• omxplayer freezes with videos generated with FFMPEG

  31 décembre 2020, par Chocksmith

  Omxplayer won't play any videos generated with FFmpeg on a Raspberry Pi

  


  I found this thread showing that it is necessary to include '-profile baseline -level 3.0' parameters : https://github.com/popcornmix/omxplayer/issues/577

  


  The full command is :

  


  ffmpeg -framerate 1/10 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p -profile baseline -level 3.0 images.mp4


  


  I did that and now I am experiencing intermittent behavior.

  


  Sometimes it works and sometimes it does not work. I cannot explain why/when it plays or not.

  


  I also found a thread showing that it is necessary to upgrade the firmware and player. I did that and still having the same issue.

  


  Here is an example. First time it plays ok. Second time it freezes.

  


  First time : creating mp4

• FFmpeg skipping time after concat

  19 septembre 2017, par Manul Hüttinger

  I am trying to concatenate videos and in my resulting Videos I have the issue that at the concat edges my video is skipping/glitching.

  ---

  General Workflow

  in general my workflow looks like this

  1. Stream via ffmpeg
  2. capture stream and segment all 2 mins in to TS files
  3. concat TS file to MP4 video
  4. cut MP4 video at the desired Timestamps

  ---

  Detailed Look at Step 4

  as I am handling 2-hours+ videos I don’t want to re-encode the whole video. So I am looking for the closest I Frames to my In and Outpoint and cut 1 Frame before/after. As my result I get 3 Videos (front/middle/back). Now it is only needed to re-encode front and back and concat all three Videos.
  So far the theory

  ---

  General Observations

  As I look at my resulting video, I obeservated the following.
  frontpart duration is e.g. 3.2 secs. I skip framewise through the Video and get nice and clean timestamps ( 00:00:02.620, 00:00:02:660 )
  As soon as I get to my cutting edge the timestamps are skipping some frames and changing (00:00:03.200, 00:00:03.408 ,00:00:03.409). When I look only at the single frame images, their are no missing/dropped frames

  when I concat my TS files, the results contains a messed up frame rate e.g from constant 25 F/s to 25.0096 F/s

• Using ffserver to stream older IP cam MJPEG to RTSP

  26 mai 2016, par tmar89

  I have an older Sony IP camera that has an MJPEG stream. I need to connect this to an NVR that only takes ONVIP or RTSP and I’m trying to use ffserver and ffmpeg to convert the MJPEG stream to RTSP but it’s not working. Any have some idea of what I may be doing wrong ? Saw an error in the attempted playback about an unsupported Protocol.
  Here is my ffserver config :

  Port 8090
  
  RTSPPort 5544
  
  BindAddress 0.0.0.0
  
  RTSPBindAddress 0.0.0.0
  
  MaxClients 100
  
  MaxBandwidth 10000
  
  
  
  <feed>
  
  File /tmp/feed27.ffm
  
  FileMaxSize 5M
  
  ACL allow 127.0.0.1
  
  </feed>
  
  
  
  <stream>
  
  Format rtp
  
  Feed feed27.ffm
  
  NoAudio
  
  VideoCodec mjpeg
  
  VideoFrameRate 30
  
  VideoSize 736x480
  
  </stream>

  And here is the ffmpeg command I am using :

  [tm@tele ffserver-rtsp]# ffmpeg -f mjpeg -r 30 -s 736x480 -i http://[CAMIP]/image http://localhost:8090/feed27.ffm
