  opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling. Using named define properly documents the code paths. It also avoids passing additional numbered arguments through multiple levels of macro templates. The suffix handling is done by concatenation, like in other asm functions and avoid having two separate "cglobal" defines. Signed-off-by: Ivan Kalvachev <ikalvachevⓐgmail.com> [DH] (...)

  FFMPEG distorting when resampling audio - jsamaudio Newest 'ffmpeg' Questions - Stack Overflow
  I'm making an mp3 from a flac file with ffmpeg. This is usually hum-dum for me. Tonight, for some reason, the converted audio is distorting when I use the same commands I've always used. After troubleshooting, it appears the problem is the "-out_sample_rate" flag. My command: ffmpeg -i input.flac -write_id3v1 1 -id3v2_version 3 -dither_method modified_e_weighted -out_sample_rate 44.1k -b:a 320k output.mp3 The audio in the mp3 is then incredibly distorted by a jacked gain resulting in digital clipping. I've tried updating ffmpeg, and then problem remains. I've tried converting various (...)

  Is it possible to create new mp4 file from a single streaming byte range chunk? - bevinlorenzo Newest 'ffmpeg' Questions - Stack Overflow
  If I have a remote mp4 file on a server that supports Byte Ranges, is it possible to retrieve a single byte range and create a new/self-contained mp4 from that range data? If I try and write a returned byte range data directly to an mp4 file using fs.createWriteStream(remoteFilename) it doesn't get the video meta data (duration, dimensions, etc) that it needs to be playable. When I get a byte range that starts with 0 and ends with XX the output mp4 is playable, but will have the duration meta-data of the entire video length and will freeze the screen when the byte range is done for the (...)
