  avcodec/v4l2_m2m_enc : Enable frame level rate control by default
  Without this setting, bitrate and qmin/qmax options have no
  
  effect on the s5p-mfc hardware encoder.

• avformat/matroskaenc : Write level 1 elements in one go

  30 décembre 2019, par Andreas Rheinhardt

  avformat/matroskaenc : Write level 1 elements in one go
  Up until now, writing level 1 elements proceeded as follows : First, the
  
  element id was written to the ordinary output AVIOContext and a dynamic
  
  buffer was opened for the content of the level 1 element in
  
  start_ebml_master_crc32(). Then this buffer was actually used and after it
  
  was closed (in end_ebml_master_crc32()), the size field corresponding to
  
  the buffer's size was written, after which the actual data was written.
  This commit changes this : Nothing is written to the main AVIOContext any
  
  more in start_ebml_master_crc32(). end_ebml_master_crc32() now writes
  
  both the id, the length field as well as the data. This implies that
  
  one can start a level 1 element in memory without outputting anything.
  
  This is done to enable to test whether enough space has been reserved
  
  for the Cues (if space has been reserved for them) before writing them.
  
  A large duration between outputting the header and outputting the rest
  
  could also break certain streaming usecases like the one from #8578
  
  (which this commit fixes).

• FFMPEG profile-level-id size is invalid

  18 février 2020, par Mulham Aryan

  I’m trying to record a RTSP streaming from JVC KY-PZ 100.
  So for that i’m using ffmpeg with some parameters like segmentation, hls, ts, m3u8 etc ...
  i’m always getting an error The profile-level-id field size is invalid (41) and Error parsing AU headers

  This is the output of FFPROBE to debug the RTSP
