HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.

Android : FFMpeg video creation crashes with no exception in lower APIs (18 in my case)
28 avril 2019, par Diego PerezI have an app that uses FFMpeg for video creation (these next lines are the relevant build.gradle plugin files) :
//writingminds
api 'com.writingminds:FFmpegAndroid:0.3.2'
//JavaCV video
api group: 'org.bytedeco', name: 'javacv', version: '1.4.4'
api group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.0.1-1.4.4', classifier: 'android-arm'
api group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '4.1-1.4.4', classifier: 'android-arm'And my app is working (and creating video) just fine in my phone with a newer Android 8 version but I’m having weird problems in my old API 18 tablet (where, as a note, I had to install multidex).
These next lines are the main part of FFMpeg video creation, where binaries are loaded, and, in fact, binaries load are where app crashes in my old tablet in the line "ffmpeg.loadBinary(new LoadBinaryResponseHandler()..."
As you can see, I have a try/catch where the app crashes, but it crashes with no exception, as catch blocks are never hit.
public static String recordVideo(JSONObject objJSON) {
String strReturn = Enum.Result.OK;
try {
fileName = objJSON.has("file_name") ? String.valueOf(objJSON.getString("file_name")) : "";
videoPath = objJSON.has("video_path") ? String.valueOf(objJSON.getString("video_path")) : "";
} catch (JSONException e) {
ExceptionHandler.logException(e);
}
FFmpeg ffmpeg = FFmpeg.getInstance(ApplicationContext.get());
try {
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {}
@Override
public void onFailure() {}
@Override
public void onSuccess() {}
@Override
public void onFinish() {}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
} catch (Exception e) {
}
...These next lines are the relevant part of the LogCat, but I cannot figure out where the problem resides, maybe an out of memory problem ?
Any help will be much appreciated.

</unknown>Edit 1 :
Still investigating and entered FFmpeg.java to the method loadBinary while debugging, which code I’ll paste below and the line making the crash is switch (CpuArchHelper.getCpuArch())
@Override
public void loadBinary(FFmpegLoadBinaryResponseHandler ffmpegLoadBinaryResponseHandler) throws FFmpegNotSupportedException
String cpuArchNameFromAssets = null ;
switch (CpuArchHelper.getCpuArch())
case x86 :
Log.i("Loading FFmpeg for x86 CPU") ;
cpuArchNameFromAssets = "x86" ;
break ;
case ARMv7 :
Log.i("Loading FFmpeg for armv7 CPU") ;
cpuArchNameFromAssets = "armeabi-v7a" ;
break ;
case NONE :
throw new FFmpegNotSupportedException("Device not supported") ;
if (!TextUtils.isEmpty(cpuArchNameFromAssets)) {
ffmpegLoadLibraryAsyncTask = new FFmpegLoadLibraryAsyncTask(context, cpuArchNameFromAssets, ffmpegLoadBinaryResponseHandler);
ffmpegLoadLibraryAsyncTask.execute();
} else {
throw new FFmpegNotSupportedException("Device not supported");
}I’ll keep on investigating...
Edit 2 :
Further debugging has just lead me to the exact line where app crashes, and it’s CpuArchHelper.java from FFmpeg library :
The line causing the crash is the next :
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();and I cannot even go inside cpuArchFromJNI() with F7 as it just crashes.
package com.github.hiteshsondhi88.libffmpeg;
import android.os.Build;
class CpuArchHelper {
static CpuArch getCpuArch() {
Log.d("Build.CPU_ABI : " + Build.CPU_ABI);
// check if device is x86 or x86_64
if (Build.CPU_ABI.equals(getx86CpuAbi()) || Build.CPU_ABI.equals(getx86_64CpuAbi())) {
return CpuArch.x86;
} else {
// check if device is armeabi
if (Build.CPU_ABI.equals(getArmeabiv7CpuAbi())) {
ArmArchHelper cpuNativeArchHelper = new ArmArchHelper();
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();
// check if device is arm v7
if (cpuNativeArchHelper.isARM_v7_CPU(archInfo)) {
// check if device is neon
return CpuArch.ARMv7;
}
// check if device is arm64 which is supported by ARMV7
} else if (Build.CPU_ABI.equals(getArm64CpuAbi())) {
return CpuArch.ARMv7;
}
}
return CpuArch.NONE;
}
static String getx86CpuAbi() {
return "x86";
}
static String getx86_64CpuAbi() {
return "x86_64";
}
static String getArm64CpuAbi() {
return "arm64-v8a";
}
static String getArmeabiv7CpuAbi() {
return "armeabi-v7a";
}
}This is ArmArchHelper.java class :
package com.github.hiteshsondhi88.libffmpeg;
class ArmArchHelper {
static {
System.loadLibrary("ARM_ARCH");
}
native String cpuArchFromJNI();
boolean isARM_v7_CPU(String cpuInfoString) {
return cpuInfoString.contains("v7");
}
boolean isNeonSupported(String cpuInfoString) {
// check cpu arch for loading correct ffmpeg lib
return cpuInfoString.contains("-neon");
}

Android : FFMpeg video creation crashes with no exception when loading binaries in lower APIs (18 in my case)
29 avril 2019, par Diego PerezI have an app that uses FFMpeg for video creation (these next lines are the relevant build.gradle plugin files) :
//writingminds
api 'com.writingminds:FFmpegAndroid:0.3.2'
//JavaCV video
api group: 'org.bytedeco', name: 'javacv', version: '1.4.4'
api group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.0.1-1.4.4', classifier: 'android-arm'
api group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '4.1-1.4.4', classifier: 'android-arm'And my app is working (and creating video) just fine in my phone with a newer Android 8 version but I’m having weird problems in my old API 18 tablet (where, as a note, I had to install multidex).
These next lines are the main part of FFMpeg video creation, where binaries are loaded, and, in fact, binaries load are where app crashes in my old tablet in the line "ffmpeg.loadBinary(new LoadBinaryResponseHandler()..."

} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
} catch (Exception e) {
}
...These next lines are the relevant part of the LogCat, but I cannot figure out where the problem resides, maybe an out of memory problem ?
Any help will be much appreciated.

</unknown>Edit 1 :
Still investigating and entered FFmpeg.java to the method loadBinary while debugging, which code I’ll paste below and the line making the crash is switch (CpuArchHelper.getCpuArch())
@Override
public void loadBinary(FFmpegLoadBinaryResponseHandler ffmpegLoadBinaryResponseHandler) throws FFmpegNotSupportedException
String cpuArchNameFromAssets = null ;
switch (CpuArchHelper.getCpuArch())
case x86 :
Log.i("Loading FFmpeg for x86 CPU") ;
cpuArchNameFromAssets = "x86" ;
break ;
case ARMv7 :
Log.i("Loading FFmpeg for armv7 CPU") ;
cpuArchNameFromAssets = "armeabi-v7a" ;
break ;
case NONE :
throw new FFmpegNotSupportedException("Device not supported") ;
if (!TextUtils.isEmpty(cpuArchNameFromAssets)) {
ffmpegLoadLibraryAsyncTask = new FFmpegLoadLibraryAsyncTask(context, cpuArchNameFromAssets, ffmpegLoadBinaryResponseHandler);
ffmpegLoadLibraryAsyncTask.execute();
} else {
throw new FFmpegNotSupportedException("Device not supported");
}I’ll keep on investigating...
Edit 2 :
Further debugging has just lead me to the exact line where app crashes, and it’s CpuArchHelper.java from FFmpeg library :
The line causing the crash is the next :
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();and I cannot even go inside cpuArchFromJNI() with F7 as it just crashes.
package com.github.hiteshsondhi88.libffmpeg;
import android.os.Build;
class CpuArchHelper {
static CpuArch getCpuArch() {
Log.d("Build.CPU_ABI : " + Build.CPU_ABI);
// check if device is x86 or x86_64
if (Build.CPU_ABI.equals(getx86CpuAbi()) || Build.CPU_ABI.equals(getx86_64CpuAbi())) {
return CpuArch.x86;
} else {
// check if device is armeabi
if (Build.CPU_ABI.equals(getArmeabiv7CpuAbi())) {
ArmArchHelper cpuNativeArchHelper = new ArmArchHelper();
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();
// check if device is arm v7
if (cpuNativeArchHelper.isARM_v7_CPU(archInfo)) {
// check if device is neon
return CpuArch.ARMv7;
}
// check if device is arm64 which is supported by ARMV7
} else if (Build.CPU_ABI.equals(getArm64CpuAbi())) {
return CpuArch.ARMv7;
}
}
return CpuArch.NONE;
}
static String getx86CpuAbi() {
return "x86";
}
static String getx86_64CpuAbi() {
return "x86_64";
}
static String getArm64CpuAbi() {
return "arm64-v8a";
}
static String getArmeabiv7CpuAbi() {
return "armeabi-v7a";
}
}This is ArmArchHelper.java class :
package com.github.hiteshsondhi88.libffmpeg;
class ArmArchHelper {
static {
System.loadLibrary("ARM_ARCH");
}
native String cpuArchFromJNI();
boolean isARM_v7_CPU(String cpuInfoString) {
return cpuInfoString.contains("v7");
}
boolean isNeonSupported(String cpuInfoString) {
// check cpu arch for loading correct ffmpeg lib
return cpuInfoString.contains("-neon");
}

Android : FFMpeg (video creation) crashes with no exception when loading binaries in lower APIs (18 in my case) but works in newer ones
6 mai 2019, par Diego PerezI have an app that uses FFMpeg for video creation (these next lines are the relevant build.gradle plugin files) :
//writingminds
api 'com.writingminds:FFmpegAndroid:0.3.2'
//JavaCV video
api group: 'org.bytedeco', name: 'javacv', version: '1.4.4'
api group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.0.1-1.4.4', classifier: 'android-arm'
api group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '4.1-1.4.4', classifier: 'android-arm'And my app is working (and creating video) just fine in my phone with a newer Android 8 version but I’m having weird problems in my old API 18 tablet (where, as a note, I had to install multidex).
These next lines are the main part of FFMpeg video creation, where binaries are loaded, and, in fact, binaries load are where app crashes in my tablet in the line "
ffmpeg.loadBinary(new LoadBinaryResponseHandler()..."As you can see, I have a try/catch where the app crashes, but it crashes with no aparent exception, as catch blocks are never hit.
public static String recordVideo(JSONObject objJSON) {
String strReturn = Enum.Result.OK;
try {
fileName = objJSON.has("file_name") ? String.valueOf(objJSON.getString("file_name")) : "";
videoPath = objJSON.has("video_path") ? String.valueOf(objJSON.getString("video_path")) : "";
} catch (JSONException e) {
ExceptionHandler.logException(e);
}
FFmpeg ffmpeg = FFmpeg.getInstance(ApplicationContext.get());
try {
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {}
@Override
public void onFailure() {}
@Override
public void onSuccess() {}
@Override
public void onFinish() {}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
} catch (Exception e) {
}
...These next lines are the relevant part of the LogCat, but I cannot figure out where the problem resides, maybe an out of memory problem ?
Any help will be much appreciated.

</unknown>Edit 1 :
Still investigating and entered FFmpeg.java to the method loadBinary while debugging, which code I’ll paste below and the line making the crash is switch (CpuArchHelper.getCpuArch())
@Override
public void loadBinary(FFmpegLoadBinaryResponseHandler ffmpegLoadBinaryResponseHandler) throws FFmpegNotSupportedException {
String cpuArchNameFromAssets = null;
switch (CpuArchHelper.getCpuArch()) {
case x86:
Log.i("Loading FFmpeg for x86 CPU");
cpuArchNameFromAssets = "x86";
break;
case ARMv7:
Log.i("Loading FFmpeg for armv7 CPU");
cpuArchNameFromAssets = "armeabi-v7a";
break;
case NONE:
throw new FFmpegNotSupportedException("Device not supported");
}
if (!TextUtils.isEmpty(cpuArchNameFromAssets)) {
ffmpegLoadLibraryAsyncTask = new FFmpegLoadLibraryAsyncTask(context, cpuArchNameFromAssets, ffmpegLoadBinaryResponseHandler);
ffmpegLoadLibraryAsyncTask.execute();
} else {
throw new FFmpegNotSupportedException("Device not supported");
}
}I’ll keep on investigating...
Edit 2 :
Further debugging has just lead me to the exact line where app crashes, and it’s CpuArchHelper.java from FFmpeg library :
The line causing the crash is the next :
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();and I cannot even go inside cpuArchFromJNI() with F7 as it just crashes.
package com.github.hiteshsondhi88.libffmpeg;
import android.os.Build;
class CpuArchHelper {
static CpuArch getCpuArch() {
Log.d("Build.CPU_ABI : " + Build.CPU_ABI);
// check if device is x86 or x86_64
if (Build.CPU_ABI.equals(getx86CpuAbi()) || Build.CPU_ABI.equals(getx86_64CpuAbi())) {
return CpuArch.x86;
} else {
// check if device is armeabi
if (Build.CPU_ABI.equals(getArmeabiv7CpuAbi())) {
ArmArchHelper cpuNativeArchHelper = new ArmArchHelper();
String archInfo = cpuNativeArchHelper.cpuArchFromJNI();
// check if device is arm v7
if (cpuNativeArchHelper.isARM_v7_CPU(archInfo)) {
// check if device is neon
return CpuArch.ARMv7;
}
// check if device is arm64 which is supported by ARMV7
} else if (Build.CPU_ABI.equals(getArm64CpuAbi())) {
return CpuArch.ARMv7;
}
}
return CpuArch.NONE;
}
static String getx86CpuAbi() {
return "x86";
}
static String getx86_64CpuAbi() {
return "x86_64";
}
static String getArm64CpuAbi() {
return "arm64-v8a";
}
static String getArmeabiv7CpuAbi() {
return "armeabi-v7a";
}
}This is ArmArchHelper.java class :
package com.github.hiteshsondhi88.libffmpeg;
class ArmArchHelper {
static {
System.loadLibrary("ARM_ARCH");
}
native String cpuArchFromJNI();
boolean isARM_v7_CPU(String cpuInfoString) {
return cpuInfoString.contains("v7");
}
boolean isNeonSupported(String cpuInfoString) {
// check cpu arch for loading correct ffmpeg lib
return cpuInfoString.contains("-neon");
}
}Edit 3 :
Reading carefully LogCat I’ve noticed there is a TransactionTooLarge Exception :
04-28 21:44:46.103 450-13973/? W/ActivityManager: Exception thrown during pause

Edit 3 :
As a note, I’ve tried in an old Android 4.2.2 (API 17) phone I also own and it’s working just fine, the video is generated without crashing.
