Random segmentation fault with avcodec_encode_video2()
10 août 2015, par Seba Arriagadathis is my first question so i hope i did it correctly. If not, please let me know to fix it.
I’m trying to convert a short (10 secs) mp4 video file into a gif using ffmpeg libraries (I’m pretty new using ffmpeg). The program works pretty well converting to gif, but some times it randomly crash.
This is the version of the ffmpeg libraries I’m using :
libavutil 54. 27.100
libavcodec 56. 41.100
libavformat 56. 36.100
libavdevice 56. 4.100
libavfilter 5. 16.101
libavresample 2. 1. 0
libswscale 3. 1.101
libswresample 1. 2.100
libpostproc 53. 3.100I’m using a 1920x1080p video, so in order to generate the gif I’m doing a pixel format convertion, from
AV_PIX_FMT_YUV420PtoAV_PIX_FMT_RGB8with a resizing from the initial resolution to 432x240p.Here is the code :
int VideoManager::loadVideo(QString filename, bool showInfo)

}I know there are a lot of memory leaks. I deleted/commented most of the free functions intentionality because i thought that was the problem.
I’m using Qtcreator, so when i debug the programs this is the output :
Level Function Line
0 av_image_copy 303
1 frame_copy_video 650
2 av_frame_copy 687
3 av_frame_ref 384
4 gif_encode_frame 307
5 avcodec_encode_video2 2191
6 VideoManager::encodeAndWriteFrame 813
7 VideoManager::generateGif 375
8 qMain 31
9 WinMain*16 112
10 mainI’ve checked if there is a specific frame the program crash at, but it’s a random frame too.
Any idea of what i’m doing wrong ? Any help would be very appreciated.
EDIT :
After a few days of pain, suffering and frustation I decided to write the whole code from scratch. Both times i started from this example and modified it in order to works as I described before. And it works perfectly now :D ! The only error i could find in the old code (posted before) is when i try to access to the video stream in the output file I used
videoStreamIndex, but that index is from the video stream in the input file. Some times it could be the same index and some times not. But it doesn’t explain why it crashed randomly. If that was the reason of the crash, it should crash every time i ran the code with the same video. So probably, there are more errors in that code.
Notice that i’ve not tested if fixing that error in the code above actually solve the crashing problems. -
How to merge two videos using FFMpeg PHP
7 août 2015, par Vikascurrently i am working on a project where i need to merge the two videos using ffmpeg and php. I need to make two video play same time and on stop should stop at same time and if one video stop’s than other should also pause. I have searched a lot but didn’t find any thing, hope anyone can help me.

ffmpeg command failed
25 octobre 2015, par Asad kamranI am experimenting FFMPEG command to convert any video format to mp4.
Server admin execute the below command created by me and show me the errors :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgThis is error :
[aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
codecs are not enabled, add ’-strict -2’ if you want to use it.how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.
my ffmpeg and server are as follow :

I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :New command :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgAfter executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
