Hi Brad,
Actually at that time I didn't explore much and since I already had my own
buffer class I quickly reused it. But if there are some other better
facility available in ffmpeg like libavcodec/audio_frame_queue.c I suggest
you cantry that.
Thanks
Pradeep

Like I spoke too soon, (I have also included time_base structure):
when tried on:
- FLV file: for r_frame_rate: {num=15 den=1 }, for avg_frame_rate: {num=0
den=0 }, for time_base: {num=1 den=1000 }
- WMV file: for r_frame_rate: {num=15 den=1 }, for avg_frame_rate: {num=0
den=0 }, for time_base:
Hello everybody
I am wondering if some of the developers of ffmpeg have any intention to
implement HEVC in ffmpeg ?
I know there is an open lib called openHevc https://github.com/OpenHEVC.
Any intention to work with ?
Regards

Hi
You have to specifie in the player the size of the picture of the YUV file
There is no header information about that in the yuv file !
Maybe you can try http://sourceforge.net/projects/raw-yuvplayer/

Hi guys,
I have come up with a quick patch:
//--
AVStream *st = pFormatCtx-streams[this-videoStream ];
if ( st-codec-codec_id == AV_CODEC_ID_H264 )//mp4
{
video_frame_rate= st-avg_frame_rate.num /
(double)st-avg_frame_rate.den;

Yes.

Unfortunately not.
Example:
1. dll (cio.dll) links statically to av.libs
2. dll (crecord.dll) links to both statically to av.libs and dynamically to
cio.dll
That gives me:

Hi, I am new to ffmpeg. I was able to compile ffmpeg for Android by
following the advice. But how can I compile a version that has the logging
using Android's logcat, i.e. the log should be displayed on logcat window.
Thx.

motion_val in AVFrame is now deprecated. I didn't see any reference to
alternate structures.
Is there any way, using the latest libav, to have access to decoded motion
vectors or has the capacity to export decoded motion vectors been removed
from libavcodec?
Thanks in advance.
