是否可以通过 HEVC 解码器防止崩溃 "libc: Fatal signal 6 (SIGABRT), code -6 in tid 31891 (le.hevc.decoder)"
Is it possible to prevent the crash by HEVC decoder "libc: Fatal signal 6 (SIGABRT), code -6 in tid 31891 (le.hevc.decoder)"
我可以通过在 Android 设备上流式传输 H.265 视频来重现崩溃。所有相关代码都是 try-catch 块。是否有可能捕获异常并防止应用程序崩溃。跟踪不指向任何应用程序的代码。我怀疑它不是由任何特定语句引起的。

好像是下面code中的"CHECK_EQ(reInitDecoder(), (status_t)OK);"造成的：
// This is needed to handle CTS DecoderTest testCodecResetsHEVCWithoutSurface,
// which is not sending SPS/PPS after port reconfiguration and flush to the codec.
if (unsupportedDimensions && !mFlushNeeded) {
bool portWillReset = false;
handlePortSettingsChange(&portWillReset, s_dec_op.u4_pic_wd, s_dec_op.u4_pic_ht);
CHECK_EQ(reInitDecoder(), (status_t)OK);
setDecodeArgs(&s_dec_ip, &s_dec_op, inHeader, outHeader, timeStampIx);
ivdec_api_function(mCodecCtx, (void *)&s_dec_ip, (void *)&s_dec_op);
return;
}
有没有办法找出 Android 设备的 HEVC 解码器的不支持尺寸？
如果您正在寻求一种方法来获取编解码器不同参数的支持范围，您可以使用 MediaCodecInfo.VideoCapabilities
特别是，您可以通过调用
获得支持的高度和宽度
Range<Integer> getSupportedWidths()
Range<Integer> getSupportedHeights()
此外，您可以通过调用 getSupportedHeightsFor(int width) 和 getSupportedWidthsFor(int height) 获得给定宽度值支持的高度，反之亦然。您可以对帧率执行相同的操作...
最后，在你的情况下，你可以直接调用boolean isSizeSupported(int width, int height)
请查看此要点以获取给定 MedaCodec 的格式化功能值：

好像是下面code中的"CHECK_EQ(reInitDecoder(), (status_t)OK);"造成的：
// This is needed to handle CTS DecoderTest testCodecResetsHEVCWithoutSurface,
// which is not sending SPS/PPS after port reconfiguration and flush to the codec.
if (unsupportedDimensions && !mFlushNeeded) {
bool portWillReset = false;
handlePortSettingsChange(&portWillReset, s_dec_op.u4_pic_wd, s_dec_op.u4_pic_ht);
CHECK_EQ(reInitDecoder(), (status_t)OK);
setDecodeArgs(&s_dec_ip, &s_dec_op, inHeader, outHeader, timeStampIx);
ivdec_api_function(mCodecCtx, (void *)&s_dec_ip, (void *)&s_dec_op);
return;
}
有没有办法找出 Android 设备的 HEVC 解码器的不支持尺寸？
如果您正在寻求一种方法来获取编解码器不同参数的支持范围，您可以使用 MediaCodecInfo.VideoCapabilities
特别是，您可以通过调用
获得支持的高度和宽度Range<Integer> getSupportedWidths()
Range<Integer> getSupportedHeights()
此外，您可以通过调用 getSupportedHeightsFor(int width) 和 getSupportedWidthsFor(int height) 获得给定宽度值支持的高度，反之亦然。您可以对帧率执行相同的操作...
最后，在你的情况下，你可以直接调用boolean isSizeSupported(int width, int height)
请查看此要点以获取给定 MedaCodec 的格式化功能值： https://gist.github.com/aelqsimi/f773d63fd5f234df7892276e3b05e5f8
