• ffmpeg doesn't record RTSP stream

  7 août 2023, par zcoder

  I'm trying to record RTSP stream from Dahua IP camera which is located on 10.10.10.10 (for example purpose), on Windows it works well and on previous ubuntu version I had (18) it was also working well.
However on Ubuntu Server 22.04 it runs but ends without any error.

  


  My command :
ffmpeg -loglevel debug -i rtsp://admin:admin@10.10.10.10:554/cam/realmonitor?channel=1"&"subtype=1 -movflags +frag_keyframe+separate_moof+omit_tfhd_offset+empty_moov -acodec copy -vcodec copy out.mp4

  


  And debug output of the ffmpeg is :

• linker error in Android NDK r25c when cross-compiling FFmpeg

  5 août 2023, par Sai Chaithanya

  I am cross compiling FFmpeg for Android(aarch64) using Android NDK r25c on Linux x86_64 platform. The errors generated by the linker are because of enabling the LTO option.
  
On disabling the LTO options(--enable-lto optional config and -flto=thin cc-flag), there are no failures.

  


  FFmpeg config :

  I also compiled LAME encoder (version 3.100) with LTO options, and it worked just fine.
  
How to resolve the error ?

  


  **The libLTO.so file is present under lib64/ hence added that to the —extra-ldflags optional config.

• ffmpeg command for faster encoding at a decent bitrate with smaller file size

  28 juillet 2023, par Blair Holmes

  I'm currently using an implementation of ffmpeg on my android app. I'm allowing users to take short videos within my app and then when they upload them to the server, I'm crunching them down with ffmpeg to decrease file size so they're not passing huge amounts of data over the wire.

  



  the problem is, it's taking forever to encode the videos on the android device. These videos usually aren't longer than 45 seconds and can take 20 minutes to encode. I've done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I'm just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

  



  Here are the two commands I've been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it's encoding for so long :

  



  ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4


  



  I've tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don't want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

  



  ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4


  



  I'd like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it's difficult to wrap my head around what I should be doing.

  



  EDIT : adding ffmpeg output.

  



  ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4
