FFMpeg iOS

Question

kullanarak kamera akışı video karesini deşifre ederken bir hata var Uygulamam var, IP kameradan gelen video karelerinin kodunu çözüyorum ama 'da bulunan ve bad_access'i oluşturan yöntem, neyin yanlış olduğunu anlayamıyorum.

Bu uygulama eski kitaplıklar FFMpeg ile çalışıyordu, ancak elma politikasıyla, uygulamayı yayınlamak için arm64'ü destekledim, bu yüzden kol64'ü desteklemek için kitaplıklarımı güncelleştirdim ve bundan sonra bu sorun oluştu.

Answer 1

Sorunumu çözdüm Sorun, avcodec_alloc_frame() amortismanlı yöntemle ilgiliydi.

Ben

m_pCodecCtx = avcodec_alloc_context3(m_pCodec); 
    if(m_pCodecCtx == NULL) 
    { 
     NSLog(@"if(pCodecCtx == NULL)\n"); 
     return ; 
    } 
    [g_Lock lock]; 
    //¥Úø™codec°£»Áπ˚¥Úø™≥…𶵃ª∞£¨∑÷≈‰AVFrame£  
    if(avcodec_open2(m_pCodecCtx, m_pCodec, NULL) >= 0)  
    {  
     m_pFrame = avcodec_alloc_frame(); /* Allocate video frame */ 

    } 
    [g_Lock unlock]; 

Sonra sonunda güncellenecek benim başlık dosyalarının yapıcı

aşağıdaki kodu kullanıyordum, sonra ben çok yöntemin avcodec_alloc_frame() değer kaybetmesi hakkında uyarılar, ben av_frame_alloc() güncellemiş var ve sorunsuz çalıştı!
