Save continuous RTSP stream to 5-10 minute long mp4 files
20 janvier 2017, par Ruslan SharipovHow can I keep the flow (protocol rtsp, codec h264) in file (container mp4) ? That is, on inputting an endless stream (with CCTV camera), and the output files in mp4 format size of 5-10 minutes of recording time.
OS : debian, ubuntu
Software : vlc, ffmpeg (avconv)Currently this scheme is used :
cvlc rtsp://admin:admin@10.1.1.1:554/ch1-s1 --sout=file/ts:stream.ts
ffmpeg -i stream.ts -vcodec copy -f mp4 stream.mp4But it can not record video continuously (between restarts vlc loses about 10 seconds of live video).

FFMPEG / MJPEG Encoding / How to add DQT table in packet data ?
20 mai 2020, par GoodSimonI write my own transcoder in C++ to convert any image to jpeg based on the examples in ffmpeg sources. I use the MJPEG codec to create a jpeg image. By sending AVFrame to the MJPEG encoder I get AVPacket. Then I just take the data from the packet->data structure with the size avpacket->size and save it to a file with the jpg extension.
The problem is that the finished JPEG image has only one DQT (Define Quantization Table). As far as I understand, there should be two tables in the file.



What do I need to do to have 2 quantization tables in avpacket->data ?
