• TTML subtitle missing in HLS

  I tried to inject a ttml subtitle into a mp4 file using the following command.

  


  docker run --rm -v `pwd`:/work sambaiz/mp4box -add  my.ttml input.mp4

  On playing the input.mp4 with exo player i was able to see the injected ttml subtitle.

  


  Now im trying to conver this mp4 file in to hls using the following command

  


  ffmpeg -i input.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8

  


  ffmpeg -i input.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8

• Is there any option to create a single frame thumbnail for a video in java ?

  13 juin 2020, par Prashanth Shyamprasad

  Is there any option to create a single frame thumbnail for a video in java with java libraries.

  



  I am using Jave2 in my application. Does Jave2 provides any such options ? I didn't find a single documentation related to this.

  



  I heard Xuggler provides some options. But I don't want to move to Xuggler if Jave2 provides the facility as I'm already using Jave2 for many purposes extensively. Adding a full library like Xuggler is an overhead. Replacing Jave2 with Xuggler also is a tedious task

  



  If any light weight thumbnail feature specific utility library is available, then that should also be fine.

  


• Q. FFMPEG - linux (Rasberry pi 4- Raspbian)- FFMPEG av_read_frame error

  Good morning. I have a question and post it.

  



  When Raspbian is installed, the installed FFMPEG library is used.

  



  I want to output a video display - file encoded in h264 using gtk3.0.

  



  When I open the video file & find the codec and try to read the frame,
I get an error and I'm asking.Error symptoms

  



  

  1. AVPacket struct memory padding ? error

  


  



  2.AVPacket-data error:Cannot access memory at address 0xxxxxxxxxxxx>

  



  

  3. AVPacket-stream_index value error- The stream_index and flags values ​​seem to have been reversed.

  


  



  my source code and error photos are attached.
Thank you.

  



  case 1 stream_index error (flags value ->stream_index)
