link error Xcode libx264.a ARM
19 novembre 2013, par user1558688I'm trying to build libx264.a to run on my iphone 4s ( running iOS 6.1.3 )
I'm building it using the MACOSX 10.9 Terminal application :
CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang ./configure
--host=arm-apple-darwin
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk

--extra-ldflags="-L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/system -arch armv7"

So far, so good.
On my Xcode (Version 5.0.2 (5A3005)) application I set :
1) Build Settings -> Header Search Path -> x264 parent directory (../x264 )

{
x264_param_t x264param;
x264_param_default(&x264param);
// Override point for customization after application launch.
return YES;
}
...When i try to run it on the device I get the error :
Undefined symbols for architecture armv7:

Using ffmpeg and ffserver to create a 2x1 live stream fails with unconnected output error
31 janvier 2021, par weevilknievelI want to combine 2 RTSP streams (CCTV cameras) into a horizontal 2x1 strip and convert to webm for use in a HTML5 webpage.



I am able to convert the streams into an mpeg or avi file easily, but as soon as I try to post it to ffserver ffm feed, I hit a wall.



Here is my working ffmpeg command which writes out to a file :



ffmpeg -rtsp_transport tcp -thread_queue_size 12 -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=1&stream=1.sdp" -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=2&stream=1.sdp" -filter_complex "[0:v][1:v] hstack=inputs=2 [v]" -map "[v]" -r 30 output.mpg



It seems the ffmpeg process is outputting two streams and one of them is MPEG ? In the above command I had to put a frame rate "-r 30" into the command otherwise I got an error which said that MPEG 1/2 did not support a framerate of 5/1 ??



As soon as I try and stream to ffserver, I get an error :



ffmpeg -rtsp_transport tcp -thread_queue_size 12 -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=1&stream=1.sdp" -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=2&stream=1.sdp" -filter_complex "[0:v][1:v] hstack=inputs=2 [v]" -map "[v]" -r 30 http://localhost:8090/feed5.ffm



The error I get is "Filter hstack has an unconnected output" :
