• Could not write header for output file #0 (incorrect codec parameters ?) : No such file or directory Error initializing output stream 0:5 —

  13 septembre 2022, par M E

  I am trying to create a DASH manifest and segments from an .mp4 file. I have created a bash files with the commands below, and calling bbb.mp4, but the output gives the error on the subject line. This is the script I am using :

  


  ffmpeg -re -i bbb.mp4 -map 0 -map 0 -c:a aac -c:v libx264 \
-b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline \
-profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 \
-b_strategy 0 -ar:a:1 22050 -use_timeline 1 -use_template 1 \
-window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \
-f dash /path/to/out.mpd


  


  After running the command for my bash file dash-demo I get :

• What is wrong with mjpeg stream, ffserver and ffplay ?

  So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver ?

• Seeking with FFMPEG at the end of an RTSP stream

  30 juillet 2019, par kealist

  I am using ffmpeg to play RTSP streams in an application. I have been running into a problem that once I reach the end of an RTSP stream, I am no longer able to see back to anywhere in the stream.

  The program I am writing is using LGPL shared libraries, but I can see the same behavior using ffplay using GPL version.

  ffplay.exe "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"

  While the video is playing, I can seek forward or backwards using the keyboard shortcuts for ffplay (left / right arrow key). Once the stream reaches the end, it is not possible and the stream is paused or playing, seeking no longer works. I see errors in the shared lib, but in ffplay, I do not see errors unless I use the s key (which may make sense that I cannot seek). In other streams, I have seen an issue where the stream is longer than the reported length, and once the extra video is buffered/downloaded, it is not possible to seek. Any guidance on what is going on here ?

  Using ffplay.exe (also verified with newer build) :

  With -v trace I can see that there is a Seek message, but no seeking actually occurs whether it is paused or playing.

  Is there a way to mitigate this without reloading the stream ?
