The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority
).
I found thepjsua_vid.o
is very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :

problem compiling ffmpeg for iFrameExtractor
11 septembre 2012, par Robin RyeI'm trying to compile the ffmpeg by using the make and build files in iFrameExtractor example. firstly i tried to follow the readme file on the github, which only says to run the
./build_universal
in ffmpeg folder. it did not worki then tried to follow the info in INSTALL without success. i then tried doing the stuff in INSTALL followed by the
./build_universal
which didn't work. All the *.a files that are imported to the project exists until the end of the build sequence. when the lipo commands in build_universal are run, which i guess concat the .a files for the different architectures(?). anyhow these leave the following errors :lipo: specifed architecture type (armv6) for file (armv6/libavcodec.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavdevice.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavformat.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavutil.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libswscale.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))i can get the project to compile for simulator if i only use
./build_armv7
but if i run the universal the .a files are removed in the end. and only using doesn't work to build for iphone 4 . -
Detect rotation angle and rotate final video using ffmpeg version 2.8
9 novembre 2017, par Hemant KumarI used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.
But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.
Here’r the commands I was using :
To check rotation angle :
ffprobe -of json -show_streams {$input} | grep rotate
below is my final command to convert a video to mp4
"ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution} -movflags faststart -metadata:s:v:0 rotate=0 {$output}";
"fix_video_orientation" function is given below. It detect the angle of rotation of the initial video and output optimal option for rotating the final video.
function fix_video_orientation($input){
$return= ", transpose=1 ";
$dd= exec("ffprobe -of json -show_streams {$input} | grep rotate");
if(!empty($dd)){
$dd=explode(":",$dd);
$rotate=str_replace(",","",str_replace('"',"",$dd[1]));
if($rotate=="90")return $return;
else if ($rotate=="180") return ", transpose=2,transpose=2 ";
else if($rotate == "270") return ", transpose=2 ";
}Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.
Now the ffprobe command is not returning rotation angle and so a portrait video if uploaded from iphone is showing as landscape on the website.
Output console of ffprobe command :
