Can you make such a version, where something like FFMPEG-based NVENC HEVC and H264 and QSVENC H264 or HEVC will appear in the list of compressors in capture mode? Because MediaBrowser currently runs ffmpeg with -vcodec libx264 a change will need to be made to the MediaBrowser code to switch this to -vcodec h264_qsv Another issue is that MediaBrowser also favours WEBM for web browser streaming which does not use the h264 codec, as a result it will never be possible to use QuickSync to improve performance. This article documents some of the ffmpeg command line switches require to perform hardware video encoding on both NVIDIA and AMD GPUs. mp4 This program will do hardware mpeg2 or h264 encoding. If you remove -b:v 0, ffmpeg will always use a constant qc value, but with -b:v 0 set ffmpeg/nvenc can use a lower value (qmin) for scenes that are more complex (more quality). The video resolution is 1280x720, 30 fps, and encoded at 234 kbps using H. 264 or H.

It's CPU is rather underpowered, but if you add in a passively cooled Nvidia Kepler card (e. ffmpeg. 30 in Ubuntu 18. hevc H. 1, ffmpeg nvenc encoding Latest LQ Deal: Latest LQ Deals I also tried to find if FFMPEG supports codec for decoding AVC encoded files. png (68. Amongst lots of other changes, it includes all changes from ffmpeg-mt, libav master of 2015-08-28, libav 11 as of 2015-08-28. I want to encode a full HD video with originally 6000kbits but ffmpeg encode the video with CRF to max 1800kbits. 264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_cuvid ) (encoders: h264_nvenc nvenc nvenc_h264 ) D. 73 18. 295 ffmpeg -i source. 264-enable-encoder=nvenc –enable-nvenc –enable-nonfree. nvenc编码. mp4 -c:v h264_nvenc -profile:v high -level 5. 264 encoder Question 2: Old devices can play NVENC H264 file same as x264? Old devices : (All devices that can play x264) Android 6+, TV Setup box, TV, Google chrome 48+ video ffmpeg h. 04 using the latest branch of FFmpeg to do an h264_amf encode with varying success. The encoded videos with the nvenc_h264 engine are bigger, but your are able to encode like 100 times faster. User can use the full potential of ffmpeg in a convenient GUI, using any set of parameters, which can be tried for a small part of any file prior to start ffmpeg. 265 encoding support via around 130 lines of new code. For NVENC-based encoders, start with learning the options each encoder takes (Note that I'm on Linux, which is why I'm using xclip to copy the codec options to the clipboard prior to pasting them here): (a). so. mkv. LS h264 H. With FFmpeg, you can always refer to an encoder's settings for customization by: ffmpeg -h encoder {encoder-name} So, for NVENC-based encoders, you can run: ffmpeg -h encoder=hevc_nvenc ffmpeg -h encoder=h264_nvenc You can also see all the NVENC-based encoders and NPP-based scalers (if built as such) by running: h264_nvenc uses the NVidia hardware assisted H. 1 [h264_nvenc @ 0x29760a0] Nvenc initialized successfully [h264_nvenc @ 0x29760a0] 2 CUDA capable devices found Example [transcode from h264/avc to h265/hevc with lowering the bitrate to 5Mbps]: ffmpeg -hwaccel qsv -c:v h264_qsv-i test. h264 -loglevel verbose Here is an example of the log message: To overcome the incorrect order issues, consider using " video::interlace=progressive " in your encoding configurations. Command line below shows how to run FFmpeg Remap filter on GPU for h264-encoded video in mp4 container: ffmpeg -y -vsync 0 -hwaccel cuvid -c:v h264_cuvid -i source. 264 is quite common. Few things to note: REM basically comments out the line so if you want to change encoder to hevc_nvenc (H. mp4 命令说明:-c:v 这个是-vocdec的缩写 意思是编解码方式-c:v h264_cuvid 这个的意思就是使用英伟达GPU解码-i 这个是输入的意思 FFmpeg has obviously supported VDPAU for a number of years now while landing this week into Git is initial NVDEC decoding of H. 04. mp4': Metadata: major_brand : isom ffmpeg -hwaccel cuvid -c:v h264_cuvid -i <input> -c:v h264_nvenc -b:v 2048k -vf scale_npp=1280:-1 -y <output> -hwaccel cuvid: Specify using cuvid hardware acceleration-c:v h264_cuvid: use h264_cuvid for video decoding-c:v h264_nvenc: use h264_nvenc for video encoding as the nvenc are missing from the list of supported encoders in the linux binary I deduced they've been compiled without nvidia hardware acceleration I don't know why as far as I can tell nvenc is bundeled in the ffmpeg source tree and the intel h264_vaapi does show up as a supported encoder Check that FFmpeg works. They differ in how frames are decoded and forwarded in memory. avc On2 Audio for Video Codec (decoders: on2avc ) A small yet quite capable Bash shell script written for the GNU/Linux and BSD operating systems for encoding video files to the H. mp4" Pero la calidad no es tan buena como se esperaba. h264 nvenc ffmpeg
