Why JPEG image looks different in two videos ?
28 septembre 2015, par user606521I have two frames :
f1.jpg
f2.jpg
And I am creating two videos :
./ffmpeg -i ./f%d.jpg -r 30 -y m1.mp4 # both frames 1 and 2
./ffmpeg -i ./f2.jpg -r 30 -y m2.mp4 # only frame 2For some reason frame 2 looks different in these two videos
Frame 2 from m1.mp4 :
$ ./ffmpeg -i m1.mp4 out1_%d.jpg

It seems that frame 2 looks different when combined with frame 1 in a video. One thing I noticed that when dumping frames from m1.mp4 (two frames combined) there is a warning in ffmpeg output :
[swscaler @ 0x7f7f9a000600] deprecated pixel format used, make sure you did set range correctlyAlso two frame images have same dimmensions (980x100) and their format seems to be same :
$ file -b f1.jpg
JPEG image data, JFIF standard 1.01, comment: "CS=ITU601??"
$ file -b f2.jpg
JPEG image data, JFIF standard 1.01So why this is happening ? I am struggling with this issue for quite a long time - for some reason some JPEGs somehow are in different "format ?" than others and make mess in videos...

FFmpeg : generating H264 video in c++
13 octobre 2015, par EZEROFIVE EMDIm using ffmpeg library in windows with vs2012 to convert a series of images into Mp4 with H264 encoding. Im new to FFMPEG.
Below is my code. Everything went fine. Video is created.But i can play the video in vlc player only if i changed the extension to ".h264", also when i check for codec information it says "H264 - MPEG-4 AVC (part 10) (h264)". but when i checked the same for other mp4 videos which are downloaded from web. it says "H264 - MPEG-4" AVC (part 10) (avc1)". I dont understand where it went wrong. Also i searched a lot, some says like add SPS and PPS.
const uint8_t sps[] = { 0x00, 0x00, 0x00, 0x01, 0x67, 0x42, 0x00,
0x0a, 0xf8, 0x41, 0xa2 };
const uint8_t pps[] = { 0x00, 0x00, 0x00, 0x01, 0x68, 0xce,
0x38, 0x80 };So i added the above value to video file before i add the image stream. But no luck.
Can anyone help on this..Thanks in advance.const uint8_t sps[] = { 0x00, 0x00, 0x00, 0x01, 0x67, 0x42, 0x00,
0x0a, 0xf8, 0x41, 0xa2 };
const uint8_t pps[] = { 0x00, 0x00, 0x00, 0x01, 0x68, 0xce,

0x84, 0x21, 0xa0 };
const uint8_t macroblock_header[] = { 0x0d, 0x00 };
const uint8_t spspps[] = { 0x00, 0x00, 0x00, 0x01, 0x67, 0x42, 0x00, 0x0a, 0xf8, 0x41, 0xa2,
