Flutter ios ，you convert wav to amr，then use 'FFprobeKit' print amr media infomation, you will know what i say |
|
The right file you use 'FFprobeKit' print media infomation, you can get all media infomation, but the amr file which conver from wav used FFmpeg can not get any media infomation |
|
This url is wav (http://media.yilianjiaoyou.com/11/250f2ce0bed29ca157867692abf3c3bc.wav) |

We have lots of issues reported in this project, where API methods are not used correctly. Because of that, we expect users to share their source code. To make sure that API methods are used in the right way and the issue is worth spending time on. We have to do this since we don't have unlimited time and we cannot guess what developers are doing in their apps. This is clearly explained in #215. I don't see any source code here. So, there is nothing we can do. |

I meet the same problem in Android. 将任何格式的音文件转换成“amr”格式，可以执行成功，但生成的文件播放失败，AudioPlayer无法读取，将该文件导出到电脑上，也无法播放，显示文件有问题。 dependence:
some logic code: private const val SPACE = " "
/** 获取音频格式转换命令 */ // FFmpegOperateManager.getAudioFormatConvertCommand 方法
fun getAudioFormatConvertCommand(fromPath: String?, toPath: String?): String? {
val fromFormat = RecordSupportedHelper.getAudioFileFormat(fromPath) ?: return null
val toFormat = RecordSupportedHelper.getAudioFileFormat(toPath) ?: return null
if (fromFormat == toFormat) { return null }
val commandBuilder = StringBuilder()
commandBuilder.append("-hide_banner -y")
// 输入文件前的参数组织
when (fromFormat) {
RecordAudioFormat.PCM -> {
commandBuilder.append(SPACE).append("-f s16be -acodec pcm_s16le")
}
else -> { /** do nothing */ }
}
// 输入文件
commandBuilder.append(SPACE).append("-i").append(SPACE).append(fromPath)
// 输出文件前的参数组织
when (toFormat) {
RecordAudioFormat.PCM -> {
commandBuilder.append(SPACE).append("-f s16be -ar 16000 -ac 1 -acodec pcm_s16le")
}
RecordAudioFormat.AMR -> {
commandBuilder.append(SPACE).append("-ar 8000 -ac 1")
}
else -> {
commandBuilder.append(SPACE).append("-ar 16000 -ac 1")
}
}
// 输入文件
commandBuilder.append(SPACE).append(toPath)
return commandBuilder.toString()
}
// FFmpegOperateManager.executeFFmpegCommand 方法
/** 执行ffmpeg命令 */
fun executeFFmpegCommand(command: String?, complete: (Boolean) -> Unit) {
if (command.isNullOrEmpty()) { complete(false); return }
FFmpegKit.executeAsync(command,
{ session ->
if (ReturnCode.isSuccess(session?.returnCode)) {
mHandler.post { complete(true) }
} else {
mHandler.post { complete(false) }
}
},
{ log ->
Trace.e(log.message)
},
{ statistic ->
Trace.e(statistic.toString())
}
)
}
// 这是调用的地方
fun startToFormatAudioFile(audioPath: String?, toFormat: RecordAudioFormat): Boolean {
if (audioPath.isNullOrEmpty()) { return false }
// 获取目标文件
val destFile = RecordMediaNameHelper.generateMediaFile(audioPath,
RecordStoreFileManager.getStoreAudioCommonDir(), toFormat, RecordFuncType.AUDIO_FORMAT)
if (destFile == null) { return false }
// 获取ffmpeg命令
val command = FFmpegOperateManager.getAudioFormatConvertCommand(audioPath, destFile.absolutePath)
// 执行命令
FFmpegOperateManager.executeFFmpegCommand(command) {
if (it) { saveInDatabaseAfterFFmpegOperate(destFile) } else {
mFormatState.postValue(false)
}
}
return true
}
下面是执行一次示例的日志
这是使用FFmpegKit转换后的文件跟 正常转换后的文件数据的一个对比，好像少了一个字节数据 我使用下面的方法间接解决了这个问题，希望可以尽快修改好。 private val sAmrFileHeaderArray = byteArrayOf(35, 33, 65, 77, 82, 10)
private fun byteArrayCompare(src: ByteArray, another: ByteArray): Pair<Boolean, Int> {
if (src.size != another.size) return Pair(false, 0)
for (i in src.indices) {
if (src[i] != another[i]) {
return Pair(false, i)
}
}
return Pair(true, 0)
}
fun repairFFmpegKitAmrFile(amrFile: File?) {
if (amrFile == null || !amrFile.isFile) { return }
if (!amrFile.extension.equals("amr", true)) {
return
}
val tempFileName = "temp_${amrFile.name}"
val tempFile = File(amrFile.parent, tempFileName)
// 检查amr文件格式是否正确
var inputStream: FileInputStream? = null
var outputStream: OutputStream? = null
try {
inputStream = FileInputStream(amrFile)
val byteArray = ByteArray(sAmrFileHeaderArray.size)
inputStream.read(byteArray)
val (same, index) = byteArrayCompare(byteArray, sAmrFileHeaderArray)
if (same) { return }
val dataBuffer = ByteArray(8 * 1024)
FileUtils.createOrExistsFile(tempFile)
outputStream = BufferedOutputStream(FileOutputStream(tempFile))
// write header
outputStream.write(sAmrFileHeaderArray)
outputStream.write(byteArray, index, byteArray.size - index)
var readSize: Int
while (inputStream.read(dataBuffer).also { readSize = it } != -1) {
outputStream.write(dataBuffer, 0, readSize)
}
outputStream.flush()
// 将原文件删除
FileUtils.delete(amrFile)
FileUtils.rename(tempFile, amrFile.name)
} catch (t: Throwable) {
return
} finally {
closeStream(inputStream)
closeStream(outputStream)
}

Description
I convert wav to amr, the 'session.getReturnCode()' is 'isValueSuccess' ,but i get media formation from 'FFprobeKit',the result is "Invalid data found when processing input",i can get nothing about the amr media formation. I try to print mp3,wav,mp4,that all is right ,so i think is the problem with 'libopencore-amrnb'.
Expected behavior
i want convert success,and amr can be played success
Current behavior
convert success,but file is unusefull
