yes @manuel its getting bit hard even after setting
  -b:v 25M -minrate 25M maxrate 25M -bufsize 25M it not generating CBR mode
output and i will try for 1 & 2 pass once and convey you if i get the
constrained VBR

Re: [FFmpeg-user] MTS to MP4 lossless conversion issues

[akash kulkarni]

ffmpeg -i input -c:v copy -c:a aac -b:a 256k output.mp4

while executing

it gaves me error saying
[aac @ 02a802e0]
The encoder 'aac' is experimental but experimental codecs
are not enabled, add '-strict -2' if you want to use it.
[aac @ 02a802e0]
 Alternatively use the non experimental encoder
'libvo_aacenc'.

So i used
ffmpeg -i input.MTS -c:v copy -c:a libvo_aacenc -b:a 256k
mp4fro output.mp4

and it works .


i am just curious to know why aac is not working with my version of ffmpeg

Re: [FFmpeg-user] about merging Multiple videos together

[akash kulkarni]

Thanks ajoy,

I have
 Input #0, mpegts, from 'MTS_567i50_002.MTS':
 Duration: 00:01:32.15, start: 0.11, bitrate: 9424 kb/s
 Program 1
 Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p,
720x576
 [SAR 2304:2160 DAR 4:3], 25 fps, 50 tbr, 90k tbn, 50 tbc Stream
 #0:1[0x1100]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo,
 s16p, 192 kb/s

such kind of files which i wanted to merge with 720*576 resolution
These files has GOP size of 33, After i  merge them at each joint point
they jerk is coming
when i looked frames with some application there are few frames of next
video mixed with
previous video and sometimes few black frames also so how could i remove
such unwanted frames and
make my video smooth.

these videos Do have i frames after each 33rd frame so no question of key
frames would be there i guess.

so can you tell me solution over this.

[FFmpeg-user] About concat

[akash kulkarni]

I have few format files and need to perform merge operation on them.
MP4 format concatenate working fine but for MPEG , MTS it's giving me jerk
at two merge points. I used -copy command without re-encoding and combine
those from files from text file containing path & name of those files.
Those video just lose sync of audio and video at merge point can ffmpeg
help to sync them at the time of joining these files without re-writing
that header and file data
