It is *always* printed when ffmpeg detects the use of -vbr or -qscale:a / -q:a with libfdk-aac. fdk-aac is an external encoder, so it, not ffmpeg, makes the decision on which rate control mode to ultimately use. Unfortunately, ffmpeg can't detect whether VBR mode was chosen, hence the warning is always printed. However, in your 2nd command, the output does look to be VBR. FTR, these are the target bitrates and accepted profiles for VBR as per its value: 1: 32 kbps mono AAC-LC + SBR + PS 2: 64 kbps stereo AAC-LC + SBR 3: 80 - 96 kbps stereo AAC-LC 4: 128 kbps stereo AAC-LC 5: 192 kbps stereo AAC-LC VBR looks to be unsupported with HE-AAC.

That's correct, mpdecimate currently only supports (taken from the source code): AV_PIX_FMT_YUV444P AV_PIX_FMT_YUV422P, AV_PIX_FMT_YUV420P, AV_PIX_FMT_YUV411P, AV_PIX_FMT_YUV410P, AV_PIX_FMT_YUV440P, AV_PIX_FMT_YUVJ444P, AV_PIX_FMT_YUVJ422P, AV_PIX_FMT_YUVJ420P AV_PIX_FMT_YUVJ440P, AV_PIX_FMT_YUVA420P, AV_PIX_FMT_GBRP, AV_PIX_FMT_YUVA444P, AV_PIX_FMT_YUVA422P Cheers, Moritz ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] A question on multiple audio variants support on HLS' var_stream_map parameters.
Hello there, With the var_stream_map option, can more than one audio stream variant exist in a group? From the documentation, all examples point to the creation of multiple audio groups, one per audio stream variant. Lifted straight from the wiki: https://ffmpeg.org/ffmpeg-formats.html#hls-2 This example creates the variant streams in subdirectories. Here, the first media playlist is created at http://example.com/live/vs_0/out.m3u8 and the second one at http://example.com/live/vs_1/out.m3u8. ffmpeg -re -i in.ts -b:a:0 32k -b:a:1 64k -b:v:0 1000k -b:v:1 3000k \ -map 0:a -map 0:a -map 0:v -map 0:v -f hls \ -var_stream_map "a:0,agroup:aud_low a:1,agroup:aud_high v:0,agroup:aud_low v:1,agroup:aud_high" \ -master_pl_name master.m3u8 \ http://example.com/live/out_%v.m3u8 Rather than separate the different audio variants into separate groups as shown above, can they be merged in one audio group, eg: ffmpeg -re -i in.ts -b:a:0 32k -b:a:1 64k -b:v:0 1000k -b:v:1 3000k \ -map 0:a -map 0:a -map 0:v -map 0:v -f hls \ -var_stream_map "a:,agroup:audio v:0,agroup:audio v:1,agroup:audio" \ -master_pl_name master.m3u8 \ http://example.com/live/out_%v.m3u8 Is such a configuration supported? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] Unable to enable libaom-av1 encoder
I want to try av1 codec so I tried to enable libaom encoder. However, I am not able to do so. I tried various commands from google, but whenever I tried to encode, it says: Codec 'libaom-av1' is not recognized by FFmpeg. Please let me know, how can I enable this encoder.
