How can I generate encoded HEVC bitstream using ffmpeg ?
31 octobre 2014, par jgmaoI am able to encoded YUV file to mp4 using HEVC :
ffmpeg.exe -f rawvideo -s 1920x1080 -pix_fmt yuv420p -i input.yuv -c:v hevc -r 30 -x265-params crf=27 -vframes 300 -an -y test.mp4Here is the mp4box -info test.mp4 shows :

Not all portions of video play well after concatenation
24 septembre 2018, par srgbndNode.JS 8.11.4, fluent-ffmpeg 2.1.2
I need to concatenate random portions of the same length of different videos in one video file. The concatenation proceeds without errors. But when I play the final concatenated file I see some portions playing well with sound, others have video "frozen" but sounds playing.
What’s the problem ? I want all portions playing well in the final concatenated file.
Concatenation config :
trex@cave:/media/trex/safe1/Development/app$ head concat_config.txt
file /media/trex/safe1/Development/app/videos/test/417912400.mp4
inpoint 145
outpoint 155
file /media/trex/safe1/Development/app/videos/test/440386842.mp4
inpoint 59
outpoint 69
file /media/trex/safe1/Development/app/videos/test/417912400.mp4
inpoint 144
outpoint 154
...In total, I have 16 portions of 2 videos. Duration of a portion is 10 sec. In the future the number of video files and portions will be much bigger.
trex@cave:/media/trex/safe1/Development/app$ ls -lh videos/test/

Ffmpeg converts video of double size of original video with second part without audio
21 janvier 2020, par mridul4cI am converting some videos with below command in ffmpeg
ffmpeg -y -i source.mp4 -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -crf 18 -b:v 4000k -maxrate 4000k -bufsize 4000k -vf "scale=-1:1080" destination_1080.mp4But in some cases the output video is exactly double size of the original and the second part is without audio. Please help.
