Malloc Check Failed when opening video stream
23 août 2013, par donturnerI'm writing a BlackBerry 10 application which decodes an H264 video stream (from a Parrot AR Drone) using ffmpeg and libx264. These libraries have both been compiled for BlackBerry QNX.
Here's my code :
av_register_all();
avcodec_register_all();
avformat_network_init();
printf("AV setup complete\n");
const char* drone_addr = "http://192.168.1.1:5555";
AVFormatContext* pFormatCtx = NULL;
AVInputFormat* pInputFormat = av_find_input_format("H264");
printf("Opening video feed from drone\n");
//THIS LINE FAILS
int result = avformat_open_input(&pFormatCtx, drone_addr, pInputFormat, NULL);The last line fails with the error :
Malloc Check Failed: :../../dlist.c:1168
How can I fix this error or debug it further ?
Update : The error only occurs when I supply
pInputFormat
toavformat_open_input
. If I supply NULL I don't get an error. But for my app I must supply this parameter since it is not possible for ffmpeg to determine the video format from the feed alone. -
Ne plus utiliser qt-faststart
28 août 2013Il est possible d’éviter d’utiliser
qt-faststart
en utilisant le paramètre-moveflags
dans la commande de FFMpeg depuis ce commit : http://git.videolan.org/?p=ffmpeg.git ;a=commit ;h=a714150827c70f8baf2ec42dfecd9363c17e803d (soit depuis moins d’une année lors de la rédaction du ticket).Son utilisation est un peu expliqué ici :

FFmpeg CLI - transcode only if necessary
23 septembre 2018, par TyrrrzI want to mux an audio and video stream into a single video file. These two streams come in arbitrary formats. Sometimes the input and output encodings will match, in which case I would want to save a lot of processing time by using
-c copy
argument that tells FFmpeg to avoid transcoding.Is there a way to tell FFmpeg to automatically determine if transcoding is required, based on the formats of input files ? Alternatively, I can do the check myself, but I would prefer for FFmpeg to do in on its own, if possible.
