Можно ли предотвратить сбой с помощью декодера HEVC "libc: фатальный сигнал 6 (SIGABRT), код -6 в тид 31891 (le.hevc.decoder)" - PullRequest

Я могу воспроизвести сбой, передав потоковое видео H.265 на устройстве Android. Весь соответствующий код - блоки try-catch. Можно ли поймать исключение и предотвратить сбой приложения. Трассировка не указывает на код какого-либо приложения. Я подозреваю, что это не вызвано каким-либо конкретным утверждением.

Кажется, это вызвано "CHECK_EQ (reInitDecoder (), (status_t) OK);"в следующем коде :

   // 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;
    }

Есть ли способ узнать неподдерживаемые размеры декодера HEVC устройства Android?

Если вы запрашиваете способ получения поддерживаемых диапазонов различных параметров для кодека, вы можете использовать MediaCodecInfo.VideoCapabilities

В частности, вы можете получить поддерживаемые высоты и ширины, вызывая

Range<Integer>  getSupportedWidths() 
Range<Integer>  getSupportedHeights() 

Кроме того, вы можете получить поддерживаемые высоты для заданного значения ширины и наоборот, вызывая getSupportedHeightsFor(int width) и getSupportedWidthsFor(int height). Вы можете сделать то же самое для частоты кадров ...

Наконец, в вашем случае вы можете позвонить напрямую boolean isSizeSupported(int width, int height)

Пожалуйста, посмотрите на эту суть, чтобы получить отформатированные значения возможностей для данногоMedaCodec: https://gist.github.com/aelqsimi/f773d63fd5f234df7892276e3b05e5f8
