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>

FFmpeg more than 1000 frames duplicated and input height doesn't match
2 septembre 2021, par KarineI'm currently using this code to record two windows side by side :


ffmpeg -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -c:v h264_nvenc -qp 0 -filter_complex hstack=inputs=2 2.mp4


However it throw this error after execution :


More than 1000 frames duplicated


Error Log : https://pastebin.com/gREVrKVK


The first window mostly time is the same frame, maybe 1 frame change in each 3 sec.


Another error in console is when the first window have a different height than second window, error :


[Parsed_hstack_0 @ 000002491166fd00] Input 1 height 500 does not match input 0 height 488.
[Parsed_hstack_0 @ 000002491166fd00] Failed to configure output pad on Parsed_hstack_0


Error log : https://pastebin.com/vqdBPfpv


Looks like is not possible to record when they have different dimensions, so, if possible I would like to ask how to scale the first window to the same height (doesn't need to keep aspect ratio) of the second window, considering low CPU use above the video quality.
