Hi :) For testing purposes, I tried to encode a ProRes file using ffmpeg (current git HEAD). I have 2 questions about the FFmpeg docs about ProRes [1]:
1) Docs mention 2 encoder names, but only "prores" works: ======================================== When I looked at the documentation [1], there are 2 encoders mentioned: * prores-aw * prores-ks It says to use "-vcodec" to choose which one (btw: I also tried "-c:v"): I get: "Unknown encoder" for both. (Commandline and console output at the end) Using "-c:v prores" works, however. I've also checked "./configure --help | grep -i prores" but didn't find any compile switch to enable/disable them. 2) Docs say "profile/quantmat" is "integer", but only list strings: ======================================== [quote] profile integer Select the ProRes profile to encode ‘proxy’ ‘lt’ ‘standard’ ‘hq’ ‘4444’ ‘4444xq’ quant_mat integer Select quantization matrix. ‘auto’ ‘default’ ‘proxy’ ‘lt’ ‘standard’ ‘hq’ [/quote] Am I using it incorrectly, or is the documentation confusing? Thank you very much in advance, Peter == References: [1] https://ffmpeg.org/ffmpeg-all.html#ProRes Commandline and complete, uncut console output: (OS: Xubuntu 16.04.3 64bit)
