avcodec_find_encoder(AV_CODEC_ID_H264) returns null
28 février 2017, par Monjura RumiI am building an android application which will encode image captured from camera preview and later decode it. I am using ffmpeg library to encode and decode. To build static library with x264 I have used this tutorial. http://dl.dropbox.com/u/22605641/ffmpeg_android/main.html. As a source code of ffmpeg if I use the one downloaded from the link given in tutorial I can built it but can’t build library if i use source code downloaded from here git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg. I have built library in ubuntu and using it in windows 7 in Eclipse. As I need only h264 encoder and decoder I have used following code for ffmpeg, slightly modified from tutorial.

build_oneAfter building library I have been able to build android ndk. A little part of my JNI code is here.
JNIEXPORT jint JNICALL Java_com_example_testjava_TestjniActivity_initencoder(JNIEnv* env,jobject obj){
av_register_all();
avcodec_register_all();
codec = avcodec_find_encoder(AV_CODEC_ID_H264);
if (!codec) {
__android_log_write(ANDROID_LOG_INFO, "debug", "not found");
return -1;
}
.
.
.
}When I run my java source code that calls initencoder() I get -1 as return value and logcat prints "not found". That means avcodec_find_encoder() returns null and if condition is being ok. I don’t know what’s wrong. Why this function is returning null ? I have searched a lot but did not find any solution that could guide me to right direction. some says to use avcodec_init(). But ndk-build command fails and shows error saying undefined reference to ’avcodec_init()’. I have started with library build because I thought may be I am doing wrong from the first stage. Did I make any mistake in library building like not enabling things that I should ? Please help me here. This is kind of urgent for me.

Samsung S3 : 'Cannot play Video' on stock Video player
18 mars 2013, par d33pikaI am unable to play a mp4 video(H.264 Baseline, AAC) on Samsung S3, Android Version : 4.1.1, stock video player but plays on VLC. The same video plays on Galaxy Beam, Android Version : 2.3.6, stock Video Player. I want to figure out why it does not play on S3. I ran ffprobe and mediainfo on the fie :

Error FFmpeg in Android
19 novembre 2013, par MarkI'm using FrameGrabber to load a video from sdcard and perform some image processing operation. I followed the tutorial at JavaCV site to load javacc and ffmpeg.
Currently, to run the application, I'm using my tablet (Asus TF 101G with Android version 4.0.3) connected to my pc and it works fine. But if I try to run the same application in another device (e.g. Nexus with Android 4.1.2) I get these errors :02-01 16:51:54.687: E/AndroidRuntime(2839): FATAL EXCEPTION: main
