Run application in background with delete operation
14 décembre 2016, par RoiEXI have the following code in my php script :
exec ( "start ./ffmpeg.exe -i \"" . $inFile . '" "' . $outFile . '"' );
unlink ( $inFile );As you may have guessed, this code will not work, because ffmpeg is started, but the file is going to be deleted before ffmpeg finishes. (Or the deletion process will fail because the file is being used.)
I want to execute ffmpeg asynchronously using start, but delete the input file on success. I tried adding
&& del $inFile, but this has the same effect as my code.For those of you who don’t know what start does ; it starts the given command in a new process, causing the exec function to return immediately.
Any help is appreciated :)

Is there a way to parse Hevc rtsp packets and find height and width in c++ application
2 août 2021, par dinesh47I have written a C++ application with processing of RTP video and Audio packet(Bitstream packets) but can't able to find a way to get height and width from VPs,SPs or PPs from every keyframe.
Note:I am using only pure c++ codes until encoding and writing the file part with ffmpeg lib


Need to know How to Extract it from that extra data for Memcopy it to add with start code.


Need to find Height and width with it(Parsing).


i have Written in case like the folowing :


byte *packet=&*(frameData);
int size =ptr->m_size;
boost::shared_ptr<byte> dst ;
int naltype = (packet[0] >> 1) & 0x3f;

switch(naltype)
{
case HEVC_NAL_VPS:
 m_vpsSize=(size)+4;
 m_vpsHeader[3]=1;
 memcpy(&m_vpsHeader[4],&packet[0],size); //need size and packet start and End dimension
 break;
case HEVC_NAL_SPS:
 m_spsSize=(size)+4;
 m_spsHeader[3]=1;
 memcpy(&m_spsHeader[4],&packet[0],size);//need size and packet start and End dimension
 break;
case HEVC_NAL_PPS:
 m_ppsSize=(size)+4;
 m_ppsHeader[3]=1;
 memcpy(&m_ppsHeader[4],&packet[0],size);//need size and packet start and End dimension
 break;
case 49:
 byte new_nal_header[2]={0};
 int startFU=packet[2]&0x80;
 int endFU = packet[2]&0x40;
 int fuType=packet[2] & 0x3f;
 new_nal_header[0] = (packet[0] & 0x81) | (fuType<<1);
 new_nal_header[1]=packet[1];

}
</byte>

Adding cover art to video wtih chapters and chapters getting deleted
31 mai 2021, par throwaway513I am trying to add a cover art to a video with chapters.


I added 2 chapters to a video using :


ffmpeg -i 1.mp4 -i Chapters.txt -map_metadata 1 -c copy 2.mp4

but when I try to add cover art it deletes the first chapter and only keeps the second ?


ffmpeg -i 2.mp4 -i image.jpg -map 1 -map 0 -c copy -disposition:0 attached_pic 3.mp4

I also tried mp3tag but the picture doesn't show on the file after adding chapters through ffmpeg. Chapters work fine on 2.mp4 but on 3.mp4 it deletes the first chapter. It also deletes the chapter when I do
ffmpeg -i 2.mp4 -c copy any.mp4
