :ffmpeg -i 20190110060113.jpg -i 20190110060119.jpg

At least one output file must be specifiedBelow is the command I’m using to compile the mp4 from the jpg :
ffmpeg -r 25 -f image2 -s 1280x720 -i /data/camipjpg/%*.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p /data/camipmgpg/20190110.mp4
For the sake of curiosity, I investigated and noticed that the camera actually has 2 modes (day and night). Images taken during the night have
frames 1
while images taken on the "day" mode haveframes 3
.Is there a way ffmpeg can handle that kind of jpg changes to combine these different types of jpg ?
Here is the output :

OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error
19 avril, par user2262504I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.



It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec 'libx264'" error.



Anyone has ideas to solve this problem ?



More specifically :



- 

- anyone knows where and how OpenCV invoke ffmpeg API ?
- how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?
- will changes of default in ffmpeg be carried to libx264 ?









Errors :



1. Uising CV_FOURCC('H', '2', '6', '4')

Codes :



int main(int argc, char *argv[])
{
 VideoWriter outputVideo;
 bool fourcc_on = true; //switch on / off different error
 if (fourcc_on)
 outputVideo.open("outVideo.avi", CV_FOURCC('H', '2', '6', '4'), 25, Size(100, 100), true);
 else
 outputVideo.open("outVideo.avi", -1, 25, Size(100, 100), true);

 if (!outputVideo.isOpened())
 {
 cout << "Could not open the output video for write" << endl;
 return -1;
 }
 return 0;
