• I am phasing a issue of " ffmpeg attribute 'error'" in my project which is a voice command assistant using GPT 3.5 Turbo and BING API [closed]

  2 mai 2023, par Rudraksh Singh Bhadauria

  I ma working on a pyhton project as want to make a program which can work as fluent as GPT and can also adapt latest news through BING API but after trying a lot I am stuck with a issue where "Error transcribing audio : module 'ffmpeg' has no attribute 'Error'" I have tried installing these ffmpeg files again and again in the way already mentioned in stack overflow but for me its not working.

  


  I have tried using :
installing ffmpeg-pyhton in my terminal and also ffmpeg module and also I have reinstalled the whole files and also have put them in my environment variables.
If anyone could help me to sort this problem out then it will be great help.

  


• ffmpeg segment naming of rtsp surveillance stream HikVisions

  20 juillet 2022, par kenneth558

  I need to ensure unique segment names : Apparent POE cable defects, etc. around campus cause HikVision camera streams to require their ffmpeg daemons re-started once or twice or more times/day. (I am miles away from this campus for the most part, so I prefer a command line fix until the hardware fixes get applied.) When ffmpeg has to be restarted for a camera (by background bash script), I need the names of the new .mp4 segments positively not to be the same as any previous names.

  


  Background bash process currently does fine to specify an acceptable ddHHMM style new starting name for the first segment after ffmpeg restart BUT after the first or sometime second or third segment is made, ffmpeg insists on future naming to default to an unacceptable YYYmmdd style and thus start to overwrite previous segments. I use "$(date +%d%H%M)" to obtain my acceptable date style.

  


  I've tried a lot of different combinations of date codes and date embedding and both ssegment and segment muxers ; also I know very little of the very complex realm that ffmpeg is normally used in outside of simple rtsp stream copy to .mp4 files.

  


  ffmpeg command that is launched from inside bash script :
bash -c 'nohup ffmpeg -nostdin -stimeout 10000000 -rtsp_transport udp -i "rtsp://192.168.0.11:6554/Streaming/channels/101" -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -c:v libx264 -f ssegment -strftime 0 -segment_time 180 -segment_format_options movflags=+faststart -reset_timestamps 0 -increment_tc 1 -avoid_negative_ts 1 -c copy -flags +global_header /var/www/camera_streams/camera_east_driveway/"$(date +%d%H%M)"_%3d.mp4 > /dev/null 2>/dev/null & '

  


  Can the segment naming pattern be carried forward indefinitely like I want ? Honestly, I wonder if ffmpeg does not allow for my specific use case naming need ?

  


  (Yes, I know changing from udp to tcp can help, but I don't consider it to be the specific solid naming fix I'm hoping for right now. And I mention HikVision in case there is known frame encoding differences for them than other cameras)

  


• Can FFMPEG pause a live audio recording when db levels fall below threshold ?

  30 avril 2020, par DeepTrik

  I am in the process of converting 100's of audio cassettes to FLAC files. I have used Audacity and RecordPad by NCH Software to set decibel (dB) thresholds. so that when my devices stop and require a tape flip, the recording also pauses.

  



  I would like to move my tape playing devices (USB-based) to ubuntu 18.04 and run them on FFMPEG, but was wondering if FFMPEG had the ability to pause the recording when the audio signal falls below a configurable threshold.

  



  This helps me reduce the storage waste. Soon I have to convert some older audio reels as well in which the problem will get worse.

  



  The probe with Audacity is limited # of instances. If Audacity allowed me to instantiate multiple instances (1 for each playback device), I wouldn't be asking this question.

  



  I'm a bit of a noob to shell scripting...here is the end of my current shell script :

  



  nohup ffmpeg -nostdin -f alsa -i hw:"$DEVICE" -t $DURATION  -filter:a volumedetect -ar 48000 -ac 2 -b:a 320k "$TITLE".flac 2> "$TITLE".log &

  



  Thanks in advance !
