• av_interleaved_write_frame return 0 but no data written

  11 août 2015, par Jerikc XIONG

  I use the ffmpeg to stream the encoded aac data , i use the

  av_interleaved_write_frame()

  to write frame.

  The return value is 0,and it means success as the description.

  Write a packet to an output media file ensuring correct interleaving.

  The packet must contain one audio or video frame. If the packets are already correctly interleaved, the application should call av_write_frame() instead as it is slightly faster. It is also important to keep in mind that completely non-interleaved input will need huge amounts of memory to interleave with this, so it is preferable to interleave at the demuxer level.

  Parameters

  s media file handle

  pkt The packet containing the data to be written. pkt->buf must be set to a valid AVBufferRef describing the packet data. Libavformat takes ownership of this reference and will unref it when it sees fit. The caller must not access the data through this reference after this function returns. This can be NULL (at any time, not just at the end), to flush the interleaving queues. Packet’s stream_index field must be set to the index of the corresponding stream in s.streams. It is very strongly recommended that timing information (pts, dts duration) is set to correct values.

  Returns

  0 on success, a negative AVERROR on error.

  However, I found no data written.

  What did i miss ? How to solve it ?

• How do I avoid batch video transcoding error when encountering whitespaces in filename using ffmpeg [duplicate]

  This question already has an answer here :

  • Looping through find output in Bash where file name contains white spaces

  I am running a bash script to batch transcode videos on a LAMP server using find and ffmpeg

  dir="/srv/videos"
  
  for OUTPUT in "$(find $dir -iname *.AVI -o -iname *.MOV)"
  
  do
  
      ffmpeg -i "$OUTPUT" "${OUTPUT%%.*}.mp4"  -hide_banner
  
  done

  ffmpeg returns an error if file has whitespaces

   /srv/videos/file with white spaces.MOV: No such file or directory

  For files without white spaces it works fine.
  If I print the filenames inside quotes it looks as though it should be working

  for OUTPUT in "$(find $dir -iname *.MOV)"; do echo "$OUTPUT";done

  returns

  /srv/videos/file with white spaces.MOV

  What do I need to alter to avoid the error please ?

  EDIT
  added "" to $OUTPUT%%.*.mp4, I get the same error and corrected extension capitalisation (mov to MOV)
