• avutil/mips : refactor msa load and store macros.

  17 juillet 2019, par Shiyou Yin

  avutil/mips : refactor msa load and store macros.
  Replace STnxm_UB and LDnxm_SH with new macros ST_H/W/D1/2/4/8.
  
  The old macros are difficult to use because they don't follow the same parameter passing rules.
  
  Changing details as following :
  
  1. remove LD4x4_SH.
  
  2. replace ST2x4_UB with ST_H4.
  
  3. replace ST4x2_UB with ST_W2.
  
  4. replace ST4x4_UB with ST_W4.
  
  5. replace ST4x8_UB with ST_W8.
  
  6. replace ST6x4_UB with ST_W2 and ST_H2.
  
  7. replace ST8x1_UB with ST_D1.
  
  8. replace ST8x2_UB with ST_D2.
  
  9. replace ST8x4_UB with ST_D4.
  
  10. replace ST8x8_UB with ST_D8.
  
  11. replace ST12x4_UB with ST_D4 and ST_W4.
  Examples of new macro : ST_H4(in, idx0, idx1, idx2, idx3, pdst, stride)
  
  ST_H4 store four half-word elements in vector 'in' to pdst with stride.
  
  About the macro name :
  
  1) 'ST' means store operation.
  
  2) 'H/W/D' means type of vector element is 'half-word/word/double-word'.
  
  3) Number '1/2/4/8' means how many elements will be stored.
  
  About the macro parameter :
  
  1) 'in0, in1...' 128-bits vector.
  
  2) 'idx0, idx1...' elements index.
  
  3) 'pdst' destination pointer to store to
  
  4) 'stride' stride of each store operation.

• fftools/ffmpeg_mux : stop using filter_in_rescale_delta_last for streamcopy

  13 avril 2023, par Anton Khirnov

  fftools/ffmpeg_mux : stop using filter_in_rescale_delta_last for streamcopy
  That field was added to store timestamp conversion state for audio
  
  decoding code. Later it started being used by streamcopy as well, but
  
  that use is wrong because, for a given input stream, both decoding and
  
  an arbitrary number of streamcopies may be performed simultaneously.
  
  They would then all overwrite the same state variable.
  Store this state in MuxStream instead.
  This is the last use of InputStream in of_streamcopy(), so the ist
  
  parameter can now be removed.
