• Laravel ffmpeg failed to execute command

  4 septembre 2022, par John smith

  I'm using protonemedia/laravel-ffmpeg package everything works fine on localhost but on the live server, there is an error message shown.

  I'm storing the key at custom disk "streamable_keys", and converted videos should be stored in "streamable_videos".

  


  the streamable keys are generated and saved to a directory without any issues, but streamable videos are not saved to the directory.

  


  after some tracks I found that the problem happens in this line of code :

  


          ->save($this->video->id . '.m3u8');


  


  all the lines before that line work perfectly.

  


  any ideas on how to fix that ?

• Syncing 3 RTSP video streams in ffmpeg

  26 septembre 2017, par Damon Maria

  I’m using an AXIS Q3708 camera. It internally has 3 sensors to create a 180º view. Each sensor puts out it’s own RTSP stream. To put together the full 180º view I need to pull an image from each stream and place the images side-by-side. Obviously it’s important that the 3 streams be synchronized so the 3 images were taken at the same ’wall clock’ time. For this reason I want to use ffmpeg because it should be a champ at this.

  I intended to use the hstack filter to combine the 3 images. However, it’s causing me a lot of grief and errors.

  What I’ve tried :

  1. Hstack the rtsp streams :

  ffmpeg -i "rtsp://root:root@192.168.13.104/axis-media/media.amp?camera=1" -i "rtsp://root:root@192.168.13.104/axis-media/media.amp?camera=2" -i "rtsp://root:root@192.168.13.104/axis-media/media.amp?camera=3" -filter_complex "[0:v][1:v][2:v]hstack=inputs=3[v]" -map "[v]" out.mp4

  I get lots of RTSP dropped packets decoding errors which is strange given this is an i7-7700K 4.2GHz with an NVIDIA GTX 1080 Ti and 32GB of RAM and the camera is on a local gigabit network :

  [rtsp @ 0xd4eca42a00] max delay reached. need to consume packetA dup=0 drop=136 speed=1.16x    
  
  [rtsp @ 0xd4eca42a00] RTP: missed 5 packets
  
  [rtsp @ 0xd4eca42a00] max delay reached. need to consume packetA dup=0 drop=137 speed=1.15x    
  
  [rtsp @ 0xd4eca42a00] RTP: missed 4 packets
  
  [h264 @ 0xd4ecbb3520] error while decoding MB 14 15, bytestream -21
  
  [h264 @ 0xd4ecbb3520] concealing 1185 DC, 1185 AC, 1185 MV errors in P frame

  2. Using ffmpeg -i %s -c:v copy -map 0:0 out.mp4 to save each stream to a file and then run the above hstack command with the 3 files rather than 3 RSTP streams. First off, there are no dropped packets saving the files, and the hstack runs at speed=25x so I don’t know why the operation in 1 had so many errors. But in the resulting video, some parts ’pause’ between frames as tho the same image was used across 2 frames for some of the hstack inputs, but not the others. Also, the ’scene’ at a set distance into the video lags behind the input videos – which would happen if the frames are being duplicated.

  3. If I use the RTSP streams as the input, and for the output specify -f null - (the null demuxer) then the demuxer reports a lot of these errors :

  [null @ 0x76afb1a060] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 1 >= 1
  
      Last message repeated 1 times
  
  [null @ 0x76afb1a060] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 2 >= 2
  
  [null @ 0x76afb1a060] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 3 >= 3
  
  [null @ 0x76afb1a060] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 4 >= 4
  
      Last message repeated 1 times
  
  [null @ 0x76afb1a060] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 5 >= 5
  
      Last message repeated 1 times

  Which sounds again like frames are being duplicated.

  4. If I add -vsync cfr then the null muxer no longer reports non monotonically increasing dts, and dropped packet / decoding errors are reduced (but still there). Does this show that timing info from the RTSP streams is ’tripping up’ ffmpeg ? I presume it’s not a solution tho because it is essentially wiping out and replacing the timing information ffmpeg would need to use to sync ?

  5. Saving a single RTSP stream (re-encoding, not using the copy codec or null demuxer) logs a lot of warnings like :

  Past duration 0.999992 too large
  
      Last message repeated 7 times
  
  Past duration 0.999947 too large
  
  Past duration 0.999992 too large

  6. I first tried performing this in code (using PyAV). But struck problems when pushing a frame from each container into the 3 hstack inputs would cause hstack to output multiple frames (when it should be only one). Again, this points to hstack duplicating frames.

  7. I have used Wireshark to sniff the RTCP/RTP traffic and the RTCP Sender Report’s have correct NTP timestamps in them matched to the timestamps in the RTP streams.

  8. Using ffprobe to show the frames of a RTSP stream (example below) I would have expected to see real (NTP based timestamps) given they exist in the RTCP packets. I’m not sure what is correct behaviour for ffprobe. But it does show that most frame timestamps are not exactly 0.25s (the camera is running 4 FPS) which might explain -vsync cfr ’fixing’ some issues and the Past duration 0.999992 style errors :

  pkt_pts=1012502
  
  pkt_pts_time=0:00:11.250022
  
  pkt_dts=1012502
  
  pkt_dts_time=0:00:11.250022
  
  best_effort_timestamp=1012502
  
  best_effort_timestamp_time=0:00:11.250022
  
  pkt_duration=N/A
  
  pkt_duration_time=N/A
  
  pkt_pos=N/A

  I posted this as a possible hstack bug on the ffmpeg bug tracker but that discussion fizzled out.

  So, question : how do I sync 3 RTSP video streams through hstack in ffmpeg ?

• ffmpeg nvdec not available when adding subtitles to mp4

  17 février 2019, par whatdoineed2do

  I have a mp4 video that I want to BURN-IN subtitles (from a .ass file and via -vf ass=/tmp/conf-notes.ass) with ffmpeg on a machine with a GTX1060 card however ffmpeg reports that it fails to create the NVDEC decoder.

  [h264 @ 0xcb9380] Error creating a NVDEC decoder: 1
  
  [h264 @ 0xcb9380] Failed setup for format cuda: hwaccel initialisation returned error.

  The output file is generated ok but during the creation the CPU is used heavily (I assume for decode) - if I drop the -vf ass=/tmp/conf-notes.ass and perform an mp4->mp4 reencode there are no problems.

  I want to know what I am missing from my command to allow the GPU to perform the decode when an .ass file is added to the chain.

  $ ffmpeg -hwaccel cuvid -i 2019-01-conferance.mp4 -vf ass=/tmp/conf-notes.ass -c:a copy -preset llhq -rc vbr_hq -vb 2M -minrate 500k -maxrate 12M -c:v h264_nvenc export.mp4
